Description

  The present invention is a hook-and-loop fastener composed of a female material and a male material, which not only has excellent engagement, but is flexible and does not generate much peeling noise when separating the female material and the male material. In addition, the present invention relates to a hook-and-loop fastener excellent in stitchability to fabric and the like and excellent in durability, and a textile product including the hook-and-loop fastener.

  A hook-and-loop fastener is usually composed of a female material having a loop-shaped or arch-shaped engaging element and a male material having a hook-shaped or mushroom-shaped hook portion. A hook-and-loop fastener engages a product with a hook-and-loop fastener, and is easy to attach and detach. Therefore, the hook-and-loop fastener is generally widely used as a fastener for clothes, shoes, bags, gloves, and the like (for example, Patent Document 1). , Patent Document 2 and Patent Document 3).

  However, the hook-and-loop fastener has an engagement function as described above, but there is a problem that a large peeling noise is generated when the female material and the male material of the hook-and-loop fastener are separated. Furthermore, since the base fabric part and the hook part of the hook-and-loop fastener are hard, there is a problem that it is difficult to sew to clothes or the like, and the skin is damaged.

  As an improvement of these problems, a flexible surface fastener has been proposed in which a fabric containing ultrafine fibers is used as a female material, and a napped fabric is used as a male material to suppress peeling noise when separating the female material and the male material. (For example, refer to Patent Document 4).

  However, the problem has not yet been solved sufficiently, and there is room for improvement in the durability of engagement by repeated desorption and washing.

In the sea-island composite fiber, the sea-island composite weight ratio (sea: island) is preferably in the range of 40:60 to 5:95, and particularly preferably in the range of 30:70 to 10:90.

  Such sea-island type composite fiber multifilament can be easily produced by, for example, the following method. That is, melt spinning is performed using the sea component polymer and the island component polymer. As the spinneret used for melt spinning, any one such as a hollow pin group for forming an island component or a group having a fine hole group can be used. The discharged sea-island type cross-section composite fiber multifilament is solidified by cooling air, preferably melt-spun at 400 to 6000 m / min, and wound up.

There is a possibility that the engagement cannot be obtained.

Such napped yarn density can be measured by the following method. That is, using a microscope (model: VHX-900) manufactured by Keyence Corporation, the surface of the napped fabric was photographed (magnification 200 times), and the number of napped yarns per 1 cm ² (1 cm × 1 cm) area was measured. Calculated by the formula.
Napped yarn density (dtex / cm ² ) = single fiber fineness (dtex) × number of napped yarn (lines / cm ² )

A method of shearing the loop pile is used. The pole tricot pile is obtained by forming a pile knitted portion of a tricot knitted structure into a loop pile using a raising machine.

  On the other hand, in the case of obtaining a raised fabric B having a fabric structure in the ground texture portion, weave a warp pile fabric or a weft pile fabric and cut the loop pile or weave a moquette fabric and center the pile yarn. A method of cutting is used.
