natural antibacterial agent



近年来,由于回归大自然和环保意识的增加,利用天然物质提供同样功能性的话题,引起了人们极大的兴趣。在纤维染整加工中很早就利用动物、植物、和矿物质用于染色。关于抗菌防臭功能的整理,近年也获得了相当大的进展。天然抗菌剂主要是来自天然物质的提取物,如壳聚糖来自于天然贝壳、蟹壳、虾壳、鱼骨及昆虫等动物壳体,经脱去N-乙酰基获得。由于天然抗菌剂不属于化学制品,是从天然动植物中提取或直接使用的,在生产和使用过程中,对环境一般不产生…

近年来,由于回归大自然和环保意识的增加,利用天然物质提供同样功能性的话题,引起了人们极大的兴趣。在纤维染整加工中很早就利用动物、植物、和矿物质用于染色。关于抗菌防臭功能的整理,近年也获得了相当大的进展。天然抗菌剂主要是来自天然物质的提取物,如壳聚糖来自于天然贝壳、蟹壳、虾壳、鱼骨及昆虫等动物壳体,经脱去N-乙酰基获得。由于天然抗菌剂不属于化学制品,是从天然动植物中提取或直接使用的,在生产和使用过程中,对环境一般不产生污染,生物相容性好,因而受到亲睐。但其缺点也很明显:160~180℃就开始碳化分解,使应用范围受到很大限制。

Currently, one of the only ways to use natural antibacterial agents to treat textiles is microencapsulation technology. This technology wraps the active ingredients of one or several natural antibacterial extracts in microcapsules and then fixes them in the fiber, making it a health care product. textile �一些纤维里的胶囊和皮肤接触摩擦时就爆裂开,散发出抗菌物质,发挥其卫生保健作用� �对于抗菌微胶囊,通常通过改变壁材的组成和厚度,来控制微胶囊抗菌剂的释放速度,延长使用时间� �应用时可以通过涂层加工或采用浸轧法与固着剂等一起应用,使微胶囊结合在纺织品上� �这类抗菌剂的主要产品主要如下表:</p
