Bleached White

Bleached white fabric has undergone a chemical bleaching process to remove the natural yellowish or grayish tint present in raw fibers, resulting in a clean, bright white appearance. This process transforms greige fabric into a pristine base suitable for white products or light-colored dyeing.

The bleaching process for polyester fabrics typically uses hydrogen peroxide or sodium hypochlorite under controlled temperature and pH conditions. The treatment removes natural impurities and any residual color from the fibers. Many bleached fabrics also receive optical brightening agents, which absorb ultraviolet light and re-emit it as visible blue light, creating an enhanced perception of whiteness.

Whiteness is measured using the CIE whiteness index, with commercial bleached fabrics typically achieving values between 120 and 140. Higher values indicate a brighter, more brilliant white appearance. The specific whiteness level can be adjusted based on customer requirements, with some applications demanding exceptional brightness while others prefer a softer, more natural white.

Bleached white fabric is produced in weights ranging from 60 to 150 GSM and widths up to 315cm. The fabric serves multiple purposes in the textile industry. It provides the ideal base for dyeing light or pastel colors, where any underlying tint would affect the final shade. White bedding products, including sheets and pillowcases, are typically made from bleached fabric. The medical and hospitality sectors rely heavily on bleached white textiles for their clean, hygienic appearance. Additionally, bleached fabric serves as an excellent base for printing, where a neutral white background ensures accurate color reproduction.
