AI Technical Summary

Problems solved by technology

But the operation is complex and costly
The main disadvantage of the dipping method is that it cannot solve the problem of air permeability
The scraping method is also mainly because the air permeability is not easy to solve
The method of transfer coating is also not a good solution to the problems of air permeability and uniformity
Therefore, the self-adhesive elastic bandage products currently on the market cannot completely solve the problems of gluing uniformity and air permeability.
Simultaneously, the rolling state of the product is not good (often delaminated), and the viscosity is not easy to control, etc., which also affects the production and use of the product. Risk of sensitization, serious life risk

Abstract

The invention relates to a self-adhesive elastic bandage and a manufacturing method thereof. The self-adhesive elastic bandage is composed of synthetic glue and elastic fabrics. The manufacturing method of the self-adhesive elastic bandage includes fabric preparation, glue preparation, fabric loading glue, drying, making Finished products and other process steps. The self-adhesive elastic bandage of the present invention is used for medical care, sports protection and positions where the bandage can be used for fixing, supporting, bandaging and other functions. Due to the hypoallergenicity of the bandage, good air permeability, good hand feeling, uniform viscosity, easy opening, and excellent anti-aging performance, it is an ideal product to replace traditional self-adhesive bandages.

Description

technical field [0001] The invention relates to medical and sporting goods and a manufacturing method thereof, in particular to a self-adhesive elastic bandage and a manufacturing method thereof. Background technique [0002] Self-adhesive elastic bandage is a product with a wide range of applications. It is characterized in that both sides of the elastic bandage are loaded with self-adhesive glue. and other properties. This type of product first appeared in the introduction of patents in European and American countries in the 1970s and 1980s. It is mainly used in medical, sports, labor insurance, animals, pets and other fields, and has the functions of nursing, protection and support. The conventional production method is the way of spraying glue. According to the relevant patent description, the way of spraying glue is used from ordinary air spray guns to electrostatic spray guns, which solves the problem of air permeability but the uniformity is not easy to solve. The...
