Description of the Related Art Conventionally, hook-and-loop fasteners have been utilized in various fields such as living materials such as clothes, shoes and curtains, earth and wood for ground modification, and industrial materials for simple packaging because of their convenience. Have been. A hook-and-loop fastener is basically composed of a hook (male material) and a loop (female material). The hook and loop shapes and materials are studied and devised according to the application and conditions to be used. I have. However, much of it is about hooks and very little about loops. A typical example of the loop is a knitted loop, and a part of a woven fabric is fluffed. All of these were poor in engagement strength, and were also poor in durability of engagement strength.

The engagement strength, the durability, and the pull-out resistance were small. In addition, in the field of disposables, there are also those using short-fiber non-woven fabrics, but the strength of the loop or the pull-out resistance is weak, which is unsuitable for repeated use.
In order to solve these drawbacks, there have been some efforts to increase the thickness of the fiber or to solidify it with an adhesive or low-melting fiber, but all of them have a hard texture, which limits the applications that can be used. There was a problem.

ましい。Hereinafter, the present invention will be described in detail. The surface fastener female material of the present invention is one in which a number of loops are formed by needle punching on the surface of a spunbonded nonwoven fabric made of synthetic fibers and fixed by heat fusion of a low melting point component. As the material, polyethylene terephthalate, polyester fibers such as polybutylene terephthalate, or copolymerized polyester fibers containing isophthalic acid, or other copolymerized polyester fibers, or fibers composed of denatured products such as polyethylene terephthalate,
Alternatively, aliphatic or aromatic polyamide fibers are exemplified. These fibers preferably have high strength and low elongation.

５重量％含ませ、加熱することによって行なわれる。A loop formed by a needle punch is formed on at least one surface of the spunbonded nonwoven fabric, and the loop engages with a male hook as a female material. The loop is firmly fixed to the base of the female material of the surface fastener. It must be. Then, the low-melting component is fixed to the spunbonded nonwoven fabric by 1 to 2 times.
It is performed by adding 5% by weight and heating.

好ましくない。If the amount of the low melting point component is too large or too small with respect to the spunbonded nonwoven fabric, the desired product cannot be obtained. When the applied amount of the low melting point component is less than 1% by weight, the fibers of the spunbond nonwoven fabric of the female fastener are adhered to the surface of the male fastener when the adhesive is engaged with the male fastener and then peeled off. Further, the strength of the spunbonded nonwoven fabric constituting the female member of the hook-and-loop fastener is also reduced, so that the engagement strength is remarkably reduced and repeated use is not possible. On the other hand, if the content exceeds 25% by weight, the loop is firmly fixed while lying down, and the surface of the spunbonded nonwoven fabric is hardened, so that the male fastener member hardly penetrates the female fastener member, so that the engagement strength is significantly reduced. It is not preferable.

る。The shape of the low melting point component used may be any of a fiber sheet, a film and a powder. The material of the low melting point component is preferably mainly polyethylene, polypropylene or the like. When the spunbonded nonwoven fabric is made of polyethylene terephthalate, examples thereof include polyester containing polybutylene terephthalate or isophthalic acid.

ているからである。[0013] Among the nonwoven fabrics, spunbonded nonwoven fabrics are preferred for the following reasons. That is, since the spunbonded nonwoven fabric is composed of filaments, so-called filaments, as compared with other nonwoven fabrics, especially short fiber nonwoven fabrics, it is excellent in tensile strength and tear strength, and is suitable as a female material for hook-and-loop fastener.

0 g / mTwo Is preferred. 40g / m Two Less than fiber
The amount is small, and the engagement strength is reduced, which is not preferable. 30
0 g / mTwo Beyond that, it becomes hard and becomes familiar with irregularities.

【００１５】該スパンボンド不織布の少なくとも一面に
多数のループが存在するが、このループはニードルパン
チによるループが好ましい。ループの大きさ、形態が安
定してばらつきが少ないためである。[0015] A large number of loops are present on at least one surface of the spunbonded nonwoven fabric, and these loops are preferably loops formed by needle punching. This is because the size and form of the loop are stable and have little variation.

ない。The loop existing on the surface of the spunbonded nonwoven fabric is fixed by heating the low melting point component.
The height of the loop is preferably 0.3 to 7 mm. When the height is less than 0.3 mm, the engagement strength is insufficient, and on the other hand, 7 mm
When the length exceeds the above range, the loop is easily broken, the strength of the spunbonded nonwoven fabric decreases, and the male fastener does not reach the surface of the female fastener.

用途が限定され好ましくない。The filaments of the synthetic fibers constituting the spunbonded nonwoven fabric preferably have a thickness of 1 to 20 denier. If it is less than 1 denier, the strength of the loop becomes small due to insufficient strength of the single yarn,
At the time of engagement, it is easily cut with a male material, and is not preferable because it does not serve as a fastener. On the other hand, if it exceeds 20 denier, the fibers are not easily entangled during needle punching, the strength as a nonwoven fabric is not sufficiently obtained, and the tingling feeling is strong, and the application is limited, which is not preferable.

This is for increasing the engagement strength and for increasing the durability of the engagement strength.

A spunbond nonwoven fabric made of synthetic fibers is produced by a conventional method. Next, before or after the needle punching, a low melting point component is applied to the spunbonded nonwoven fabric. When the shape of the low melting point component is a fiber sheet, a synthetic fiber is spun,
When forming the sheet into a spunbonded nonwoven fabric, the low-melting-point component is applied to the spunbonded nonwoven fabric after the spunbonded nonwoven fabric is formed and before the needle punch is performed or after the needle punch is performed.

When the low melting point component is a powder, it is applied by a method such as electrostatic spraying or vibration spraying before and after needle punching.

Or it is given to the inner layer. In the case of the latter, a material in which a low melting point component is sandwiched between two spunbonded nonwoven fabrics is exemplified. When producing a spunbonded nonwoven fabric, a fiber-opening improver, an antioxidant, a stabilizer, and an ultraviolet absorber are appropriately applied during spinning and before and after web formation.

If it exceeds 2, (the thickness of the needle becomes thin), the needle is easily broken at the time of processing and the productivity is lowered, and the broken needle is mixed into the spunbonded nonwoven fabric, which is not preferable from the viewpoint of safety. If the needle number is less than 30 (thickness of the needle becomes thicker), friction with the fiber increases during processing, the fiber is easily cut, and the strength (tensile strength) of the spunbonded nonwoven fabric decreases, which is not preferable. . Needle punching is performed on one or both sides as necessary to form a loop.

NO11 had too much low-melting-point component, had a poor feel, and had a low engagement strength. Nos. 12 and 13 were all bad except for type familiarity because there was no loop. NO14 ~
20 were all excellent in overall evaluation.
