Abstract

The invention discloses an aqueous polyurethane coating label tape and a preparation method thereof, wherein the label tape includes a base cloth layer and a coating layer which coats both the front surface and the back surface of the base cloth layer. The base cloth layer is formed by warp yarns and weft yarns through warp-inlaid knitting, wherein the warp yarns are 75D polyester filament yarns and are 41 / cm in density, and the weft yarns are 100D polyester filament yarns and are 26 / cm in density. In the invention, the base cloth layer is knitted by the polyester filament yarns of which the cross sections are hollow, so that the label tape can absorb ink better, is increased in print definition, is excellent in printing performance, is dyeing-resistant, is good in washing resistance, is free of loosen edge, can completely satisfy print requirement and functional characteristics of a product and is low in cost. The coating layer is formed by the aqueous polyurethane coating which is toxic-free, environment-friendly and wear-resistant and is high in thermal stability. The coating label tape is smooth and flat in surface, is enhanced in absorption of printing ink and allows label printing to be clear.

Description

【Technical field】 [0001] The invention relates to the technical field of trademark tape, in particular to the technical field of water-based polyurethane coated trademark tape and its preparation process. 【Background technique】 [0002] The finishing methods of denim casual clothing include stone grinding, and then water washing, sand washing, soft washing, etc., which put forward higher requirements for auxiliary materials such as clothing labels: in addition to achieving normal printing effects on the label substrate , but also have other properties, such as resistance to staining, sand washing and so on. If the color of colored clothing is dyed on the label cloth during sand washing, enzyme washing, etc., the printed data on the label will be blurred and the barcode will not be read. For this reason, it is necessary to develop a kind of anti-staining polyurethane coated label tape product. 【Content of invention】 [0003] The purpose of the present invention is to solv...
