Abstract
This invention relates to an improved multifilament bundle which is made of thermoplastic polymer and usable without twisting and represents a linen-like touch. The multifilament bundle comprises a plurality of monofilaments of the same kind of thermoplastic polymer, said monofilaments being bonded thermally and partially together with neighboring at separated places thereof, each of said bonded places extending short distance along and in the longitudinal direction of monofilament, so as to make the constituent monofilaments coherent with each other into a non-torqued, non-bulky continuous yarn. This yarn can be fabricated, without sizing, into a textile fabric. This yarn can be used in various fields requiring untwisted yarns including sewing machine yarn. This yarn can be manufactured by passing a multifilament as spun at underfeed condition through a passage zone where heated fluid flows are brought into collision with each other. The fluid may preferably steam, while the material polymer may preferably 6- or 66 nylon.
