a slurry composition

Abstract

The invention discloses a sizing agent combination which comprises, by weight, 1-3 parts of thickener, 0.5-1.5 parts of crease-resistant agent, 2-4 parts of potato oxidized starch, 0.2-0.5 part of antifoaming agent, 0.5-1 part of leveling agent and 90-95 parts of water. By means of the synergistic effect of all the constituents, the water retention capacity and viscosity of the sizing agent combination are improved, and the dyeing effect of dye-based ink is good. Fabric subjected to digital printing by means of the sizing agent combination can be colored deeper and brighter, the color design is clear, and stain bleeding is avoided. Due to the adoption of the crease-resistant agent, the crease resistance of silk and wool blended fabric is improved greatly, the finishing process conducted after the silk and wool blended fabric is printed is omitted, and energy is saved. Due to the adoption of the antifoaming agent, even sizing is achieved by means of the sizing agent combination, no foam is generated, and the printing effect is improved.

Description

technical field [0001] The invention relates to a size composition which can be used for digital printing of silk and wool blended fabrics. Background technique [0002] Compared with traditional printing technology, digital inkjet printing technology has obvious advantages, no need for net making, low energy consumption, no waste, high precision, unlimited colors, wide application, and can adapt to the market demand of personalization, small batch and quick response . In recent years, digital inkjet printing technology has developed rapidly. [0003] The ingredients of digital printing slurry in the prior art include sodium alginate, modified starch, starch, synthetic paste, urea, sodium bicarbonate, ammonium sulfate and the like. The modified starch of the digital printing paste in the prior art mostly adopts wheat modified starch, corn modified starch, etc., which has poor water retention, poor dyeing effect of dye ink, poor coloring ability, light color yield, and uncl...

AI Technical Summary

Problems solved by technology

The modified starch of the digital printing slurry in the prior art mostly adopts wheat modified starch, corn modified starch, etc., which has poor water retention, poor dyeing effect of dye ink, poor coloring ability, light color yield, and unclear printing pattern

The price of synthetic paste is high, and after digital printing, the excess printing paste is not easy to clean, resulting in stiff printed fabric and poor hand feeling

[0004] The printing slurry in the prior art uses urea as a hygroscopic agent, and urea contains N elements, and the amount is relatively large, and the N elements in the waste water in the production process are likely to cause eutrophication of the water body and lead to algal blooms, which cause great environmental pollution; and Using urea as a hygroscopic agent is prone to bleeding and the printing pattern is not clear

[0005] No antifoaming agent is added to the printing paste in the prior art, resulting in uneven sizing and generation of air bubbles, resulting in poor printing effect

[0006] The anti-wrinkle performance of silk-wool blended fabric is poor, and it consumes water and energy for finishing alone. The digital printing slurry used in the prior art is used to print silk-wool blended fabric, and the color light of digital printing is not bright

Existing digital printing pastes have no effect on improving the wrinkle resistance of silk-wool blended fabrics
