Problems solved by technology

In the water washing process, sand blasting has been banned in foreign countries, because workers who perform sand blasting operations cannot get safe protection and are prone to silicosis
The washing process requires the use of hundreds of toxic chemicals to bleach and wash jeans, and the chemicals left on the jeans are likely to affect the wearer's health

Embodiment 1

[0043] The washing-free production process of jeans comprises the following steps:

[0044] (1) Sizing: soak the white gray cloth with slurry at a temperature of 60°C for 30 minutes, and then dry it at 100°C;

[0045] (2) Printing: Print the designed pattern with digital inkjet printing. Digital inkjet printing is to input the image processed by digital technology into the computer, edit and process it through the computer printing color separation system (CAD), and then use the special software (RIP). Control the printing system to directly spray the reactive dye gravure ink onto the PET film to form a pattern to make a transfer printing PET film; then send the sized white gray cloth and the transfer printing PET film to the paddle car for pressure at the same time, and the temperature is 160°C , the time is 3 minutes, and the printed pattern is obtained on the white gray cloth after sizing;

[0046] (3) Steaming: steaming temperature 100°C, time 8 minutes;

[0047] (4) Cut...

Embodiment 2

[0057] Jeans are prepared according to the jeans wash-free production process and raw material ratio of Example 1, the difference is only that the reactive dye gravure ink is prepared from the following raw materials in percentage by weight: 30% of K-type reactive dye, carboxymethyl starch Sodium 24%, ethanol 15%, polydimethylsiloxane 0.4%, deionized water 30.6%, obtain the jeans of embodiment 2.

Embodiment 3

[0059] Prepare jeans according to the jeans wash-free production process and raw material ratio of Example 1, the only difference is that the reactive dye gravure ink is prepared from the following raw materials in percentage by weight: 30% K-type reactive dye, hydroxyethyl starch 24%, ethanol 15%, polydimethylsiloxane 0.4%, deionized water 30.6%, obtain the jeans of embodiment 3.

Abstract

The invention discloses a wash-free production process for jeans. The wash-free production process for the jeans comprises the following steps: (1) sizing; (2) printing; (3) steaming; (4) tailoring; (5) sewing; and (6) performing afterfinish. The wash-free production process for the jeans disclosed by the invention combines the modern computer technology, the chemical technology, the mechanical automation technology, the printing technology and the like perfectly, and has the following three advantages that the cost is low, and the produced jeans are 5 to 20 yuan unequally cheaper than those produced by the conventional method; the quality is high, the used dye is activated dye, the color fastness reaches level 4 and higher than that of the indigo and sulfur dye, and the jeans are water washing resistant and colorfast and look new for a long time; and the pollution is low, the water consumption is low, and particularly the jeans are not required to be subjected to color stripping treatment by using a large amount of heavy metal compounds of lead, cadmium and the like and nonyl phenol, octyl phenol, perfluorooctane sulphonate, benzidine, formaldehyde and the like in the prior art.

Description

technical field [0001] The invention relates to the field of clothing, in particular to a wash-free production process for jeans. Background technique [0002] Jeans originated in the United States and have been popular in the American market for nearly a hundred years. In the early days, jeans were just a kind of rough and durable work clothes, and they have never been in the elegant hall because they have nothing to do with the word "fashion". Until the past 20 to 30 years, through continuous efforts to improve and innovate in the spinning, weaving and dyeing industries, jeans have changed from rough and simple to a variety of weaving, color and style, making it from a common single type of trousers. Create a variety of unique styles, coupled with the refreshing changes in other distinctive accessories, so jeans have gradually evolved into a unique category of fashion, which is very popular among young men and women. [0003] The production and sewing of jeans generally ...
