Description

Technical field [0001] The invention relates to the technical field of luggage inks, and specifically to a special ink for luggage and a printing method thereof. Background technique [0002] Luggage is a general term for bags, which is a general term for various bags used to hold things, including general shopping bags, handbags, clutches, wallets, backpacks, shoulder bags, shoulder bags, waist bags and various trolley cases, etc. . [0003] Ink is an important material for printing. It displays patterns and text on the substrate through printing or inkjet. The ink includes the main components and auxiliary components, which are uniformly mixed and rolled into a viscous colloidal fluid. It is composed of binder (resin), pigments, fillers, additives and solvents. Used for various printing of books, packaging and decoration, architectural decoration and electronic circuit board. With the increase in social demand, the variety and output of ink have expanded and increased accordi...

AI Technical Summary

Problems solved by technology

[0004] Luggage printing ink process is to print the ink on the surface of the formed luggage, spray varnish after the ink is dry to form a protective layer, to prevent the ink from being corroded by moisture in the air or external acid and alkali, and also increase the wear resistance of the pattern. The pattern printed by the ink will not be deformed and faded for a long time, but the processing technology is cumbersome, the processing cycle is long, and the top coat is easy to fall off, which requires high requirements for the operator, and the surface of the bag is easy to scratch

[0005] In addition, the existing luggage inks are basically the same as ordinary inks, with low performance and few bright spots, resulting in insufficient competitiveness of printed luggage and unsatisfactory sales. After printing ink, the luggage has a strong smell, and it is prone to problems such as fading and short life.

[0006] In the patent document with the publication number CN102952430A, a special ink for luggage is disclosed. The special ink for luggage includes the following components in parts by weight, pigment 15%-25%, polycarbonate 25%-35%, environment-friendly polycarbonate Carbonate binder 30%-50%, desiccant 5%-12%; the special ink for bags designed by the present invention is not easy to fade and fade; used in the printing process of bags, due to the good connectivity of the ink, it can absorb plastic at high temperature The graphics can be stretched at any time without causing cracking and deformation of the graphics; the bags made by this technical scheme are beautiful and practical, the bags are wear-resistant, will not fade and fade, and are environmentally friendly; but the ink has few characteristics and wear resistance still not enough
