Weak solvent or offset printing thermal transfer paper and production process thereof

Abstract

The invention relates to a weak solvent or offset printing thermal transfer paper. The thermal transfer paper from bottom to top is provided with a paper base, a first thermal transfer adhesive layer and a weak solvent or offset printing absorption dielectric layer. The first thermal transfer adhesive layer comprises the following components, by weight: 40-50% of polycaprolactone polyurethane, 30-40% of butadiene styrene or styrene copolymer, 10-15% of copolymerization polyamide resin, 5-10% of copolyester resin and 2-5% of pentaerythritol ester of rosin. At the same time, the invention also relates to a corresponding production process. According to the invention, the drew image can be freely printed by a weak solvent inkjet printer, a solvent-type ink-jet printer, a digital printing machine and a digital label printing machine, and then transferred to any textile through a hot pressing tool; a textile pattern can be finished in a few minutes, so as to fully meet the needs on small batch and rapid production by thermal transfer printing; and the production process has advantages of low labor intensity, high production efficiency, energy saving and environmental protection.

Description

technical field [0001] The invention relates to a weak solvent or offset printing heat transfer paper and a manufacturing process thereof, belonging to the field of heat transfer materials. Background technique [0002] The process of traditional screen printing T-shirts and bag box printing is as follows: making pictures - Feilin film - making screen version - proofing board - proofreading samples - silk screen printing - production - thermal transfer printing - complete; therefore , using the traditional printing T-shirt and bag box printing process, can solve the requirements of simple and mass production, but at the same time, its long process flow, large number of personnel, and insufficient exquisite products make it impossible to print in small batches and quickly Production, product diversification, and personalization meet market demand, but labor costs are high, production efficiency is low, and energy conservation and environmental protection are not enough. The s...
