Air-permeability cotton cloth medical adhesive tape and manufacturing method thereof

Abstract

The invention discloses an air-permeability cotton cloth medical adhesive tape and a manufacturing method thereof. The adhesive tape is manufactured by coating a hot melt adhesive or zinc oxide hot melt adhesive layer only on one side of cotton cloth and cutting the cotton cloth into segments, and is characterized in that: hot melt adhesive is coated on the side of the cotton cloth at intervals in a strip way and the intervals between the adhesive strips, which are not coated with adhesive, are 1 to 5 millimeters wide. The width of adhesive parts of the cotton cloth medical adhesive tape is equal to or more than that of the adhesive-less parts. The method of the invention greatly improves the air permeability of the cotton cloth medical adhesive tape by coating the adhesive in a strip way, so that a user is protected from allergy.

Description

technical field [0001] The invention relates to a manufacturing method of a medical adhesive tape, in particular discloses a breathable cotton medical adhesive tape and a manufacturing method thereof. Background technique [0002] Hot-melt adhesive cotton medical tape is a kind of adhesive tape used in surgical operations, fixing dressings or catheters, etc. It can also be used for sports protection, labor protection and industrial packaging. The utility model has the advantages of firm fixing, strong applicability and convenient use. The manufacturing method of the tape is that one side of the cotton cloth is surface-treated by the cotton cloth manufacturer or the manufacturer of the cotton medical tape, so that the cotton medical tape can be unrolled easily; the other side of the cotton cloth is coated with a layer of high-strength hot melt Glue or zinc oxide hot melt adhesive, cut into tapes. The edge of the tape is cut into a serrated edge or a straight edge, and the s...

Problems solved by technology

However, the cotton medical tapes on the existing market are all coated with solvent-based pressure-sensitive adhesives or hot-melt pressure-sensitive adhesives by transfer coating, so the air permeability is very poor.

Although the hot melt adhesive can be directly coated, due to the large amount of glue applied and the thick glue layer, even if there is air permeability in the end, it is very limited. If it is pasted on human skin, it will be prone to allergies due to airtightness.
