The flat fastener is usually composed of a female member having an engaging member of a ring shape or an arch shape, and a male member having a key portion or a mushroom-shaped hook portion. The flat fastener is used for engaging the product to which the flat fastener is attached, and is widely used as a buckle for clothes, shoes, leather bags, gloves, etc., because it is easy to be attached and fixed (for example, see Patent Document 1) Patent Document 2 and Patent Document 3).

However, the flat fastener has such a problem that the opposite side of the engaging function has a large peeling sound when the female member of the flat fastener is separated from the male member. Furthermore, the base fabric portion or the hook portion of the flat fastener is hard, so that it is difficult to stab the clothing or the like, or the skin may be damaged.

As an improvement of these problems, the industry has proposed one A cloth having a superfine fiber as a female member and a vertical cloth as a male member can suppress the peeling sound when the female member is separated from the male member, and is a soft flat fastener (see, for example, Patent Document 4).

However, the above problems have not yet reached a point where they are sufficiently solved, and there is room for improvement in the effects of repeated fixing and detachment and washing and the like on the durability of the splicing property.

Next, the fabric A can be obtained by forming a resin layer as described above.

Since the fabric A thus obtained has a resin layer on the side opposite to the joint surface, the rigidity is high and the durability of the joint force is improved. Further, in the case of the filament yarn A containing ultrafine fibers, it can be suitably used as a female member of a flat fastener.

Here, in the above fabric A, it is preferable that the filament yarn (nanofiber) is exposed on at least one of the front surface and the back surface.

Further, the vertical length of the vertical yarn is preferably in the range of 0.1 to 10 mm. If the length of the vertical hair is less than 0.1 mm, the length of the vertical hair is too small, and when the vertical felt 帛B is used as a male member and the female member is engaged with the female member, strong adhesion cannot be obtained. On the other hand, if the length of the vertical hair is more than 10 mm, the vertical hair state is difficult to maintain, and when the vertical felt 帛B is used as a male member and the female member is engaged with each other, the strong snap-fit property cannot be obtained.

Sexuality.

The vertical yarn density can be measured by the following method. That is, the surface of the vertical felt (200 times magnification) was photographed using a microscope (type: VHX-900) manufactured by KEYENCE CORPORATION, and the count of the vertical yarn of 1 cm ² (1 cm x 1 cm) per unit area was measured and calculated by the following formula.

Vertical yarn density (dtex/cm ² ) = single fiber fineness (dtex) x vertical yarn count (branch / cm ² )

The type of the fiber forming the vertical yarn is not particularly limited, and may be cotton, wool, hemp, mucus fiber, polyester fiber, polyether ester fiber, acrylic fiber, nylon fiber, polyolefin fiber, cellulose acetate.

The loop structure of the protruding fluff, the columnar tricot woven fluff, the double raschel fluff, and the like, and the method of shearing the loop. The columnar tricot weave can be obtained by forming a loop of a columnar tricot-woven pile by using a hair raising machine to form a loop.

On the other hand, in order to obtain the woven fabric B having the woven fabric structure, it is possible to woven and weave the warp pile fabric or the weft pile fabric. The loop pile is cut, or woven into a pile fabric, and the center of the pile yarn is cut.

For the batt cloth B thus obtained, it is possible to additionally apply a conventional dyeing process, a raising process, a water repellent process, a water absorbing process, a surface polishing process, and further, to impart ultraviolet shielding or a power-generating agent, an antibacterial agent, and a deodorant.
