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 in particular relates to a knitting method of a 360° omnidirectional elastic knitted fabric and a circular knitting machine. Background technique

[0002] Home clothing is a product category subdivided from pajamas in recent years, and its good wearing comfort is an important indicator of this type of product. Therefore, fabrics for home clothing need to have good elasticity to ensure that the clothes are loose and comfortable to wear. At the same time, they also need to have good resilience to ensure that the fabric is not easily deformed. At present, the fabrics used in home clothing on the market are generally high-elastic terry fabrics. The preparation process of this kind of fabrics is based on the jersey machine, and the two-thread terry weave is produced by adjusting the knitting triangle, and the fabric is endowed with spandex yarn. Certain stretch elasticity. However, the fabric o...

Examples

Embodiment 1

[0038] This embodiment provides a circular knitting machine for producing 360° omnidirectional elastic knitting fabrics. A spandex yarn delivery system 1 is set on the single-jersey circular knitting machine, and a spandex yarn guide 2, a loop-forming and tucking cam 3 are improved, and Circle knitted triangle4.

[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 remaining parts have the same structure), a spandex yarn feeding device 12, a yarn feeding timing belt 13 and a spandex yarn breaking automatic stop device 14. Circular fixed frame 11 is arranged on the periphery of the creel of circular knitting machine, and several spandex yarn feeders 12 are arranged at equal intervals on circular fixed frame 11, are used for conveying spandex yarn, and at least two spandex yarn feeders 12 are arranged in parallel The wire feeding roller 121 is used to place the spandex bobbin 15 bet...

Embodiment 2

[0051] This embodiment provides a method for knitting a 360° omni-directional elastic knitted fabric. The circular knitting machine provided in Embodiment 1 is used to weave a knitting course every three ways. As a loop forming system, it is divided into loop yarn, surface yarn, Ground yarn, loop yarn is 18.2tex compact spun yarn, loop length is 175mm / 100 buttons, surface yarn is 14.6tex compact spun yarn, loop length is 400mm / 100 buttons, 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-heel machine needle follows the needle-lifting triangle and the sinker to weave the gray cloth lining yarn as the loop yarn;

[0054] The second way: all the needles knit the surface yarn of the triangle knitting without knitting, and the loop yarn loops can be removed when knitting the triangle bending yarn, and the surface yarn loops can not be looped;

[0055] The third way: All the needles a...
