Abstract

The invention relates to the field of textile auxiliary agent, especially relates to a method for preparing a low temperature crosslinking resin for textiles. The method is carried out according to the following steps: mixing raw materials, stirring and controlling temperature, adding a monomer mixture, adding a monomer mixture and discharging. The method has high environmental performance, and can effectively save energy and achieve energy saving and environmental protection.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a method for preparing a low-temperature cross-linking resin used for textiles. Background technique [0002] Cross-linked resins are widely used in the finishing of fabrics such as stiffness, wrinkle resistance, and coating, among which it is particularly important for the stiffness finishing of curtain fabrics, luggage fabrics, and tent fabrics and the durable non-ironing finishing of cotton fabrics. At present, domestic resin finishing agents are mainly modified melamine resins and urea-formaldehyde resins, which have good stiffness and anti-wrinkle effects. However, this type of resin will release formaldehyde, which will seriously affect the physical and mental health of producers, users and consumers, and cause extremely adverse effects on the environment. [0003] As the international market has increasingly stringent environmental protection requirements for fabrics, i...
