Embodiment 1
[0036] In this embodiment, a sericin modified polyester raschel blanket is an antistatic and antibacterial polyester raschel blanket grafted with sericin protein on the fiber surface, and its preparation steps are as follows:
[0037] 1) Alkali reduction: take the pretreated and air plasma treated polyester raschel blanket and paddle it with lye, steam at 110°C for 10 minutes, fully wash, neutralize, and dry to obtain the polyester raschel to be modified Blanket; among them, the pretreatment is to immerse the polyester raschel blanket in 1g / L sodium hydroxide aqueous solution at 40°C for 45min at a bath ratio of 1:20, take it out, wash with water, neutralize, and dry; the power of air plasma treatment is 1000W , the time is 20s; the excess rate of polyester raschel blanket padding lye is 10%; the lye contains the following components by weight: sodium hydroxide 50g, hydrolysis accelerator 5g, water 10000g; hydrolysis accelerator is Hexadecyltrimethylammonium bromide;
