Comb tooth piece for weft-knitting computer jacquard cotton lace fabric and its production

Abstract

The invention provides a fabric for a weft knitting computer jacquard cotton lace. The fabric comprises spandexes of which the total denier of the same number is 40 D, polyamide filaments of 30D and cotton yarns of 44D, and a comb tooth part for producing the fabric comprises a first plate, a middle transition plate, a deflecting triangular part and a second plate, wherein one end of the middle transition plate is connected with the first plate, and the other end of the middle transition plate is connected with the straight edge of the deflecting triangular part; the diagonal edge of the deflecting triangular part is connected with one end of the second plate; the deflecting triangular part makes the second plate deflect relative to the first plate; the first plate is provided with a guidegroove extending in the length direction, and the guide groove is matched with a guide column inserted in the guide groove; the middle transition plate is provided with an articulated hole, and the articulated hole is matched with a pivotal shaft inserted in the articulated hole; the guide groove converts the linear motion of the guide column in the length direction of the first plate into the rotary motion of the comb tooth part around the pivotal shaft.

Description

technical field [0001] The invention relates to the technical field of computerized jacquard, in particular to a comb tooth piece used for weft-knitting computerized jacquard cotton lace fabric and its production. Background technique [0002] In the current daily consumer market, cotton fabrics are still one of the largest categories. The reason is that this category of fabrics is particularly suitable for human body wear. The comfortable and natural fabric style is an important advantage of its product popularity. A large number of new cotton weft-knitted flat fabrics, weft-knitted small loop fabrics, weft-knitted striped fabrics, and more plain, ribbed, cotton wool and other structures, rarely in the form of jacquard. The characteristics of singleness and insufficient pattern styles have restricted the development trend of enriching the patterns of underwear products. The emergence of cotton weft-knitted computer jacquard fabrics can fill this gap well, and rich fabrics c...

Problems solved by technology

[0003] However, in the prior art, cotton-spandex jacquard lace fabrics are easily entangled with elastic spandex yarns due to the large amount of flying flowers in the cotton yarn weaving process, which directly causes modern warp knitting machines to be difficult to weave such fabrics smoothly. Products, the research and development of cotton-spandex fabrics on warp knitting machines is also one of the important problems that the industry has not been able to completely overcome for many years, which has led to the phenomenon that the current warp knitting products are concentrated in the production of chemical fiber products only. In addition, , the computerized jacquard machine has restrictions on the types of raw materials on the machine, especially cotton yarns, because the range and degree of jacquard pattern change are much larger than those of conventional fabrics. Therefore, when the yarn participates in weaving, its yarn tension The fluctuation will be greatly increased, which will make it difficult for cotton jacquard to weave smoothly and efficiently
