The knitting method of multi-bar warp knitting machine

Abstract

The invention provides a knitting method of a multi-bar warp-knitting machine. The method includes the following steps of firstly, preparing a raw material wire; secondly, feeding the raw material wire into a looping ground bar; thirdly, making the looping ground bar start knitting, wherein the raw material wire is composed of N yarns, N is larger than or equal to 1, and at least one of the N yarns is a raveling-resistant yarn. Raveling-resistant yarn loops are added on the basis of existing loops, the tightness of the existing loops is increased, joints of all the loops are staggered or overlapped, ground net yarn loops are made to have quite strong cohesive force and more closely cohered to fancy yarns forming a pattern, and even no chain stitch transfer transverse yarn or thermofuse yarn is added, the ground yarn loops and the fancy yarns are not prone to raveling after damage.

Description

technical field [0001] The invention relates to the field of knitting, in particular to a knitting method of a multi-bar warp knitting machine. Background technique [0002] The use of multi-bar warp knitted fabrics in various aspects such as clothing fabrics, decorative materials, and industrial materials is increasing day by day, and the development and market application of multi-bar warp knitted fabrics are also changing with each passing day. Ordinary multi-bar warp-knitted fabric floor nets are easy to fall apart under the action of external forces (including washing, pulling, etc.) This performance is opposite to other performances. When the release performance is reduced in manufacturing, other performances are reduced or lost. The methods and disadvantages of the currently commonly used multi-comb warp knitted fabrics to prevent or resist detachment: increase the longitudinal density during weaving to improve the detachment resistance, but increase the cost of mult...

Problems solved by technology

At the same time, because the weft-inserted ordinary spandex yarn itself is not firmly connected with the loop-forming yarn or other yarns, the risk of spandex shedding also varies depending on the density and yarn thickness, such as Figure 8 and 9 It shows that when the longitudinal weaving density of the loop is not large enough, the yarn is still easy to fall apart after being subjected to external force

The disadvantage of this method is that it is difficult to grasp the effect of suppressing detachment. When the longitudinal density of the ground comb coil is high, the feeding amount of the unit coil of the ground yarn becomes smaller, resulting in a decrease in elasticity. When it is increased, the risk of unraveling will also increase. In order to ensure that it does not unravel, it is often necessary to greatly increase the longitudinal density during weaving, which will lead to a large decrease in longitudinal elasticity, hardening of the fabric feel, and poor shrinkage.

The disadvantage of this method is that the position of the straight knitting chain is still easy to fall off; when the hexagonal lines are sparse, the overall anti-scattering effect is not obvious; and the surface of the fabric has a bad appearance of horizontal stripes. When the hexagonal lines are dense, the mesh of the knitted fabric is blurred and the appearance is greatly affected. influences

[0009] In summary, in multi-bar warp knitted fabrics, the traditional and existing methods of preventing or inhibiting fabric delamination have many disadvantages, including sacrificing fabric elasticity, deteriorating hand feeling, high cost, and deteriorating appearance. Even cause problems such as skin irritation and unknown effects
