[0056] To use non-woven fabrics to make elastomer substrates, you must first select raw materials that can meet the requirements of medical device dressings. Generally, non-woven fabrics of polypropylene yarn or nylon yarn and polyester yarn are used. These materials are soft, breathable, comfortable, etc. The performance, no irritation or allergy to human skin. The non-woven fabric manufacturing process should be hot-rolled or spunlaced. These two manufacturing processes can meet the basic requirements of elastic bandages; the weight per unit area of ​​non-woven fabrics can range from 10 grams per square meter to 40 grams per square meter; the size of spandex filaments can be 70D or 120D, the larger the number of spandex filaments It means that the thicker the spandex yarn, the stronger the elasticity. Place the non-woven fabric on a wide warp knitting machine and use spandex yarns to sew into rows of fabrics at equal intervals o...

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 are unacceptable, easy to slip off, and have poor fixation. Traditional elastic bandages need to be fixed with special buttons, which is inconvenient to use. Existing domestic and foreign viscous elastic bandages mainly have two series of products, one is single-sided adhesive bandages, and the other is double-sided adhesive bandages. The common ones are viscous plaster bandages, polymer bandages, polyurethane bandages, and resin bandages. The common features of these bandages are: [0003] 1. The adhesives used are all synthetic high molecular polymers, and most of them are non-water-soluble; [0004] 2. Applying painting or spraying technology in the production process, glue a layer of viscous liquid polymer material with a thickness of about 0....
