Abstract: This invention provides polymer filaments having a multilobal cross-section. The cross-section can have a filament factor of about 2.0 or greater and a tip ratio of greater than about 0.2. The filaments may be used as-spun as a spin-oriented feed yarn or as a direct use yarn. The multifilament yarns made from these filaments are useful to make articles with subdued luster and low glitter.

Abstract: A hetero-composite yarn useful in making garments comprises a combined biconstituent yarn and a companion yarn, wherein the biconstituent yarn comprises an axial core comprising a thermoplastic elastomeric polymer, and a plurality of wings attached to the core and comprising a thermoplastic, non-elastomeric polymer.

Abstract: This invention relates to a new nonwoven material which has very high Frazier permeability while having substantial hydrostatic head liquid barrier properties. The material is comprised of fibers which are approximately one denier and finer fibers which have sufficient strength properties so as not to need a support scrim. The fabric is quite comfortable because of its breathability, quite soft because of its construction, and protective from liquids from rain to hazardous chemicals.

Abstract: This invention relates to a nonwoven sheet material with high air permeability and substantial hydrostatic head liquid barrier properties. The sheet material is comprised of at least 90%, by weight, melt spun substantially continuous filament polymer fibers having an average cross sectional area of less than about 90 square microns. The sheet material has a basis weight of less than 125 g/m2 and a grab tensile strength of at least 0.7 N/(g/m2). The invention is also directed to a process for melt spinning polymer fibers that can be used to make the nonwoven sheet material of the invention.

Abstract: A stretchable synthetic polymer fiber comprising an axial core formed from an elastomeric polymer, and two or more wings attached to the core and formed from a non-elastomeric polymer, wherein preferably at least one of the wings is mechanically locked with the axial core. The fibers can be used to form garments, such as hosiery. A spinneret pack for producing such fibers is also provided.

Abstract: A stretchable synthetic polymer fiber comprises an axial core formed from an elastomeric polymer, and two or more wings formed from a non-elastomeric polymer attached to the core. The fiber has a substantially radially symmetric cross-section. Such fibers can be used to form garments, such as hosiery.
