[0053] To use non-woven fabrics to make elastomeric substrates, first of all, choose raw materials that can meet the requirements of medical device dressings. Generally, non-woven fabrics mixed with polypropylene filaments or nylon filaments and polyester filaments are used. These materials have good properties such as softness, breathability, and comfort. Excellent performance, no irritation or allergy to human skin. The non-woven fabric manufacturing process should be hot-rolled or spunlace. These two manufacturing processes can meet the basic requirements of elastic bandages; the thickness of non-woven fabrics can be selected from 10 grams per square meter to 40 grams per square meter; the elasticity of spandex filaments can be 70D or 120D, and the larger t...

Abstract

The non-woven fabric medical self-viscolelasticity bandage is formed from non-woven fabric, polyurethane fibre and adhesive, and its production method includes the following steps: (1) selecting hot-rolled or hydro-entangled non-woven fabric, its thickness is 10g / sq.m-40g / sq.m; (2) elasticity range of polyurethane fibre is 70D-120D; (3) placting the non-woven fabric on the wide-width warp knitting machine, using polyurethane fibre as warp yarn, and making them into elastic non-woven fabric; (4) spraying adhesive onto both faces of elastic non-woven fabric; and (5) drying at 80-100 deg.c in oven so as to obtain the invented product.

Description

Technical field: [0001] The invention relates to a medical elastic bandage, in particular to a non-woven medical self-adhesive elastic bandage and a manufacturing method thereof. Background technique: [0002] Traditional gauze bandages do not fit well, are easy to slip, and have poor fixation. Traditional elastic bandages need to be fixed with special buttons, which is inconvenient to use. There are two main series of viscoelastic bandages at home and abroad, one is single-sided adhesive bandages, and the other is double-sided adhesive bandages. The common ones are adhesive plaster bandages, polymer bandages, polyurethane bandages, and resin bandages. Common features of these bandages are: [0003] 1. The adhesives used for viscous action are all synthetic high molecular polymers, most of which are non-water soluble; [0004] 2. Using smearing or spraying technology in the production process, a layer of viscous polymer material with a thickness of about 0.2-0.5mm is glue...
