Abstract

The invention relates to the technical field of novel material research, development and preparation and discloses a dyeing accelerant capable of improving dyeing performance of cotton fabrics. The prepared dyeing accelerant is added into reactive dye diluent to realize dyeing treatment of the cotton fabrics and capable of reducing surface tension of wood in contact with dyes; the dyeing accelerant is high in chemical activity and capable of increasing the degree of freedom of active groups in dye molecules, reducing electrostatic repulsive force and promoting reactive dyes and cotton fabric fibers to form reaction covalent bonds; high leveling performance is achieved, dye hue can be kept, prominent light stability and heat stability are achieved after dyeing, color brightness is guaranteed, and excellent light fastness, fastness to wet rubbing and fastness to sunlight are achieved; besides, water resistance of dyes can be improved, and high fastness to washing and scrubbing is realized.

Description

technical field

[0001] The invention belongs to the technical field of research and development and preparation of new materials, and in particular relates to a dyeing accelerator for improving the dyeing performance of cotton fabrics. Background technique

[0002] With the improvement of people's living standards, more and more attention is paid to the quality of clothing materials, and cotton fabric products on the market have always been one of the most popular choices; cotton fabric, also known as cotton cloth, is a fabric woven from cotton yarn . Cotton fabric has become one of the most commonly used fabrics due to its excellent wearability, and is widely used in clothing fabrics, decorative fabrics and industrial fabrics. Cotton is the most popular clothing and home textile fabric. Versatile, soft, breathable, moisture-wicking, year-round comfort, performance, and durability are just a few of the many qualities that make cotton cloth so popular.

[0003] Due to the ...
