Abstract

The invention relates to a durable flame-retardant protein fiber product and a preparation method thereof, and relates to the technical field of flame-retardant finishing of textiles. Phytic acid, p-hydroxybenzaldehyde and amino silane are used as raw materials to construct a flame-retardant coating on the surface of a protein fiber product, phytic acid enters protein fibers through adsorption to generate ionic bond combination with the fibers, p-hydroxybenzaldehyde and amino silane are subjected to a Schiff base reaction to generate an insoluble coating, and the surface of the protein fibers is coated with the insoluble coating. The phytic acid is fixed in the protein fiber, and the durable flame-retardant protein fiber product is prepared. The durable flame-retardant protein fiber product disclosed by the invention not only has an excellent flame-retardant effect, but also has good washing resistance. The preparation process is simple and convenient, conditions are mild, formaldehyde release does not exist, and the method has wide application prospects and important practical application value.

Description

technical field [0001] The invention relates to the technical field of flame retardant finishing of textiles, in particular to a durable flame retardant protein fiber product and a preparation method thereof. Background technique [0002] Wool fiber macromolecules are composed of keratin, the fibers are soft and elastic, and are often used in winter woolen clothing, blankets, curtains, high-end clothing and industrial textiles. Silk is composed of animal protein and contains a variety of amino acids. It has affinity for human skin and is praised as the "Queen of Fibers". Compared with other natural fibers, protein fibers such as wool and silk have certain flame retardant properties. However, with the improvement of the use of the textile industry, higher requirements have been placed on the flame retardant properties of protein fiber products. The use of biomass flame retardants to prepare environmentally friendly flame retardant textiles is the current development trend. ...
