  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 and Patent Document 5).

  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 hook-and-loop fastener of the present invention, the fabric A serving as a female material can be manufactured, for example, by the following manufacturing method. First, a sea-island composite fiber (fiber for nanofiber) formed by a sea component and an island component having a diameter of 1000 nm or less is prepared. As such a sea-island type composite fiber, a sea-island type composite fiber multifilament (100 to 1500 islands) disclosed in Japanese Patent Application Laid-Open No. 2007-2364 is preferably used.

  The sea-island composite fiber composed of the sea component polymer and the island component polymer preferably has a sea component melt viscosity higher than that of the island component polymer during melt spinning. Moreover, it is preferable to make the diameter of an island component into the range of 10-1000 nm. At this time, if the diameter is not a perfect circle, the diameter of the circumscribed circle is obtained. 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. The obtained undrawn yarn is made into a composite fiber having desired strength, elongation, and heat shrinkage properties through a separate drawing process, or is taken up by a roller at a constant speed without being wound once, and subsequently drawn.

It is preferable to be within the range of ˜100 dtex).

  Then, the fabric A is knitted or woven using such a sea-island type composite fiber multifilament alone or with other yarn such as an elastic fiber yarn having a single fiber diameter larger than 1000 nm as necessary. At that time, the structure of the fabric A is not particularly limited, and may be a woven fabric, a knitted fabric, or a nonwoven fabric obtained by a usual method. Of these, a woven fabric or a knitted fabric is preferable, and a knitted fabric is particularly preferable. In the case of a knitted fabric, it is preferable that the raised yarn of the male material can be firmly engaged by the loop of the knitted fabric. In particular, it is preferable that the needle surface of the knitted fabric is used as a surface that engages with the male material because excellent engagement is obtained.

  Here, the woven structure of the woven fabric is a three-fold structure such as plain weave, oblique weave, satin weave, etc. Examples include vertical pile weaves such as fresh velvet, towels and velours, bevel pile weaves such as benjin, weft velvet, velvet and call heaven. In addition, the textile fabric which has these woven structures can be woven by a normal method using normal looms, such as a rapier loom and an air jet loom. The number of layers is not particularly limited and may be a single layer or a woven fabric having a multilayer structure of two or more layers.

The number of layers is not particularly limited and may be a single layer or a knitted fabric having a multilayer structure of two or more layers.

  Next, the fabric is subjected to an alkaline aqueous solution treatment, and sea components of the sea-island composite fiber are dissolved and removed with an alkaline aqueous solution, whereby the sea-island composite fiber multifilament is made into a filament yarn having a single fiber diameter of 10 to 1000 nm. At that time, the alkaline aqueous solution treatment may be performed at a temperature of 55 to 70 ° C. using a NaOH aqueous solution having a concentration of 1 to 4%.

Next, the fabric A can be obtained by forming the resin layer as described above.
Since the fabric A thus obtained has a resin layer on the side surface opposite to the bonding surface, the rigidity is high and the durability of the bonding force is improved. Moreover, when the said filament yarn A which is a super extra fine fiber is contained, it can use suitably as a female material of a hook_and_loop | surface fastener.

  Here, in the fabric A, the filament yarn (nanofiber) is preferably exposed on at least one of the front surface and the back surface. When the filament yarn is not exposed on either the front surface or the back surface, there is a possibility that the male raised yarn cannot be engaged.

  In the present invention, the female material may be composed of the fabric A only by appropriately cutting the fabric A, or may be sewn so that the periphery of the fabric A will not fray. No problem. When cutting the fabric A, since the fabric A has a resin layer and high rigidity, it has an excellent effect that wrinkles are hardly generated in the cut portion.

  Next, the surface fastener of the present invention includes a raised fabric B that is a male material. The napped fabric B has a ground tissue portion having a knitted fabric structure composed of organic fiber yarns, and is knitted or woven into the ground tissue portion, and extends from the ground texture portion to at least one surface side thereof. And a raised portion composed of a plurality of raised yarns. The napped yarn may be a loop pile, but is preferably a cut pile in order to obtain strong engagement.

  The napped yarn preferably has a single fiber fineness of 0.5 dtex or more (preferably 0.5 to 5.0 dtex). If the single fiber fineness is less than 0.5 dtex, it is difficult to maintain a raised state, and there is a possibility that firm engagement cannot be obtained when the raised fabric B is used as a male material and engaged with a female material. is there.

  Moreover, it is preferable that the raised length of the raised yarn is in the range of 0.1 to 10 mm. If the napped length is less than 0.1 mm, the napped length is too small, and there is a possibility that firm engagement cannot be obtained when the napped fabric B is used as a male material and engaged with a female material. On the contrary, if the length of the raised hair is larger than 10 mm, it is difficult to keep the raised state, and there is a possibility that firm engagement cannot be obtained when the raised fabric B is used as a male material and engaged with a female material. is there. In the present invention, the nap length is the height of L shown in FIG.

The napped yarn density of the napped portion formed by the napped yarn is preferably 3000 dtex / cm ² or more (preferably 5000 to 100000 dtex / cm ² ). When the napped yarn density is less than 3000 dtex / cm ² , the napped yarn is liable to fall down, so that it is difficult to maintain the napped state, and when the napped fabric B is used as a male material and is engaged with a female material, it is strong. 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. Calculate by the formula.
Napped yarn density (dtex / cm ² ) = single fiber fineness (dtex) × number of napped yarn (lines / cm ² )

  The type of fiber forming the napped yarn is not particularly limited. Cotton, wool, hemp, viscose rayon fiber, polyester fiber, polyetherester fiber, acrylic fiber, nylon fiber, polyolefin fiber, cellulose acetate fiber, aramid fiber Ordinary fibers such as Of these, polyester fibers made of polyester as described above are particularly preferable in terms of recyclability and rigidity.

  The shape of the raised yarn may be a non-crimped raised yarn, a false twist crimping method, a mechanical crimping method, or a crimped standing obtained by heat-treating a Cybyside type latent crimpable composite fiber. A wool yarn may be used and is not particularly limited, but a non-crimped yarn is preferable in order to obtain strong engagement.

  There are no particular limitations on the single fiber cross-sectional shape of the napped yarn, and it may be a regular circular cross section, a triangular, flat, constricted flat, cross, hexagonal, or hollow cross section.

  In the above-mentioned raised fabric B, the ground texture portion is composed of organic fiber yarns and has a knitted texture. As a fiber which comprises this organic fiber yarn, the thing similar to the fiber illustrated as an example for the above-mentioned napped yarn may be sufficient. In particular, polyester fiber is preferable in terms of recyclability.

  Although the form of the organic fiber yarn constituting the ground tissue part is not particularly limited, it is preferably a long fiber (multifilament yarn). The single fiber fineness and the total fineness of the organic fiber yarn are preferably a single fiber fineness of 0.5 to 5.0 dtex and a total fineness of 30 to 300 dtex without impairing the texture of the fabric. The cross-sectional shape of the single fiber is not limited, and may be a triangular, flat, constricted flat, cross, hexagonal, or hollow cross-sectional shape in addition to a normal circular cross section. Furthermore, such organic fiber yarns include false twisted crimped yarns, composite yarns obtained by subjecting two or more types of constituent yarns to air-mixing processing or composite false twisting processing, an elastic yarn in the core portion, and a non-woven fabric in the sheath portion.

It is preferable to cut and / or cut the tip of the loop pile as necessary, after knitting and weaving a normal raised fabric (loop pile fabric) using the yarn.

  Here, in the case of obtaining a napped fabric having a knitted structure in the ground structure part, the ground structure is knitted, and a loop pile structure such as a sinker pile, a pole tricot pile, and a double raschel pile extending thereon is formed. 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.

Can be added. When cutting the fabric B, since the fabric B has a resin layer and has high rigidity, it has an excellent effect that wrinkles are hardly generated in the cut portion.

  In the raised fabric B, it is preferable that the raised length of the raised portion is in the range of 0.1 to 3.0 mm.

  In the raised fabric B, it is preferable that the elongation in either the vertical or horizontal direction is in the range of 1 to 20%.

  Moreover, in the said raised fabric B, it is preferable that the bending softness of either one of a length or a width direction is 25 mm or more (preferably 25-80 mm).

Has engagement. At that time, the tensile shear strength defined below is 50 cN / cm ² or more (preferably 50 to 300 cN / cm ² ) before washing (F0) and 10 times after washing (F10), and after 2000 times repeated desorption. (F2000) is 40 cN / cm ² or more (preferably 40 to 300 cN / cm ² ).

For each of the fabric A and the raised fabric B, two samples cut to a length of 12 cm in the horizontal direction and a width of 3 cm are overlapped with the entire width in parallel to the length direction by 5 cm in the length direction, and then the pressure roller After two reciprocations were applied while applying a load of 9.8 N / cm ² (1 kg / cm ² ), the two samples were attached to each other, and then mounted on a tensile tester, with a tensile speed of 300 mm / min and an initial load of 19.6 cN ( 0.2 kg), the sample is pulled in parallel with the length direction of the sample, and the maximum tensile shear strength until the two samples are separated is measured. Then, the tensile shear strength per unit area is obtained by the following formula, and n number The average value at 5 is calculated.
