Environmental protection type dye printing paste without steaming and washing

Abstract

The invention discloses an environment-friendly steam-/wash-free dye printing paste, which is implemented by re-formulating monomer components partially in the prior binder. The steam-/wash-free binder can meet the requirement of random combination with acidic dyes, active dyes and disperse dyes; and is suitable for both manual and mechanical printing. The product printed with the blend of synthetic steam-/wash-free binder has bright color, clear pattern, high color yield, uniform printing block, good flowability, and soft touch. The invention is suitable for various printing processes such as direct printing, discharge printing and burnt-out printing, and is also used for printing various textile fabrics after mixing with other dyes. The invention simplifies the printing process, solves the environmental problem of the prior printing process, and avoids the environmental pollution of waste water.

Description

technical field [0001] The invention relates to an environment-friendly non-steaming and non-cleaning slurry for dye printing. Background technique [0002] Dye printing has been following the traditional process of screen printing-steaming (hair color)-washing (washing off floating color and paste residue)-drying and finalizing the finished product for many years, and the sewage discharge after washing has directly caused damage to pollution of the environment. [0003] It is undeniable that the textile printing and dyeing industry in many countries is still a major polluter so far, which has restricted the expansion of consumption of textile products to a large extent, and has also greatly hindered the sustainable development of the textile printing and dyeing industry. So far, it has not been able to fundamentally solve. [0004] So far, commonly used general dye printing is mainly based on paste, sodium naphthalate and synthetic modifiers, pigment printing can use adhe...

[0003] It is undeniable that the textile printing and dyeing industry in many countries is still a major polluter so far, which has restricted the expansion of consumption of textile products to a large extent, and has also greatly hindered the sustainable development of the textile printing and dyeing industry. So far, it has not been able to fundamentally solve

[0004] So far, commonly used general dye printing is mainly based on paste, sodium naphthalate and synthetic modifiers, pigment printing can use adhesives, and due to the different types, properties and cracks of dyes, it is now used for coating types When the adhesive is mixed with direct and acid dyes, reactive dyes, and disperse dyes, it often appears: 1. Hydrolysis; 2. Coagulation; 3. Layering; basically cannot be directly used for screen printing
