Dyeing and finishing process of coffee-yarn blended and knitted fabric

Abstract

The invention discloses a dyeing and finishing process of a coffee-yarn blended and knitted fabric. The dyeing and finishing process is characterized by comprising the following steps: preparing grey fabric, pretreating, dyeing, soaping, softening and carrying out after finishing, wherein a mild pre-treatment degreasing process is adopted; and an active double-dyeing process of firstly dyeing, dispersing and dyeing is adopted to dye, so that the difficulty in dying with the same color of the blended and knitted fibers is solved; through control on a finishing agent and the amount of the finishing agent in the after finishing process of the coffee-yarn blended and knitted fabric, the problems of same color and different colors in the dyeing process of the coffee-yarn blended and knitted fabric are solved; good air permeability and relatively good rubbing fastness are obtained; and meanwhile, a plurality of efficacies that the coffee-yarn blended and knitted fabric is capable of absorbing stink, removing an odor, storing heat, keeping warm, absorbing moisture and drying quickly in an far infrared manner are taken into account.

Description

Technical field: [0001] The invention relates to a dyeing and finishing process of fabrics, in particular to a dyeing and finishing process of coffee yarn blended and blended fabrics. Background technique: [0002] Coffee yarn refers to a special textile fiber made of recycled coffee grounds imported into polyester-based fibers. It not only has a wide range of raw material sources, but also has a low-carbon and environmentally friendly production process. It is made of coffee yarn or blended with coffee yarn and other fibers. The fabric has excellent properties such as odor absorption and deodorization, heat storage and warmth, far-infrared, moisture absorption and quick-drying. This kind of coffee yarn conforms to the concept of green environmental protection and fashion. Carbon" has gradually become people's new favorite. [0003] However, at present, coffee yarn fabrics, especially coffee yarn blended fabrics, have not been researched and applied on a large scale. Fastn...

AI Technical Summary

Problems solved by technology

[0005] Third, when the coffee yarn blended blended fabric is set, because the disperse dyes are prone to migration during the high-temperature setting process, the fiber friction and wash fastness will be reduced, and the color and color of the active material will also change at different setting temperatures. There will be a certain change, which will also have a subsequent impact on the same color dyeing

[0006] After literature search, no technical literature or patent reports on the dyeing and finishing of coffee yarn blended fabrics have been found.
