Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of textiles, and relates to a weaving method for forming a three-dimensional trim. BACKGROUND

[0002] The plain weft-knitted fabric is a common weaving structure in textile production, which can be applied to the production of various types of fabrics and has a wide range of applications.

[0003] When a three-dimensional trim needs to be knitted on the plain weft-knitted fabric, the traditional method is to use hand sewing. This method is not only time-consuming and laborious, but also the connection between the fabrics is not neat, and the fabric elasticity is inconsistent, which affects the product quality.

[0004] In addition to the manual weaving method, a computerized flat knitting machine can also be used to weave the trim. At present, a sinker is generally used to press and pull the knitted loops. However, this pressing and pulling method is prone to cause flying yarn and loop floating during knitting, and the number of continuous pressing times is also limited. The shape of the knitted trim is small, the qualified rate is low, and the method has limitations in adapting to wool yarn. The three-dimensional effect is not obvious. SUMMARY

[0005] In order to improve the problems of flying yarn and loop floating when the sinker is pressed and pulled, the present application provides a weaving method for forming a three-dimensional trim, and the specific steps are as follows:

[0006] Step one: on the plain single-sided knitted fabric of the front needle bed of the computerized flat knitting machine, the loops on the knitting needles in the trim part are set, the loops on the adjacent two knitting needles on the front needle bed are turned into the corresponding idle knitting needles on the back needle bed, the knitting needles in the trim part on the front needle bed are set as empty, and there is one idle knitting needle between the two knitted loops on the knitting needles in the trim part on the back needle bed;

[0007] Step two: on the set trim part, the idle knitting needles on the back needle bed are hung with trim loops at an interval of one knitting needle with the front needle bed, and the idle knitting needles on the back needle bed are hung with trim loops at an interval of one knitting pitch with the adjacent knitting needles on the front needle bed. The two needle beds are simultaneously ejected to start knitting, forming a 1-by-1 rib structure in the trim part. When knitting the rib structure, the newly knitted trim loops are pressed and pulled downward. For example, a presser foot is used to press and pull the newly knitted trim loops downward from top to bottom. The presser foot is driven by a presser ring device to press and pull the newly knitted trim loops downward from top to bottom. The presser foot is reciprocally pressed and pulled, and the knitting is reciprocally carried out until the trim is knitted completely.

[0008] Step three: after the trim is knitted completely, the loops on the knitting needles on the back needle bed are turned into the corresponding original positions on the front needle bed, and the plain weft-knitting on the front needle bed is restored. After the plain weft-knitting is completed, the fabric is finished.

[0009] Through the above steps, on the one hand, the three-dimensional trim can be knitted on the weft flat fabric, instead of manual sewing method, and the knitting efficiency is improved, and on the other hand, the fabric has needle-to-needle, and the convex seam without sewing connection is soft and harmonious.

[0010] The presser foot is pressed from top to bottom by the pressing ring device, so that the knitted loop can be pressed and pulled, thereby improving the timeliness and accuracy of the pulling operation, preventing the loop from floating, shifting or deforming, helping to form the required rib structure, and also maintaining the proper tension of the fabric during knitting, and proper pressing and pulling also helps to control the size and shape of the fabric, and enhances the stability and beauty of the fabric.

[0011] The present application has the beneficial technical effects:

[0012] 1. The three-dimensional trim is knitted by the flat knitting machine, instead of manual sewing method, and the knitting efficiency is improved, and the cost of manual sewing can also be reduced, and the main fabric and the trim fabric are needle-to-needle and integrated, without sewing seam, soft and harmonious, and the elasticity is consistent, which is beneficial to improve the product quality.

[0013] 2. The newly knitted loop is pressed and pulled from top to bottom by the presser foot, effectively fixing the position of the loop, preventing the loop from floating, shifting or deforming during knitting, and helping to keep the loop stable, so that the knitting actions such as purling, shifting, looping, unlooping and looping can be accurately performed.
