1. cashmere is carried out to a method for graft modification, it is characterized in that, described method comprises:

  • Step 1, pending cashmere is added in reaction medium, preheating 15 ~ 20 minutes at temperature is 30 ~ 80 DEG C, and holding temperature 30 ~ 80 DEG C, to add after initator reaction 10 ~ 15 minutes;

    Step 2, by the preheating 15 ~ 20 minutes at temperature 30 ~ 80 DEG C of grafted monomers and emulsifying agent, and holding temperature 30 ~ 80 DEG C reaction 10 ~ 15 minutes;

    Step 3, the obtained emulsified monomer of step 2 will be added in reactant obtained for step 1, and regulate the pH value of reaction system 3 ~ 7, holding temperature 30 ~ 80 DEG C, carry out graft reaction cessation reaction after 30 ~ 180 minutes, obtain the cashmere after graft modification;

    Step 4, the cashmere after described graft modification carried out drying process.
