A Comparative Study on The Effects of Different Timing Clorox Bleaching at Different Concentration on Cotton and Polyester Fabric– Tensile Strength

Abstract

Textile fabrics used in industrial applications, workwear and clothing often undergo chemical treatments during the processing and finishing stages. One chemical commonly used in laundry is Clorox bleach (sodium hypochlorite), which is used for bleaching and disinfection. However, such treatments can alter the mechanical properties of fabrics, particularly tensile strength, which is important for durability and performance. The effects of chemical exposure vary depending on the fiber type, concentration, and duration of treatment. Therefore, systematic evaluation of cotton and polyester under different bleaching conditions is necessary to support informed material and fabric selection.
