Abstract
Direct dyes represent one of the cheapest and the simplest dyeing systems usually require only an electrolyte for their application. They are widely used in the textile industry because they are cheap and the only problem is their fastness properties that were solved in this research. Different techniques have been developed to enhance their fastness properties, one of them being the use of a cationic dye fixing agents. Bleached jute fabrics were dyed with direct dye before and after the treatment of cationizing agents and their properties are compared. It was found that in terms of fabric rubbing fastness, washing fastness and K/S value, cationization after dyeing is superior to cationization before dyeing.c
Highlights
Jute fiber consists of strands i.e., bast bundle fiber assemble in parallel manner with overlapping to produce filaments throughout the length of the stalk
It can be noticed that both dry and wet rubbing fastness of cationizing agent apply before dyeing are poor in comparison to cationizing agent apply after dyeing
It can be noticed that washing fastness of cationizing agent apply before dyeing is poor in comparison to cationizing agent apply after dyeing
Summary
Jute fiber consists of strands i.e., bast bundle fiber assemble in parallel manner with overlapping to produce filaments throughout the length of the stalk. Evolution of hydrogen sulphide gas under anaerobic conditions when sodium sulphate is used as electrolyte Dissolution of such sulphide and subsequent bacterial oxidation to harmful sulphuric acid [5]. To overcome these problems and improve the dye ability of fabric the surface modification of fabric is done. The fabric become cantonized and has columbic attraction between cationic fabric surface and anionic dyestuff This cantonized fabric can be dyed without the use of electrolyte (Table 2) [6]
