Embodiment 1

[0029] The invention discloses a production process of antibacterial nanofiber yarn, specifically comprising the following steps: sequentially performing cleaning, carding, combing, drawing, roving and spun antibacterial fiber, cotton fiber and nylon fiber to prepare antibacterial nanofiber yarn.

[0030] Antibacterial fiber is made by the following steps:

[0031] Step A1: Mix benzene and aluminum trichloride evenly, stir at a speed of 150r / min and a temperature of 18°C, add acetaldehyde, and react for 4 hours to obtain intermediate 1, and add intermediate 1 to In the reaction kettle, under the condition that the rotation speed is 200r / min and the temperature is 50°C, stir and add mixed acid dropwise, and react for 1h to obtain intermediate 2. Mix intermediate 2, tin and concentrated hydrochloric acid evenly, and Under the conditions of 150r / min and 100°C, the reaction was carried out for 30 minutes, and the pH value of the reaction solution was adjusted to be alkaline to obt...

Abstract

The invention discloses a production process of antibacterial nanofiber yarns. The production process comprises the following steps of sequentially scutching, carding, combing, drawing, roving and spinning antibacterial fibers, cotton fibers and polyamide fibers to obtain the antibacterial nanofiber yarns. Antibacterial graphene takes graphene as a base material, and the graphene has sharp edges due to a lamellar structure, so that bacteria can be physically cut, cell membranes of the bacteria are destroyed, membrane potential is reduced or electrolyte is leaked to inhibit growth of the bacteria; meanwhile, the surface contains a large amount of pyridine quaternary ammonium salt, and positive charge on the pyridine quaternary ammonium salt acts with head groups of acidic phospholipids in bacterial membranes, so that the permeability of the cell membranes is reduced, cell sap leaks, and cells die; and differing from traditional antibacterial fiber, antibacterial fiber has a more lasting antibacterial effect and can still keep a good antibacterial effect after being washed for multiple times; and compared with traditional silver-loaded fiber, the antibacterial fiber is low in preparation cost and good in effect.

Description

technical field [0001] The invention relates to the technical field of antibacterial material preparation, in particular to a production process of antibacterial nanofiber yarn. Background technique [0002] Fiber is the basic unit of textiles, which determines the functional properties of textiles. Fiber is a substance composed of continuous or discontinuous filaments, and is widely used in many fields such as textiles, military affairs, environmental protection, medicine, construction, and biology. There are two types of fibers: natural fibers and chemical fibers. Natural fibers exist naturally and are divided into plant fibers, animal fibers and mineral fibers; while chemical fibers are processed through chemical treatment and can be divided into man-made fibers, synthetic fibers and inorganic fibers. [0003] Polyester has a wide range of uses and is widely used in the manufacture of clothing fabrics and industrial products. Polyester has excellent set properties. Th...
