Tri-knit comfort fabric and methods for preparing and using the fabric

Abstract

A tri-knit comfort fabric and a preparation method and application thereof. The preparation method includes steps of knitting a raw material with a three-thread yarn feeder to obtain a primary fabric, performing a greige fabric stenter finishing process on the knitted primary fabric, dying the primary fabric, then dewatering, treating through a flat-width fabric dryer and performing the stenter finishing process to the dyed fabric to obtain the tri-knit comfort fabric. The preparation method improves the wearing comfort and moisture wicking function of the three-thread fabric, and the fabric prepared by the three-thread knitting method of adding the polyester component can be iron-free after washing. In addition, its moisture wicking, quick drying, water permeability, breathability and antistatic properties are also very good. It can also be separately added with independent functions such as thermal insulating, ice-feeling, anti-UV, antibacterial, anti-mildew and anti-mite. The process is simple, convenient for mass production.

1 . A method for preparing a tri-knit comfort fabric, comprising steps of:
 a) knitting a raw material with a three-thread yarn feeder to obtain a primary fabric containing three types of yarns: top layer yarn, intermediate layer yarn and bottom layer yarn;   b) performing a greige fabric sternter finishing process on the primary fabric knitted in step a) at a first predetermined temperature;   c) dyeing the primary fabric treated in step b), then dewatering and treating through a flat-width fabric dryer; and   d) performing a stenter finishing process to the primary fabric treated in step c) at a second predetermined temperature to obtain a finished product of tri-knit comfort fabric.   
     
     
         2 . The method in  claim 1 , wherein in step a): at least one of the three yarns is a blended yarn; the blended yarn is at least two of polyester fiber, synthetic fiber and natural fiber; and other two of the three yarns are at least one of elastic fibers, polyester fibers, synthetic fibers, and natural fibers. 
     
     
         3 . The method in  claim 1 , wherein: the top layer yarn has a density number of 30 cm to 37 cm; the intermediate layer yarn has a density number of 8 cm to 12 cm; and the bottom layer yarn has a density number of 29 cm to 36 cm. 
     
     
         4 . The method in  claim 1 , wherein in step b), a speed upon greige fabric stenter finishing is 20 yards to 25 yards. 
     
     
         5 . The method in  claim 1 , wherein in step d), a speed upon dyed fabric stenter finishing is 18 yards to 22 yards. 
     
     
         6 . The method in  claim 1 , wherein in step b), the first predetermined temperature is 190° C.-200° C. 
     
     
         7 . The method in  claim 1 , wherein in step d), the second predetermined temperature is 145° C.-155° C. 
     
     
         8 . A tri-knit comfort fabric prepared by the method in  claim 1 . 
     
     
         9 . A method for using for clothing and home textiles, the tri-knit comfort fabric prepared by the method in  claim 1 .
