Recycled fabric structure, knitted vamp cloth and method of manufacturing yarn

Abstract

A recycled fabric structure is provided, which includes a plurality of types of blended yarn arranged by weaving or interlacing. Wherein, each of the types of the blended yarn has a plurality of first fibers and a plurality of second fibers vertically arranged and interloped with each other. The plurality of first fibers accounts for 30% to 50% of the total weight of the blended yarn. The first fiber is a recycled fiber.

What is claimed is: 
     
         1 . A recycled fabric structure, comprising:
 a plurality of types of blended yarn arranged by weaving or knitting, wherein
 each of the types of blended yarn has a plurality of first fibers and a plurality of second fibers vertically arranged and interlooped with each other; 
 the plurality of first fibers accounts for 30% to 50% of a total weight of the blended yarn; 
 the plurality of first fiber is a recycled fiber generated by a machinery fiber opening process applied to a recycled knitted cloth; 
 the blended yarn is an one-ply yarn and has a random wire diameter and a color difference; and 
 a slub part of the one-ply yarn is formed by a part of the plurality of first fibers. 
   
     
     
         2 . The recycled fabric structure of  claim 1 , wherein the part of the plurality of first fibers comprises a nep. 
     
     
         3 . The recycled fabric structure of  claim 2 , wherein the nep of each of the plurality of first fibers has a random size and forms the slub part of the one-ply yarn. 
     
     
         4 . The recycled fabric structure of  claim 1 , wherein the recycled knitted cloth comprises a knitted vamp cloth dyed with at least two colors. 
     
     
         5 . The recycled fabric structure of  claim 1 , wherein the slub of the plurality of first fibers has a random color. 
     
     
         6 . The recycled fabric structure of  claim 1 , wherein the lengths of the plurality of first fibers and the plurality of second fibers are from 30 to 40 mm. 
     
     
         7 . The recycled fabric structure of  claim 1 , wherein the plurality of first fibers comprises at least one type of yarn forming the recycled knitted cloth, and the type of yarn forming the recycled knitted cloth has a denier value from 75D to 600D and a polyfilament yarn number from 24 f to 72 f. 
     
     
         8 . The recycled fabric structure of  claim 1 , wherein a fiber elongation of the blended yarn is a value from 10% to 25%. 
     
     
         9 . The recycled fabric structure of  claim 1 , wherein a fiber strength of the blended yarn is from 20 to 40 cN/tex. 
     
     
         10 . The recycled fabric structure of  claim 1 , wherein a denier value of the blended yarn is from 150D to 600D. 
     
     
         11 . The recycled fabric structure of  claim 1 , wherein a thread count of the blended yarn is from 6 s to 20 s. 
     
     
         12 . The recycled fabric structure of  claim 1 , wherein the recycled fiber comprises one of cotton, polyester, polyamide or rayon, or a combination thereof. 
     
     
         13 . A knitted vamp cloth, comprising the recycled fabric structure of  claim 1 . 
     
     
         14 . A method of manufacturing yarn, comprising steps as follows:
 cutting a knitted cloth into a predetermined size;   applying an machinery fiber opening process to the cut knitted cloth to form a plurality of first fibers having a predetermined length, wherein a part of the plurality of first fibers comprises a nep;   mixing the plurality of first fibers and the plurality of second fibers to form a evenly mixed cotton layer; and   applying a cotton carding process and a doubling process to the mixed cotton layer, and applying a ring-spinning process to form an one-ply yarn;   wherein, the one-ply yarn has a random wire diameter and a color difference, the plurality of first fibers accounts for 30% to 50% of a total weight of the one-ply yarn, the nep of the plurality of first fibers has a random size, and a part of the plurality of first fibers forms a slub part of the one-ply yarn.   
     
     
         15 . The method of  claim 14 , wherein the knitted cloth is a knitted vamp cloth dyed with at least two colors. 
     
     
         16 . The method of  claim 14 , wherein the lengths of the plurality of first fibers and the plurality of second fibers are from 30 to 40 mm. 
     
     
         17 . The method of  claim 15 , wherein a slub of the plurality of first fibers has a random color. 
     
     
         18 . The method of  claim 14 , wherein a denier value of the one-ply yarn is in a range from 150D to 600D. 
     
     
         19 . The method of  claim 14 , wherein a thread count of the one-ply yarn is from 6 s to 20 s. 
     
     
         20 . The method of  claim 14 , wherein the plurality of first fibers comprises at least one type of yarn forming the recycled knitted cloth, and the type of yarn forming the recycled knitted cloth has a denier value from 75D to 600D and a polyfilament yarn number from 24 f to 72 f.
