A study of selected chemical treatments on cotton fabrics for improving functional finishing effect

Abstract

The increase in technologies has witnessed a number of advances in the textile industries especially for medical and hygienic uses Chemical treatment of cotton cellulose to alter physical properties of the fibers without newlinechanging their fibrous form is a common practice in the textile industry to newlineachieve the desired finishing effects Cotton is considered as the king of the newlinetextile fibers based on its overall properties suitable for the end use products newlineTo enhance the functional properties of the cotton fabrics it is essential to newlinetreat them with the suitable chemicals without reducing the needed aspects of newlinethe materials Hence in this research work it was decided to treat the cotton newlinefabrics with suitable chemicals so as to receive the functional characteristics newline100 percentage woven and knitted cotton fabrics were selected and treated with i newlinesodium hydroxide of 15 percentage owm ii morpholine 40 percentage wv and iii newlinecellulase enzyme 4 percentage owm concentrations respectively These treated newlinefabrics were then subjected with chitosan of 2 percentage owm concentration newlinefollowed by natural 25 gpl and synthetic 2 percentage owm dyeing The treated newlineand finished fabrics were then tested suitably for the necessary aspects newlineThe physical properties of treated cotton woven and knitted newlinefabrics sodium hydroxide treated morpholine treated cellulase treated and newlineuntreated dyed with annatto onion pomegranate indigo myrobalan barberry reactive dye and sulphur dyes are good and are within the tolerance newlinelimit The drop absorbency of cotton these treated fabrics dyed with annatto newlineonion pomegranate indigo myrobalan barberry reactive dye and sulphur newlinedyes is goodThe cotton fabrics after treatment with the chemicals sodium newlinehydroxide morpholine and cellulase enzyme when applied with chitosan newlinefollowed by dyeing the overall absorbency is increased considerably newlineparticularly in the sodium hydroxide treated one newline newline
