芦荟多糖的提取及在棉织物上的应用

Extraction of aloe polysaccharide and application in cotton fabric

将芦荟多糖微胶囊化,提高芦荟多糖在外部条件下的稳定性,以拓宽其适用范围。采用水作为浸提液,用乙醇沉淀多糖以提取芦荟多糖;采用界面聚合法,以聚对苯二甲酰乙二醇为壳材,水作为非有机相乙二醇的溶剂,二甲苯作为有机相邻苯二甲酰氯的溶剂,以芦荟多糖提取浓缩液为芯材,制备芦荟多糖微胶囊。研究了浸提料液比、温度、时间、pH值对浸提效果的影响,确定其最佳提取工艺,并将微胶囊涂层到织物上。结果表明,整理后织物具有抗紫外线、抗菌和透湿等功能。

In order to enhance the stability of aloe polysaccharide, it is prepared into microencapsulation to broaden its application scope. Water is used as extract liquid, and ethanol is used to precipitate polysaccharides, to extract aloe polysaccharides. With the method of interfacial polymerization, using polyterephthaloyi ethylene glycol as shell material, water as a non-organic ethylene glycol solvents, and dimethylbenzene as an organic terephthaloyl chloride solvents, the extraction and concentration liquid of aloe polysaccharide as core material, the microcapsule of aloe polysaccharide was prepared and coated to fabric. The influence of the ratio of material to liquid, temperature, time, pH value on extraction effect is studied. The optimum extraction process is settled. The result shows that the finished fabric has a certain anti-UV, anti-bacterial and permeability properties.
