Embodiment 1

[0036]This embodiment proposes a kind of preparation method of denim fabric, adopts cotton fiber to make described denim fabric after oxygen bleaching, dyeing, spinning, weaving, washing, and this dyeing comprises the following steps:

[0037] (1) Pretreatment: Make the cotton fiber after oxygen bleaching into a silk cake and put it into the dyeing vat, control the amount of cotton fiber and water according to the bath ratio of 1:5, and add additives to it;

[0038] (2) Dyeing: Add dye, sodium sulfate and alkali to the tank to dye the cotton fiber;

[0039] (3) Post-treatment: dyed cotton fibers are treated with oil to obtain dyed fiber products.

Embodiment 2

[0041] This embodiment proposes a kind of preparation method of denim fabric, adopts cotton fiber to make described denim fabric after oxygen bleaching, dyeing, spinning, weaving, washing, and this dyeing comprises the following steps:

[0042] (1) Pretreatment: make the cotton fiber after oxygen bleaching into a silk cake and put it into the dyeing vat, control the amount of the cotton fiber and water according to the bath ratio of 1:12, and add additives to it;

[0043] (2) Dyeing: Add dye, sodium sulfate and alkali to the tank to dye the cotton fiber;

[0044] (3) Post-treatment: dyed cotton fibers are treated with oil to obtain dyed fiber products.

Embodiment 3

[0046] This example proposes a preparation method of a denim fabric, which uses cotton fibers to undergo oxygen bleaching, dyeing, spinning, weaving, and washing to prepare the denim fabric.

[0047] In the above process, oxygen bleaching is to control the amount of cotton fiber and water according to the bath ratio of 1:6, and add hydrogen peroxide, hydrogen peroxide stabilizer, penetrant and scouring enzyme to it in order to control the concentration of hydrogen peroxide, hydrogen peroxide stabilizer and penetrant in the bath. The concentration of scouring enzyme and scouring enzyme is 26g / L, 1g / L, 1g / L, 1g / L in turn, heat to 85°C, keep warm for 60min, then add glacial acetic acid to it, after adding glacial acetic acid, the glacial acetic acid in the bath The concentration is 0.3g / L, the temperature is controlled at 30°C, and the temperature is kept for 50 minutes to complete the oxygen bleaching process.

[0048] Staining involves the following steps:

[0049] (1) Pretrea...

Abstract

The invention discloses a method for preparing a jean fabric. The method comprises the following steps: performing oxygen bleaching, dyeing, spinning, weaving and washing on cotton fibers, thereby obtaining the jean fabric, wherein the dyeing step comprises pre-treating, dyeing and performing after-treatment, thereby obtaining the dyed fiber product. According to the method disclosed by the invention, the cotton fibers serve as raw materials, the cotton fibers subjected to oxygen bleaching are dyed, spun and woven so as to obtain the jean fabric, the problems of the existing jean fabrics such as great waste, environmental pollution, extremely low accepted rate, high labor intensity, low color fastness and poor dyeing operating environment in the operating process of dyeing spun yarns or dyeing woven fabrics are solved, the problems that the jean fabric is low in yield, environmental protection does not reach the standard and the like are solved, and the method is suitable for wide popularization and application.

Description

technical field [0001] The invention relates to a method for preparing a denim fabric, in particular to a new method for preparing a denim fabric with cotton fibers, which belongs to the field of denim textiles. Background technique [0002] Traditional denim fabrics are made from pure cotton through spinning, dyeing, sizing, weaving and finishing. In order to improve the performance of denim fabrics, in the current denim market, there are also a series of blended fabrics, such as cotton / polyester (50 / 50) blended fabrics, and cotton and other fibers such as Tencel, linen, or even jute, wool Yarn and other fibers are woven together, which expands the categories and special requirements of denim fabrics, and develops special non-cotton denim fabrics with denim style. Such as patent documents CN105803761A (a production process of colored soft denim, 2016.07.27, D06M11 / 50), CN105200625A (a production method of micro-elastic denim imitation fabric, 2015.12.30, D03D15 / 00), etc. ...
