Embodiment 1

[0030] 1. A printing darkening agent, characterized in that: said darkening agent is made up of the following raw materials in weight percent:

[0031]

[0032] The total amount of the above components is 100%. Through the affinity between the amino group in the A coupling agent and the additive and the amino group in the matrix, and the auxiliary agent 1006 active agent that acts as a crosslinking agent, the interface of the composite material has a relatively high Good adhesion, effectively improve the darkening effect of fabric dyeing.

[0033] The water mentioned above is deionized water or pure water softened in advance by a water softener to prevent the dye from forming metal dyes with calcium, magnesium ions and heavy metal ions such as copper and iron in the water, which will lose the dyeing ability and cause the color to fade. , the color fastness decreases;

[0034] The darkening agent and its finishing process are as follows:

[0035] S1. Arrange the embryos to...

Embodiment 2

[0044] Different from Embodiment 1, a printing darkening agent and its finishing process, the darkening agent is composed of the following raw materials in weight percentage:

[0045]

[0046]

[0047] The preparation and finishing process of the darkening agent are the same as those in Example 1.

Embodiment 3

[0049] Different from Embodiment 1, a printing darkening agent and its finishing process, the darkening agent is composed of the following raw materials in weight percentage:

[0050]

[0051] The preparation and finishing process of the darkening agent are the same as those in Example 1.

Abstract

The invention relates to the technical field of cloth printing, and discloses a printing darkening agent and its finishing process. The darkening agent is composed of the following raw materials in weight percentage: 15%-25% of 3A coupling agent, 15%-25% 25% high ammonia silicone oil 20%, 2% 1006 active agent, 2% AEO‑3, 2% polyetheramine, 2% glacial acetic acid and 42%‑62% water; darkening agent and its The finishing process is as follows. The printing deepening agent and its post-finishing process, through the affinity between the amino group in the A coupling agent and the additive and the amino group in the matrix, plus the auxiliary agent 1006 active agent that acts as a crosslinking agent, the interface of the composite material It has good adhesion and can effectively improve the fabric. 3A coupling agent, high ammonia-containing silicone oil, 1006 active agent, AEO-3, polyether amine, and glacial acetic acid are prepared in corresponding proportions to form a darkening agent, which makes the pigment It can save up to 20%, and the degree of color enhancement can be increased by up to 20%, which significantly improves the color enhancement effect of the cloth and saves the cost of dyes.

Description

technical field [0001] The invention relates to the field of cloth printing, in particular to a printing darkening agent and its finishing process. Background technique [0002] Cotton material is a kind of fabric produced by textile process with cotton as raw material. Adult cotton is usually 80% cotton and 20% polyester fabric. Adult cotton fabric generally needs to be printed to improve its appearance and give people a sense of comfort. Printing is the process of printing various colors and patterns on adult cotton fabrics with dyes or pigments. With the development of printing technology, darkening agents are added during the printing process to improve the dyeing performance of dyes. [0003] Darkening agent is an auxiliary agent used to increase the dyeing depth of disperse dyes in adult cotton printing. The function of the darkening agent used in the dyeing process is to modify the surface of adult cotton, thereby changing or improving the quality of adult cotton. Su...
