A kind of manufacturing method of non-woven needle-punched adhesive tape substrate

Abstract

The invention discloses a manufacturing method for a non-woven needling adhesive tape substrate. The method comprises the following steps: mixing 80-95 percent by weight of regenerated polyester fiber and 5-20 percent by weight of low-melting-point chopped fiber serving as raw materials; mixing, opening, feeding, carding into a net, lapping and needling to form a non-woven cloth layer; and performing hot rolling treatment and calendaring treatment on the non-woven fabric layer to obtain the non-woven needling adhesive tape substrate, wherein the liner density of the regenerated polyester fiber is 0.9-2.0D, and the fiber length is 36-51 millimeters; and the linear density of the low-melting-point chopped fiber is 1.0-3D, the fiber length is 38-51 millimeters, and the gram weight of the adhesive tape substrate is 50-80 g / m<2>. According to the method, the tearing property of the entire adhesive substrate can be realized, and the non-woven needling adhesive tape substrate has the characteristics of freeness from burrs and high surface flatness.

Description

technical field [0001] The invention relates to the field of nonwoven materials, in particular to a method for manufacturing a nonwoven needle-punched adhesive tape substrate. Background technique [0002] Conventional tapes, such as adhesive plasters, dressing supplies, and surgical cloths, are packaged in rolls, and people need to tear the tapes into smaller strips to meet actual use needs. Generally, it sticks to the skin for a long time, so it may cause rashes, skin allergies, etc. At present, the improvement of adhesive tapes is generally such as air permeability and other issues, such as Chinese patent publication CN101929079A, which relates to the manufacture of medical air-permeable adhesive tape substrates method. No in-depth research has been conducted on the molding process of the adhesive tape, but the applicant has concentrated on research on the molding method of the easy-to-tear adhesive tape, and this case arose from this.
