Embodiment 1

[0017] S1: The fine fiber polymer includes low-melting chemical fiber, carpenter fiber and wood pulp, low-melting chemical fiber: wood pulp fiber: carpenter = 5:3:1, the mixture of fine fiber polymer and binder fiber is made by a large screw High-temperature melt extrusion, the heating temperature is 260 ° C, to obtain polymer A in a molten state;

[0018] S2: Spinning polymer A through an extruder at a pressure of 4.8 MPa, stretching the filaments through a stretcher to form a fiber drawing B, and guiding it into the soaking liquid for 4 hours, and then guiding it to air-laid On the machine, the components of the soaking solution are as follows: 30 parts of astragalus extract, 20 parts of acrylate, 0.01 part of triclosan, and 30 parts of ethylene glycol;

[0019] S3: When the three-layer fiber drawing material B is stacked on the web forming machine, guide the laminate to the hot rolling mill for hot rolling. During hot rolling, the surface of the fiber drawing material is ev...

Abstract

The invention discloses a preparation method of an antibacterial medical non-woven fabric, comprising the following steps: S1, melt-extruding a mixture of a fine fiber polymer and binder fibers by a large screw at a high temperature of 260-280 DEG C to obtain a molten polymer A; S2, spinning the polymer A by an extruder under the pressure of 4.8-5.3 MPa, stretching the spun fibers by a stretcher to form a fiber stretching material B, guiding to a soaking solution for soaking for 4-8 h, and then guiding to a lapper; and S3, when three or four layers of fiber stretching material B are laminatedon the lapper, guiding a laminate to a hot rolling mill for hot rolling at 160-180 DEG C under 4 MPa, uniformly spraying resin powder to the surface of the fiber stretching material during hot rollingto obtain a non-woven fabric, and winding the non-woven fabric. On the basis of ensuring toughness, the non-woven fabric has excellent antibacterial ability and low cost, and is particularly suitablefor small hospitals.

Description

technical field [0001] The invention relates to the field of non-woven fabric preparation, in particular to a preparation method of antibacterial medical non-woven fabric. Background technique [0002] Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or machinery, and then undergoes hydroentanglement, needle punching, or hot rolling reinforcement, and finally finishes finishing Formed non-woven fabric. A new type of fiber product with soft, breathable and planar structure. The advantage is that it does not produce lint, is strong, durable, and silky soft. It is also a kind of reinforcing material, and it also has a cotton feel. Compared with cotton fabrics, non-woven fabrics Cloth bags are easy to form and inexpensive to make. [0003] The expansion of the application field of non-woven fabrics, non-woven fabrics are widely used in the medical field, but although the current non-wove...
