Abstract

The invention discloses a complex self-adhesive elastic bandage and a manufacturing method thereof. The complex self-adhesive elastic bandage comprises an upper non-woven fabric layer and a lower non-woven fabric layer, wherein a polyurethane filament layer is sandwiched between the upper non-woven fabric layer and the lower non-woven fabric layer, and a bandage substrate is formed by combining the upper non-woven fabric layer, the polyurethane filament layer and the lower non-woven fabric layer; complex adhesive layers are coated on the front side of the upper non-woven fabric layer and on the back side of the lower non-woven fabric layer; the complex adhesive layers include polyisoprene and polyacrylate; the non-woven fabric layers make use of a polypropylene non-woven fabric; fibers of the polypropylene non-woven fabric are in directional alignment in a longitudinal direction, and a longitudinal arrangement proportion of the fibers of the polypropylene non-woven fabric is 70-90%; polyurethane filaments of the polyurethane filament layer are subjected to 60-120D specification; and warp-wise density of the polyurethane filaments is 7-11 polyurethane filaments / inch. The bandage, which is telescopic in a transverse direction, can be stretched by 20-40%, so that binding and fixing on special parts are facilitated; and the bandage has an easy-to-tear property in both transverse and longitudinal direction, with clear and tidy torn surfaces.

Description

technical field [0001] The invention relates to a composite self-adhesive elastic bandage and a manufacturing 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, usually used for fixing wound dressings and indwelling needles, postoperative 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. Then apply a self-adhesive adhesive on the surface of the substrate. Products currently on the market are not stretchable in the horizontal direction. Contents of the invention ...
