Problems solved by technology

Although the cotton fabric obtained by treating with this modifier can obtain a satisfactory color depth during printing, it is easy to cause the fabric to feel hard, and the water absorption and air permeability are reduced; (2) use acetylated cellulose or directly acetylate the cotton fabric. Chemical grafting modification (Chen Qihong, Mi Qinghua. Discussion on thermal transfer printing process of cotton fabrics [J]. Journal of Wuhan Textile Engineering Institute, 1997 (10), 2, 12-17; Fan Xuerong, Zhang Haiquan. Heat transfer printing of pure cotton knitted fabrics Research on Transfer Printing [J]. Printing and Dyeing, 1996(22), 1, 14~17)
Although the cotton fabrics treated by these two methods do not lose much of their excellent properties, the printed fabrics obtained after printing are dull in color, and their strength and color fastness are greatly reduced.

Embodiment 1

[0024] (1) Configure the surface modifier by weight percentage, mix 10% benzoyl chloride, 3% sodium hydroxide, 2% organic silicon emulsion, 25% diethylene glycol, and 60% tap water to mix evenly;

[0025] (2) configure solubilizing agent by weight percentage, stir and mix 50% glycerin and 50% tap water;

[0026] (3) Pretreatment and transfer printing, etc. The conventionally treated pure cotton fabric is first dipped and rolled twice with a surface modifier, the excess rate is controlled at 80%, dried at 60°C, baked at 170°C for 100 seconds, and then The solubilizer is dipped and rolled, the excess rate is controlled to 80%, and it is dried at 70°C. Finally, it is transferred to the thermal transfer printing machine with disperse yellow SE-3GE at 250°C, 25s, 1.2amt, and corresponding hot water washing , soaping, hot water washing and cold water washing and other washing treatments are sufficient.

Embodiment 2

[0028] (1) configure surface modifier by weight percentage, with benzoyl thioglycolate sodium 25%, sodium carbonate 2.5%, baking soda 1%, anionic softener WML2%, anionic softener stasoft 747 1%, poly Ethylene glycol (molecular weight 400) 15%, distilled water 53.5%, stir and mix evenly;

[0029] (2) configure the solubilizing agent by weight percentage, mix 35% polyethylene glycol (polyethylene glycol) (molecular weight 200) 5%, and distilled water 60% to mix evenly;

[0030] (3) Pretreatment and transfer printing, etc. The conventionally treated pure cotton fabric is first dipped and rolled twice with a surface modifier, the excess rate is controlled at 82%, dried at 63°C, baked at 175°C for 100 seconds, and then The solubilizer is subjected to two-dipping and two-rolling, and the excess rate is controlled to 82%, and it is dried at 70°C. Finally, the disperse yellow SE-3GE is used on the thermal transfer printing machine, and the transfer printing and corresponding hot water...

Embodiment 3

[0032] (1) configure surface modifier by weight percentage, sodium benzoylsalicylate 25%, soda 3%, sodium hydroxide 1%, sodium dihydrogen phosphate 1%, nonionic softener FD-200 2% , glycerol 5%, polyethylene glycol (molecular weight 600) 10%, deionized water 53% stir and mix evenly;

[0033] (2) configure solubilizing agent by weight percentage, polyethylene glycol (molecular weight 200) 25%, deionized water 75% stir and mix evenly;

[0034] (3) Pretreatment and transfer printing, etc. The conventionally treated pure cotton fabric is first three-dipped and three-rolled with a surface modifier, the excess rate is controlled at 83%, dried at 67°C, baked at 180°C for 95 seconds, and then processed. The solubilizer is dipped and rolled, the excess rate is controlled to 83%, and it is dried at 68°C. Finally, it is transferred to the thermal transfer printing machine with Disperse Red E-4B at 250°C, 25s, 1.2amt, and the corresponding hot water washing , soaping, hot water washing a...

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...
