行业现状

In the textile industry, hydrogen peroxide is mainly used for fabric bleaching, color development during vat dyeing, and fabric desizing, such as bleaching high-end pure cotton fabrics, linen free fabrics, knitwear and towels, bed sheets, fur and handicrafts. Replacing chlorine bleaching cotton textiles with hydrogen peroxide has certain advantages in the textile industry due to its minimal loss of fiber strength, resistance to yellowing, and full hand feel. It can also eliminate the pollution of organic chlorine in wastewater discharge caused by chlorine bleaching, simplifying the wastewater treatment of cotton mills.

Cotton fabric bleaching

Hydrogen peroxide is a key reagent for bleaching cotton fabrics. Often prepared as alkaline and stabilizer solutions, adjust the concentration to 2% -8% according to the characteristics of the fabric. High temperature boiling and bleaching, or room temperature cold rolling and stacking, utilize their strong oxidizing properties to decompose pigment impurities, wash the fabric white, help improve the appearance and quality of cotton fabrics, and have a wide range of applications.

Silk bleaching

Hydrogen peroxide plays a crucial role in silk bleaching. Formulated into a specific concentration solution, with a pH value precisely controlled at around 8-9, and slowly floated at a low temperature of 40 ℃ -60 ℃ to prevent protein damage. It oxidizes colored substances, removes yellowing, and makes silk shiny and white in color, while also maintaining strength and ensuring excellent appearance for subsequent processing and silk products.

Wool bleaching

Hydrogen peroxide is indispensable in wool bleaching. Generally formulated as a mild solution containing stabilizers and buffering agents, with a concentration of about 3% -6% and a temperature of 50 ℃ -70 ℃. By utilizing its oxidizing properties, it removes natural pigments from wool, resulting in a lighter and more uniform color.

Other fabric bleaching

For acetate fibers, low concentration hydrogen peroxide is used for low-temperature gentle treatment to prevent damage, remove impurities, and whiten; Flax products are treated with appropriate additives, 3% -5% hydrogen peroxide, bleaching at 60 ℃ -80 ℃, color removal and quality improvement, all of which can rejuvenate the fabric and meet diverse processing needs.
