Preparation method and application of multi-component intervening spinning colorful yarn

Abstract

The invention discloses a preparation method and application of multi-component intervening spinning colorful yarn, and belongs to the technical field of spinning weaving. The multi-component intervening spinning colorful yarn comprises main yarn and auxiliary yarn; the main yarn is formed by drafting rough yarn; the auxiliary yarn is discontinuously mixed on the main yarn, and the auxiliary yarn serves as a repeating unit and is discontinuously distributed in the length direction of the main yarn; and the auxiliary yarn comprises a plurality of yarn sections of a, b, c, d, e and f, and the yarn sections are distributed in any sequence in the length direction of the main yarn. The preparation method of the yarn sequentially comprises the following steps of doubling, roving and fine spinning. The application of the colorful fabric in the field of colorful fabric preparation is as follows: the fabric is formed by weaving multicomponent intervening spun multicolor yarns as warp yarns or / and weft yarns, and then dyeing is carried out by adopting cationic dyes. The interventional spinning colorful yarn is thin, relatively high in strength and relatively uniform in strength performance, and the dyed yarn is changed in depth; and the prepared colorful fabric can realize two purposes of one fabric, is a white fabric before being dyed, and can present bamboo-like colorful patterns after being dyed.

Description

technical field [0001] The invention discloses a preparation method and application of a multi-component intervening spinning illusion yarn, belonging to the technical field of spinning and weaving. Background technique [0002] Illusion yarn belongs to a kind of colored yarn. In the prior art, it refers to a yarn whose color changes along the length direction of the yarn. In the prior art, the preparation method of the illusion yarn mostly adopts dyeing of fibers or fiber strips first, and then drawing colored fiber strips, roving, and fine sand to obtain yarns. Because the existing illusion yarn itself is colored, colored yarn-dyed fabrics can be obtained through yarn-dyed weaving. [0003] The applicant found in the research that the existing illusion yarns have the following problems: although the first yarn-dyed fabric can show patterns, the color is determined by the illusion yarns, which is not flexible enough; in the prior art, the same pattern is often produced Fo...

Problems solved by technology

[0003] The applicant found in the research that the existing illusion yarns have the following problems: although the first yarn-dyed fabric can show patterns, the color is determined by the illusion yarns, which is not flexible enough; in the prior art, the same pattern is often produced For close-fitting clothing of different colors, white is the best-selling color, while yarn-dyed fabrics have a fixed color and cannot be made into white clothing; for example, a shirt of the same style can be produced in white, blue, and pink, of which white is the basic and The most sold, the rest of the colored models have frequent color changes

[0004] Second, when colored yarns are used to make fabrics, there will be color flower problems

Therefore, it is difficult to correct when the color flower problem occurs on the existing phantom yarn

[0005] Third, it is difficult to produce high-count illusion yarn, and it is easy to have problems of insufficient strength and uneven strength

Symphony yarn is mostly spun by blending. In the prior art, the yarn is divided into sections according to the color, and the proportion of each section of fiber strips is quite different. This will inevitably lead to large differences in the strength of each section of the yarn and unstable strength. , when making thicker yarns, this problem is not obvious, but it is difficult to make high-count thin yarns with high strength and stable strength of more than 40 counts, so it is difficult to make high-count clothing fabrics

[0006] Fourth, the existing illusion yarn has the problem that the color changing effect is not obvious, and the change of the yarn color is blurred, resulting in blurred patterns of the woven fabric
