ABSTRACT

S-Finish: A term originally applied to the partial surface saponification. A term originally applied to the partial surface saponification of cellulose ester fibres (acetate and triacetate) by alkaline hydrolysis to reduce static charge and improve fabric handle. Alkali treatment of polyester. Nowadays the term has also been adopted for an analogous treatment of polyester fibres in which a controlled partial saponification with alkali (NaOH) is carried out to achieve a silk-like lustre and handle, reduce the buildup of static charges and improve anti-soil properties.
