摘要: 为了改善纤维的吸湿性能,采用氯乙酸处理纤维素纤维来制备羧甲基纤维素纤维。通过控制氯乙酸和纤维的质量比得到不同反应程度的羧甲基纤维素纤维。实验结果显示,由于处理后纤维的结构中含有高吸水性的羧甲基基团,处理后的纤维比初始纤维有更高的吸湿性。当被加工成医用敷料后,这种具有高吸湿性的羧甲基纤维素纤维可以吸收大量的伤口渗出液。羧甲基纤维素纤维可以把液体吸收进纤维内部,使纤维在吸湿后转化成一种水凝胶体,在伤口上可以形成一个适合创面愈合的潮湿环境,在伤口护理中有很高的应用价值。

Abstract: In order to improve the hydroscopic property of fibers,cellulose fibers were treated with chloroacetic acid to prepare carboxymethyl cellulose fibers.Fibers with different degrees of carboxymethylation were prepared by controlling the ratio of the weight of fiber to chloroacetic acid.Experimental results showed that the treated fibers had much higher hydroscopicity than the untreated ones,due to the highly absorbent carboxymethyl groups in the fiber structure.When made into wound dressings,these highly absorbent carboxymethyl fibers can absorb a large amount of wound fluid.The results of this study confirmed that carboxymethylated cellulose fibers absorb liquid into the inside of fiber,and become a hydrogel when being wet.Because they can create a moist environment suitable for wound healing,this type of product is highly valuable in wound care.
