COMPOSITION OF CARBOHYDRATES IN FRESH WHEY — Proceeding R-1

Apstrakt

Desizing of cotton fabric is a vital step in textile wet processing, directly influencing subsequent treatment and overall fabric performance. This study evaluates the effectiveness of hydrochloric acid, ammonium persulfate, and thermostable amylase asdesizing methods.. The performance of each method was assessed through key parameters: change in fabric mass, water penetration time, water absorption capacity, breaking strength, elongation at break, and air permeability. The results indicate distinct differences in the action mechanisms and effects of the desizing agents. Hydrochloric acid and ammonium persulfate demonstrated rapid sizing material removal, but also caused a noticeable reduction in mechanical properties and air permeability, which is attributed to their oxidative and acidic properties. In contrast, enzymatic desizing using thermostable amylase ensured effective removal of size material while maintaining fabric strength, elongation, and permeability characteristics. These findings support the potential of enzymatic desizing as a more fabric-friendly and sustainable alternative to conventional chemical methods, particularly for plain weave cotton substrates.
