[en] Two factors of coating process of 100% polyester fabric with irradiated natural latex which content 10 phr (part hundred ratio of rubber) of isocianate i.e. time curing of 1, 1.5, 2, 2.5 minutes and total number of coating 1, 2, 3 times have been carried out. The importance properties of raining coat i.e. percentage of water absorption, hydrostatic pressure and pull strength have been evaluated. The results showed that by increasing of curing time and number of coating the hydrostatic and pull strength of polyster coated fablic increases, and the percentage of water absorption decrease. The polyster fabric coated by irradiated natural with the film thickness of 40 micron (two times coating), and the curing time of 2.5 minutes at 150 Celcius centigrade, can produce raining coat fabric as well as required.
