Abstract

The invention relates to stretch cotton self-adhesive elastic bandage and a preparation method thereof. Self-adhesive glue layers are coated to front and rear sides of a base material, and the base material comprises pure cotton gauze and spandex which is bonded on the pure cotton gauze. The preparation method comprises the following steps: selecting the pure cotton gauze which has the yarn countof 16-30S, warp density of 25-35 yarns / 2.54cm and weft density of 24-32 yarns / 2.54cm; selecting the spandex being 60-150D for stitch bonding; bonding the spandex on the pure cotton gauze at an interval of 6-12 yarns / 2.54cm; and coating self-adhesive glue to front and rear sides of the spandex-bonded pure cotton gauze, and performing drying and curing through an oven. Elasticity is provided to thepure cotton gauze by adopting a spandex stitch-bonding mode, and the product has excellent easy-to-tear performance, can be torn in horizontal and vertical directions and has an excellent air-permeable effect.

Description

technical field [0001] The invention relates to a novel elastic cotton self-adhesive elastic bandage and a preparation method thereof, belonging to the technical field of medical bandaging and sports protection products. Background technique [0002] Self-adhesive elastic bandage is a special elastic bandage, which has good elasticity and self-adhesiveness. Bandages can be bonded without sticking skin, hair and clothing. It is widely used in medical and sports fields, and is usually used for fixing wound dressings, post-operative pressure bandaging, auxiliary treatment of varicose veins, protection during sports, and bandaging and fixing of injured parts. [0003] The base material of the self-adhesive elastic bandage is generally elastic non-woven fabric, cotton cloth or composite fabric, and then a self-adhesive adhesive is coated on the surface of the base material. Tear resistance, but the way of providing elasticity - the manufacturing process of spandex core-spun yarn...
