Embodiment 1

[0069] This embodiment provides a fabric dyeing process. The fabric is a denim fabric: the warp and weft yarns are all made of Taiwan Sanyong OE10, and the fabric structure is 3 / 1 right diagonal. The dyeing process steps are as follows:

[0070] (1) Singeing: Use a singeing machine to singe the fabric at a speed of 65m / min, and use two positive and one negative singeing ports;

[0071] (2) Desizing: The desizing process selects the cold pad-batch process, and the process is as follows: the concentration of desizing enzyme (high-temperature-resistant α-amylase, purchased from Baxter Biotechnology Co., Ltd.) in the desizing solution is 15g / L, silicon Sodium acid concentration is 3g / L, hydrogen peroxide (mass concentration: 30%) concentration is 23g / L, OK oil concentration is 12g / L, M oil concentration is 3g / L; temperature is 70°C, vehicle speed is 65m / min, stacked for 24h;

[0072] (3) Ozone steaming and washing: the fabric after cold pad batching is subjected to ozone steaming...

Embodiment 2

[0078] This embodiment provides a fabric dyeing process, the fabric is a denim fabric: the warp and weft yarns are respectively made of Tianhong Yinlong organic cotton 21 and Tianhong Yinlong organic cotton 21 / 70-3.5 spandex, and the fabric structure adopts 3 / 1 right diagonal . The dyeing process steps are as follows:

[0079] (1) Singeing: Use a singeing machine to singe the fabric at a speed of 65m / min, and use two positive and one negative singeing ports;

[0080] (2) Desizing: the desizing process selects the cold pad batch process, and the process is: pH is 6.0, and the concentration of desizing enzyme (high temperature resistant type α-amylase, purchased from Pasteur Biotechnology Co., Ltd.) in the desizing solution is 15g / L, the concentration of sodium silicate is 3g / L, the concentration of hydrogen peroxide (mass concentration 30%) is 23g / L, the concentration of OK oil is 10g / L, and the concentration of M oil is 3g / L; Set 23h;

[0081] (3) Ozone steaming and washin...

Embodiment 3

[0087] This embodiment is a fabric dyeing process, the fabric and dyeing process steps are the same as those in Example 1, the main difference is that the desizing process is different, and the mercerizing process is not performed.

[0088] Specific steps are as follows:

[0089] (1) Singeing: Use a singeing machine to singe the fabric at a speed of 65m / min, and use two positive and one negative singeing ports;

[0090] (2) Desizing: the desizing process adopts the alkali desizing process, and the process is: the concentration of caustic soda in the desizing solution is 15g / L, the concentration of OK oil is 3g / L; the temperature is 70°C, the speed is 65m / min, and the stacking is 18h;

[0091] (3) Ozone steaming and washing: the fabric after cold pad batching is subjected to ozone steaming and washing, and the ozone density is 10g / m 3 , steaming temperature 105 ℃, wherein oxygen bleaching formula is: hydrogen peroxide (mass concentration 30%) concentration 10g / L, OK oil concen...

Abstract

The invention relates to a dyeing process of a fabric. The dyeing process comprises the following steps: the fabric is padded in a dye bath, wherein the dye in the dye bath comprises vat dye leuco body salt; the fabric subjected to padding dyeing bath is subjected to steaming treatment and then is oxidized through an ozone box, the speed is 20-40 m / min, and the density of ozone in the ozone box is 10-20 g / m < 3 >; and the oxidized fabric are washed and arranged. According to the fabric dyeing process, ozone is used as an oxidizing agent, and dyeing defects can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of dyeing and finishing, in particular to a fabric dyeing process. Background technique [0002] Sulfur dyes and vat dyes are water-insoluble dyes, which are difficult to react with cotton fibers. Therefore, in practical applications, most of the leuco salts of dyes that have affinity for cellulose fibers are used to react with them, and then further dyeing is achieved through oxidation reactions. Traditional oxidation methods mostly use air oxidation and oxidant oxidation for color development. Among them, the air oxidation method has a longer oxidation cycle, so it needs more space for mass production, and the production cycle is long; the oxidant oxidation color is darker, but it has high requirements for operation and process control, such as the difference in product rolling rate. That is to say, it will have a certain impact on the depth and uniformity of the color of the fabric, and it is easy to ca...
