Hook and loop fastener and textile products

Abstract

The present invention addresses the problem of providing a hook and loop fastener that not only has excellent engaging properties but is also flexible, generates little ripping noise when the male part and female part are separated, is excellent for sewing to fabric or the like, and is very durable, and a textile product comprising the hook and loop fastener. A hook and loop fastener comprises a fabric A that has a resin layer and a napped fabric B that has a resin layer containing a napped portion and a ground structure portion.

1 . A hook and loop fastener composed of a fabric A and a napped fabric B containing a napped portion and a ground structure portion, wherein both the fabric A and the napped fabric B have resin layers. 
     
     
         2 . The hook and loop fastener according to  claim 1 , wherein the resin layer is a resin coating layer or laminated layer. 
     
     
         3 . The hook and loop fastener according to  claim 1 , wherein the fabric A has a knitted fabric texture. 
     
     
         4 . The hook and loop fastener according to  claim 1 , wherein the fabric A includes filament yarn having a monofilament diameter of no greater than 1000 nm. 
     
     
         5 . The hook and loop fastener according to  claim 4 , wherein the filament yarn is made of polyester and consists of multifilaments with a number of filaments of 1000 or more. 
     
     
         6 . The hook and loop fastener according to  claim 4 , wherein in the fabric A, the filament yarn is exposed on the fabric surface in the form of loops. 
     
     
         7 . The hook and loop fastener according to  claim 1 , wherein the thickness of the fabric A is in the range of 0.3 to 3.0 mm. 
     
     
         8 . The hook and loop fastener according to  claim 1 , wherein the elongation percentage in either the warp direction or the weft direction of the fabric A is in the range of 1 to 20%. 
     
     
         9 . The hook and loop fastener according to  claim 1 , wherein the bending resistance in either the warp direction or the weft direction of the fabric A is 25 mm or greater. 
     
     
         10 . The hook and loop fastener according to  claim 1 , wherein in the napped fabric B, the napped portion is made of polyester and consists of napped yarn with single fiber fineness of 2.5 dtex or greater. 
     
     
         11 . The hook and loop fastener according to  claim 1 , wherein the napping length of the napped portion in the napped fabric B is in the range of 0.1 to 3.0 mm. 
     
     
         12 . The hook and loop fastener according to  claim 1 , wherein the elongation percentage in either the warp direction or the weft direction of the napped fabric B is in the range of 1 to 20%. 
     
     
         13 . The hook and loop fastener according to  claim 1 , wherein the bending resistance in either the warp direction or the weft direction of the fabric B is 25 mm or greater. 
     
     
         14 . The hook and loop fastener according to  claim 1 , wherein the tensile shear strength according to the following definition is 50 cN/cm 2  or greater:
 For both the fabric A and the napped fabric B, two samples cut to 12 cm length and 3 cm width in the horizontal direction are layered 5 cm in the lengthwise direction and across the full width parallel in the lengthwise direction, the two samples are bonded by 2 passes under a load of 9.8 N/cm 2  (1 kg/cm 2 ) with a contact pressure roller and then loaded into a tensile tester and subjected to tension parallel to the lengthwise direction of the sample with a pull rate of 300 mm/min and an initial load of 19.6 cN (0.2 kg), and after measuring the maximum tensile shear strength until separation of the two samples, the tensile shear strength per unit area is calculated by the following formula, and the average value is calculated for n=5:
     F 1= S /( L×W ) 
   F1 is the tensile shear strength (cN/cm 2 ), S is the maximum tensile shear load (cN), L is the layering length (cm) and W is the sample width (cm).   
     
     
         15 . Textile products selected from the group consisting of nursing clothing, medical clothing, sportswear, outer wear, inner wear, pajamas, men's wear, ladies' wear, bathrobe, working clothes, protective wear, combat wear, hunting wear, footwear, bags, caps, gloves, socks, shoes, bedding, support, connecting members, bandages, safety belts, flooring materials, covers, cushions, base fabrics, supporters, belly bands, aprons, body covers, capes, skin care instruments and cosmetic tools, that comprise a hook and loop fastener according to  claim 1 . 
     
     
         16 . The hook and loop fastener according to  claim 2 , wherein the fabric A has a knitted fabric texture.
