摘要:
A yarn of meltblown thermoplastic fibers is manufactured by meltblowing fibers onto a collector to form a thin web thereon, and continuously withdrawing and twisting the web into a generally circular yarn. In a preferred embodiment the yarn has a reinforcing cord disposed therein to lend strength thereto. The yarn is suited for many applications, including knitted and woven fabrics, and cartridge filters.
