Abstract:
In this research into the process of dyeing polyester/cotton fabrics using disperse/reactive dyestuffs in one method dyeing processes. . In the order to improve the adhesion of chitin to the surface of polyester/cotton fibers, pre-treatment in NaOH solutions was performed. The colour and rubbing fastness properties of the chitin-deposited polyester/cotton fabrics were assessed. The colour difference between the dyed blank samples and samples dyed in after NaOH and/or different viscosity chitin treatment was estimated using spectrophotometer evaluation. The data obtained shows that it is possible to dye polyester/cotton fabrics finished by chitin with only one disperses/reactive dyestuff, which normally shows substantively to cellulose fibers. The dyed samples showed good rubbing and washing colour fastness properties within the range of colour change. The colour strength of the dyed samples increased with the increased deposition of chitin on the fabric.
