Physical Chemistry of Crosslinking
Cotton fabrics were treated with different crosslinking agents under conditions found to be most favorable for chemiscrption of crosslinking molecules on cotton fibers. The effects of various factors such as period of chemisorption, temperature of drying and curing, concentration of crosslinking agents, pH, and nature of the catalysts on the physical properties of fabrics were investigated. The results show that chemisorption for a period of one hour is sufficient. Drying alone produces inferior properties of the fabrics compared to the fabrics which have been dried and cured. The results also indicate that the physical properties of the treated fabrics in the presence of sodium chloride are better than those obtained in the presence of magnesium chloride.
