Warp knit having an excellent touch, and a process of preparing the same

Abstract

The present invention relates to a warp knit having excellent touch and a process of preparing such a warp knit. The present invention provides a warp knit comprising three layers, namely a front surface layer, a rear surface layer, and an intermediate layer arranged between the front surface layer and the rear surface layer, the front surface layer consisting of ultra fine yarn with mono-filament denier of 0.01˜0.3 denier, the intermediate layer consist of spandex elastic yarn, the rear surface layer consisting of synthetic yarn or high shrinkage yarn with mono-filament denier of 1˜5 denier, wherein the recovery rate of elongation in the directions of wale and course is 25˜60 %. The warp knit according to the present invention is used to manufacture artificial leathers or ladies' clothes.

What is claimed is:  
     
         1 . A warp knit having excellent touch, comprising: three layers, namely a front surface layer, a rear surface layer, and an intermediate layer arranged between the front surface layer and the rear surface layer, the front surface layer consisting of ultra fine yarn with mono-filament denier of 0.01˜0.3 denier, the intermediate layer consist of spandex elastic yarn, the rear surface layer consisting of synthetic yarn or high shrinkage yarn with mono-filament denier of 1˜5 denier, wherein the recovery rate of elongation in the directions of wale and course is 25˜60%.  
     
     
         2 . The warp knit having excellent touch as claimed in  claim 1 , wherein content of the ultra fine yarn constituting the front surface layer is 40˜87% in weight of the total weight of the processed warp knit.  
     
     
         3 . The warp knit having excellent touch as claimed in  claim 1 , wherein content of the spandex elastic yarn constituting the intermediate layer is 3˜20% in weight of the total weight of the processed warp knit.  
     
     
         4 . The warp knit having excellent touch as claimed in  claim 1 , wherein content of the synthetic yarn or the high shrinkage yarn constituting the rear surface layer is 10˜57% in weight of the total weight of the processed warp knit.  
     
     
         5 . The warp knit having excellent touch as claimed in  claim 1 , wherein the density of the processed warp knit is 40˜80 each/inch.  
     
     
         6 . The warp knit having excellent touch as claimed in  claim 1 , wherein the ultra fine yarn and the synthetic yarn are polyester yarn.  
     
     
         7 . The warp knit having excellent touch as claimed in  claim 1 , wherein the high shrinkage yarn is co-polyester yarn with 15˜50% of shrinkage rate in boiling water.  
     
     
         8 . A process of preparing a warp knit having excellent touch, characterized in that firstly, knitting a warp knit by using a composite fiber consisting of a fiber formation component of 0.01˜0.3 denier and a extraction component as a yarn of a front surface layer, a spandex elastic yarn as a yarn of an intermediate layer, and a polyester yarn or high shrinkage yarn with mono-filament of 1˜5 denier as a yarn of a rear surface layer, and then raising the warp knit until the shrinkage rate of the warp knit is reached 40% or more, and then preliminarily heating, extracting the extraction component from the composite fiber, dyeing, buffing, and finally heating the warp knit continuously.  
     
     
         9 . The process of preparing a warp knit having excellent touch as claimed in  claim 8 , wherein ratio in weight of the yarn of the front surface layer: the yarn of the intermediate layer: the yarn of the rear surface layer is 40˜87% in weight: 3˜20% in weight: 10˜57% in weight.
