Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a woven fabric using a composite yarn containing ultrafine fibers, which is excellent in bulge and drape and has a fluff on the surface which exhibits a different color effect.

[0002]

2. Description of the Related Art Conventionally, various napped products having a natural leather-like sensation have been developed, and how a combination of microfibers and nap technology can be used to produce fluffs of microfibers on the surface with high density and uniformity. About the development has been promoted.

As a typical example thereof, there is one in which ultrafine fibers are formed into a non-woven fabric, and naps are obtained by raising the surface fluff uniformly by raising the fibers.

However, since the structure based on this non-woven fabric is easily raised, ultrafine fibers are evenly arranged on the surface, and a backskin, suede or similar natural leather-like structure can be obtained, but the basis weight is Since it is large and quite thick, and has poor drapeability, it has the drawback that it can only be applied to limited applications such as blazer and coat.

On the other hand, as a method for enhancing the raising property by using a structure based on a woven or knitted material, Japanese Patent Publication No. Sho 61-407.
In Japanese Patent No. 78 and Japanese Patent Publication No. 63-23309,
A method has been proposed in which ultrafine fibers and high-shrinkage yarns are used as mixed-fiber composite yarns, and the method is used as a weft yarn of a woven fabric to heat the fabric to shrink the high-shrinkage yarns of the composite yarns to enhance the raising effect of the ultrafine yarns. .

[0006] However, these methods are merely aimed at the effect of the thickness and structure of the thread which is easily raised as a fabric structure, and the surface is covered with fluff as compared with the conventional non-raised fabric. Therefore, although it is excellent in softness of raised hair, it is inferior in terms of bulge and drape, so it cannot be applied to garments such as suits and dresses, and it has the drawback that it cannot express a feminine silhouette.

Furthermore, conventional brushed fabrics aiming at natural leather are only approached as close as possible to touching the condition of the surface of the natural leather, and have an excellent bulge, drape and different color effect. It was not something that could be expressed.

[0008]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems of the prior art and has excellent swelling and drape properties even though it is a natural leather-like woven fabric. Furthermore, it is not a natural leather-like surface effect but a synthetic one. An object of the present invention is to provide a woven fabric having a novel surface effect of a different color which can be obtained only by using fibers.

[0009]

The present invention has the following constitution in order to achieve the above object.

That is, each of the warp and the weft is 2%.
In a woven fabric composed of different shrinkage mixed yarns having the above shrinkage difference, a low shrinkage polyester multifilament yarn having a single fiber fineness of 0.5d or less (hereinafter sometimes simply referred to as "ultrafine yarn") and a single fiber as the weft yarn. Single-filament fineness that has a yarn composed of a low-shrinkage polyamide multifilament yarn having a fineness of 1d or less (hereinafter sometimes simply referred to as “polyamide yarn”) and a high-shrinkage multifilament yarn having a fineness of 1d or more, and that constitutes the weft. The low shrinkage multifilament yarn of 0.5d or less and the polyamide low shrinkage multifilament yarn of single fiber fineness of 1d or less have fluffs, and further the warp is 3
It is a woven fabric having fluff on the surface, which has a real twist of 50 T / M or more.

The present invention will be described in detail below.

The present invention is a woven fabric in which the warp yarn and the weft yarn constituting the woven fabric are heterogeneous shrinkage mixed yarns each having a shrinkage difference of 2% or more. The warp yarn and the weft yarn have the following constitutions. The effect of the fabric can be obtained.

First, the warp in the present invention will be described in detail.

In the present invention, the warp is a heterogeneous shrinkage difference mixed yarn that exhibits a difference in shrinkage during boiling water treatment.
It is important to have a true twist of M or more. Preferably,
Those having a real twist of 500 T / M or more are preferable.

The number of actual twists to be given to the warp is 100 to 200 in a region called sweet twist for the purpose of improving the usual process passability.
With T / M, it is difficult to obtain a preferable drape property. On the other hand, from the viewpoint of not reducing the drape property, 2000T /
It is preferably M or less. A more preferable range of the actual twist number is 350 to 1500 T / M. A double twister is suitable as a method for giving a real twist.

By using as the warp a different shrinkage mixed yarn to which a real twist is applied, a draping drape with a bulge which has not been obtained in the conventional suede-like woven fabric is realized, and in the woven structure point. By exposing a part to the woven fabric, it is possible to realize a new surface feeling which was not obtained in the conventional suede tone in combination with the weft yarn type, the woven structure and the dyeing processing conditions.

In order to obtain appropriate swelling and drapability, it is important that the different shrinkage mixed yarn to be used has a shrinkage difference of 2% or more as a difference in boiling water shrinkage between the low shrinkage side and the high shrinkage side. The difference in shrinkage is preferably 5% or more. A low shrinkage multifilament yarn has a shrinkage rate of 8% or less in boiling water treatment, and a high shrinkage multifilament yarn has a shrinkage rate of 1 in boiling water treatment.
A multifilament yarn of 0% or more and 35% or less is preferably used. It is more preferable that the shrinkage ratio of the high shrinkage multifilament yarn is 13% or more and 30% or less.

The different-shrinkage mixed yarn is composed of yarns obtained by using ordinary polyethylene terephthalate under different drawing conditions, or polyethylene terephthalate is copolymerized with isophthalic acid, 5-sodium sulfoisophthalic acid component and the like. The polyethylene terephthalate copolymer may be used as a highly shrinkable yarn.

Further, as the third component, additives such as a matting agent, an oxidizing agent, a coloring agent, a flame retardant and a lightproofing agent may be contained.
It is preferable that the heterogeneous shrinkage mixed yarn contains 0.8% by weight or more of inorganic particles, since higher drapeability can be imparted to the woven fabric by reducing the alkali. Content of inorganic particles is 1.0
It is more preferably at least wt%, and even more preferably at least 1.2 wt%. As the inorganic particles, typical ones such as titanium oxide and calcium carbide which can be added during polymerization of polyester may be used, and in addition, silicon oxide, zirconia oxide, kaolin, calcium carbonate and the like can be used. Of these, titanium oxide is preferable.

As the different-shrinkage mixed-fiber yarn constituting the warp, a polyester fiber having a single fiber fineness of 10 denier or less can be appropriately adopted without being specified.

The composition ratio (weight ratio) of the low-shrinkage component and the high-shrinkage component of the different-shrinkage mixed fiber yarn constituting the warp is 80:
It is preferably from 20 to 20:80, and from 60:40.
It is more preferably 40:60.

As the different-shrinkage mixed fiber yarn constituting the warp yarn, it is possible to use a superfine yarn in order to obtain the surface touch more effectively. In this case, ultrafine yarn may be used as the low shrinkage component, or a composite yarn containing the ultrafine yarn as the low shrinkage component and the high shrinkage component may be used.

As the structure of the composite yarn, there are a method of ply twisting a different shrinkage mixed filament yarn and an ultrafine yarn, a method of entanglement by an air treatment, and a method of entanglement by an air treatment followed by additional twisting. Although it can be adopted, as described above, it is important to have a real twist of 350 T / M or more as the warp of the woven fabric.

When the ultrafine yarn is used as the constituent yarn of the warp yarn, it is possible to impart a soft texture and an excellent drape property to a woven fabric. Although the denier and composition ratio of the ultrafine filament yarn can be changed according to the denier of the filament yarn other than the ultrafine yarn, the desired texture and drape can be imparted to the woven fabric, but the composition ratio of the ultrafine yarn is 80% of that of the warp yarn. %
If it exceeds the range, it is not preferable because it is too soft due to the relation between the bulge and the drape property and the tailoring appearance in garment is deteriorated.

The ultrafine yarn referred to in the present invention preferably has a single fiber fineness in the range of 0.01 to 0.5 denier (d), and as a kind, it is an undrawn yarn or a semi-drawn yarn spun from an ordinary spinneret. A drawn yarn obtained by drawing a drawn yarn in a drawing step,
Any of high speed spun yarn by one step of high speed spinning, sea / island type, or split fiber type can be adopted.

In order to express the raising effect required for the fabric, the soft swelling feeling of the surface change, the drape property, and the excellent silhouette and tailored appearance in garment,
The ultrafine yarn has a difference of 0.5 denier or more, preferably 1 denier or more, more preferably 2 denier or more, from the other constituent filament yarns and single fiber denier. Although preferable, it can be appropriately selected in relation to the weft. If it is less than 0.5 denier, the garment lacks firmness and firmness, the tailored appearance of the garment is inferior, and the garment type is restricted, which is not preferable.

Further, in the present invention, it is preferable that at least a part of the warp yarn is exposed on the surface of the fabric at the texture point of the fabric. In the conventional suede-like woven fabric, it was a necessary condition that the surface of the woven fabric be uniformly covered by raising the ultrafine yarn of the weft yarn. However, in the present invention, the warp yarn and the weft yarn in one complete design of the woven fabric are interlaced. It is not necessary for the weft fluff to completely cover the warp at the weft design point. In the present invention, it is preferable to have a portion where the warp yarns are present on the woven fabric surface so as to be exposed on the woven fabric surface because the effect of improving the touch and color tone change of the woven fabric surface is great. This exposed part is usually hard to see with the naked eye,
It can be confirmed by using a stereoscopic microscope of 0 times or more.

For example, at a woven fabric design point of one complete design in 5 sheets of satin, 0 to 3 places of 5 warps are randomly exposed between wefts having napped ultrafine yarns as one constituent yarn. By doing so, a change in the color tone of the surface of the woven fabric is produced, and a surface change which is not present in the conventional suede-like woven fabric is obtained.

Next, the construction of the weft will be described.

The weft yarn mainly contributes to a new surface effect in the dyeing and finishing process of the woven fabric.

In the present invention, the weft yarn is a different shrinkage difference mixed yarn that exhibits a shrinkage difference of 2% or more in boiling water treatment, and as the fluff component of different colors, ultrafine yarn and polyamide yarn are low shrinkage components and high shrinkage components. It is important to use a filament yarn having a single fiber fineness of 0.5 denier or more than the ultrafine yarn. The high shrinkage component may be a composite yarn composed of different shrinkage mixed yarns.

The ultrafine yarn constituting the weft yarn preferably has a single fiber denier in the range of 0.01 to 0.5 denier, and as a kind, an undrawn yarn or semi-undrawn yarn spun from an ordinary spinneret is drawn. Drawn yarn obtained in the step, high-speed spun yarn by one step of high-speed spinning, sea / island type, or
Any split fiber shape or cross-sectional shape such as round or irregular shape can be used without limitation.

The monofilament denier of the polyamide yarn is preferably 1 denier or less, more preferably 0.5 denier or less in order to form the same fluff component as the ultrafine yarn. The types of polyamide yarn include undrawn yarn or semi-undrawn yarn spun from an ordinary spinneret, drawn yarn obtained by drawing in a drawing process, high-speed spun yarn by one high-speed spinning process, sea / island type, or split fiber type. Any of the above and cross-sectional shapes such as circles and irregular shapes can be adopted without limitation.

The multi-filament yarn having a high shrinkage component that constitutes the weft yarn is composed of yarns obtained by using ordinary polyethylene terephthalate under different drawing conditions, or polyethylene terephthalate with isophthalic acid, 5
-A polyethylene terephthalate copolymer in which a sodium sulfoisophthalic acid component or the like is copolymerized is configured as a highly shrinkable yarn, and the like. However, if the single fiber fineness is 0.5 denier or more than the ultrafine yarn, Single fiber fineness 10
A polyester fiber having a denier or less can be appropriately adopted without being specified. Preferably, an isophthalic acid copolymerized polyester having excellent alkali resistance when the cloth is treated with an alkali is preferable.

Further, as the third component, additives such as a matting agent, an oxidizing agent, a coloring agent, a flame retardant and a lightproofing agent may be contained.
It is preferable that the heterogeneous shrinkage mixed yarn contains 0.8% by weight or more of inorganic particles, since higher drapeability can be imparted to the woven fabric by reducing the alkali. Content of inorganic particles is 1.0
It is more preferably at least wt%, and even more preferably at least 1.2 wt%. As the inorganic particles, typical ones such as titanium oxide and calcium carbide which can be added during polymerization of polyester may be used, and in addition, silicon oxide, zirconia oxide, kaolin, calcium carbonate and the like can be used. Of these, titanium oxide is preferable.

As the structure of the weft yarn, a crimped yarn subjected to false twisting, a yarn having a substantial actual twisting effect by compounding in a composite form, an ultrafine yarn, a polyamide yarn and other multifilament yarns are air-treated. It is possible to use the mixed fiber obtained by the mixed entanglement by the above, or the one in which the additional twist is applied after the mixed entanglement is performed by the air treatment. Further, the false twisting of the ultrafine yarn and the polyamide yarn is performed by adding crimp to the yarn and imparting bulkiness, and further, the shrinkage is promoted by the heat treatment effect of the false twisting, and the raw yarn of the partner to be mixed This is preferable because the difference in shrinkage with the high shrinkage yarn is further expanded, and both are more floated on the surface of the woven fabric, which facilitates raising hair. The false twisting conditions for both may be the conditions for ordinary polyester yarns and polyamide yarns.

When false-twisting the ultrafine yarn and the polyamide yarn, the types of both are obtained by the spinning-drawing method,
Regardless of whether it is a high-speed spinning one-step method, a sea-island type, or a split fiber type, the false-twisting type may be any of the ordinary pin false-twisting type, friction false-twisting type, and air false-twisting type. As the false twisting condition, the heater temperature is usually within the range of the specifications of the false twisting machine, for example, 150 ° C to
A temperature of 220 ° C. is sufficient because it can impart bulkiness that contributes to bulging. The heater may be two heaters, but one heater that is excellent in bulkiness and inexpensive in cost is preferably adopted. For the false twist number, in order to impart bulge, softness, and raising property, it is advisable to adopt a condition in which the yarn processability is stable so that the crimping characteristic of the usual woolly processed yarn can be obtained.

As the entanglement method, a method called normal interlacing or a method called Taslan processing can be adopted, but interlacing is preferable because the weft of the present invention does not require fluffs or loops. Furthermore, the additional twisting after the entanglement is performed by using the ultrafine yarn, the polyamide yarn, and the high shrinkage yarn.
It is important for making the mixed fibers more uniform and improving product quality, and the twisted yarn is preferably 100 to 300 T / M.

As for the mixed fiber form of the weft yarn, when the fabric is buffed in the dyeing process, it is not necessary that the ultrafine yarn and the polyamide yarn are raised and fluffed to uniformly cover the entire face of the fabric,
A part of the multifilament yarn other than the ultrafine yarn and the polyamide yarn may be exposed.

Surface fluff caused by raising of the ultrafine yarn and polyamide yarn, swelling feeling of differently contracted mixed yarn or composite yarn of warp yarn, drape property by actual twisting, and ultrafine yarn, polyamide yarn and high shrinkage yarn or different The effect of randomly changing the hue of the shrunk mixed-fiber yarn can be designed by combining the warp and weft, but basically, the weft and warp are easily cut by buffing in the dyeing process of the fabric. The mixed state, texture and state of

As a combination of warp and weft for having a soft feel, excellent drapeability, and a new feeling on the surface, the weft contains a superfine multifilament having a single fiber denier of 0.5 denier or less. Is important and need not necessarily be included in both warp and weft simultaneously. Further, it is important that the polyamide yarn is mixed with the ultrafine yarn in the weft yarn in order to enhance the effect of different color (color change).

When the warp is a heterogeneous-shrink mixed yarn that does not contain ultrafine yarn having a denier of 0.5 denier or less, the weft yarn has a high content of ultrafine yarn having a denier of 0.5 denier or less. Good. The composition ratio (weight ratio) of the ultra-fine yarn and the polyamide yarn constituting the weft is 80:20 to 30: 7.
It is preferably 0, more preferably 70:30 to 50:50. When the composition ratio of both is high, the shrinkage force of the high shrinkage yarn of the mixed fiber becomes insufficient, while when the composition ratio of both is low, the texture of raised hair tends to be unobtainable. In addition, the composition ratio (weight ratio) of the polyamide yarn to the ultrafine yarn is preferably 50% or less, and more preferably 30 from the viewpoint of obtaining excellent discoloration and surface touch.
% Or less.

In the case of a composite yarn containing a superfine yarn having a single fiber fineness of 0.5 denier or less in the warp, the composition ratio of the superfine yarn constituting the weft and the yarn containing the polyamide yarn is 60:40.
It is preferably ˜20: 80. In addition, as the constitution of the weft in the woven fabric structure, a composite yarn containing an ultrafine yarn and a polyamide yarn, or a multifilament yarn containing no ultrafine yarn and a polyamide yarn may be alternately arranged. It may be a strong twist yarn which is used for a normal 100% polyester thin fabric as a multifilament yarn which does not include an ultrafine yarn and a polyamide yarn. In this case, a woven fabric having fluff on the surface, which exhibits particularly excellent drapability, is obtained.

The woven structure having a raised surface, touch and drape is not particularly limited, and the single fiber fineness of 0.
The design may be performed in consideration of the effect of buffing in buffing in the dyeing process depending on the amount of ultrafine fibers having a denier of 5 or less contained in the weft and the warp.

Next, an example of a method for manufacturing a woven fabric will be described.

As a warp, a different shrinkage mixed yarn having a shrinkage difference of 2% or more is applied with a twisting machine of 350 T / M or more by a twisting machine generally used in a weaving process. In this case, a yarn having a large shrinkage and a yarn having a shrinkage of 2% or more lower than that may be aligned and plied. When the number of twists of the obtained twisted yarn is large, twist setting is performed to improve process passability.

As the weft yarn, a super-fine yarn, a polyamide yarn, and a high shrinkage yarn are aligned and interlaced to give a light entanglement. It is important that the difference between the shrinkage ratio of the high shrinkage yarn and the shrinkage ratio of the ultrafine yarn and the polyamide yarn on the low shrinkage side is 2% or more. The difference in shrinkage can be determined by the method of designing the original yarn, the method of reducing the shrinkage of the ultrafine yarn and the polyamide yarn side during the interlacing treatment by a normal heat treatment with a hot plate, or the method of false twisting as the shrinkage reducing treatment. Can be obtained by For example, when both the ultrafine yarn and the polyamide yarn are false twisted, or even when the ultrafine yarn is false twisted and the polyamide yarn is raw yarn, the shrinkage difference of 2% or more with the high shrinkage yarn If there is

Next, twisting yarn is applied to the composite yarn composed of the ultrafine yarn, the polyamide yarn, and the high shrinkage multifilament yarn, in order to impart additional twist. Twisted yarns can be used as weft yarns even if they are not carried out, but in order to make the mixture of ultrafine yarns, polyamide yarns and high shrinkage yarns more uniform, 100-300T
It is preferable to impart a twist of / M. This additional twist has the opposite effect in raising the weft when the surface of the fabric is uniformly covered with the raised fluff in the conventional suede-like fabric, but in the fabric of the present invention, the entire surface is uniformly covered with the fluff as in the conventional case. Since it is not necessary, additional twist of 100 to 300 T / M can be adopted.

The obtained warp is warped by an ordinary coarse winding warp or partial warper, passed through sizing, and set on a loom.

The loom can be adopted as a general loom, a rapier, a water jet loom, an air jet loom and the like without any particular limitation. Of these, a water jet loom, which is widely used for filament woven fabrics, is preferable from the viewpoint of cost and productivity.

The woven structure to be selected in weaving is not fixed in relation to the constituent yarns and the number of twists, but is appropriately selected depending on the required texture of the woven fabric.

The obtained greige is put into a dyeing process. It is the dyeing process described below that causes the fabric designed as described above to obtain the desired characteristics to exhibit the surface touch of the raised fabric, the drape property, and the swelling feeling.

In the dyeing process of the woven fabric of the present invention, it is essential to obtain a raised surface effect having swelling and drape properties, and the conditions are set on the basis of the normal dyeing process.

In the weaving machine, an oil agent and a sizing agent are attached in the weaving process, and at the same time, a scouring / relaxation treatment is performed in order to fully exert the difference in shrinkage of the warp and the weft To do. The treatment condition is preferably a condition in which tension and temperature are controlled to give a fir effect and a swelling feeling is exerted on the fabric. Specifically, for example, in a temperature range of 100 ° C. to 120 ° C. It can be employed in any of continuous type, batch type and the like.

After the scouring and relaxing steps, the product is dried and a preset tense is set.

Next, an alkali weight reduction treatment is carried out in order to reduce the friction at the crossing points of the warp yarns and the weft yarns constituting the fabric and to provide the drape property by the sea removal treatment (in the case of the sea / island extra fine yarn). The condition may be a range applicable from the condition of ordinary woven fabric.

Then, the obtained woven fabric is subjected to a sanding (buffing) process to cut a portion of the ultrafine yarn of the weft yarn and the polyamide yarn to generate fluff. The buffing condition controls the napped state depending on the roughness of sanding, the number of rotations of the roller, and the method of applying a force for contacting the woven fabric with the sanding roller. It is preferable to perform a raising process with a short fluff because it is easy to form a state in which at least a part of the warp yarn having a real twist is exposed to the woven fabric at the woven fabric texture point. When the strength of sanding is increased, a part of the warp may be cut, but fluff may be included in the warp as long as the effect of the present invention is not impaired.
The sanding process is preferably performed twice before dyeing and before finishing. On the other hand, the raising process with the raising of the needle cloth is not preferable because it is likely to be deeply raised and to be entirely raised.

In this sanding process, in the conventional suede-like woven fabric, it has been an essential condition that the weft yarns are raised as much as possible and raised so that the warp yarns cannot be seen to cover the surface with uniform fluff. In the case of using a different shrinkage mixed yarn having a real twist as the warp and buffing, the fabric surface is not uniformly covered by the weft yarns, and a part of the texture points is randomly distributed on the surface of the fabric. It can be an exposed fabric surface morphology.

In the present invention, the buffing process is carried out under the conditions that the surface touch of the nap due to the cutting of the ultrafine yarn of the weft yarn and a part of the polyamide yarn and the bulge and drape property due to the effect of the warp yarn are obtained. is there.

After the buffing process, dyeing for imparting a different color effect to the cloth surface is carried out by two-bath dyeing, and the cloth is set to a predetermined width and length by the finishing set, and the woven fabric having fluff on the surface of the present invention is obtained. Obtainable.
