Abstract

The invention provides a color-retaining finishing method of a jean fabric, a microcapsule structure and the jean fabric. The color-retaining finishing method of the jean fabric comprises the following steps of S1, carrying out acid treatment on the jean fabric; S2, carrying out drying treatment on the jean fabric obtained in the step S1; S3, preparing the microcapsule structure, wherein the microcapsule structure is composed of a wrapping wall and a color retaining solution contained in the wrapping wall, the wrapping wall consists of paraffin and C5 resin, and the color retaining solution contains a water-based color fastness improver and water-based polyurethane; S4, mixing the microcapsule structure obtained in the step S3, resin, a slipping agent and a cross-linking agent to obtain a coating solution, and performing coating treatment on the jean fabric obtained in the step S2 by adopting the coating solution; and S5, performing baking treatment on the jean fabric obtained in the step S4. According to the invention, indigo dye of the jean fabric is covered with a double-layer film formed by the water-based color fastness improver and the resin, so that the color retaining effect of the jean fabric is further improved.

Description

technical field [0001] The application relates to the field of post-finishing of denim fabrics, in particular to a method for color-preserving finishing of denim fabrics, a microcapsule structure and denim fabrics. Background technique [0002] Denim clothing is still one of the most popular clothing types in the past and present. Different from other casual clothing, the style design of denim clothing has not changed much. What makes it constantly on the forefront of fashion is the ever-changing finishing process. The finishing process endows denim clothing with more added value, thereby improving The competitiveness of denim clothing in the market meets the needs of consumers. [0003] The traditional denim fabric is made of indigo pure cotton yarn as the warp yarn and the white weft yarn. Since the indigo dye and the yarn fibers are combined by hydrogen bonds or Van der Waals force, the binding ability is weak. The finished denim clothing will fade seriously when washed...
