Dyeing and Anti-Microbial Finishing of Jute Using Natural Bio-Polymer and Pharmaceutical Drugs
The unimolecular structure of chitosan imparts extremely high affinity for many classes of dyes including
disperse dye, reactive dye, direct dye, vat and Sulphur dyes etc. Sorption of chitosan is exothermic: hence an increase in dye
temperature leads to an increase in dye sorption. At lower pH chitosan free amines protonated causing to attract anionic
dyes.Due to the Antimicrobial action of the amino group at the C-2 position of the glucosamine residue, chitosan is also
known to be an antimicrobial polysaccharide. The ability of chitosan to immobilize microorganisms derives from its
polycationic character. Its protonised amino groups block the protein sequences of microorganisms, thus inhibiting further
Tetracycline, common and cheap antibiotic drug is used against many bacterial infections. Taking outdated tetracycline (an
antibiotics) can cause serious side effects. Expired Tetracycline was known to be responsible for kidney impairment.
Discarding unused, outdated or expired tetracycline hydrochloride in the toilet is a common practice. But this method may
not be any safer than throwing in the trash, because it still is contaminating water supply.
The present work deal with a natural bio-polymer like chitosan to be used for disposal of harmful antibiotic like TCH which
can be recycled and used in textile wet processing. The product prepared by mixture of chitosan and TCH was used to finish
many textile substrates to give value added finishing like anti-microbial finish.
