In April 2016 Manchester eScholar was replaced by the University of Manchester’s new Research Information Management System, Pure. In the autumn the University’s research outputs will be available to search and browse via a new Research Portal. Until then the University’s full publication record can be accessed via a temporary portal and the old eScholar content is available to search and browse via this archive.

Abstract

This research investigated the possibility of improving the dyeability of fabrics made from polyester and cotton by using chitosan surface treatments. A pad-cure-dye process was used as this avoids using harmful chemicals and is cost effective. The work was extended to study the application of chitosan on poly/cotton blended fabrics to improve their dyeability and printability. The chitosan treatment used was a pad-cure-dye process that enabled the dyeing of blended fabrics using one dye bath containing commercially available acid dyes. The research findings showed that it was possible to use a chitosan surface treatment to improve the dyeability of polyester, cotton and poly/cotton blended fabrics using a single dye bath technique in a cost effective and eco-friendly way. After investigating the possibility of applying chitosan to improve the dyeability of the studied fabrics, the work was extended to study the use of chitosan in the differential printing of polyester, cotton and two sets of poly/cotton blends. This was achieved by applying chitosan as a non-coloured paste to the fabrics. It was found that areas treated with chitosan attracted more dyestuff than the rest of the untreated fabric. Using this technique, a printed design of two shades was obtained using a single dye bath. This technique would be useful when designing multi-shaded fabrics using one colour. This also enables clothing and textile factories to quickly respond to market changes in one season, i.e. a stock of printed textiles with clear chitosan could be prepared and stored to be dyed with the required colour when stock is running low. After demonstrating the possibility of dyeing polyester and poly/cotton blends with acid dyes, the research studied the possibility of resist printing polyester and poly/cotton blended fabrics using chitosan using commercially available acid dyes. The findings provided great results indicating the possibility of resist printing polyester and poly/cotton fabrics without the need of applying specially synthesized dyes or hazardous chemicals.
