Abstract

A method for preparing antibacterial nano-silver fiber with an electrostatic spinning method comprises steps as follows: 1), preparation of a spinning solution : a cotton fiber raw material and N-methylmorpholine oxide are mixed and dissolved at the temperature of 90-110 DEG C and stirred for 10-30 min, the cotton spinning solution is obtained, then, silver phosphate is added, and the mixture is stirred, so that silver phosphate is uniformly dispersed in the cotton spinning solution ; and 2), electrostatic spinning : the spinning solution prepared from the step 1 is added into a syringe with a needle, the needle is connected with a positive electrode of a high-voltage power supply, a grounded aluminum foil is paved under the syringe, the distance between the aluminum foil and the needle is 5-15 cm, the spinning solution is pulled into nanoscale fiber under the action of electric field force, and the nano-silver antibacterial fiber is obtained. According to the method, nano-silver and cotton fiber are blended and spun to obtain the fiber with an antibacterial function, the preparation method is simple, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for preparing nano-silver antibacterial fibers by electrostatic spinning. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to the safety of food, clothing, housing and transportation. Clothes are not only required to be comfortable, warm or cool, but also to have various other functions, such as antibacterial properties. The antibacterial property of clothing is generally realized by the finishing method. The antibacterial performance obtained by this method is not durable, and in the finishing process, it is inevitable to use various chemical finishing agents, and the chemical components will remain, which will affect people. health. The emerging functional fiber method blends antibacterial components with fibers. The clothing obtained by this method has a long-lasting antibacterial effect,...
