Embodiment Construction

[0028] In order to solve the above technical problems, the technical solutions of the present invention are implemented as follows.

[0029] (1) Pretreatment process of dipping Aifu wax:

[0030] Description of Aifu wax: Aifu wax imitation dyeing is similar to but different from the traditional batik process. In traditional batik, the parts of the fabric that need to show patterns are painted by hand, and then dyed. The painted parts have the anti-dyeing effect of wax, which makes it difficult for dyes to be dyed, so that the fabric will show its full color. Patterns are required, and cracks can also be generated by randomly folding and pressing the waxed parts before dyeing. During the dyeing process, as the dyed fabric is turned, cracks will also occur on the parts coated with wax, and the dye solution will flow smoothly. The cracks infiltrate into the fiber, and then after dyeing processes such as dewaxing, washing, soaping and drying, patterns and naturally formed ice pat...

Abstract

The invention relates to a method for distressed rapid dyeing of a wool sweater. The method comprises the following steps: (1) wax-dipping: weighing liquid Evo wax with the amount of 1.05-1.15 times of the wool sweater fabric weight, at the room temperature, soaking the wool sweater in the wax liquid, and repeatedly kneading and pressing until being uniform; and carrying out low temperature drying or natural drying; (2) dyeing: putting the wool sweater fabric after wax-dipping pretreatment and drying into a prepared dyeing bath; heating up to 75-80 DEG C at a speed of 3 DEG C / min, and holding for 5-10 min to achieve dyeing; (3) carrying out color fixation: after dyeing, adding a cationic color-fixing agent for color fixation for 5 min, and then taking out the fabric; (4) cleaning: washing with a non-ionic surfactant for 15 min at the temperature of 70 DEG C; and (5) drying. After the wool sweater is dyed by the rapid dyeing process, a distressed effect of distinct depth levels and uniform overall appearance appears. In addition, compared with a conventional dyeing process, the dyeing time is shortened by 60%-70%, and the color fastness is at the level of 2.5 or above.

Description

technical field [0001] The invention relates to a woolen sweater imitation process method, in particular to a woolen sweater imitation rapid dyeing method, which belongs to the technical field of dyeing and finishing. Background technique [0002] Wool knits are especially suitable for distressed styles. Because the floating line of the knitted fabric is longer, the weave points are prominent and eye-catching, and the effect of distressing is more visually layered and obvious. [0003] The more mature imitation techniques used on cotton fabrics include stone mill imitation, biological enzyme imitation, and bleach imitation. Obviously not suitable for woolen sweaters and cashmere sweaters. [0004] At present, some old-fashioned methods of wool knitting products are disclosed in the prior art. For example, the patent application number 200910186642 relates to an old-fashioned fog-like fabric, which is formed by interweaving warp yarns and weft yarns. The warp yarns are 50D ...
