[0022] The preparation method of the modified fiber is to mix dimethylformamide, water and spandex at a mass ratio of 9:3:1-3, put in a mixture of 35-40% spandex mass, heat up to 130-135°C, and Press at 0.4 MPa, stir for 5 hours, cool to room temperature, discharge, rotary evaporate, heat-melt, and form filaments to obtain modified fibers.
[0023] The mixture is formed by mixing chlorodimethylsilane and dimethylsilanediol in an equal mass ratio.
[0024] The soaking solution is to mix the ammonium polyphosphate, water and modifying agent uniformly in a mass ratio of 9:16:1-3, under nitrogen protection, stir and react at 130-150°C, and cool to obtain the soaking solution.
[0025] The modifying agent is any one of vinyltriethoxysilane and vinyltris(β-methoxyethoxy)silane. The penetrating agent is any one of fatty alcohol polyoxyethylene ether and fast penetrating agent T.
[0026] The conditioning agent is chitosan.
[0027] The additive is any one of ethyl tetrasilicate an...
