Pile Fabric And Method For Producing The Same

Abstract

A pile fabric having a ground structure portion having a knitted or woven structure comprising organic fiber yarns and a cut pile portion comprising cut piles knitted or woven in said ground structure and having a single fiber fineness of 0.1 to 2.0 dtex is woven or knitted, ant then subjected to a thermal treatment to thermally shrink the above-mentioned cut piles to obtain the pile fabric in which the cut pile density of the cut pile portion is in a range of 40,000 to 300,000 dtex/cm 2 and the cut pile length of the cut piles is in a range of 0.20 to 2.00 mm. If necessary, said pile fabric is used to obtain a vehicle interior material.

1 . A pile fabric having a ground structure portion having a knitted or woven structure comprising organic fiber yarns and a cut pile portion comprising cut piles knitted or woven in said ground structure portion, characterized in that the cut pile density of the above-mentioned cut pile portion is 40,000 to 300,000 dtex/cm 2 , and the single fiber fineness and cut pile length of the cut piles are in the ranges of 0.1 to 2.0 dtex and 0.20 to 2.00 mm, respectively. 
 Therein, the above-mentioned cut pile density is calculated according to the following expression.      Cut pile density[dtex/cm 2 ]=(single fiber fineness of cut piles)[dtex]×(number of cut piles per cm 2 )[cut piles/cm 2]     
   
   
       2 . The pile fabric according to  claim 1 , wherein the single fiber fineness of the cut piles is in a range of 0.1 to 1.2 dtex.  
   
   
       3 . The pile fabric according to  claim 1 , wherein the cut pile length is in a range of 0.20 to 0.80 mm.  
   
   
       4 . The pile fabric according to  claim 1 , wherein the inclination angle of the cut piles is in a range of 70 to 90 degree.  
   
   
       5 . The pile fabric according to  claim 1 , wherein the cut piles are polyester-based fiber yarns.  
   
   
       6 . The pile fabric according to  claim 1 , wherein the organic fiber yarns for forming the ground structure portion are polyester-based fiber yarns.  
   
   
       7 . A method for producing a pile fabric, characterized by weaving or knitting a pile fabric having a ground structure portion having a knitted or woven structure comprising organic fiber yarns and a cut pile portion comprising cut piles knitted or woven in said ground structure portion and having a single fiber fineness of 0.1 to 2.0 dtex and a boiling water shrinkage of not less than 20%, and then applying a thermal treatment to said pile fabric to thermally shrink the above-mentioned cut piles to obtain the pile fabric in which the cut pile density of the cut pile portion is in a range of 40,000 to 300,000 dtex/cm 2  and the cut pile length of the cut piles is in a range of 0.20 to 2.00 mm.  
   
   
       8 . The method for producing the pile fabric according to  claim 7 , wherein yarns having a boiling water shrinkage of not less than 20% are used as the organic fiber yarns for forming the ground structure.  
   
   
       9 . The method for producing the pile fabric according to  claim 7 , wherein false-twisted yarns having a crimp percent of not less than 30% are used as the organic fiber yarns for forming the ground structure.  
   
   
       10 . A vehicle interior material using the pile fabric according to  claim 1 .  
   
   
       11 . A vehicle interior material using the pile fabric according to  claim 2 .  
   
   
       12 . A vehicle interior material using the pile fabric according to  claim 3 .  
   
   
       13 . A vehicle interior material using the pile fabric according to  claim 4 .  
   
   
       14 . A vehicle interior material using the pile fabric according to  claim 5 .  
   
   
       15 . A vehicle interior material using the pile fabric according to  claim 6.
