乙烯-乙烯醇共聚纤维的戊二醛交联改性

通过对戊二醛的用量、交联反应时间和交联温度对乙烯－乙烯醇共聚纤维的耐熨性和染色性的影响的研究，认为用戊二醛改性能有效地提高纤维的耐熨温度和降低染色温度，测定了交联改性纤维的力学性能，声速取向，溶胀度，热性能，证实耐熨烫性的提高是表层交联的结果，染色性的改进是内部结构的破坏所造成的。

Crosslinking Modification of Ethylene-vinyl Alcohol Copolymer Fiber by Glutaraldehyde

The effect of the concentration of glutaraldehyde, temperature and reaction time on the ironing resistance and dyeability of the modified EVOH fiber were studied. The result which ironing temperature raised and dyeability improved by glutaraldehyde was achieved. The structure of the modified fiber was characterized by differential scanning calorimetry, sonic velocity method, and swelling test. It was pointed out that the ironing resistance of the fiber was connected with crosslinking of surface of fiber directly. Due to the damage of internal structure of fiber ,The chromaticity of the modified fiber was improved.
