Abstract

The present disclosure relates to an elastic fiber, an elastic fiber covered yarn and reeling manufacturing methods thereof. The reeling manufacturing method of an elastic fiber includes: providing an elastic fiber material, the elastic fiber material having a core portion and a skin portion, the skin portion covering the core portion; performing a first extending, to have the elastic fiber material passing a first guiding roller, the speed of the first guiding roller being 500-1500 m/min; performing a second extending, to have the elastic fiber material passing a second guiding roller, the speed of the second guiding roller being 1200-2400 m/min; and performing a third extending, to have the elastic fiber material passing a third guiding roller, the speed of the third guiding roller is 1300-2600 m/min.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A reeling manufacturing method of an elastic fiber, comprising:
 providing an elastic fiber material, the elastic fiber material having a core portion and a skin portion, the skin portion covering the core portion;   performing a first extending, to have the elastic fiber material passing a first guiding roller, the speed of the first guiding roller being 500-1500 m/min;   performing a second extending, to have the elastic fiber material passing a second guiding roller, the speed of the second guiding roller being 1200-2400 m/min; and   performing a third extending, to have the elastic fiber material passing a third guiding roller, the speed of the third guiding roller is 1300-2600 m/min.   
     
     
         2 . The reeling manufacturing method of  claim 1 , wherein the speed of the first guiding roller is 550-1300 m/min, the speed of the second guiding roller is 1300-2000 m/min, the speed of the third guiding roller is 1350-2500 m/min. 
     
     
         3 . The reeling manufacturing method of  claim 1 , wherein further includes a winding step, to have the elastic fiber material passing a winding roller for winding, the speed of the winding roller being 1250-2250 m/min. 
     
     
         4 . The reeling manufacturing method of  claim 1 , wherein the reeling temperature of the elastic fiber material may be 160-240° C. 
     
     
         5 . The reeling manufacturing method of  claim 1 , wherein the temperature of the first guiding roller is 10-75° C., the temperature of the second guiding roller is 10-75° C., the temperature of the third guiding roller is 10-75° C. 
     
     
         6 . A reeling manufacturing method of an elastic fiber covered yarn, comprising:
 providing an elastic fiber covered yarn material, the elastic fiber covered yarn material having an elastic fiber and a plurality of peripheral fibers, the plurality of peripheral fibers surrounding the elastic fiber;   performing a first extending, to have the elastic fiber covered yarn material passing a first guiding roller, the speed of the first guiding roller being 2000-4500 m/min; and   performing a second extending, to have the elastic fiber covered yarn material passing a second guiding roller, the speed of the second guiding roller being 2500-4500 m/min.   
     
     
         7 . The reeling manufacturing method of  claim 6 , wherein the speed of the first guiding roller is 2500-4500 m/min, the speed of the second guiding roller is 3000-4000 m/min. 
     
     
         8 . The reeling manufacturing method of  claim 6 , wherein further comprising a winding step, to have the elastic fiber material passing a winding roller for winding, the speed of the winding roller is 2500-5000 m/min. 
     
     
         9 . The reeling manufacturing method of  claim 6 , wherein the reeling temperature of the elastic fiber covered yarn material is 240-320° C. 
     
     
         10 . The reeling manufacturing method of  claim 6 , wherein the temperature of the first guiding roller is 10-75° C., and the temperature of the second guiding roller is 10-75° C. 
     
     
         11 . The reeling manufacturing method of  claim 6 , wherein routine material of the plurality of peripheral fibers comprises polyethylene terephthalate, polybutylene terephthalate, nylon 6 or nylon 66. 
     
     
         12 . The reeling manufacturing method of  claim 11 , wherein material of the plurality of peripheral fibers further comprises a recycled material. 
     
     
         13 . The reeling manufacturing method of  claim 12 , wherein the routine material and the recycled material of the plurality of peripheral fibers are mixed at a weight ratio of 55%:45% to 100%:0%. 
     
     
         14 . The manufacturing method of  claim 6 , wherein manner in which the plurality of peripheral fibers surround the elastic fiber comprises a Single Covered Yarn (SCY), a Double Covered Yarn (DCY), an Air-Jet Covered Yarn (ACY) or an Air textured Yarn (ATY).
