Adapting the principle of neutral sulphite cooking for modification of textile quality of jute fibre

Abstract

A study is reported on the modification of textile properties of jute fibre by treatment with neutral sodium sulphite liquor at varying temperature under pressure. The lignin of the fibre undergoes a sulphonation reaction and is partially dissolved out from the fibre along with some hemicelluloses depending on the degree of sulphonation. The residual lignin sulphonates probably form insoluble condensation products in the fibre. The treatment brings some changes in the physicochemical properties of the fibre. The modified jute fibre may be utilized in fine yarn spinning for diversified textile uses.
