Study on peparation of phosphate ester fiber by half-dry synthesis pocess
摘要
Abstract
In this study,the high degree of substitution of phosphate ester fiber was prepared by using cotton phosphate as raw material,mixed phosphate NaH2 PO4/Na2 HPO4 as esterif-ying agent and urea as catalyst with half-dry synthesis process.The effects of the dosage of phosphate,reaction temperature,time and pH on the degree of substitution and reaction effi-ciency of phosphate ester fiber were investigated.The results showed that the degree of sub-stitution of phosphate ester fiber was 0.066 when the amount of phosphate was 20%,the re-action temperature was 120 ℃,the reaction time was 2 h,pH 6.0 and the amount of urea was 4%,the reaction efficiency of the fiber was 42.7%,and the fiber was most damaged.关键词
