Absorption of Basic Dyes by Jute

Abstract

IT is well known that jute fibre has a strong natural affinity for basic dyes. This was formerly ascribed to the presence of tannins in the fibre1. Analysis of a fairly large number of jute samples of different qualities in this Laboratory has shown that though the plant contains some tannin, the retted fibre is practically free from it. According to Chowdhury and Mitra2, acid constituents of the fibre, such as uronic acids, are responsible for this affinity. Some attribute it to the presence of lignin in the fibre. According to Parsons8, for example, “delignified jute no longer has this property”. The same statement also occurs in the latest edition of Whit taker's book4. Correct information in this regard is very important from the industrial point of view, for basic dyes are extensively used in dyeing jute, and if lignin be really the cause of absorption, fully bleached jute would not take up the dye unless mordanted.
