以自制Ag/MWNTs抗菌剂为功能材料,采用紫外光辐照的方法制备了抗菌Ag/MWNTs-羊毛纤维。运用场发射扫描电镜、傅里叶红外光谱仪等对样品的形貌和结构进行了表征,同时表征了抗菌处理前后羊毛纤维的品质特征。研究结果表明羊毛纤维与具有良好抗菌功能的Ag/MWNTs抗菌剂紧密复合并通过偶联剂的架桥作用,在羊毛纤维表面形成以价键形式结合的抗菌层。与原羊毛相比,抗菌Ag/MWNTs-羊毛纤维长度较长,细度变细,卷曲回复率较高。
With Ag/MWNTs antibacterial agent as functional material,antibacterial wool fiber was prepared by the method of ultraviolet irradiation.The morphologies of samples were observed by scanning electron microscopy.The structures of specimens were characterized by Fourier transformation infrared spectrum.Moreover,the characteristics of wool fiber were measured before and after antibacterial treatments.The results show that wool fiber could firmly combine with the Ag/MWNTs composite which had excellent antibacterial effect.Furthermore,an antibacterial layer was formed on the surface of wool fiber by covalent bonding through the bridge action of coupling agent.Compared with original wool fiber,the Ag/MWNTs-wool fiber was longer and thinner with higher crimp recovery and crimp elasticity.
