Experimental Design and Optimization of Polyaldehyde Sodium Alginate Casein Absorbable Fibers
In order to prepare a degradable absorbing fiber based on casein,the problems of low mechanical strength,easy swelling and fast degradation of the existing casein-based fiber are solved.Using polyaldehyde sodium alginate and polyethylene glycol diglycidyl ether as crosslinking agents,improvement of composite casein fibers,preparation of degradable bio fibers is based on casein as the main material through wet spinning process.The results indicate when the addition amount of sodium alginate aldehyde is 4 g,the addition amount of casein is 20 g,and the addition amount of sodium chloride is 2.0 g,the fiber has the maximum tensile strength of 1.68 cN/dtex,and degradation time is 7 d.The degradable absorption fiber has good biocompatibility and degradability,and has no cytotoxicity.It can meet the needs of practical applications of degradable fibers,broaden the practical application scenarios of casein,and provide new preparation ideas for the field of absorbable fibers.
