Description

  This utility model relates to the technical field of warp knitted fabrics, and more particularly to warp knitted fabrics of composite spun yarns of long fibers and short fibers.

  A warp knitted product is a woven fabric formed by simultaneously knitting a loop of a set or a plurality of sets of warp yarns with a warp knitting machine and entwining each other. In this fabric, each yarn of a set of warp yarns is formed with only one or two yarn loops in a row of one yarn loop, and then again forms a yarn loop in the next row; formed with a single yarn The thread loop is provided along the longitudinal direction of the fabric.

  Among them, warp knitted fabrics are largely distinguished from woven fabrics and weft knitted fabrics; because warp knitting has a yarn loop structure, it belongs to a knitted product and has the characteristics of being soft, highly stretchable and elastic. Since the yarns are looped in the same transverse direction, there is a large difference between the stretchability in the transverse direction and the stretchability in the longitudinal direction, the anisotropy is clear, and the dimensional stability in the transverse direction is low; Since the wefts are entangled, the fabric dimensions are stable and the strength is high, but they are not soft, the stretchability is low, and wrinkles are likely to occur. On the other hand, in the case of warp knitting, the yarn is loop-formed with different yarn loops in the horizontal direction, so that the dimensional stability of the fabric is improved, and at the same time, it is soft, highly elastic and resistant. Warp knitting is an intermediate product between woven and flat knitted products.

Since warp knitting is produced by a high-speed loop forming knitting machine, high yarn strength, yarn unevenness and fluff are required. At present, all the raw materials for warp knitting machines are made of synthetic long fibers, which can satisfy the requirements of knitting machines.
However, as the demand for fashion and comfort increases, the need for warp yarns for warp knitted products is increasing in the market; short fiber, natural fiber cotton, hemp, wool and short fiber chemistry This is because fibers and the like have good touch and comfort. There are touch requirements that some become short fibers, and there are touch requirements that all become short fibers; at the same time, there is a trend in short fiber applications for 3D solid warp knitted fabrics with a certain thickness.

  The purpose of this utility model is to provide a warp knitted fabric of composite spun yarn of long fibers and short fibers, the warp knitted fabric of composite spun yarn of long fibers and short fibers is highly stable and soft, A flat warp knitted fabric or a 3D three-dimensional warp knitted fabric that is partly or entirely 100% short fiber yarn by adding soluble long fibers with good elasticity, high fender resistance, good touch and comfort. It is also possible to form a flat warp knitted fabric or a 3D solid warp knitted fabric that can be cut by any low-melting long fiber and has no edge bending change.
