Manufacturing method of composite medical non-woven fabric absorbent pads

Abstract

The invention relates to a manufacturing method of composite medical non-woven fabric absorbent pads and belongs to the field of preparation of medical dressing. The manufacturing method includes steps of feeding medical non-toxic polyethylene particles into a screw extruder to fuse and extrude, forming a film through curtain coating, rolling to form anti-adhesive holes, cooling and winding to obtain a medical non-toxic polyethylene film used as an anti-adhesive layer; subjecting blended fibers blended by viscose fibers and high-absorbent fibers to opening by an opener, carding by a carding machine, lapping by a lapping machine and needling by a needle machine, and obtaining non-woven fabric used as a liquid absorbent layer; feeding polyurethane particles into the screw extruder to fuse and extrude, and forming a film by curtain coating, cooling and winding to obtain a polyurethane film used as a waterproof breathable layer; subjecting the anti-adhesive layer and one surface of the liquid absorbent layer to thermal compositing, and subjecting the waterproof breathable layer and the other surface of the liquid absorbent layer to thermal compositing to obtain a composite medical non-woven fabric absorbent pad. The manufacturing method of the composite medical non-woven fabric absorbent pads has the advantages that liquid absorbent quantity is high, leakage to the outside is prevented, contact area of the skin can be remarkably decreased, handling time of medical staff can be shortened, and technical steps are few.

Description

technical field

[0001] The invention belongs to the technical field of preparation of medical dressings, and in particular relates to a preparation method of a composite medical non-woven absorbent pad. Background technique

[0002] In people's daily life, they often encounter various types of bleeding trauma. For small wounds, band-aids are directly applied to the wounds. For large wounds, the wounds need to be cleaned and disinfected by the medical staff of the hospital, and then wrapped with gauze, or pasted with various class applicator. But the dressings in the prior art such as Band-Aid, gauze or application tend to leak through the gauze or application when the wound bleeding is large, especially, when the wound heals, it is easy to adhere to the dressings such as gauze. Then, when the wound is healed and the gauze is removed, it will cause pain to the patient and even lead to secondary bleeding.

[0003] There is no lack of technical information on medical dressin...
