摘要

PCT No. PCT/DK95/00024 Sec. 371 Date Aug. 19, 1996 Sec. 102(e) Date Aug. 19, 1996 PCT Filed Jan. 13, 1995 PCT Pub. No. WO95/19465 PCT Pub. Date Jul. 20, 1995A method for producing cardable, hydrophobic polyolefin-based staple fibers by applying to spun filaments a first spin finish comprising at least one cationic antistatic agent, in particular a quaternary ammonium salt, stretching the filaments, applying to the stretched filaments a second spin finish in the form of a dispersion comprising at least one hydrophobic lubricant selected from a fatty acid amide condensation product and a hydrocarbon wax, the second spin finish optionally further comprising a polydiorganosiloxane in an amount of up to 15% by weight, and crimping, drying and cutting the filaments to obtain staple fibers; as well as textured, cardable, polyolefin-based staple fibers prepared by the method and hydrophobic nonwoven materials produced from such fibers. The fibers are able to be carded at extremely high speeds and are particularly suitable for use in the preparation of thermally bonded hydrophobic nonwoven fabrics in which a dry, water-repellant surface which can function as a liquid barrier is desired, e.g., for disposable diapers, feminine hygienic products and medical products.
