银作为一种贵重金属，其优良的抗菌性能早已被人们所熟知并加以利用。纳米银结合了金属银的抗菌性和纳米材料独特的小尺寸效应、量子尺寸效应、表面效应和宏观量子隧道效应等特性，其抗菌性增大至上千倍，且纳米银的粒径较小，使纳米银能够穿透细菌与病毒的细胞壁与细胞用于呼吸的酶结合，使细胞窒息而死，并且不会改变细菌、病毒的基因，因而纳米银具备高效、广谱的抗菌性以及良好耐药性。As a precious metal, silver has long been known and utilized for its excellent antibacterial properties. Nano-silver combines the antibacterial properties of metallic silver with the unique small size effect, quantum size effect, surface effect and macroscopic quantum tunneling effect of nanomaterials. Nano-silver can penetrate the cell walls of bacteria and viruses and combine with the enzymes used by cells for respiration, suffocate the cells to death, and will not change the genes of bacteria and viruses, so nano-silver has high-efficiency, broad-spectrum antibacterial properties and good resistance Medicinal properties.
中国专利CN200410062799.3公开了一种抗菌粘胶纤维的制备方法，将纳米银胶体水溶液加入到纺丝原液中，然后按常规湿法纺丝喷丝工艺成型，得到抗菌粘胶纤维，该工艺制得载银抗菌粘胶纤维对载银量难以控制，且由于纳米银易团聚，易堵塞喷丝头，影响纺丝工艺生产效率；现有技术中也有对纤维加工后织物（面料等）在后处理过程中实现载银抗菌，该种工艺织物的手感较差，且耐洗性不好，抗菌效果差。Chinese patent CN200410062799.3 discloses a preparation method of antibacterial viscose fiber. The aqueous solution of nano-silver colloid is added to the spinning stock solution, and then shaped according to the conventional wet spinning and spinning process to obtain antibacterial viscose fiber. Silver-loaded antibacterial viscose fiber is difficult to control the silver-loaded amount, and because nano-silver is easy to agglomerate, it is easy to block the spinneret, which affects the production efficiency of the spinning process; Silver-loaded antibacterial is realized in the process of treatment, but the hand feeling of this kind of craft fabric is poor, and the washability is not good, and the antibacterial effect is poor.

为实现上述目的，本发明提供如下技术方案：To achieve the above object, the present invention provides the following technical solutions:
一种载银抗菌粘胶纤维的制备方法，包括以下步骤：A preparation method of silver-loaded antibacterial viscose fiber, comprising the following steps:

1、当吸湿溶胀纤维放入硝酸银溶液中，在粘胶纤维纳米孔道的芯吸作用下，硝酸银溶液慢慢进入粘胶纤维的空隙内，在纤维大分子末端暴露的醛基的还原作用下，银离子慢慢原位还原成单质银粒子，由于纤维孔道的限域作用，银粒子均匀分布在纤维的内外表面，有效防止了纳米银的团聚。1. When the hygroscopic swelling fiber is put into the silver nitrate solution, under the wicking effect of the viscose fiber nanopore, the silver nitrate solution slowly enters the gap of the viscose fiber, and the reduction of the aldehyde group exposed at the end of the fiber macromolecule Under this condition, the silver ions are slowly reduced into simple silver particles in situ. Due to the confinement effect of the fiber pores, the silver particles are evenly distributed on the inner and outer surfaces of the fibers, which effectively prevents the agglomeration of nano-silver.
2、当载银粘胶纤维放入硅烷偶联剂中，由于硅烷偶联剂水解生成硅醇，分别与纳米银表面的羟基和粘胶纤维上的羟基发生反应，同时，硅烷偶联剂分子的硅醇又相互缔合并聚合形成网状结构的膜，覆盖在纤维表面，使银粒子与纤维牢固结合的同时，使纤维更加柔软顺滑。2. When the silver-loaded viscose fiber is put into the silane coupling agent, the silane coupling agent is hydrolyzed to generate silanol, which reacts with the hydroxyl groups on the surface of the nano-silver and the hydroxyl groups on the viscose fiber respectively. At the same time, the silane coupling agent molecules The silanols are associated with each other and polymerized to form a film of network structure, covering the surface of the fiber, so that the silver particles and the fiber are firmly combined, and the fiber is softer and smoother.
3、本发明的制备方法操作简单，成本低，制得的抗菌粘胶纤维，手感柔软，抗菌效果好，耐50次以上水洗，不易断裂，使用寿命长。3. The preparation method of the present invention is simple in operation and low in cost. The antibacterial viscose fiber produced has soft hand feeling, good antibacterial effect, wash resistance of more than 50 times, is not easy to break, and has a long service life.
