Multi-color gradual-change digital yarn knitted fabric and preparation method thereof

Abstract

The invention relates to the technical field of textile, and particularly relates to a multi-color gradual-change digital yarn knitted fabric preparation method. The method comprises the following steps: A) yarn production process: selecting cotton fibers with three colors of cyan, magenta and yellow as raw materials to perform roving and sliver spinning, wherein the yarns are spun by using a digital spinning machine; the changing amount of the blending ratio of different colors is 10 percent, and the changing length of each ratio is 6 cm; the spun 30 S gradient yarn and the 30 S pure yellow yarn are simultaneously combined; B) the knitting process of a flat knitting machine: knitting on a computer flat knitting machine, wherein the fabric adopts a fabric weave as a single-side flat needle; transverse density: 62.5 / 10 cm; longitudinal density: 39 / 10 cm. According to the multi-color gradual-change digital yarn knitted fabric and the preparation method thereof, the fabric has the advantages of unique style, rich layers, strong three-dimensional feeling and fashion feeling, and wide application prospect.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a colorful gradient digital yarn knitted fabric and a preparation method thereof. Background technique [0002] Since the 1980s, knitted garments have been increasingly favored by people all over the world, and the world's clothing field has shown a trend towards knitted garments. Knitted fabric, as the main raw material of knitted garments, not only has the general characteristics of knitted garments, but also has a unique personality, forming a unique style with its excellent properties of softness, comfort, fit and elasticity. Especially in the new century, the leisure and fashion of knitted fabrics conform to the changes in people's lifestyles. The development of raw materials towards natural and environmental protection and the development of fabrics towards functionalization has occupied an increasingly important position in the modern clothing industry and has become It ...

Problems solved by technology

[0010] On the basis of the three rollers, add a rear roller. The top rubber rollers of the three rollers and four rollers use stepped rubber rollers to hold the two rovings fed respectively. The main core yarn is fed from the four rollers, and the auxiliary yarn is fed from the three rollers. Roller feeding, the roving sliver is controlled by the stepped rubber roller and passes over the smaller diameter end of the stepped rubber roller, while the roving sliver passes over the smaller diameter end of the stepped rubber roller and is controlled by the stepped rubber roller, the program controller Control the servo motor so that the three-roller and four-roller are driven by variable speed in stages, and they are assembled in the main drafting composed of one roller and two rollers to achieve the effect of segmented colored yarn; the segmental color control principle and spinning effect are the same as those of the three-roller drafting method Similar, the difference is that the speed of the three-roller and four-roller can be both, the main yarn increases the draft control in the rear area, and the yarn evenness is relatively good, but the gripping points of the three-roller and four-roller on the roving are relatively The distance between the two rollers is different, which is not suitable for drafting and spinning of cotton-type fiber sliver. At the same time, the holding points of the three rollers and four rollers for the roving are not at the same point of the length of the roving fed, so they cannot be synchronized and the speed control is controlled at the same point. Yarn evenness, complicated process adjustment

Although the four-roller method can spin relatively uniform segment colored yarns, the blending ratio of the main and auxiliary yarns is not convenient to adjust and control due to the limitation of the main and auxiliary roving weight and the draft ratio of the rear area.
