Problems solved by technology

[0004] In the prior art, the printing and dyeing of cotton and linen products is a one-time dyeing and weaving, which is easy to lose color, dyeing and other problems. If the washed cotton and linen products are placed in the sun, the color of the cotton and linen fabrics will easily fade. This is an urgent hope. It is possible to find a method of printing and dyeing cotton and linen fabrics with wet fastness and light resistance

Abstract

The invention discloses an environmentally-friendly dyeing method of a cotton and ramie fabric. The method concretely comprises the steps of weaving, desizing, cellulase finishing, baking, dyeing, softener application, baking, non-iron finishing and packaging. A slurry on clothes can be removed through desizing, and biological polishing finishing and the non-iron finishing are adopted to make the satisfactory cotton and ramie fabric. The fabric has obvious effects and very good practical values, and the method has the advantages of energy saving, environmental protection, realization of very good wet treatment fastness and solarization resistance of the cotton and ramie fabric dyed through the method, and solving of the color light change and easy fading in the prior art.

Description

technical field [0001] The invention relates to the field of clothing fabrics, in particular to an environmentally friendly dyeing method for cotton and linen fabrics. Background technique [0002] Cotton and hemp are grown from temperate plants. The seeds of cotton and hemp are harvested, dried in the sun, threshed by machine, decomposed into seeds and cotton and hemp, pressed by machine, and then spun into threads, cloth, Finally, after dyeing, the finished product. [0003] Cotton and linen clothes have returned to people's sight again, which has set off a retro fashion trend. Because cotton and linen are coarse cloths, they are all hand-sewn. The production process is green, natural and environmentally friendly. From planting to hand-woven products, no pesticides and chemical dyes are used. The textiles do not contain methanol, azo and other chemical harmful substances. The most suitable personal textiles for the human body. With its soft texture, warm in winter and c...
