Problems solved by technology

In the traditional antibacterial drug fiber, the antibacterial component adheres to the surface of the fiber, the adhesion is limited, and the impregnation amount is difficult to keep constant, so the antibacterial stability, durability, and washability are poor
[0010] 2. The texture is poor and the comfort is not enough. The antibacterial non-woven fabric processed by hot rolling or gluing or thermal bonding process has a stiff surface. After the spunlace process, the bulkiness of the product has improved, but the product contains a certain amount of The surface of the drug fiber, its feel is still not comparable to the original fiber spunlace nonwovens
[0011] 3. There are no large-scale production conditions, and the cost is high. The traditional antibacterial non-woven fabric has a long process route and poor stability. It cannot achieve large-scale production, so the cost is high, which limits its application range and market acceptance.

Embodiment 1

[0027] Embodiment 1: carry out according to the process flow diagram shown in Figure 1:

[0028] 1. Production of antibacterial masterbatch: Take 40kg of silicate silver-loaded antibacterial material with an average particle size of 1.5um, 50kg of fiber-grade polypropylene resin, and 10kg of dispersant polyethylene wax, stir and mix evenly, and then pass through a twin-screw extrusion granulator Melt and granulate at 140°C to make antibacterial masterbatch, the specification of antibacterial masterbatch is φ3mm×5mm, and the melt index is 110g / 10min;

[0029] 2. Production of antibacterial spunbond mesh: Mix 10kg of antibacterial masterbatch and 1000kg of fiber-grade polypropylene resin evenly, and use conventional spunbond equipment to spin and lay the mesh at a melting temperature of 285°C to make 50g / M 2 antibacterial spunbond mesh;

[0030] 3. Production of composite antibacterial non-woven fabric: combine antibacterial spunbond net with 25g / M 2 The cotton fiber web is su...

Embodiment 2

[0031] Embodiment 2: The process of this embodiment is basically the same as that of Embodiment 1, except that the cotton fiber web is replaced with 20g / M 2 The composite antibacterial non-woven fabric made of wood pulp fiber net has similar properties to the previous example.

Abstract

A process for preparing Ag-carried antibacterial composite non-woven fabric includes preparing antibacterial mother particles from Ag-carried antibacterial material, fibre resin and plastic assistant by screw extruding, preparing antibacterial spun-bonded mesh from said antibacterial mother particles and fibre resin, combining said antibacterial spun-bonded mesh with cotton fibre mesh or wood pulp fibre mesh, hydro-entangling, and drying. Its advantages are high antibacterial power and durability, and broad spectrum.

Description

technical field [0001] The invention relates to a method for manufacturing an antibacterial nonwoven fabric, in particular to a method for manufacturing a silver-loaded antibacterial composite nonwoven fabric. Background technique [0002] Non-woven fabric is a modern new material industry with high technical content, wide market demand, wide scope, beyond imagination and infinite development in the flexible material production system. uprising industry". Although non-woven fabrics produced by different processes have superior effects in improving the hygienic environment and facilitating use. However, human skin and clothes are places where bacteria breed. These bacteria use urea and other human excrement in sweat as a source of nutrition, continuously reproduce, and emit ammonia with a strong odor. Especially in hospitals, stations, shopping malls, cinemas, public transport vehicles and other places, as well as daily necessities that are prone to bacteria, such as: rags,...
