Technical Field

The invention relates to the field of textile dyeing and finishing soaping process, in particular to a polyester terylene anti-sticking soaping agent and a preparation method thereof.

Background

The terylene disperse printing is the most common one in the prior printing fabrics, and has higher market recognition degree due to bright color light, excellent color fastness and good drapability. The production process of the polyester printed fabric comprises four steps of color sizing, baking, soaping and after-finishing, wherein the soaping is the most critical ring for determining the product quality.

The conventional soaping process of the polyester printed fabric is reduction cleaning, and the purpose of removing floating color is achieved by structurally damaging dispersed floating color through sodium hydrosulfite under an alkaline condition. However, the sodium hydrosulfite has great potential safety hazard in the storage process and can generate strong pungent peculiar smell in the use process.

In the industry, a soaping agent replacing sodium hydrosulfite appears, and thiourea is mainly used as a reduction main body and is compounded with sodium dodecyl benzene sulfonate. Although the storage safety of the prepared soaping agent is higher than that of the sodium hydrosulfite, the reduction efficiency of the soaping agent is far lower than that of the sodium hydrosulfite due to shorter washing time in the open-width soaping process of the polyester printed fabric. In addition, thiourea is a reductive substance, and still generates sulfur-containing irritant gas after being heated and moistened, so that the safety of storage and use cannot be fundamentally avoided. The added sodium alkyl sulfonate and ethylene oxide condensate only have a dispersing effect on the slurry and cannot directly act on dispersed floating color, and the surface active foam is large, so that the water cost in the reduction cleaning process is increased.

Disclosure of Invention

The invention aims to provide a polyester terylene anti-staining soaping agent and a preparation method thereof, which are used for solving the problems that the soaping agent in the prior art can emit irritant gas, is unsafe to use, has low reduction and cleaning efficiency, high cost and the like.

Further, the plant polyphenol is cashew bisphenol block polyether, and the general structural formula of the plant polyphenol is as follows:

Wherein a + b + c + d in the structural general formula is 15-30.
