Abstrak
Reactive dyes are dyeshtffs that can reactwith cellulose or proteiru It has small molecular weight, water soluble and binds covalently to the fiber and provives good calourfastness on washfastness and perspiration resistance. Mainly leather for garment is dyed using aniontc dyeinffs, but the use of reactive dyes is not commonfor leather dyeing. In the present study, an atternpt the use of reactive dyes with variation concentration of 10, I 5 and 20 %. The aim of the research was to determine the fficts of using reactive dyes on colourfastness and morphologt tilapia skinfor garment leather The raw material in this research were wet salted tilapia skin. The test parameters were washfastness and perspiration resistance and visual test on microscopic of collagen f.ber. The results showed that the use of reactive dyes affected on washfastness and perspiration resistance. The best concentration of reactive dyes was 15 96 and gave better washfastness and perspiration resistancewith the value of 5.
