海藻酸纤维化学稳定性研究

ccording to peculiarities of dyeing and finishing processing, the stabilities of alginate fibers were primary studied and discussed such as resistance to acid and alkali, salt endurance and oxidation resistance which provide alginate fiber a theoretic basis for the development and application of textile industry. Results of this study indicate that alginate fiber can not resist acid and alkali, both salt endurance and oxidation resistance of alginate fiber are worse; various factors were applied to research the weight-lost of the fiber, such as concentration，temperature and time. Results of these still indicate that the temperature is the primary reason and the next is concentration and treatment time. The influence of temperature to the acid resistance and oxidation resistance of alginate fiber is extremely obvious. Almost all of the alginate fiber was degraded into small molecules and then dissolved at 80℃.
