Low-tension knitting method of high-count single-strand wool yarn knitted fabric and knitted goods thereof

A technology for knitted fabrics and high-count wool yarns, which is applied to knitting, circular machines for weft knitting with individual moving needles, and weft knitting. It can solve problems such as large process resistance, high contact pressure, and rising tension. Achieve the effects of improving weaving efficiency, high twist unevenness, and reducing yarn breakage

Problems solved by technology

However, due to the low strength of single-strand high-count wool, the fineness, twist and strength unevenness are higher than other yarns, holes are prone to holes in the weaving process and the authenticity rate is low.
Moreover, due to the good elasticity of the wool fiber, the contact pressure of the new and old coils is high when they are interlaced with each other, resulting in large process resistance during the looping, looping and looping stages, and the tension of the yarn during the above looping stage rises sharply, which is likely to cause yarn breakage

Embodiment Construction

[0018] A low-tension high-count single-ply wool yarn knitted fabric weaving method, the raw material in this embodiment is single-ply high-count wool 72N / 1, and the high-gauge circular knitting machine is single-sided high-gauge (28 gauge and above) knitting Circular machine knitting. Specifically include the following steps:

[0019] Because the wool yarn has better elasticity than ordinary fibers in the stage of looping and looping, it can withstand greater looping resistance than ordinary fibers, so the cam that drives the movement of the knitting needle is improved as follows: increase the camber in the looping, continuous looping, and looping stages Slope, to control the downward movement and stop time of knitting needles, reduce the number of yarns bent between knitting needles, and reduce the rise of yarn tension (compared with the conventional 3-4G tension, it is about 20% lower); at the same time Shorten the flat width of the bottom of the pressing triangle (by 0.2 t...

Abstract

The invention discloses a low-tension knitting method of high-count single-strand wool yarn knitted fabric and knitted goods thereof. The method adopts a fine-gauge circular knitting machine to knit single-strand high-count wool yarn thin type knitted goods and comprises the following steps of: enlarging the triangle gradients in loop coiling, loop linking and loop forming stages and simultaneously shortening the bottom plane width of a needle-pressing triangle, therefore, apart from obtaining yarns required by loop forming from a yarn carrier when descending, the knitting needle returns part of yarns back from an adjacent loop-formed old yarn loop. The knitted goods are produced by the method. By optimizing the triangular design in a knitting needle drive system, the invention relieves the effects of the knitting needle and other loop-forming machines on the gripped or contacted yarns, reduces the technical resistance of new and old yarn loops in loop coiling and loop forming stages and causes the wool yarn loops with rigidity larger than common yarns to complete loop-forming action relatively smoothly, thus realizing the complete of the knitting technology under low tension condition.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a low-tension, high-count single-ply wool yarn knitted fabric weaving method and the knitted fabric. Background technique [0002] Wool has been recognized by consumers as the first choice raw material for high-grade warm-keeping knitted garments. Its weaving and finishing techniques are also very popular. But wool has not been used for long in thin, knitted underwear. With the continuous improvement of wool fiber quality and finishing technology, the itching of wool knitted underwear that once troubled consumers has been gradually solved, so that the production of wool knitted underwear has developed rapidly in recent years. The main reason is that wool has a series of unique properties, which endow knitted underwear with excellent wearability. Wool fiber has good elasticity, high degree of curl, and fluffy structure, so that static air is trapped inside the wool...
