Preparation method of reactive flame retardant, product of reactive flame retardant and application of reactive flame retardant in cotton fibers

The invention discloses a preparation method of a reactive flame retardant, a product of the reactive flame retardant and application of the reactive flame retardant in cotton fibers, and when AMPA is successfully loaded to cotton fabrics, the flame retardant effect and thermal stability of the cotton fabrics are greatly improved. The cotton fiber finished by the 60g/L flame retardant can pass a UL-94 vertical combustion test, and the afterflame time and the smoldering time are both 0. The finished cotton fiber keeps the mechanical property of the cotton fabric, and the prepared modified cotton fabric also has excellent anti-wrinkle and antibacterial properties. 本发明公开了一种反应型阻燃剂的制备方法及其产品和在棉纤维中的应用，当AMPA成功负载到棉织物时，其阻燃效果和热稳定性能均有极大的提升。用60g/L阻燃剂整理的棉纤维可以通过UL-94垂直燃烧测试，续燃时间和阴燃时间均为0。整理后的棉纤维保持棉织物的力学性能，制备的改性棉织物还具有优异的抗皱和抗菌性能。
