Embodiment 1

[0023] Example 1: Effects of Fibers of Different Lengths on Moisture Release and Breathability

[0024] In this embodiment, the medical dehumidifying breathable dressing is combined with figure 1 , comprising a base material 1 and a composite adhesive layer 2 positioned on the base material 1, wherein the composite adhesive layer 2 is composed of an adhesive body 21 formed of an adhesive and fibers 22 mixed in the adhesive body 21, and the fibers 22 are evenly distributed In the adhesive body 21, in this embodiment, the self-produced ZDS-005 pressure-sensitive adhesive is selected as the adhesive, the self-produced purified water is selected as the soaking agent, and long-staple cotton is selected as the fiber 22. figure 1 The shown is set through the adhesive body 21, and the longer fibers 22 are exposed on the surface of the adhesive body 21, and lie on the upper surface of the adhesive body 21, and the addition percentage of the fiber in the composite adhesive layer is 30%....

Embodiment 2

[0033] Example 2: Effect of Fiber Addition on Moisture Release and Air Permeability

[0034] In this embodiment, the medical dehumidifying breathable dressing is combined with figure 1, comprising a base material 1 and a composite adhesive layer 2 positioned on the base material 1, wherein the composite adhesive layer 2 is composed of an adhesive body 21 formed of an adhesive and fibers 22 mixed in the adhesive body 21, and the fibers 22 are evenly distributed In the adhesive body 21, in this embodiment, the self-produced ZDS-005 pressure-sensitive adhesive is selected as the adhesive, the self-produced purified water is selected as the soaking agent, the long-staple cotton is selected as the fiber, and the mass percentage of the fiber added to the composite adhesive layer is gradually increased .

[0035] The processing technology of the above-mentioned dressing is as follows: fiber crushing→soaking→adhesive modification→coating→glue forming→dressing forming.

Abstract

The invention relates to a medical moisture-removing permeable dressing and a processing technology thereof, and belongs to the technical field of surgical supplies such as medical transparent dressings, applications, medical adhesive tapes and adhesive bandages. The medical moisture-removing permeable dressing comprises a substrate, a compound adhesive layer and a release protection layer, the compound adhesive layer is positioned on the substrate, the release protection layer is positioned outside the compound adhesive layer, the compound adhesive layer comprises an adhesive body formed by an adhesive and fibers mixed in the adhesive body, the fibers are uniformly distributed in the adhesive layer, and the length of each fiber is 25-35 micrometers. The dressing prepared by the processing technology has the advantages of better moisture-removing performance and permeability.

Description

technical field [0001] The invention relates to a medical moisture-expelling breathable dressing and a processing technology thereof, belonging to the technical field of medical transparent dressings, applicators, medical adhesive tapes, bandages and other surgical supplies. Background technique [0002] Dressing is a kind of surgical supplies commonly used in medical work and nursing treatment. It usually includes base material, adhesive layer and release protective layer from outside to inside. The adhesive layer mainly plays the role of bonding and fixing. The conventional adhesive layer is made of adhesive, and the conventional adhesive layer is not good in breathability and moisture permeability. A layer of isolation layer is formed between the medical dressing product and the skin, and a complete isolation is formed between the skin and the air. The introduction of external bacteria, but because it affects the moisture permeability and air permeability of the dressing ...
