Example Embodiment

[0023] Example 1

[0024] (1) Configure the surface modifier. In terms of weight percentage, mix 10% benzoyl chloride, 3% sodium hydroxide, 2% silicone emulsion, 25% diethylene glycol, and 60% tap water.

[0025] (2) Configure the solubilizer. Mix 50% glycerol and 50% tap water by weight percentage;

[0026] (3) Pretreatment and transfer printing, etc. The conventionally treated pure cotton fabric is treated with a surface modifier for two dipping and two rolling, with a dipping rate of 80%, drying at 60°C, and baking at 170°C for 100 seconds, then The solubilizer is subjected to one dip and one rolling, the residual rate is controlled to 80%, and the drying treatment is carried out at 70°C. Finally, the disperse yellow SE-3GE is used on the heat transfer printing machine to transfer printing and corresponding hot water washing at 250°C, 25s, 1.2amt , Soaping, hot water and cold water washing.

Abstract

The surface modifier for transfer printing with dispersive cotton fabric dye consists of bridging agent 10-40 wt%, pH regulator 0-5 wt%, modifier 0-5 wt%, swelling agent 5-30 wt%, and diluent for the rest. The present invention also discloses the cotton fabric pre-treating process before transfer printing with dispersive cotton fabric dye, and the process includes the first treating white cotton fabric with the surface modifier and the subsequent padding in solubilizer. The process is simple, and can result in printed fabric with bright color, high color fastness, good hand feeling, high hygroscopicity, high strength and no harm to human body.

Description

technical field [0001] The invention belongs to the technical field of a surface modifier for cotton fabric before printing and a pretreatment method for cotton fabric before printing, and in particular relates to a surface modifier for cotton fabric disperse dye transfer printing and a pretreatment method for cotton fabric before printing. Background technique [0002] Disperse dye thermal transfer printing technology for polyester fabrics is a method of contacting the fabric with transfer printing paper and hot pressing on a heat transfer machine. Transfer from printed paper to fabric (Wang Jusheng. Principles of Dyeing and Finishing Technology (Volume Three) [M]. Beijing: China Textile Press). Now someone applies this technology to pure cotton fabrics, but because there is no binding force between cotton fabrics and disperse dyes, it is necessary to modify the surface of pure cotton fabrics before printing. Common modifiers or methods for surface modification of pure cot...
