Characteristics of bleach and oxidant resistance in polyester fusible interlining

Polyester fusible interlining is highly favored in the textile industry due to its unique resistance to bleaching agents and oxidants. This feature ensures the stability and durability of polyester adhesive lining fabric in various complex environments.
Bleach resistant properties
Bleaches, especially strong oxidizing bleach containing chlorine or oxygen, have a destructive effect on many fiber materials. Polyester adhesive lining fabric exhibits good resistance to bleaching agents due to its stable chemical structure and chemical resistance. Specifically, the molecular chain structure of polyester fibers is tight and stable, and is not easily destroyed by the active ingredients in bleaching agents. This allows polyester adhesive lining fabric to maintain its original color and physical properties, such as strength and elasticity, during the bleaching process.
Characteristics of antioxidant resistance
Oxidants are also a type of chemical substance with potential destructive effects on fiber materials. They attack the molecular chains of fibers through oxidation reactions, causing to a decrease in fiber performance. However, polyester adhesive lining fabric, with its good resistance to oxidants, can maintain relative stability when in contact with oxidants. The performance of this antioxidant is mainly attributed to the polymer chain structure of polyester fibers and their internal chemical bond stability. The molecular chain of polyester fiber contains a large number of ester bonds, which have high bond energy and are not easily destroyed by oxidants.
