Woven Fabric and Articles Made by Using the Same

Abstract

A woven fabric made by using fiber-reinforced thermoplastic resin strands produced by stretching a bundle of sheath-core type conjugated filaments at a temperature of the melting point of the sheath component or above but below the melting point of the core component while fusing the sheath component, wherein the sheath-core type conjugated fiber is a nontwist straight one whose sheath component has a melting point lower than that of the core component by 20° C. or above; and articles made by using the fabric.

1 . A woven fabric obtained from a fiber-reinforced thermoplastic resin linear material formed by drawing sized sheath-core type bicomponent-spun fibers at a temperature that is equivalent to, or higher than, the melting point of a sheath component but lower than the melting point of a core component to melt-fuse sheath components, the fiber-reinforced thermoplastic resin linear material having a cross-sectional structure in which the core components are arranged in a state of islands in a sea formed by the melt-fusion of the sheath components, said sheath-core type bicomponent-spun fiber being a straight non-twisted sheath-core type bicomponent-spun fiber that has the sheath component formed from a thermoplastic resin having a lower melting point than the core component by 20° C. or more. 
   
   
       2 . The woven fabric of  claim 1 , which has a tenacity contribution, represented by the following expression, of 80% or more,
   Tenacity contribution(%)=( B/A )×100  (1)   
     wherein A is a tensile tenacity (N/3 cm) calculated from the fiber-reinforced thermoplastic resin linear material, the tensile tenacity being calculated according the expression of tenacity (N) of said linear material x filament count of said linear material/2.54 cm×3 cm, and B is a tensile tenacity (N/3 cm) of the woven fabric. 
   
   
       3 . The woven fabric of  claim 1 , which has a basis weight of 50 to 500 g/m 2 . 
   
   
       4 . The woven fabric of  claim 1 , wherein the thermoplastic resin is a polyolefin. 
   
   
       5 . The woven fabric finished article obtained by working on the woven fabric recited in  claim 1 . 
   
   
       6 . The woven fabric finished article of  claim 5 , wherein the working is hot press treatment. 
   
   
       7 . The woven fabric finished article of  claim 5 , wherein the working is a treatment to newly form a thermoplastic resin coating layer on at least one surface. 
   
   
       8 . A waterproof sheet-shaped material comprising the woven fabric recited in  claim 1 , which is measured for a height of water from an end face after allowed to stand for 10 minutes according to a Byrek method defined in JIS L 1907 to show 10 mm or less. 
   
   
       9 . The waterproof sheet-shaped material comprising the woven fabric finished article of  claim 5 , which is measured for a height of water from an end face after allowed to stand for 10 minutes according to a Byrek method defined in JIS L 1907, to show 10 mm or less.
