Abstract

Lignin a natural source which is abundant, has a complex structure that doesn't allow water to escape outside and this paper investigate the possibility of extracting and coating of lignin in an eco friendly approach on textile materials. Laccase enzyme was extracted from Pleurotusostreatus mushroom showed an activity of 2.2. Enzymatic extraction of lignin from sugarcane bagasse and coir fibre was done, the amount of lignin isolated was 19% and 25.5% respectively. The extracted lignin was coated on 100% cotton and silk fabrics by pad-dry-cure process. Three different composition of cross linking agents and extracted lignin were taken and out of which 1% glutaraldehyde, 10% gelatine and 84% lignin showed effective spray rating test result of 80. The SEM analysis of the cotton and the silk fibre reveals that the water proof coating is uniform in cotton than that of the silk fabric.
