Problems solved by technology

[0003] However, the color fastness to industrial washing of the fabrics treated by this process is not very good, high salt is not conducive to clean production, and the fastness is low, especially for dark pure cotton fabrics, it is difficult to achieve more than 30 industrial washings without fading. The color fastness does not meet the requirements at all. In

Embodiment Construction

[0044] The technical solution of the present invention will be described in detail below in conjunction with specific embodiments.

[0045] Fabric: C16X12 108X56 57 / 8″

[0046] Dye prescription: black

[0047] Reactive black W-G 77.6g / L

[0048] Navy GG 2.4g / L

[0049] Mixed alkali agent: 40-42°Be water glass 50ml / L (65g / L)

[0050] Caustic soda (400g / L) 15ml / L

[0051] Process flow:

[0052] (1) Rolling material: Prepare alkali and reactive dyes separately at a temperature of 23°C, and then mix them by a proportional pump at a ratio of 4:1 and inject them into the rolling tank. The temperature of the tank dyeing solution is 25°C. Semi-finished products For rolling, one dip and one rolling method is adopted, and the rolling residual rate is 65%;

[0053] (2) Rolling: After leaving the rolling car, roll it on the glass rod for rolling, change the roll after 40 minutes, and then wrap the plastic film;

[0054] (3) Stacking: rotating speed is 8 rpm, stacking temperature is 29℃, stacking for 12...

Abstract

The invention relates to a dyeing and finishing processing method in the printing and dyeing production field, in particular to a dyeing and finishing process of washing colorfastness for a plurality of times of a deep color pure cotton fabric. The process comprises the following steps: carrying out reactive dyeing on the pure cotton fabric by a cold pad-batch color-fixing method by stacking under normal temperature, selecting a reactive dye for cold pad-batch dyeing so as to improve the fixation rate and properties such as compatibility, levelling property, alkali resistance and the like, padding a washing colorfastness promoter, and optimizing the cold pad-batch dyeing process to meet the requirement that the fabric has the washing colorfastness for a plurality of times.

Description

Technical field [0001] The invention relates to a dyeing and finishing process in the field of textile printing and dyeing production, in particular to a dyeing and finishing process for the color fastness of dark pure cotton fabrics to multiple washings. Background technique [0002] For the dyeing and finishing of pure cotton fabrics, the long-car continuous pad dyeing process is often used. The process steps are: turning the seam, then singeing, which requires one positive and one reverse, then desizing, washing, drying, mercerizing, and then rolling Material, drying, and then alkali fixation, soaping, water washing, drying, stenting, finishing and packaging to obtain the product. [0003] However, the industrial washing color fastness of fabrics treated by this process is not very good. High salt is not conducive to clean production, and the fastness is low. Especially for dark cotton fabrics, it is difficult to achieve more than 30 times of industrial washing without fading. ...
