Description of the Related Art Generally, a surface fastener is made of a loop type female member and a male member having a hook portion such as a hook type or a mushroom type engaging with the female member. Since the hook-and-loop fastener can be used easily, it can be used to open and close clothing, bags, shoes, daily necessities, etc.
It is used by being installed on the seat cover of a vehicle. In addition, recently, in order to fix and fix a disposable diaper, a hook-and-loop fastener attached to the waist portion of the diaper has been proposed and put into practical use.

る。As described above, the surface fasteners are used in various fields. Generally, the performance required for the surface fasteners is that the peel strength is strong, that is, the male material and the female material are in opposite directions to the fastener surface. And the two members cannot be easily disengaged even when pulled vertically, and the tensile strength is strong, that is, even when the male and female members are pulled horizontally in opposite directions, they can be easily engaged. Mainly mentioned are those that cannot be unraveled, and those whose fastener part does not become bulky, especially those that are thin and flexible when used for clothing, diapers, etc., and so-called disposable diapers, etc. When used for merchandise, it is required that the manufacturing cost be low. To meet these requirements, various surface fasteners have been proposed.

Further, in Japanese Unexamined Patent Publication (Kokai) No. 4-105602, a surface fastener female material having a sufficient engaging force and not being bulky by inserting a multifilament yarn having a large number of loops, coils, etc. on its surface into a cloth by a fluid disturbance treatment. Is described. In addition, JP-A-6-3
No. 3359 discloses a surface fastener female member made of a long-fiber nonwoven fabric having a large number of wrinkles formed on its surface.

スナー雌材は未だ得られていないのである。However, these surface fastener female members have the following disadvantages.
That is, the fastener member disclosed in JP-A-62-38105 has no problem in terms of peeling strength and tensile strength, but it is unavoidable that the manufacturing cost is increased because stitching is performed on the non-woven fabric, which leads to price competition. Not suitable for intense disposable products. Similarly, the female material described in Japanese Patent Laid-Open No. 4-105602 has no problem in peel strength and tensile strength, but since it is necessary to weave one or more specific multifilaments, the manufacturing cost becomes high. On the other hand, the long-fiber non-woven fabric disclosed in JP-A-6-33359 can be manufactured at low cost and is suitable for disposable diapers and the like, but has a weak engagement force with a male material, peel strength, and tensile strength. In terms of points, I'm never satisfied. That is, a female member for a surface fastener that satisfies all the above-mentioned required performances and is economically advantageous has not yet been obtained.

ことを見い出し、本願発明に至った。Therefore, the present inventors have solved the disadvantages found in conventional female members for surface fasteners, and have reduced the cost of a female member exhibiting excellent peeling strength and tensile strength even when engaged with any male member. As a result of diligent examination to be able to provide,
When a fibrous web is laminated on a woven or knitted fabric having a relatively coarse mesh and entangled and integrated, and a part of the fibrous web is penetrated to form a loop on the surface of the knitted or woven fabric, a composite sheet is obtained. The inventors have found that they are suitable for female fasteners and have reached the present invention.

面ファスナー雌材である。The present invention is a composite sheet in which a woven or knitted fabric and a fibrous web are entangled and integrated with each other, and some of the fibers of the web penetrate the woven or knitted fabric to form a woven fabric. Alternatively, the surface fastener female member is characterized in that 2 to 20 loops are formed per cm 2 on the surface of the knitted fabric.

る。In the present invention, a woven or knitted fabric (hereinafter,
The woven and knitted fabrics) not only contribute to the improvement of the dimensional stability of the entire female material by being combined and integrated with the fibrous web to contribute to the improvement of the dimensional stability of the entire female material. Since it engages with the hook part of the
It is an element that affects the tensile strength. Therefore, a knitted fabric having a bulge in the thickness direction is more likely to engage with the hook portion than a woven fabric having a planar structure, and thus the knitted fabric can be more preferably used in the present invention.

糸条を選択すれば良い。The yarns constituting the woven or knitted fabric may be any of monofilament, multifilament, spun yarn, split yarn and the like. However, in consideration of the ease of engagement between the woven and knitted material and the male material, a multifilament composed of a plurality of fibers or a woven or knitted material formed by spun yarn is more preferable than the monofilament. Further, the thinner the yarns constituting the woven or knitted fabric, the softer the final female material becomes, and the smaller the thickness. However, when the yarns are too thin, the yarns are integrated when they are integrated with the short fiber web by needle punching or the like. It should be noted that the strips are easily cut and cause fuzz. On the other hand, if the yarn becomes thicker, it will not fluff, but it will be less flexible and thicker. Since the flexibility and thickness are affected by the raw material of the yarn and the density (coarseness) of the woven or knitted fabric, the yarn having an appropriate thickness may be selected in relation to them.

Among them, a coarse woven or knitted fabric composed of a monofilament or a multifilament obtained by melt-spinning nylon or polyester can be obtained at a low price, and thus is suitable for a female surface fastener used in disposable products such as diapers. is there.

ァスナー全体の係合力が低下し好ましくない。The female member of the surface fastener of the present invention is characterized in that the woven and knitted fabric and the fibrous web are compounded and integrated, and a loop is formed on the surface of the woven and knitted fabric by penetrating a part of the fibrous web. This loop serves as a portion that engages with the hook portion of the male material, but as described above, the female material of the surface fastener of the present invention is not only the loop but also a part of the yarns constituting the woven or knitted fabric. It is characterized in that it engages with the male material, and when both are involved in the engagement, they exhibit an excellent engaging force that cannot be obtained by themselves. Therefore, the number of loops is
The maximum peel strength and tensile strength must be selected within a range that does not prevent the engagement between the male material and the woven or knitted material. The loop is formed in a state in which a plurality of fibers in the short fiber web are bundled, and in the present invention, it is desirable that 2 to 20 such bundled loops are formed per cm 2 . If the number is less than 2, the male material will exclusively engage with the yarns in the woven or knitted fabric, but if the hook portion only engages with the woven or knitted fabric, the yarns constituting the woven or knitted fabric will be pulled when the male material is peeled off. There is such a problem. On the other hand, if the number of hooks exceeds 20, the hooks of the male member will engage exclusively with the fibers in the loop, making it difficult to engage with the yarns that make up the woven or knitted fabric, and rather reduce the engaging force of the entire fastener, which is not preferable.

る必要がある。Further, in the present invention, it is important that the base portion of the loop formed on the surface of the woven or knitted fabric is strongly held by the woven or knitted fabric and the short fiber web. This is because if the base of the loop is not held, the fibers forming the loop fall off due to repeated engagement and peeling, so-called "cotton loss" occurs, which causes fuzzing of the female material. Further, in a state where “cotton omission” is likely to occur, when the male material is separated from the female material, the fibers that have come out of the female material are easily entangled with the hook portion of the male material. It is empirically well known that engagement of a male material with a female material is significantly hindered when foreign matter such as fibers adheres to the hook portion. Therefore, especially when repeatedly engaging and releasing, "cotton loss" leads to a reduction in the engaging force of the entire fastener, and this must be avoided as much as possible.

という利点もある。Specifically, as a method of strongly holding the base portion of the loop to the woven and knitted fabric and the short fiber web, the short fiber web is preliminarily mixed with a heat-adhesive fiber or a low melting point binder, and after the loop formation, heat treatment is performed. Examples of the method include applying and melting and softening the heat-adhesive fiber to heat-bond the root portion of the loop to the woven or knitted fabric and the short fiber web. At this time, it is necessary to perform the heat treatment so that the shape of the loop is not collapsed as much as possible, and a specifically preferable heat treatment method is a method of passing through a hot air penetration type dryer. Moreover, since the base of the loop is heat-bonded by the heat treatment and the constituent fibers of the short fiber web are bonded together, there is also an advantage that the morphological stability and dimensional stability of the entire female material are improved.

ール未満とすることが望ましい。The short fiber web used in the present invention must be capable of partially penetrating the woven or knitted fabric to form loops on the woven or knitted fabric surface. Specifically, a card web composed of short fibers having a fiber length of 38 to 76 mm and a fineness of 1.5 to 10 denier can be preferably used.
If the fiber length is less than 38 mm, cotton loss is likely to occur in the loop portion, which causes fluffing, and further, there is a problem that the engaging force is reduced when repeatedly engaging and separating. If it exceeds 76 mm, the card passing property will be deteriorated. When the fineness is less than 1.5 denier, the loop formed on the surface of the woven or knitted fabric is easily cut, which causes fluffing and causes a reduction in engaging force when repeatedly engaged. Further, in the web having the same weight, the number of constituent fibers per unit volume decreases as the fineness increases, so that the number of fibers forming one loop and the number of formed loops also decrease. This means that the rate at which the hook portion of the male material engages with the loop decreases and the rate at which it engages with the yarns constituting the woven or knitted material increases. Therefore, if the fineness becomes too large, the male material engages exclusively with the woven or knitted fabric, causing the above-mentioned problem of tightness of the yarn. In order to avoid such problems, it is desirable that the fineness is less than 10 denier.

不都合も生じる。The basis weight of the fibrous web is 10 to 100 g / m 2.
Within the range, it can be arbitrarily selected according to the application and the like. When the basis weight of the fibrous web is less than 10 g / m 2 , loops are not sufficiently formed and the male hook portion engages exclusively with the woven or knitted fabric, so that the yarns constituting the woven or knitted fabric are tightly pulled as described above. There is a problem that it will end up. Again 10
If it exceeds 0 g / m 2 , the formation of the loop becomes too dense and the male material and the female material engage only in the loop, and the woven or knitted fabric cannot participate in the engagement, so that the engaging force is rather small. In addition to the problem, the resulting female material becomes very bulky, lacks flexibility, and is not practical.

One or more selected from synthetic fibers such as polypropylene, polyethylene and acrylic can be used. Further, as described above, in order to heat-bond the base of the loop formed on the surface of the woven or knitted fabric to the woven or knitted fabric and the short fiber web by heat treatment, the heat-adhesive fibers occupy a part of the fibers constituting the fibrous web. Can be At this time, the proportion of the heat-adhesive fibers is preferably 50% by weight or more, and all the heat-adhesive fibers may be used. Examples of the heat-bondable fibers that can be used here include single fibers made of polyethylene, polypropylene, and polyester, or composite fibers in which the low melting point component occupies a part or the whole of the fiber surface, for example, a sheath / core of polyethylene / Examples thereof include core-sheath type composite fibers such as polyester and polypropylene / polyester. Of course, a heat-bonding component other than the heat-bondable fiber, such as a low-melting-point binder, can be mixed in advance with the fibrous web, in which case the heat-bondable fiber is unnecessary.

ため好ましくない。As a means for integrating the woven and knitted fabric and the fibrous web and forming a loop on the surface of the woven and knitted fabric by penetrating a part of the fibrous web, needle punching is performed by using a needle having a fiber ejecting function. Most preferred. Here, it should be noted that when needle-punching, the number of needles per cm 2 and the number of needles formed on the surface of the woven or knitted fabric should be 1
The number of loops per cm 2 does not always match. Specifically, by performing needle punching with 10 to 100 needles / cm 2 , more preferably 30 to 70 needles / cm 2 , 2 to 20 loops are formed within the above range, that is, per 1 cm 2. be able to. With 10 fibers / cm 2 , the number of loops formed is too small and the woven / knitted fabric and the fibrous web are insufficiently integrated. 10
If it exceeds 0 / cm 2 , not only the formation of loops becomes too dense, but also the yarns constituting the woven or knitted fabric are damaged. The needle depth when performing needle punching is preferably 5 to 20 mm. 5m
If it is less than m, a loop cannot be formed on the surface of the woven or knitted material, and if it exceeds 20 mm, the height of the formed loop becomes high, so that the portion held by the woven or knitted material or the short fiber web is shortened accordingly. It is not preferable because the cotton is easily removed.
