Abstrakt: In order to synthesize ultraviolet absorbent with strong ultraviolet absorption property, a novel anti-ultraviolet finishing agent was synthesized by the esterification reaction of DL-malic acid and 3,4, 5-trimethoxycinnamic acid and its structure of which was confirmed by mass spectrometry. The anti-ultraviolet agent was al)Plied to the PET fabric by the pad-dry-cure process. The finishing recipe and condition were optimized by investing the finishing effects to anti-ultraviolet. The results show that the optimum process conditions are as follows: absorbent concentration 10 g/I.. drying temperature 65 'C and baking temperature 160 "C. After finishing. the ultra-violet protection factor (UPF) of the fabric increased from 35.18 to 83.95 and no significant mechanical lose. After 30 laundry cycles. the finished fabric's UPF value slightly declined.which indicats the excellent durability of the anti-ultraviolet agent. [ABSTRACT FROM AUTHOR]
