Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fibrous surface fastener having a female engaging element comprising at least a plurality of loops which are woven at the same time as the weaving of the woven fabric.

[0002]

2. Description of the Related Art A surface fastener of this type is generally composed of a male engaging member having a plurality of hook-shaped or mushroom-shaped male engaging elements erected on the surface of a flat base material, and a surface of the flat base material. A female engaging member having a large number of loop-shaped female engaging elements rising closely to the male and female engaging members by opposing the male and female engaging element forming surfaces and pressing the male and female engaging members. The engagement is disengaged when the engagement element and the female engagement element are engaged with each other and joined, or when the male and female engagement members are peeled off.

A hook-and-loop fastener having such a structure is used in a very wide range of fields from daily necessities to industrial materials. In recent years, a hook-and-loop fastener made of a fine shape has been used instead of a hook-and-loop fastener made of a woven or knitted fabric. Synthetic resin molded surface fasteners obtained by simultaneously molding a flat base material have been put into practical use, and are being used as fasteners for various diapers and sanitary articles that are easy to directly touch human skin. ing.

On the other hand, the most common structure of the female engaging member which engages with and disengages from the male engaging member is a so-called pile woven or knitted fabric having a large number of loops erected from the ground structure of a fiber woven or knitted fabric. Yes, usually, the pile (loop) is obtained by weaving or knitting the multifilament into the ground structure of a pile woven or knitted fabric. As other female engaging members, with the practical use of the engaging element having the fine shape of the integrally molded surface fastener described above, a general nonwoven fabric in which fine piles are densely formed on the surface has been used. ing.

[0005] In addition, a multifilament twisted yarn or a normal spun yarn is used as the yarn constituting the base fabric for weaving and supporting the male or female engaging element. This is because the monofilament or multifilament constituting the male or female engaging element is strongly gripped by the warp and weft woven structure by utilizing the frictional force due to the rough surface of the twisted yarn and the ease of deformation in the shearing direction. This is to prevent the engaging element from coming off the base material, and therefore the weaving density of the base material is all too large.

On the other hand, the use of this type of hook-and-loop fastener has become increasingly diversified, and even in the same industrial field, for example, in the field of clothing where fashionability is required, a hook-and-loop fastener adapted to the material, structure or coloring of the clothing is required. Request is strong. In particular, in recent years, hook-and-loop fasteners have been frequently used not only for underwear but also for outer garments.For thin clothing such as lace ground, for example, corresponding to those clothing materials or their structures, The fastener itself is required to be thin and transparent as a whole, and also to be flexible. Further, in addition to the above-mentioned requirements, a hook-and-loop fastener which is thin and has a large engaging force has been demanded in a wide range of fields such as various kinds of outer garments and detachable devices for bags and the like. In addition, for example, in the fastener portion of various sports clothing and bags,
Even though it is thick, it is required that various patterns and colors such as a logo mark attached to the main body can be visually recognized through the hook-and-loop fastener.

[0007]

However, even in the hook-and-loop fastener disclosed in the above-mentioned publication, a multifilament twisted yarn or a usual spun yarn is used for the warp and the weft constituting the base material. In addition to the fact that the weaving density of the base material itself is high and it is not possible to obtain a thin and flexible surface fastener, as is apparent from other examples disclosed in this publication, the conventional surface fastener, Many piles are densely grown on the surface of the flat base material by splitting the multifilament loop as described above for the female engaging member, and even if the flat base material is devised,
Since the piles are densely formed on the front surface, the back surface of the hook-and-loop fastener cannot be seen through, and the above-described problems cannot be solved.

For this reason, conventionally, a desired pattern, character, mark, or the like is applied to the surface of the product including the surface of the fastener after attaching the surface fastener, or a required pattern is applied to the surface of the surface fastener in advance. I have. In the case of the former, various problems are likely to occur due to the difference in dyeing properties between the hook-and-loop fastener and the attachment member such as clothing, and it takes two steps to apply a pattern or the like. In the latter case, not only the number of steps is increased, but also the complexity such as pattern matching when mounting the hook-and-loop fastener is increased, and the production efficiency is significantly reduced. Furthermore, the pattern on the pile surface, etc.
The form easily collapses, and a deviation from the pattern of the clothing main body occurs over time, and a difference in color clarity and the like easily occurs.

The present invention has been made to solve such a problem, and a first object of the present invention is to provide an extremely thin and flexible fiber fastener, and a second object is to provide a fiber fastener. It is an object of the present invention to provide a hook-and-loop fastener in which a pattern on the back side can be clearly seen through the engaging element and the base material. The third object is to improve the manufacturing efficiency of the hook-and-loop fastener, thereby increasing productivity and setting a reasonable price. It is to provide a hook-and-loop fastener which can be used.

[0010]

The above objects can be achieved by the present invention according to claims 1 to 12. The present inventors have conducted intensive studies based on the above-mentioned problems, and as a result, have found that a component member which has not been conventionally considered as a fiber surface fastener is optimal for solving the problems. That is, in the conventional fiber surface fastener, forming as many piles as possible in a dense state increases the engagement rate with a hook piece or the like, which is a mating male engaging element, and increases the peel strength. It was thought that the number would also increase.

On the other hand, in order to fix the engaging element to the base material regardless of whether it is male or female, it is necessary to increase the weave density of the base material and firmly restrain the base end of the engaging element with the warp and the weft. Although desirable, it has been found that anchoring the proximal end of the engagement element to the substrate is more dependent on the back coating than on the weave density of the substrate. Then, it is not necessary to use a twisted yarn for the warp and the weft as the constituent materials of the base material.

As a result of further investigation, as long as the pile shape is maintained as described above, even if the loop (pile) erected on the surface of the flat base material is a single thread, the male thread on the mating side is sufficient. It was also found that the engaging force with the engaging element and the peel strength were ensured.

[0013] In order to stably hold the loop on the surface of the substrate while maintaining the pile shape,
As disclosed in the above publication, usually, a synthetic resin may be applied to the back surface of the flat base material to fix the base end of the loop to the base material. However, in this type of hook-and-loop fastener, engagement and peeling are frequently repeated frequently, and if the fastening by the synthetic resin is weak, the fastening function may be lost within a short period of time. To avoid this, it is necessary to increase the amount of the synthetic resin applied to the back surface of the base material. This increase in the amount of resin not only causes the flexibility of the flat base material to be lost, but also reduces the transparency of the flat base material, for example, when the flat base material itself is formed thin. This means that it is not possible to cope with the diversification of the above-mentioned hook-and-loop fastener, and its use is also limited.

Therefore, the present inventors have further studied and found that even if the amount of the synthetic resin applied to the back surface of the base material is reduced, the material of the synthetic resin to be applied and the material of each thread constituting the surface fastener are appropriately determined. In addition, it was found that when the back surface of the base material was appropriately coated with a synthetic resin, a loop capable of maintaining a pile shape with sufficient durability could be formed.

[0015] The invention according to claim 1 of the present invention relates to a hook-and-loop fastener having a large number of engaging elements which are woven at the same time as the weaving of a base fabric made of a ground texture and project from the surface of the fabric. The main structure is a fiber surface fastener characterized in that all of the warps, wefts and yarns constituting the engaging element are made of monofilament.

Here, the surface fastener made of fiber in the present invention is composed entirely of fiber yarns, and a plurality of male or female engaging elements are independently provided on one surface of the woven fabric, or Male engaging element and female engaging element are mixed,
It also includes so-called self-engaging surface fasteners that can engage and disengage by themselves.

The most characteristic point of the present invention is that not only the warp and the weft constituting the ground structure but also the thread for the engaging element folded therein are made of monofilament. It is. In this way, by using monofilaments as all the constituent yarns of the hook-and-loop fastener, the weaving preparation process is simplified, productivity is improved, and at the same time, the thick hook-and-loop fastener is selected by selecting the fineness of each constituent yarn. To extremely thin hook-and-loop fasteners. Furthermore, if the weaving density is set low, voids can be formed between the woven structures of the warp, the weft, and the monofilament for the engaging element, and even if the female surface fastener is used, the engaging element is also the same. Since it is made of a monofilament, transparency can be ensured.

According to a second aspect of the present invention, a synthetic resin applied to the back surface of the base fabric is used to firmly fix the engagement element made of a monofilament to the base fabric and to secure the transparency. The warp, the weft and the monofilaments forming the engaging element are intensively attached to the intersections of the monofilaments, and a gap is formed between the warp, the weft and the woven fabric of the monofilaments forming the engaging element.

Claims 3 to 5 define the form and function of the engaging element, and the invention according to claim 3 is a female engaging element in which the engaging element is a loop, and a surface obtained by the female engaging element. The fastener is a female hook-and-loop fastener. The invention according to claim 4 stipulates that the engaging element is a hook-shaped or mushroom-shaped male engaging element, and the obtained surface fastener is a male surface fastener. Further, the invention according to claim 5 is characterized in that the plurality of engaging elements are composed of a female engaging element formed of a loop and a male engaging element of a hook or mushroom shape, and these engaging elements are mixed. It defines a so-called self-engaging type surface fastener.

The inventions according to claims 6 to 8 define a preferable range of fineness of each yarn constituting the material of the hook-and-loop fastener. According to claim 6, the monofilament constituting the female engaging element is 2d to 70d, and the monofilament constituting the male engaging element is 100d according to claim 7.
d to 150d, and in claim 8, the warp constituting the ground structure is 2d to 100d and the weft is 30d to 100d.
d.

Within such a fineness range, by appropriately combining these, the required engaging strength and peeling strength as a surface fastener can be obtained, and it is thinner and more flexible than ever before, and the front and back can be seen through. A hook and loop fastener that can be obtained is obtained.

The invention according to claim 8 defines the fineness of the male engaging element when manufacturing the self-engaging surface fastener. That is, the yarn constituting the ground structure is 2d to 100d, the monofilament for the female engaging element is 2d to 70d, and the monofilament for the male engaging element is 70d to 300d. In the present invention, the fineness of a monofilament, which is a constituent thread of the male engaging element, is set to 70d to 70d.
The reason for defining 300d is to secure a required engaging force between the female engaging element and the female engaging element. Those numerical values are appropriately determined by the use of the hook-and-loop fastener and the fineness of the female engaging element. is there.

According to a ninth aspect of the present invention, the hook-and-loop fastener is intended to further enhance transparency, and all the monofilaments are made of a transparent or translucent material.

Applying a synthetic resin material to the back surface of the woven fabric to form a thin film, blowing gas from the back surface of the woven fabric toward the front surface, and applying the film to each of the constituent yarns of the woven fabric. Including focusing at the intersection,
The convergence forms gaps between the constituent yarns of the hook-and-loop fastener so that the front and back sides penetrate.

According to the eleventh aspect, the engaging element includes one or both of a female and a male. When the male engaging element is a single element or the male and female engaging elements are mixed, The most typical method of forming a male engaging element is to cut a part of the loop, which is a constituent material of the male engaging element.

The form of the male engaging element is not limited to the hook-shaped male engaging element obtained by the above-described manufacturing method. For example, the male engaging element for the male engaging element woven as described above is used. In some cases, a so-called mushroom-shaped male engagement element having a hemispherical engagement head at the tip thereof, while melting and cutting the vertex of the loop.

[0027]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a partial perspective view showing a first embodiment of a woven surface fastener according to the present invention having a woven structure, and the woven surface fastener has a large number of loops on one surface of a ground fabric. An example of a female surface fastener in which is formed. In the figure, reference numeral 1 denotes a base fabric, 2 denotes a warp, 3 denotes a weft, and 4 denotes a monofilament for a female engaging element.

In the female engaging member of the present embodiment,
Is composed of a plain weave design comprising a warp 2 and a weft 3, and a 30d monofilament is used as the warp 2 which is a feature of the present invention.
A 0d monofilament is used. FIG.
Shows a double yarn consisting of two monofilaments in this example, because this embodiment uses a double pick in which reciprocal weft insertion is performed in one opening because weft insertion is performed by a carrier. A single monofilament is used for weft insertion. Therefore, in the case of a normal loom, each weft 3 is completely constituted by a single monofilament.

Further, in the present embodiment, a thread for a female engaging element in which a multifilament is conventionally used is woven into the ground fabric 1 which constitutes another feature of the present invention. A single monofilament 4 is used as a thread for the female engagement element, and the monofilament 4 is woven into the ground fabric 1 while forming a loop 4a. According to this embodiment, the monofilament 4 for the female engagement element is used.
Has a fineness of 30d.

In this embodiment, polyester is used for the warp 2, the weft 3, and the monofilament 4 for the female engaging element. However, usually, polyamide, polypropylene, etc. used for this type of hook-and-loop fastener are used. Can be used alone or in combination. In this embodiment, the fineness of each yarn is set as described above and a highly transparent polyester is used in order to secure the see-through property of the surface fastener. The present invention is not intended only to ensure transparency, but is based on the premise that a monofilament is used as a thread for a female engagement element in consideration of productivity and economy.

Also, in this embodiment, since the weaving weaves the weft yarn 3 using the carrier, one yarn reciprocates in the same opening of the warp yarn, and two weft yarns 3 are always aligned. In addition, a so-called twin yarn state is obtained. Therefore, the fineness of the weft 3 is doubled. In this embodiment, the number of hits per inch of the weft 3 is 57 to 58, which is considerably larger than the usual 52 times / in. Nevertheless, the reason why the transparency is ensured is that, as described above, the fineness of all the constituent yarns uses monofilaments which are extremely small as compared with the conventional ones. This is because voids exist between the warp yarns. In addition, the warp density in this example is 120 to 13
Although it is 0 threads / in, the weft density and the warp density may be determined according to the use of the surface fastener according to the present invention.
Since this fineness is small, the obtained surface fastener is
It becomes extremely thin as a whole.

Next, an example of a specific woven fabric structure of the hook-and-loop fastener of the present invention woven using the yarn having the above configuration will be described with reference to FIG. In the figure, the warp yarn 2 and the weft yarn 3 constituting the base fabric 1 and the monofilament 4 constituting the female engaging element are all 30d.
Monofilament is used. Therefore, as described above, the weft yarn 3 is made of a twin yarn, and is 60d. The fabric of the ground fabric 1 is composed of a plain weave fabric of the warp 2 and the weft 3. Then, a warp row w in which two adjacent warps 2 are set as one set
The monofilaments 4 forming the loops 4a for the female engagement elements are woven every time one row is skipped. In this case, the loop 4a of the monofilament 4 is laid down next to the next weft 3 after jumping down one weft 3 as shown in FIG. Over the set of warp rows w, the next weft 3 is sunk and formed successively. Such a woven structure is a general woven structure of a conventional male fastener, and the monofilament 4 which is a constituent thread of the female engaging element is composed of 3 wefts 3.
After weaving into the book, a new loop 4a is formed while straddling the warp row w.

Of course, the weaving structure shown here is merely an example of the present invention. For example, it is possible to form a loop by the monofilament 4 for every other weft yarn 3, and in this case, the loop density increases. The engagement ratio with the male engagement element of the other party increases. In addition, in the case of this weaving structure, it is more preferable to form each loop 4a while straddling a pair of warp rows w in a zigzag manner so as to give the loops various directions.

The woven fabric woven as described above is heat-set on a loom according to a conventional method to fix the ground weave structure and the form of the loop. The resin material is fixed to the base fabric 1. In order to further secure flexibility and transparency in addition to stabilizing the loop form, the resin material is made of the same kind of material having high adhesiveness to each constituent yarn. , The coating amount is made as small as possible and the loop 4a
It is desirable to concentrate on a contact portion between the base portion of the base material and the ground fabric 1.

Therefore, in the present embodiment, since the synthetic resin material is applied to the woven hook-and-loop fastener as described above, a heating zone 11 is provided near the weaving front of the loom 10 of the hook-and-loop fastener as shown in FIG. A roller coating unit 12 for applying a synthetic resin material to the back surface of a hook-and-loop fastener provided with a scraper 13 is provided further downstream of the heating area 11, and an air nozzle 14 is provided adjacent to the downstream portion. It is arranged toward the back of the fastener. The loom 10
Usually, a tape loom is used, but a normal loom can also be used.

Now, the hook-and-loop fastener having the above-described structure woven by the loom 10 is set by heating in a heating zone to fix the weaving form, and then a synthetic resin material diluted with a solvent is coated on the back surface. It is applied via a roller 12a. The film thickness is adjusted by the scraper 13, and a thin film is formed on the entire back surface of the hook-and-loop fastener. When the hook-and-loop fastener reaches the installation portion of the air nozzle 14 in this state, air is blown to the thin film from the back side to the front side of the hook-and-loop fastener. With this air, each constituent yarn 2,
The thin film formed in the gap existing between 3, 4 is broken and gathers at the intersection of the constituent yarns 2, 3, and 4, and the intersection is locally joined and the gap is formed. Through.

In this way, the synthetic resin material gathers at each intersection of the warp 2, weft 3, and monofilament 4 for the female engaging element, which are constituent yarns of the hook-and-loop fastener, and intensively synthesizes each constituent yarn at the intersection. Since the resin material is used for bonding, the shape of the loop 4a, which is a female engagement element, is firmly fixed without collapse, and a gap is formed between the constituent yarns so that the front and back sides penetrate. Coupled with the fact that 3 and 4 are transparent, it is possible to more clearly see through the back surface side from the front surface of the hook-and-loop fastener.

In this embodiment, since the transparency is ensured in this manner, even if the hook-and-loop fastener is directly attached to a bag or an outer garment provided with various patterns or characters, The surface fastener allows the pattern or the like to be seen through from the surface of the fastener. Further, it is also possible to apply, for example, a logo mark, various patterns, characters, or a color to each of the back surface of the hook-and-loop fastener. on the other hand,
In the conventional hook-and-loop fastener, because the lack of transparency, when applying a color or the like, it has to be applied directly to the surface on which the engaging element of the hook-and-loop fastener is formed. The deformation of the engaging element causes a difference in the sharpness between the engaging element and the peripheral pattern, or the pattern is distorted. In this regard, according to the present invention, since the pattern or the like is applied to the back surface of the hook-and-loop fastener, that is, the attachment surface of the counterpart article, the above-described problem does not occur.

FIG. 3 shows a male fastener according to a second embodiment of the present invention.
The fineness of the weft yarn 3 is 30d, as in the first embodiment, and the fineness of the monofilament 5, which is a constituent yarn of the male engaging element, is 150d, which is smaller than the other yarns. Extremely fine fineness, but the fineness of a conventional monofilament for a male engaging element is 200d-3
Considering that it is 50d, it can be understood that it is extremely thin.

In this embodiment, the fineness of the monofilament 5 for the male engaging element is made larger than the fineness of the other constituent yarns 2 and 3 as described above in order to secure the engaging force. However, the fineness can be appropriately determined depending on the application. However, in order to ensure the transparency of the hook-and-loop fastener as a product, the fineness is desirably 150 d or less.
Desirably, it is not less than 00d. The material of each yarn used in this embodiment is a polyester having transparency as in the first embodiment.

FIG. 4 shows a self-engaging hook-and-loop fastener according to the present invention, in which male and female engaging elements are mixed on the same surface of the ground fabric 1. In this embodiment, the fineness of the warp yarn 2 and the weft yarn 3 of the ground fabric 1 are both 30d monofilaments as in the first embodiment, and the fineness of the monofilament 4 constituting the thread of the female engaging element. Also, the fineness of the monofilament 5, which is a constituent thread of the male engaging element, is 150d similarly to the above embodiment. In this embodiment, as described above, the fineness of the monofilament 5 for the male engaging element is made larger than the fineness of all of the other constituent yarns 2, 3, and 4, as in the above-described embodiment. For reasons.

Thus, the fabric structure according to this embodiment is substantially the same as that of the first and second embodiments, except that the loop 4a which is a female engaging element and the loop 5a which is a male engaging element.
a in that they are alternately arranged in the weave width direction. That is, the monofilaments 4 for the female engaging element in the first embodiment are replaced with the monofilaments 5 for the male engaging element every other one.
Therefore, the weaving structure of the monofilaments 4 and 5 is not different from that of the first and second embodiments as a whole.

However, in the present embodiment, the monofilament 4 for the female engaging element and the monofilament 5 for the male engaging element have a difference in fineness as described above. The form of the engagement element is such that it can engage with the female engagement member. However, even in the present invention, the male engaging element does not need to have a special form or function different from the conventional one, and a normal engaging element obtained by cutting a part of the loop 5a for the male engaging element is used. What is necessary is just a so-called mushroom-shaped engagement element having a hook piece or the upper end of the loop 5a melt-cut and having a hemispherical engagement head at its tip.

After the loop woven fabric having the above-described woven structure is woven, heat setting and formation of a thin film on the back surface are performed in the same manner as in the first embodiment, and then the loop 5a for the male engagement element is formed in a conventional manner. Only the hook piece 6 which is a male engaging element is partially cut off. Even in the present embodiment, the hook-and-loop fastener obtained in the same manner as in the first embodiment ensures flexibility and transparency, and it is natural that the engaging element surfaces of the hook-and-loop fasteners having the same structure are pressed against each other. Thereby, it is possible to join with a required engagement strength and to easily peel off.

The above description describes preferred embodiments of the present invention, and the present invention is not limited to these embodiments. For example, if the present invention does not adhere to transparency or flexibility, The fineness of the warp and the weft of the ground fabric can be set to a normal fineness, and the weaving density can be appropriately selected.
