Technical Field

Background

Spandex, a short name for polyurethane fiber, is an elastic fiber which has high elasticity, can be elongated 6 to 7 times, but can be rapidly restored to an initial state with the disappearance of tension, and has a molecular structure of chain-like, soft and extensible polyurethane, and the characteristics of which are enhanced by being connected with a hard segment. Elastic fibers are classified into two categories: one is a polyester chain; one is a polyether chain. The polyester elastic fiber has strong oxidation resistance and oil resistance; the polyether elastic fiber has good mildew resistance and detergent resistance.

Spandex fibers have such high elastic forces because the polymer chains consist of low melting, amorphous, "soft" segments as the matrix and high melting, crystalline, "hard" segments embedded therein. The flexible chain segment has certain cross-linking to form certain netted structure, and has small interaction force and thus great elongation. The bonding force of the molecular chain of the rigid chain segment is larger, and the molecular chain cannot extend without limit, so that high resilience is caused. The cross section of the radon fiber filament is mostly dog-bone-shaped, and the surfaces of the radon fiber filament are smooth or serrated.
