自制烫金用WPU的配方调控对图案精细度及牢度的影响
Effects of Formula Regulation of Self-made WPU for Bronzing on Pattern Fineness and Fastness
摘要
Abstract
In order to solve the problem of pattern poor washing and rubbing fastness of waterborne polyure-thane(WPU)adhesives in bronzing processing,the performance of self-made WPU was optimized by adding thickener and crosslinking agent.The effects of thickener and crosslinking agent on the viscosity,water contact angle,water absorption,tensile strength,elongation at break and peel strength of WPU adhesive were investiga-ted.The optimized adhesive formula was applied to bronzing processing technology.The results showed that the viscosity of WPU was adjusted by adding thickener.The addition of isocyanate crosslinking agent increased the water contact angle of the film,decreased the water absorption,and improved the tensile strength and the peel strength.The amount of thickener was 0.6%and the amount of crosslinking agent was 4%.The bronzing fabric processed with this formula had good pattern fineness,and the friction 1500 r pattern was still intact.The fastness could still maintain at level 4 after washing,and its performance index was comparable to that of the bronzing fab-ric processed with solvent-based adhesives.关键词
