Problems solved by technology

[0003] Aiming at the above-mentioned problems of relatively poor elasticity and recovery of terry fabrics existing in the prior art, the present invention provides a production method of 360° omni-directional elastic knitting fabrics. It can reach more than 220%, and its recovery rate after stretching can reach more than 80%. In addition, a circular knitting machine that can be used to produce the elastic knitted fabric is provided, and spandex yarn feeding is added to the existing single-jersey circular knitting machine system, and improved the spandex yarn guide, non-knitting knitting cams and looping tuck cams, realized stable and smooth spandex yarn feeding, and improved fabric production efficiency and product quality

Embodiment 1

[0038] This embodiment provides a circular knitting machine for producing 360° omnidirectional elastic knitting needle fabric. The spandex yarn delivery system 1 is installed on the single jersey circular knitting machine, the spandex yarn guide 2, the loop forming triangle 3 and the failure Circle knitting triangle 4.

[0039] Such as figure 1 As shown, the spandex yarn feeding system 1 includes a circular fixing frame 11 (only a part is shown in the figure, and the rest of the structure is the same), a spandex yarn feeder 12, a yarn feeding timing belt 13 and a spandex yarn breaking automatic stop device 14. The circular fixing frame 11 is arranged on the periphery of the creel of the circular knitting machine. A number of spandex yarn feeders 12 are arranged at equal intervals on the circular fixing frame 11 for conveying spandex yarn. At least two spandex yarn feeders 12 are arranged in parallel. The wire feeding roller 121 is used to place the spandex spool 15 between the fe...

Embodiment 2

[0051] This embodiment provides a 360° omnidirectional elastic knitting needle fabric knitting method, using the circular knitting machine provided in embodiment 1, knitting a knitting course every three passes, as a looping system, divided into loop yarn, surface yarn, Ground yarn, loop yarn is 18.2tex compact spun yarn, loop length is 175mm / 100 buckle, surface yarn is 14.6tex compact spun yarn, loop length is 400mm / 100 buckle, ground yarn is 33dtex spandex yarn, loop length is 128mm / 100 deduction.

[0052] The weaving process is as follows:

[0053] The first way: the A needle butt machine needle with the starting triangle cooperates with the sinker to knit the grey fabric cushion yarn as the loop yarn;

[0054] The second way: all machine needles can knit triangle knitting table yarn without looping, and realize the loop of the yarn loop off when knitting the triangle bending yarn, and the table yarn loop does not fall off;

[0055] The third way: All the needles follow the loop-...

Abstract

The invention provides an elastic knitted fabric knitting method. Every three lines form a knitting transverse row by knitting to serve as a cam system and include loop yarns, surface yarns and groundyarns, an integral binding effect of the loop yarns on gray cloth is weakened, an underfilling coefficient of surface yarn loops is increased, and polyurethane filaments are capable of giving play toan elastic effect. A fabric produced according to the method reaches 220% or above in transverse and longitudinal elongation and reaches 80% or above in after-stretching recovery rate. The inventionfurther provides a circular knitting machine which can be used for producing elastic knitted fabrics. By additional mounting of a polyurethane yarn conveying system on an existing single-side circularknitting machine and improvement of a polyurethane yarn guide, a non-loop knitting cam and a looping tucking cam, stability and smoothness in polyurethane yarn feeding are realized, and fabric production efficiency and product quality are improved.

Description

Technical field [0001] The invention belongs to the technical field of knitting, and specifically relates to a knitting method of a 360° omnidirectional elastic knitting needle fabric and a circular knitting machine. Background technique [0002] Home clothing is a product category that has been subdivided from pajamas in recent years, and its good wearing comfort is an important indicator of this type of product. Therefore, fabrics for home furnishings need to have good elasticity to ensure that the clothes are loose and comfortable. At the same time, they also need to have good resilience to ensure that the fabrics are not easily deformed. At present, the fabrics used in home furnishings on the market are generally high-elastic loop fabrics. The preparation process of this type of fabric is a two-thread loop structure made by adjusting the knitting triangle on the basis of a jersey machine. The fabric is given by adding spandex yarn. Certain stretch elasticity. However, the f...
