Problems solved by technology

In addition, in the existing flame-retardant treatment of cotton fabrics, it usually needs to be processed by layer-by-layer self-assembly method. The disadvantage of this method is that the preparation process is relatively cumbersome, and multiple soaking and washing are required to obtain a better weight gain. Improve flame retardant effect

Abstract

The invention discloses a polyelectrolyte composite solution for flame-retardant treatment of cotton fabrics. The composite solution is a solution obtained by dissolving a mixture of chitosan and sodium polyborate in a solvent, the composite solution comprises the following components in percentage by mass in total: 0.5-4 wt% of chitosan and 4-30 wt% of sodium polyborate. The polyelectrolyte composite solution has a very good flame-retardant effect on the flame retardance of the cotton fabric, and compared with a layer-by-layer self-assembly method carried out through the interaction of positive and negative charges, a large amount of time is saved, the flame-retardant effect can be achieved only through a padding mode, and industrialization is easy to achieve. The finally prepared flame-retardant cotton fabric has the characteristics of simplicity in preparation, easiness in operation, high flame retardance and environment friendliness. The invention also discloses a preparation method and application of the polyelectrolyte composite solution.

Description

technical field [0001] The invention relates to the technical field of cotton fabric treatment. More specifically, it relates to a polyelectrolyte composite solution for flame-retardant treatment of cotton fabrics and its preparation method and application. Background technique [0002] Cotton fabric has many excellent properties, such as breathable and comfortable, stable size, smooth and wide, easy to wash and quick dry, etc., and has a very wide range of applications in clothing and furniture decoration. However, cotton fabric is very sensitive to flame, which will limit the further application of cotton fabric to a certain extent. And with the continuous increase of market demand for cotton fabrics, it is also necessary to carry out flame-retardant modification of cotton fabrics. Therefore, flame retardant treatment of textiles, reducing their combustion characteristics and reducing potential fire hazards is of great significance for protecting people's lives and reduc...
