Manufacturing method of self-adhesive elastic bandage and self-adhesive elastic bandage

Abstract

The invention discloses a manufacturing method of a self-adhesive elastic bandage and the self-adhesive elastic bandage. The method comprises the following steps of: sizing, i.e., sizing a non-woven fabric base material, wherein the pulp for the sizing treatment comprises an adhesive agent, a penetrating agent and a solvent; drying, i.e., drying the sized non-woven fabric base material; and coiling, i.e., coiling the dried non-woven fabric base material to obtain the self-adhesive elastic bandage. Through sizing and coiling of the non-woven fabric base material, the elastic and self-adhesive non-woven fabric bandage is obtained; the production process and equipment structure are simple; and the material cost and the process cost are reduced.

Description

technical field [0001] The present application relates to the medical field, in particular to a method for manufacturing a self-adhesive elastic bandage and the self-adhesive elastic bandage. Background technique [0002] Self-adhesive elastic bandage itself has certain viscosity and elasticity. In the medical field, it is usually used for dressing fixation of special parts, burn and postoperative pressure bandage, and bandage protection for vulnerable parts during exercise. Self-winding and fixing are convenient, good elasticity, good air permeability, strong compliance, etc., so it is widely used. [0003] The base material of the self-adhesive elastic bandage is usually a fabric with certain elasticity such as non-woven fabric. However, due to the poor elasticity and self-adhesiveness of the non-woven fabric itself, most self-adhesive elastic bandages based on non-woven fabrics use spandex yarns to be woven into the non-woven fabric base material to make the non-woven fa...

AI Technical Summary

Problems solved by technology

However, due to the poor elasticity and self-adhesiveness of the non-woven fabric itself, most self-adhesive elastic bandages based on non-woven fabrics use spandex yarns to be woven into the non-woven fabric base material to make the non-woven fabric base material elastic. effect, and then make the non-woven fabric substrate self-adhesive by coating the viscose fiber agent, so as to obtain a self-adhesive and elastic bandage

However, the self-adhesiveness and elasticity of this self-adhesive elastic bandage are mainly derived from additional materials, specifically, for example, by adding spandex filaments in the non-woven fabric base material to make the non-woven fabric base material elastic, The viscose fiber agent is coated on the cloth to make the non-woven fabric substrate sticky. Therefore, the process is relatively complicated, resulting in relatively high costs for materials, equipment and processes
