Polyacrylonitrile Fiber Modified By Collagen Protein And Research In Its Dyeing Property

Polyacrylonitrile fiber is a kind of synthetic fiber,Looks fleeciness, soft,Have good flexibility and warmth retention property,But because it is hydrophobic fiber,its hygroscopic property is weak and it Produce electrostatic easily, its wearing comfort is much worse then wool,These shortcomings Limite its further development. So we Traditional polyacrylonitrile fibers needed to be modified,There are many different modified polyacrylonitrile fibers appears these years.This paper put forward polyacrylonitrile fiber modified by Collagen protein, Firstly we studied acid method and alkalinity method through the experiments respectively, we get the best hydrolysis polyacrylonitrile fiber process conditions is this:The Hydrolysis temperature is 80℃,Hydrolysis reaction time is 15 min,Sodium hydroxide concentration is 12％.We modified polyacrylonitrile fibre with Collagen protein solution in ihs surface,this paper explore baking method and steaming method,finally we Have the best technology polyacrylonitrile fiber modified by collagen protein as follow:Collagen protein concentration is 5%,baking temperature is 110℃,baking time is 15 min.In this paper we dye modified polyacrylonitrile fiber with Cationic dye, acid dyes,and direct dyes and studied its dyeability, we studied its Dyeing dynamics and thermodynamics,then we Calculates correlative parameters,we laid a theoretical foundation.for this kind of new fiber dyeing process...
