Recent Observations on Preparation of Novel Chitosan-Starch Blends as a Multi-function Thickening Agent and Their Application in Textile Printing

Chitosan was blended with different ratios of gelatinized starch, a naturally available biopolymer which is now increasingly used as a functional finish on textile substrates to impart antimicrobial characteristics and increase dye uptake of fabrics. Chitosan e was extracted and defined by the position of the IR, H-NMR, and X-ray powder. In textile screen printing, these blends have been tested as thickeners using Curcuma tinctoria as a natural dye. e rheological properties and the viscosity of the printing paste were measured. By measuring the colour strength value (K / S) and related colour parameters of the printed fabrics, the effect of chitosan on the printing properties of different fabrics (natural, blended, and synthetic fabrics) was studied. The antimicrobial properties of printed textiles have been evaluated. THE The results showed that the printed fabrics using these new thickeners showed an increase in the colour strength value (K / S) giving darker colour, which means that the dye uptake on fabrics was increased by chitosan. Strength characteristics of the printed fabrics have also been improved to washiftng, rubbing, sudor, and light. These blends were also used as a multi-functional thickener by adding chitosan to gelatinous starch to act as an antibacterial agent, binder, and improve the pigment printing properties of various fabrics. The fabrics treated were found to be antimicrobial.
