AI Technical Summary
Technical Problem
The existing chenille yarns are limited in color, difficult to dye, and have monotonous colors, resulting in limited color variations in chenille fabric patterns.
Method used
Hydrophobically modified polyester macrofiber and cationic modified polyester filament are used as core yarn and pile yarn. Through two dyeing processes, cationic dyes and oil-soluble dyes are used to dye the pile yarn and core yarn respectively, forming a distinct two-color effect.
Benefits of technology
It achieves more vivid color contrast, higher color fastness, soft and fluffy hand feel in chenille yarn, and the dyeing process is simple and low-cost.

Abstract
This application belongs to the field of textile technology and discloses a pure polyester two-tone chenille yarn and its preparation process. The preparation process of the pure polyester two-tone chenille yarn in this application includes the following steps: (1) preparing core yarn and pile yarn; (2) cutting and twisting to obtain finished yarn; (3) performing two dyeing and color fixing processes in sequence to obtain pure polyester two-tone chenille yarn. The raw materials of the chenille yarn obtained in this application are all replaced by polyester fibers, and a similar fluffy and soft hand feel can be obtained. At the same time, in the dyeing process, the pure polyester two-tone chenille yarn dyed by the two-bath dyeing method has a more vivid color contrast between the core yarn and the pile yarn, the color is more bright, the color fastness is higher, and the tensile strength and reliability of the chenille yarn are maintained as much as possible.
