In contrast to woven fabrics, knitted fabrics allow higher productivity, lower production costs and investments, better comfort and hand properties, along with higher extent of penetration due to low twist of yarns and open structure.
Recently, functionalization of cellulosic fabrics , full white and colored, using appropriate finishing formulations and conditions has become more demanded to impart and/or develop innovative textile products, taking in consideration the quality, environmentally as well as economic concerns.
The original work presented in this thesis was undertaken with a view to search for the proper finishing formulations and conditions for producing high quality knitted cotton fabrics with remarkable functional properties.
To achieve the above mentioned tasks, the following studies were carried out:
I- Improving the quality and functionality of knitted cotton fabrics
II- Upgrading the functional properties of reactive dyed cotton knits.
In this study, three different reactive dyed single jersey cotton knits produced from different yarn counts, i.e., Ne 20/1, Ne 24/1, and Ne 30/1 were selected for studying the impact of functional finishes, i.e., soft, bio-antibacterial, and water-repellent, on their performance and comfort-properties. It was found that the variation in the evaluated properties is very much dependent on the yarn count as well as on the type and concentration of the finishing agent. An improvement in pilling levels and tactile properties, i.e., smoothness and softness, as well as in
comfort properties, i.e., heat transmittance, air permeability as well as waterabsorption, is achieved by the bio-treatment. An enhancement in dimensional stability, pilling levels, bursting strength, tactile properties along with a reasonable improvement in antibacterial efficiency is obtained by soft-finishing, taking in consideration its tendency to entrap heat and air inside the fabric structure. The same holds true for water-repellent treatment, in addition to its outstanding
