Problems solved by technology

This type of anti-wrinkle finishing agent has a good anti-wrinkle effect, but there is a problem of releasing formaldehyde during production and consumption, which limits the promotion and application of this type of finishing agent
In recent years, anti-wrinkle finishing agents such as polycarboxylic acids, acetals, polyurethanes, and epoxy resins have been developed. Although they solve the problem of releasing formaldehyde, due to their complex synthesis process, they are expensive and the finishing effect is not as good as N-methylol finishing agent
In addition, due to the existence of a large number of rigid crosslinks, the strength loss of the fabric is serious and accompanied by yellowing

Abstract

The invention discloses a hyperbranched anti-crease finishing agent as well as a preparation method and an application thereof and belongs to the field of textile printing and dyeing. A hydrophobic monomer and a monomer containing adjacent carboxylic groups are taken as comonomers, a branched macromolecule is polymerized under the action of an initiator and a branched monomer, a reactive group is introduced to the structure of the branched macromolecule, and the anti-crease finishing agent is synthesized. According to the preparation method and the application, conditions are mild, and the operation is simple and convenient. The anti-crease finishing agent has excellent performance, formaldehyde is not released in production and application processes, a phosphorus-containing catalyst is not needed to add or only a minute quantity of the phosphorus-containing catalyst is needed to add, and the environment is protected.

Description

technical field [0001] The invention relates to a hyperbranched anti-wrinkle finishing agent and its preparation method and application, belonging to the field of textile printing and dyeing. Background technique [0002] Cotton fiber fabric has the advantages of moisture absorption, breathability, antistatic, comfortable to wear, economical and affordable, etc., and is deeply loved by people. However, pure cotton fabrics also have disadvantages such as poor elasticity and easy wrinkling. In order to improve the wrinkle resistance of fabrics, anti-wrinkle finishing is often carried out in the dyeing and finishing of cotton fabrics. For a long time, the anti-wrinkle finishing of cotton fabrics has been a hot topic of research by scientific and technological workers. At present, amide-formaldehyde finishing agents are widely used, especially N-methylol amide compounds, such as dimethylol dihydroxyethylene urea (DMDHEU referred to as 2D resin). This kind of anti-wrinkle fini...
