THPC Treated Flame Retardant Fabric
November 18, 2024
The traditional Proban method uses the flame retardant THPC (Tetrahydroxymethylphosphonium Chloride), which is a white crystalline compound formed by the reaction of phosphine, formaldehyde, and hydrochloric acid at room temperature. The reaction equation is as follows:
THPC can react with cellulose fibers to form crosslinks between cellulose macromolecular chains. The initial finishing process was a simple immersion rolling baking, and the improved process added steps of ammonia fumigation and oxidation. The process flow is: immersion rolling → drying → ammonia fumigation → oxidation → water washing → drying。
THPC Treated Flame Retardant Fabric Advantages: Elevating Flame Retardant Properties
The core advantage of utilizing THPC (Tetrakis Hydroxymethyl Phosphonium Chloride) in fabric treatment lies in its superior flame retardant capabilities. By chemically bonding with the cellulose in the fabric, THPC treatment imparts a durable, flame-resistant quality, significantly reducing the risk of ignition and flame propagation. This proactive approach to fire safety is instrumental in mitigating risks, showcasing how forward-thinking solutions can lead to safer environments.
