Problems solved by technology

However, during exhaust dyeing, due to the long dyeing time, reactive dyes are still easy to be dyed on the pattern part printed with the above-mentioned anti-dyeing agent, but the depth is shallow, and the ideal anti-dyeing effect cannot be achieved.
[0004] In addition, conventional cellulose fiber resist printing basically adopts the round / flat screen printing method. Due to the limitation of coarse mesh and large amount of sizing, it is difficult to achieve the fineness of the pattern in the round / flat screen printing method.

Embodiment 1）

[0022] This embodiment is the anti-dye printing process of cotton / spandex (95 / 5) twill, as follows:

[0023] ①Prepare 15g of sulfenic acid derivatives, 30g of fluorine-free water repellent Phobol RSH, 15g of polyethylene glycol binder and 40g of water to make a stain resist.

[0024] Get 20g of the above self-made anti-staining agent and 5g hydroxypropyl guar gum paste, 2g anionic penetrant sodium dodecylbenzenesulfonate, 0.5g non-silicon defoamer H-2300 and 72.5g water to prepare anti-staining agent Dyeing slurry.

[0025] ②Use gravure printing to print the resist slurry in step ① on cotton / spandex (95 / 5) twill fabric and dry it. The intaglio used is engraved with a Scottish pattern.

[0026] ③The cotton / spandex (95 / 5) twill fabric printed in step ② is dyed in the overflow tank according to the conventional dyeing process of reactive dyes, and black reactive dyes are used for dyeing. Yarn-dyed effect black and white Scotch pattern printed products, see the results figure ...

Embodiment 2）

[0028] This embodiment is basically the same as Embodiment 1, the difference is:

[0029] The denim pattern is engraved on the intaglio plate used in step ②, and the indigo blue reactive dye is used for dyeing in step ③, and finally a printed product with a denim-like pattern is obtained. The results are shown in figure 2 .

Abstract

The present invention relates to a resist printing technique for a cellulosic knitted good. The technique comprises: printing the cellulosic knitted good with a dye resist, followed by oven drying and then dyeing with a reactive dye. The dye resist is prepared using the following components at the corresponding mass percentages: 10-30% of an independently developed dye resist; 4.2-5.6% of a thickening paste; 1-3% of a penetrant; 0.1-1% of an anti-foaming agent; and the remainder of water. The independently developed dye resist is prepared using the following components at the respective mass percentages: 10-20% of a dye discharging agent; 20-40% of a fluoride-free water repellent; 10-20% of an adhesive; and 20-60% of water. When compared to a conventional reactive dye resist such as sodium hydroxymethylsulfinate, tin(II) chloride, and the like, the independently developed dye resist can generate an excellent white resist effect while ensuring uniform dyeing of the front and back surfaces of the cellulosic knitted good.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a dye-resistant printing process for cellulose fiber knitted fabrics. Background technique [0002] Resist printing is printing before the fabric is dyed (or not yet colored, or not yet fixed after dyeing). The printing paste contains a resist that can prevent the ground color dye from being dyed (or developed, fixed). , and then dyeing (or color development, color fixation) on the dyeing machine. Because of the anti-dyeing agent in the printing area, the ground color dye cannot be dyed (or developed or fixed), so the printed area still maintains a white ground. This is the anti-white anti-dye printing (referred to as anti-white). If at the same time, another type of dye that cannot be destroyed by the anti-dyeing agent is added to the printing paste, and the fiber is dyed after post-treatment, the pattern that is not covered by the ground color c...
