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.

Multilobal polymer filaments and articles produced therefrom

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.

Hetero-composite yarn, fabrics thereof and methods of making

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.

Stretchable fibers of polymers, spinnerets useful to form the fibers, and articles produced therefrom

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.

Low or sub-denier nonwoven fibrous structures
