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 fabric printing, and discloses a printing deepening agent and a post-finishing process thereof. The deepening agent is prepared from, by weight, 15-25%of a 3A coupling agent, 15-25% of high ammonia-containing silicone oil, 2% of a 1006 active agent, 2% of AEO-3, 2% of polyether amine, 2% of glacial acetic acid and 42-62% of water. The deepening agent and the post-finishing process are as follows. According to the printing deepening agent and the post-finishing process thereof, through amino groups in the A coupling agent, an additive and amino groups in a matrix have affinity, and then the auxiliary 1006 active agent is added, so that the interface of a composite material has better adhesiveness, which effectively improves a fabric; the 3A coupling agent, the high ammonia-containing silicone oil, the 1006 active agent, the AEO-3, the polyether amine and the glacial acetic acid are prepared into the deepening agent according to a corresponding proportion, so that a pigment is saved by 20% at most, the deepening degree of the color is improved by 20% at most, the cloth coloring effect is significantly improved, and the dye cost is also reduced.

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...
