Problems solved by technology

[0014] 1. The antibacterial effect is poor, and the extensive use of antibacterial fillers leads to poor mechanical properties such as the breaking strength of the prepared antibacterial non-woven fabric, and the scope of application is limited;
[0015] 2. The surface is impregnated with antibacterial agent, or the added small molecule antibacterial agent is easy to seep out and dissolve in solvent or water, which will easily weaken the antibacterial effect or even lose the antibacterial effect

Abstract

The invention discloses an antibacterial non-woven fabric and a manufacturing process thereof. The antibacterial non-woven fabric is prepared from composite fibers through a spunlace non-woven fabricproduction process; the composite fibers have a skin-core structure and comprises a core layer and a skin layer; the cross section outline of the core layer is regular pentagon, the skin layer wraps the outer surface of the core layer, and the cross section outline of the skin layer is circular; the cross section area ratio of the core layer to the skin layer is 1: (0.28-0.35); and the core layeris prepared from the following raw materials in parts by weight: 95-100 parts of polyethylene terephthalate, 2-5 parts of hydroxyl-terminated polysiloxane emulsion, 2-3.5 parts of pentaerythritol adipate and 10-15 parts of filler. The antibacterial non-woven fabric is excellent in antibacterial performance and good in antibacterial effect; the fracture strength is high, and the mechanical propertyis good; and furthermore, the antibacterial non-woven fabric has good elasticity and softness.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to an antibacterial non-woven fabric and a manufacturing process thereof. Background technique [0002] The fibers used in the production of non-woven fabrics are mainly polypropylene (PP) and polyester (PET). In addition, there are nylon (PA), viscose fiber, acrylic fiber, polyethylene fiber (HDPE), and chlorine fiber (PVC). According to application requirements, non-woven fabrics are divided into two categories: disposable application type and durable type. [0003] According to the production process, it is divided into: [0004] 1. Spunlace non-woven fabric: The spunlace process is to spray high-pressure fine water flow onto one or more layers of fiber nets, so that the fibers are entangled with each other, so that the fiber nets can be reinforced and have a certain strength. [0005] 2. Heat-bonded non-woven fabric: heat-bonded non-woven fabric refers to adding fib...
