Problems solved by technology

[0002] Tie-dyeing is a traditional and unique dyeing process in my country. It is a dyeing method in which fabrics are partially tied up during dyeing so that they cannot be colored. Conventional tie-dyeing is dyed after folding needles and threads into a certain pattern. Manual needlework sewing is cumbersome. It is labor-intensive, and there are many pinholes in graphic fabrics after dyeing, especially in dense materials, the pinholes are more obvious and form small holes, which affects the appearance of the fabric surface, as shown in Figure 1

Embodiment 1

[0038] A tie-dyeing method, comprising the steps of:

[0039] (1) Fold the fabric to be dyed into a long strip according to the parallel direction by adopting the screen folding method (see figure 2 ), the above screen folding method is to fold the cloth into screen pleats in parallel or diagonal directions;

[0040] (2) Select the household bamboo mat block (dyeing part) of 2.5 * 1.3 * 0.3CM size for use, and the bamboo mat block is bundled on the fabric to be dyed after described step (1) folding at intervals and positioned (see image 3 ), get fabric 1;

[0041] (3) fabric 1 is placed in the dye vat, add medium temperature type reactive dyes (reactive red Remazol-Red3BS of DyStar company, active yellow Remazol-Yellow 3RS and active blue Levafix-Blue CA), OWF value is 3%, heat up Keep warm for 10 minutes after reaching 50°C, slowly add 30g / l of sodium sulfate to promote dyeing, heat up to 65°C and keep warm for 40 minutes, the bath ratio of the above active dyeing process...

Embodiment 2

[0045] A tie-dyeing method, in its steps and raw materials, except that the amount of the following raw materials is different: the OWF value of reactive dyes is 4%, the amount of sodium sulfate is 50g / l, and the amount of soda ash is 20g / l. The addition amount of soaping agent once is 2g / l and the addition amount of soaping agent for the second time is 1g / l, all the other are the same as embodiment 1.

Embodiment 3

[0047] A tie-dyeing method, in its steps and raw materials, except that the amount of the following raw materials is different: the OWF value of reactive dyes is 3.5%, the amount of sodium sulfate is 40g / l, and the amount of soda ash is 18g / l. The addition amount of soaping agent for the first time is 1.5g / l and the addition amount of soaping agent for the second time is 0.8g / l, all the other are the same as embodiment 1.

Abstract

The invention discloses a tie-dyeing method, which comprises the following steps: (1) folding the fabric to be dyed according to the requirements of the production pattern; (2) making dyed parts according to the requirements of the production pattern, and binding the dyed parts in the step ( 1) positioning on the folded fabric to be dyed to obtain fabric 1; (3) performing active dyeing on the fabric 1, adding alkali to fix the color, and washing it with normal temperature water to obtain fabric 2; (4) removing the fabric 2 The above-mentioned dyed parts are soaped twice, washed with water, neutralized with acid, and dried. In order to overcome the disadvantages of cumbersome tie-dyeing and many pinholes affecting the appearance of the prior art, the present invention adopts the method of folding the fabric according to the production requirements and then quickly binding it with dyed parts, and cooperates with the preferred tie-dyeing process steps and parameters to obtain the final product. The pattern of the product is lively and natural, the cloth surface is complete and beautiful.

Description

technical field [0001] The invention relates to the field of tie-dyeing, in particular to a tie-dyeing method. Background technique [0002] Tie-dyeing is a traditional and unique dyeing process in my country. It is a dyeing method in which fabrics are partially tied up during dyeing so that they cannot be colored. Conventional tie-dyeing is dyeing after folding needles and threads into a certain pattern. Manual needlework sewing is cumbersome. It is labor-intensive, and there are many pinholes in graphic fabrics after dyeing, especially the pinholes of dense materials are more obvious and form small holes, which affects the appearance of the fabric surface, as shown in Figure 1. Contents of the invention [0003] Based on this, it is necessary to provide a novel tie-dyeing method for the problems referred to above. [0004] For realizing above-mentioned technical purpose, technical scheme is as follows: [0005] A tie-dyeing method, comprising the steps of: [0006] (1)...
