Description

A double-sided bubble woven fabric with positive and negative concave and convex

Technical Field

The utility model relates to the technical field of woven fabrics, in particular to a front and back concave-convex double-sided bubble woven fabric.

Background Art

Double-sided bubble woven fabric with positive and negative convex and concave structures refers to a fabric with a concave and convex structure on the surface of the fabric. Based on the concave and convex structure, different usage effects can be produced according to different application scenarios.

The concave-convex warp knitted fabric in the prior art is a warp knitted fabric with a concave-convex jacquard effect on the surface, and its implementation principle is: the comb GB1, jacquard comb JB1.1, jacquard comb JB1.2, jacquard comb JB2.1, and jacquard comb JB2.2 all use low-elastic yarn or inelastic yarn for threading, and the yarn rebound after weaving is relatively small or there is no rebound. The combs GB4 and GB5 use medium-high elastic yarn, and the yarn rebound after weaving is relatively increased. The yarn will shrink toward the bottom layer, so that the surface flat cloth position is convex, forming a concave-convex structure with a certain elasticity. Because the jacquard bars JB2.1 and JB2.2 selectively pad yarn from the surface layer to the bottom layer, the fabric is woven to form a non-delamination effect, so that the bottom layer and the surface layer of the fabric are tightly woven and connected to form a whole without gaps. Therefore, the surface layer flat cloth position where the jacquard bars JB2.1 and JB2.2 are located is not raised, forming a stable structure, making the concave and convex jacquard effect of the fabric obvious. It can be seen that it needs to rely on the material matching and form a concave and convex jacquard effect through a certain weaving method on a double needle bed warp knitting machine, which has certain limitations and the three-dimensional structure is general.

Based on this, the inventor studied and proposed this case.
