ABSTRACT:
Side-by-side conjugate filaments made from thermoplastic elastomers and spunbond-type polyolefins exhibit an extremely high propensity to self-crimp. At appropriate polymer ratios and processing conditions (with mechanical or aerodynamical drawing) the crimp develops spontaneously after relaxation of the attenuation force. The amount of crimp and the degree of elastic properties depend on the elastomer content and the processing conditions. The resulting crimp is typically in the range of 25-200 crimps per inch. This combination of exceptionally high crimp and an elastomer component imparts stretch and recovery properties. The filaments can be wrapped around a cylindrical supporting structure to create a continuous, seamless elastic band, useful for body-fit articles.
