Abstract

The invention provides a preparation method of a flame-retardant modified polyester fabric. The preparation method comprises the following steps of S1, modifying a polyester fabric; S2, preparing low-molecular-weight open-loop sodium hyaluronate; S3, preparing a modification solution: preparing a silk peptide solution and a sodium hyaluronate mixed solution, then adding citric acid and sodium hypophosphite, and performing uniform mixing; S4, padding and finishing the fabric: adding the modified polyester fabric prepared in the step S1 into the modification solution, and carrying out padding and baking treatment; and S5, performing flame-retardant modification of the fabric: dipping the fabric treated in the step S4 in a CaCl2 solution for constant-temperature water bath treatment, performing baking, putting the treated fabric in a SbCl3 solution for constant-temperature water bath treatment, taking out the fabric from the solution, and performing baking to obtain the flame-retardant modified polyester fabric. A preparation method of a phosphorus-containing flame-retardant fabric in the prior art is improved, and the flame-retardant modified polyester fabric is obtained through a composite modification method.

Description

technical field [0001] The invention relates to the field of functional fabrics, in particular to a method for preparing flame-retardant modified polyester fabrics. Background technique [0002] Polyester fabrics can form molten drips when burned, causing flame spread and secondary injury. Anti-melt drop is one of the difficulties in flame retardancy of polyester fabrics. The flame retardant modification methods of polyester fabric mainly include the flame retardant modification of polyester raw silk or the surface treatment modification of polyester fabric. Fabric flame retardant finishing has the advantages of simple process and low cost, and is one of the surface treatment modification methods. Among them, phosphorus-containing flame retardants have the advantages of low toxicity and high efficiency, and are more and more used in the flame-retardant finishing of fabrics, and have broad development prospects in the field of textile flame-retardant. Studies have shown th...
