Process for Weaving Three-layer Warp-woven Fabric with Perspective Effect and Fabric Woven by the Same

Abstract

The disclosure relates to a process for manufacturing three-layer warp-woven fabric with a perspective effect and fabric woven by the same. A dual-needle-bed warp loom is used to weave the fabric; a front needle bed is programmed to weave transparent filaments. Distinguished from the prior art, in the disclosure, the transparent filaments are woven at the front needle bed, so that the fabric at the front needle bed becomes transparent, and the jacquard guide bar generates the weft insertion stitch at the front needle bed and the loop stitch at the rear needle bed, so that the front and rear needle beds of the jacquard guide bar weave different stitches to finally obtain three-layer warp-woven fabric with a perspective effect (the color and shape of the middle or bottom layer are visible), achieving an irregular concave-convex effect in different areas with color visible.

What is claimed is: 
     
         1 . A process for weaving three-layer warp-woven fabric with a perspective effect, the fabric woven using a dual-needle-bed jacquard warp loom, characterized in that,
 a front needle bed is programmed to weave transparent monofilaments, or a rear needle bed is programmed to weave transparent monofilaments, or the front and rear needle beds are both programmed to weave transparent monofilaments;   wherein a jacquard guide bar shuttles between the front needle bed and the rear needle bed to generate a middle jacquard design layer, and the jacquard guide bar generates weft insertion stitches at the front needle bed and loop stitches at the rear needle bed.   
     
     
         2 . The process for weaving three-layer warp-woven fabric with a perspective effect according to  claim 1 , wherein the yarn feeding speed of the front needle bed is 2000-3000 mm/rack. 
     
     
         3 . The process for weaving three-layer warp-woven fabric with a perspective effect according to  claim 1 , wherein the yarn feeding speed of the jacquard guide bar is 4000-10000 mm/rack at the front needle bed and 200-400 mm/rack at the rear needle bed. 
     
     
         4 . The process for weaving three-layer warp-woven fabric with a perspective effect according to  claim 1 , wherein the laid-in yarn stitch of the jacquard guide bar is any one of 1-0-0-0/0-1-1-1//, 1-0-1/1-2-1-1//, 1-0-1-0/1-2-1-2//, 1-0-1-0/1-2-1-2// and 1-0-1-2/2-3-2-1//. 
     
     
         5 . The process for weaving three-layer warp-woven fabric with a perspective effect according to  claim 1 , wherein two jacquard guide bars are provided, namely a first jacquard guide bar and a second jacquard guide bar, wherein the first jacquard guide bar shuttles between the front needle bed and the rear needle bed to form a jacquard middle layer, the first jacquard guide bar generates weft insertion stitches at the front needle bed and loop stitches at the rear needle bed;
 and the second jacquard guide bar jacquard weaves at the front needle bed or the rear needle bed.   
     
     
         6 . Three-layer warp-woven fabric with a perspective effect, comprising a surface layer, a bottom layer and a middle layer which connects the surface layer and the bottom layer;
 wherein the surface layer is woven with transparent monofilaments, the middle layer is a jacquard design layer, and a 0.5-10 mm wide pattern or character is formed in the middle layer through jacquard weaving.   
     
     
         7 . The three-layer warp-woven fabric with a perspective effect according to  claim 6 , wherein the surface layer and the bottom layer are both plain weave or jacquard design layers. 
     
     
         8 . The three-layer warp-woven fabric with a perspective effect according to  claim 6 , wherein the surface layer and the bottom layer are both mesh layers, and the surface layer and the bottom layer are different in mesh size.
