Textile printed ribbon

Abstract

The invention discloses a textile printed ribbon. The textile printed ribbon comprises a base fabric and a coating on the surface of the base fabric, wherein the coating comprises a polyurethane adhesive layer clung to the upper surface of the base fabric and a polyurethane finishing layer on the upper surface of the base fabric, a polyurethane adhesive is prepared from a polyurethane emulsion, an antistatic agent, a thickening agent, a flatting agent and an auxiliary agent, and a polyurethane finishing agent is prepared from a solvent, polyurethane resin and an auxiliary agent. The textile printed ribbon disclosed by the invention has the characteristics that the polyurethane resin is used as a main ingredient of the coating, great adjustability of the mechanical properties of the polyurethane resin is utilized and the relevant functional auxiliaries are added for blending modification, so that the polyurethane barcode printed ribbon has the advantages of antistatic (accumulation) property, dry and wet friction resistance, blocking resistance and scratch resistance to the polyurethane coating film, as well as no toxicity, environmental friendliness, flexibility, elasticity and high heat stability.

Description

technical field [0001] The invention relates to a polyurethane bar code printing belt. Background technique [0002] With the application of barcode printing technology and equipment, it has caused great changes in the field of printing materials. In the past, paper and nylon-coated printing materials, due to the former's high water absorption, poor surface smoothness and poor finish, would cause unclear handwriting and broken barcodes during printing, so it was only suitable for wet ink printing; dry ink The (barcode) printing process is different from the wet ink printing process. The ink printed by wet ink is liquid and has good leveling property; while the dry ink is attached to the tape, and is transferred from the tape to the printing material by low pressure and low temperature during printing. Therefore, the requirements for the surface finish of the printing material carrier are relatively high. Once there are uneven spots on the surface of the coating, it will cau...

In the past, paper and nylon-coated printing materials, due to the former's high water absorption, poor surface smoothness and poor finish, would cause unclear handwriting and broken barcodes during printing, so it was only suitable for wet ink printing; dry ink The (barcode) printing process is different from the wet ink printing process. The ink printed by wet ink is liquid and has good leveling property; while the dry ink is attached to the tape, and is transferred from the tape to the printing material by low pressure and low temperature during printing. Therefore, the surface finish of the printing material carrier is highly required. Once there are uneven spots on the surface of the coating, it will cause unclear handwriting, and the end face of the barcode cannot be quickly, timely and accurately collected and stored by the code reader. , Processing digital information, unable to transfer the numbers to the digital library in time, and implement electronic data exchange

[0003] During the printing process of nylon-coated printing materials, the friction between the material and the equipment or the induction of static electricity will cause the printing materials to generate static electricity. Irregular and garbled codes increase the labor intensity of the operator and reduce the production efficiency. Moreover, nylon has a low heat distortion temperature and poor dimensional stability. When the material is cut, the layers will adhere to each other. Dimensional deformation, in severe cases cannot be separated and scrapped
