preparation example Construction

[0023] A preparation method of a synthetic glue three-layer composite non-woven self-adhesive elastic bandage, comprising the following steps:

[0024] 1) Add a certain thickness of impregnated non-woven elastic fabric into elastic spandex yarn through the stitch-bonding process to form a stitch-bonded impregnated non-woven elastic fabric base material;

[0025] 2) The two-layer stitch-bonded and impregnated non-woven elastic fabric base material is wrapped with a certain thickness of non-elastic hot-rolled non-woven fabric through the composite process, and a protein-free composite adhesive is used to form a synthetic three-layer composite non-woven fabric. Fabric substrate for viscoelastic bandages;

[0026] 3) after coating the latex-free synthetic glue on the cloth base material for drying, the semi-finished product of the synthetic glue three-layer composite non-woven self-adhesive elastic bandage is obtained;

[0027] 4) The semi-finished product is processed according ...

Embodiment 1

[0029] 1) Production preparation

[0030] a. Prepare the base material of the bandage, which is two layers of impregnated non-woven fabric and one-time hot-rolled non-woven fabric;

[0031] b. Prepare the composite adhesive for the base material of the bandage, which has no protein component;

[0032] c. Prepare the latex-free synthetic glue for bandage products;

Abstract

The invention discloses a synthetic adhesive three-layer composite non-woven self-adhesive elastic bandage which is prepared from composite cloth base material and protein-free composite adhesive through coating synthetic adhesive, and is prepared from two layers of seam-knitted impregnated non-woven elastic cloth wrapped with one lay of non-elastic hot-rolled non-woven cloth. The invention has certain tensile strength, better self-adhesive strength, better elasticity, high temperature resistance, better sweat absorption ability and better soft touch.

Description

technical field [0001] The invention relates to the application field of elastic bandages, in particular to a synthetic bandage with certain tensile strength, better self-adhesive strength, better elasticity, high temperature resistance, better sweat absorption ability, better soft touch feeling and certain aesthetic effect. An adhesive three-layer composite non-woven self-adhesive elastic bandage and a preparation method thereof. Background technique [0002] With the constantly changing market demand, self-adhesive bandages with fixed protective effect, good self-adhesion and wrapping are recognized by more and more consumers. However, conventional self-adhesive bandages, on the basis of certain tensile strength, self-adhesive strength and elasticity, do not have good high temperature resistance, good sweat absorption, and good soft touch, and conventional self-adhesive bandages They are all protein-containing products, which may cause allergic reactions to human skin. ...
