Problems solved by technology

However, chitosan cannot be directly dissolved in water, but can only be dissolved in some organic acids and inorganic acids, so it is not conducive to the cleaning and removal of the paste after printing and steaming, and it will make the fabric feel hard

Abstract

The invention discloses acidic ink digital printing anti-bleeding size for a woolen fabric. The anti-bleeding size is prepared from 0.5%-3% of modified starch, 2%-5% of a cosolvent, 1%-3% of glycerin, 1%-2% of anhydrous sodium sulphate, 1.5%-2.5% of ammonium sulfate, 0.2%-1.4% of a thickening agent, an acidity pH value regulator and the balance water, wherein the pH value of the anti-bleeding size is 4-5, and the thickening agent is selected from at least one of konjac glucomannan, xanthan gum, guar gum and carrageenan. According to the acidic ink digital printing anti-bleeding size for the woolen fabric, chitosan in the prior art is replaced with the water-soluble thickening agent, the characteristics of being hydrophilic, capable of forming a film and high in stability of konjac glucomannan, xanthan gum, guar gum, carrageenan and the like are utilized, paste materials in the fabric which is pretreated by the pretreating size, subjected to digital printing and steamed are easy to wash and remove, and the fabric free of residual paste materials is soft in handfeel.

Description

technical field [0001] The invention relates to the technical field of textile production, in particular to an anti-seepage slurry for acid ink digital printing of woolen fabrics. Background technique [0002] Worsted woolen fabrics have a smooth, waxy and delicate feel, soft luster, excellent texture, and noble colors after dyeing or printing, and are favored by consumers. Digital inkjet printing has good effects and is green and environmentally friendly. Therefore, it has developed rapidly in the textile printing industry and has been widely used in the printing of cashmere, wool, silk and other high-end fabrics. However, in the actual production of cashmere digital printing, there are still a series of problems such as serious dye bleeding, insufficient clarity and fineness of patterns, low vividness and low color yield. The improved technical scheme adds chitosan to the slurry, and utilizes the electrostatic attraction and antibacterial properties of chitosan to the woo...
