Method for fireproofing textiles

摘要

This invention relates to a method for fireproofing textiles based on a composition having two components comprising:
a component A comprising at least one phosphorous compound; anda component B comprising urea and at least one pH buffer, optionally with an oxidizing agent.;Said method for fireproofing textiles includes the steps of immersing said textiles in said composition, and of heating, oxidizing and then washing said textiles, which then have excellent human-ecological, comfort, and durable fireproofing properties.

主权项

1. A fireproofing treatment method for textiles, the method comprising:
a) preparing a first bath comprising a composition having two components A and B, with component A comprising at least one phosphorous compound and component B comprising urea and at least one pH buffer, the first bath having a pH of between 3.5 and 6; b) impregnating a textile to be treated in the first bath; c) heat-drying of the impregnated textile at a temperature between 130° C. and 165° C., during which drying a polymerisation reaction of the urea of component B and the phosphorous compound of component A occurs to produce a polymer; d) oxidizing the polymer in a second bath, wherein the second bath includes at least one oxidising compound, and a mixture of diacetone acrylamide and at least one organic acid dihydrazide; and e) washing in water and drying of the treated textile.
