Blended textiles

Phosphonium Salt—Urea Precondensate. A combination approach for producing flame-retardant cotton-synthetic blends has been developed based on the use of a phosphonium salt—urea precondensate (145). The precondensate is appUed to the blend fabric from aqueous solution. The fabric is dried, cured with ammonia gas, and then oxidized. This forms a flame-resistant polymer on and in the cotton fibers of the component. The synthetic component is then treated with either a cycUc phosphonate ester such as Antiblaze 19/ 19T, or hexabromocyclododecane. The result is a blended textile with good flame resistance. Another patent has appeared in which various modifications of the original process have been claimed (146). Although a few finishers have begun to use this process on blended textiles, it is too early to judge its impact on the industry.

A large amount of fibrous waste is generated each year, consisting of a variety of synthetic and natural polymers. Frequently, different types of polymers and other materials are integrated to form an article, such as blended textiles, carpets, conveyer belts, to name a few. Much of the textile waste collected could be re-used directly, be used as wipes, or be shredded for filling or nonwoven applications. Post-consumer carpet, on the other hand, is a more complex system that often requires extensive processing to convert it into products.
