dc.description.abstractCarboxymethylcellulose salt occurs as a white or slight yellow flocculent fiber powder or white powder which is non-toxic, tasteless, odorless and easy to dissolve. It has a thickening, emulsifying, shaping, water retention, stabilizing capacity, and becomes colourless when dissolved in cold or hot water. Carboxymethylcellulose has found a wide use in textile industry for textile surface treatment. It has gained an advantage over starch as a sizing agent for cotton yarn since it enables a smooth surface. This work discusses the use of CMC to modify the surface of polyester fibers.The topochemical modified polyester fibers are improved by the the crosslinking of polyester fibers with carboxymethylcellulose resulting in a better water absorption capacity of the polyester fibers since the polyester fibers are well known for their hydrophobic character. The overall objective of this research is to observe and determine the best crosslinking temparature and crosslinking time of the carboxymethylcellulose onto the polyester textile substrate and also to observe the maximum water absorption capacity of the treated fabric. The oven as well as the special heating vials with lids were used to perfom the whole experiments to try and accomplish the whole task of this research.cs
