Surface modification of polyester is well known to a chemical processing man by weight reduction process. The treatment will impart comfort characteristics to polyester and also the treatment has proved as replacement for silk.
This study deals with pre-treatment of polyester with swelling agent followed by alkaline hydrolysis. Glycerine was selected as pre-treatment solvent with 15%and 25% concentration treated at 60C. Pre-treated materials were base hydrolysed at 130
Warp and weft bending length has registered a decreasing trend in the glycerine-treated samples at 60c and alkaline hydrolysis at 130
Sharp rise in GSM following pre-treatment and hydrolysis (Glycerine per-treatedsamples) have indicated the action of glycerine on PET.
Crease recovery in warp and weft has registered the increasing trend with concentration and temperature of pre-treatment and hydrolysis at higher levels.
