CN-122013410-A - Color retention and multicolor production process of yarn-dyed strong-twist festooned fabric

Abstract

The invention belongs to the technical field of fabrics, and particularly relates to a color retention and multicolor production process of a yarn-dyed heavy twist textured fabric. The process comprises dyeing yarns with various colors, penetrating dye into the fibers, performing wet treatment on the yarns, performing heavy twisting, forming a tension buffer area through yarn feeding adjustment in the heavy twisting process to reduce tension fluctuation, weaving multicolor yarns through double warp beams to control tension difference of different yarns, and refining the woven fabric. Through the synergistic effect of the process steps, the color stability and multicolor effect consistency of the fabric are improved, and meanwhile, the stability in the production process is improved.

Description

Color retention and multicolor production process of yarn-dyed strong-twist festooned fabric Technical Field The invention belongs to the technical field of fabrics, and particularly relates to a color retention and multicolor production process of a yarn-dyed heavy twist textured fabric. Background At present, in the field of silk yarn-dyed fabrics, particularly in the field of leno fabrics, a plurality of color warp and weft yarn combinations are generally adopted, and the weaving is performed by combining a strong twisting yarn processing technology and a specific organization structure, so that the fabric with multicolor effect, three-dimensional texture and certain draping performance is obtained. In the production process, the yarn is generally dyed, and then twisted, woven, refined and the like, so that the dye is fixed on the fiber, thereby forming the fabric product with decorative and wearability. The existing technology can realize the multicolor effect and basic structural characteristics of the festoon fabric, but in practical application, the dye is not fully combined in the fibers, so that the fabric is easy to fade or change in color in the post-treatment process and the use process, the color stability is poor, the difference of the color absorption performance among yarns with different colors is large, the comprehensive color of the fabric is easy to be uneven, and the consistency of the multicolor effect is influenced. Meanwhile, in the processes of heavy twisting and floret weaving, yarn tension fluctuation is large, weaving is unstable, and the quality of the fabric is affected. Therefore, how to improve the color stability and consistency of multicolor effect of the fabric and the stability of yarn processing and manufacturing process in the production process of multicolor-woven heavy twist textured fabric is a technical problem to be solved. It should be noted that the above information disclosed in this background section is only for understanding the background of the inventive concept and therefore the above description is not to be construed as constituting prior art information.
