Abstract

The invention discloses a method for preparing a flame-retardant cotton fabric. Natural phytic acid compounds and γ-glycidoxytrimethoxysilane are added to an organic solvent, and stirred and reacted at 50-80°C for 0.5-2 hours to obtain Flame retardant finishing solution, soak the cotton fabric in the above flame retardant finishing solution for 8-15 minutes, then dip and roll twice, then dry the cotton fabric at 60-90°C, and then bake it at 150-180°C for 2 ~8 min, finally wash with water, soap and dry. Using natural phytic acid as the reaction raw material, there is no release of free formaldehyde on the prepared flame retardant textiles, which solves the problem of formaldehyde release from most current flame retardants, and introduces γ‑glycidoxytrimethoxysilane into the flame retardant In the molecule, the prepared flame retardant contains multiple reactive groups, which solves the durability problem of flame-retardant finishing of cotton fabrics. The technical solution of the invention is simple in process, easy to operate, and has broad application prospects.

Description

technical field

[0001] The invention belongs to the technical field of dyeing and finishing, and relates to a flame retardant finishing method using natural phytic acid derivatives as raw materials as flame retardants for cotton fabrics. The phytic acid used in the method is a natural phytic acid extracted from plant seeds. Phosphorus compounds, in particular, can realize the safety and environmental protection of flame-retardant finished fabrics. The prepared flame retardant has multiple reactive groups, which can endow the fabric with better flame-retardant durability. Background technique

[0002] With the advancement of science and technology and the improvement of people's living standards, the demand for flame-retardant textile fabrics is increasing. Among the flame-retardant finishing agents for cotton fabrics, tetramethylol-based flame retardants (THPC or THPOH) and N-methylol- 3-Dimethoxyphosphorylpropionamide flame retardants (trade name Pyrovatex CP) are currently...
