Impact of Modified Glyoxalic and Co-polymer Acrylic Crosslinkers Effect on the Crystallinity and Mechanical Properties of Finished Cotton.

This paper presents the impact of modified glyoxalic (DMDHEU) and co-polymer acrylic crosslinkers effect on the Crystallinity, Crystallite Size and mechanical properties of finished cotton. Using a modern technical analysis is very significant to describe the outside modification of cellulose fiber and the inside of crystalline region. The obtained results make clear the morphology cross-linking aspect after the treatment of resin with the previously cited Crosslinkers. Benchmarking the effect of used Crosslinkers at various finishing conditions (curing temperature, curing time, drying temperature, drying time and crosslinkers concentration) on crystallinity, crystallite size and surface morphology of finished cotton, is the answer of durable press application problems. It inspects the modified glyoxalic crosslinkers upshot more than acrylic crosslinkers on mechanical properties of cotton yarns. It proves that crystallinity index and crystallite size distinction of treated cotton have a way to link with cellulose physical properties, such as the ability to cross-link in amorphous region. The results also describe the effect of two crosslinkers on the fall mechanical properties of treated cotton. They show an important change on retention of breaking strength and elongation, creep and relaxation rate of treated cotton.
