Environment-friendly cotton dyeing process based on fruit juice and environment-friendly cotton natural latex bra

Abstract

The invention discloses an environment-friendly cotton dyeing process based on fruit juice and an environment-friendly cotton natural latex bra, and relates to the technical field of printing and dyeing. The dyeing process comprises the following steps of S1, pretreatment; S2, dyeing; S3, washing and color fixing; and S4, drying and setting. During dyeing, fruit dye is adopted to dye an environment-friendly cotton fabric. The preparation process of the fruit dye comprises the following steps of A1, selecting fruits to be used, and cleaning the fruits; A2, crushing and grinding the fruits, adding water, performing mixing, controlling the temperature to be 50-80 DEG C, adding acetic acid for adjustment, controlling the temperature, and performing continuous stirring, wherein a mixture is vibrated through ultrasonic waves in the stirring process; and A3, filtering the mixture to obtain a filtrate and filter residues, and mixing the obtained filtrate with water to obtain the fruit dye. According to the invention, the cotton fabric is dyed based on the fruit juice dye, so that the pollution and harm caused by chemical dyeing are reduced, and the health and environmental friendliness of a bra fabric material are improved; and the dyeing effect of the fruit juice dye on the cotton fabric and the color fastness of the fabric are improved.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, more specifically, it relates to an environmentally friendly cotton dyeing process based on fruit juice and an environmentally friendly cotton natural latex bra. Background technique [0002] Dyeing is an important process in the production of textile fabrics. Through color matching, the colors people need can be printed and dyed into textiles, so that textiles have rich colors. The most traditional dyeing method is to extract natural plant dyes to obtain natural and environmentally friendly green dyes, and then dye the fabrics through traditional printing and dyeing processes, so that the printed and dyed fabrics are completely non-toxic and harmless, green and environmentally friendly, but traditional dyeing methods Most of them are efficient, and the dyeing effect is not good, which cannot meet people's needs for fabric color. [0003] With the development of the modern ch...

Problems solved by technology

As a traditional manufacturing country in my country, the textile printing and dyeing industry has also caused serious environmental pollution while promoting economic development. In the traditional dyeing process of pure cotton fabrics, a large number of corrosive and toxic chemicals are used to make pure cotton fabrics Contains residual formaldehyde, carcinogenic or allergenic prohibited azo dyes, heavy metal ions such as lead, chromium, pickaxe, diamond, mercury, etc., which endanger people's health during use, especially when used as underwear bras and close-fitting clothing. more serious effects on the user's body

[0004] In addition, a large amount of sewage produced in the process of chemical dyeing treatment has high chemical oxygen demand COD, which makes the treatment difficult and expensive, causing fatal salinization of the soil, causing land compaction, and causing serious harm to the environment. put a lot of pressure on the environment

[0005] In recent years, with the gradual improvement of people's awareness of environmental protection, there are few researches on the systematic development and utilization of natural dyes. Only some domestic textile printing and dyeing research institutes and some textile enterprises in the foreword have conducted research on natural plant dyes. New research and development have obtained certain theoretical research results, resulting in the fact that the current natural plant and fruit printing and dyeing technology is still immature, and the dyeing effect is unstable
