Embodiment Construction

[0014] A polyester fabric direct-injection digital printing pretreatment slurry, its basic composition and mass percentage are:

[0015] Urea 7%

[0016] Sodium Alginate 2%

[0017] Sodium Carboxymethyl Cellulose 1%

[0018] Hexanol 0.5%

[0019] Glycerin 1%

[0020] Water 88.5%

[0021] If 1000g of slurry needs to be prepared, 70g of urea, 20g of sodium alginate, 10g of sodium carboxymethylcellulose, 5g of hexanol, 1g of glycerin and 885g of water are evenly stirred.

Abstract

The invention discloses a direct injection digital printing pretreatment slurry for dacron fabric; the pretreatment slurry consists of urea, sodium alginate, sodium carboxymethylcellulose, ethanol, glycerol and water. Through pre-treating and digital-printing by using the slurry, the color yield is high, the pattern is clear, the thickening rheological property of thickener is excellent and the lag thixotropy is relatively low.

Description

technical field [0001] The invention relates to a slurry, in particular to a polyester fabric direct-injection digital printing pretreatment slurry. Background technique [0002] It is currently used in the pretreatment of direct-injection digital printing of polyester fabrics. After digital printing, the color yield is low, the pattern is not clear, the rheology of the paste is poor, and the hysteresis thixotropy is relatively large. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a polyester fabric direct-injection digital printing pretreatment slurry, which is used for the direct-injection digital printing pretreatment of polyester fabrics. [0004] In order to achieve the above-mentioned technical purpose and achieve the above-mentioned technical effect, the present invention is realized through the following technical solutions: [0005] A polyester fabric direct-injection digital printing pretreatment slurry, ...
