Problems solved by technology

[0002] Although the fibers and fabrics have relatively bright colors after dyeing, they are prone to fading and staining when washing. This is because some dyes have soluble groups on them, which make their fastness poor. Makes itself look old, and the faded color will stain other fabrics, which is very inconvenient

Abstract

The invention discloses a fabric formaldehyde-free fixing agent. The fixing agent comprises the following raw materials in parts by mass: 10-15 parts of poly dimethyl diallyl ammonium chloride, 15-18 parts of 2-hydroxypropyltrimethyl ammonium chloride chitosan, 25-34 parts of water, 20-25 parts of ethanol and 5-10 parts of fatty alcohol polyoxyethylene ether. The fixing agent disclosed by the invention has an excellent fixation effect, and can effectively improve colour fastness of fabric dyes and wet rubbing fastness in the processes of dyeing and printing. The fabric treated by the fabric formaldehyde-free fixing agent does not discolor.

Description

technical field [0001] The invention belongs to printing and dyeing auxiliaries, in particular to an formaldehyde-free color-fixing agent for fabrics. Background technique [0002] Although the fibers and fabrics have relatively bright colors after dyeing, they are prone to fading and staining when washing. This is because some dyes have soluble groups on them, which make their fastness poor. It makes itself look old, and the faded color will stain other fabrics, which is very inconvenient. Therefore, color fixing agents are generally used to improve the color fastness of fabric dyes so that they will not fade. The existing color-fixing agents have been developed toward the direction of formaldehyde-free color-fixing agents, but there are still deficiencies in color fastness. Therefore, developing a composite formaldehyde-free color-fixing agent is a technical problem to be solved urgently in the existing field. Contents of the invention [0003] The object of the presen...
