Abstract: Thermally divisible multicomponent fibers having at least a first component including an elastomeric polymer and at least a second component including a non-elastomeric polymer. The multicomponent fibers are useful in the manufacture of nonwoven structures, and in particular nonwoven structures used as synthetic suede and filtration media.

Abstract: A spinneret 20 for producing easily splittable plural-component fibers includes two passages 22 and 26 for respectively delivering two incompatible polymers (A and B) to two sets of inclined capillaries 34-39, 46-51. The two sets of capillaries converge toward each other in a downstream direction and direct molten polymer streams to two respective rows of orifices 40-45, 52-57. The centerlines of the polymer A capillaries lie along axes that, when extended beyond the spinneret, are offset and non-intersecting with axes along which the centerlines of the polymer B capillaries lie, such that the centerlines of the extruded polymer streams are directed along non-intersecting axes. The capillary angles and orifice arrangement cause the extruded polymer streams to extend toward each other in an interleaved fashion, with the polymer streams contacting each other in a generally tangential manner.

Abstract: A carpet having pile which is made up of fibers adhered to each other at points along their lengths with a chemically activated adhesive, as well as a process for treating a carpet, are disclosed. The carpet of the present invention is characterized by improved initial appearance and superior wear resistance when compared to prior art carpet constructions.

Abstract: A yarn formed from a blend of nylon fibers is disclosed. The yarn exhibits improved bulk characteristics and, when utilized as pile yarn in carpet constructions, provides a carpet with improved appearance retention properties with respect to tuft endpoint definition and lack of matting.

Abstract: The present invention is directed to polymeric fibers having a multilobal cross-sectional configuration wherein the lobes are defined by opposing symmetric contours which are curved along their entire lengths. The fibers of the present invention exhibit a desirable sheen with reduced sparkling luster and are useful in yarns suitable for carpet manufacture.

Abstract: Deep-dyeing conjugate filaments are melt-spun by merging molten sub-streams of incompatible polymers to form combined streams, then quenching the combined streams to form the conjugate filaments. The filaments are preferably cold drawn prior to winding, increasing the bulk level in a fabric containing the filaments and increasing the dye stability of the filaments. When the sub-streams are merged outside of the spinneret, the filaments split into the sub-filaments upon exposure to boiling water while under no tension. When the sub-streams merge within the spinneret, the filament is not readily split into sub-filaments, but forms a helically crimped filament.

Abstract: Yarn suitable for use in making cut pile trackless carpet is disclosed. The yarn is composed of two continuous filament singles yarn cabled together with from 3.5 to 5.0 turns per inch (2.54 cm) of twist. Each singles yarn is tangled and contains substantially no twist. The yarn is characterized, in that, each singles yarn comprises, in addition to crimped carpet filaments, filaments having no crimp and a high degree of shrinkage. The yarn develops texture during conventional heatsetting of the yarn without the use of mechanical crimping.

Abstract: A melt-spinning process for producing self-crimping, nylon 66 carpet yarn at spinning speeds of, for example 4000 meters per minute is provided. The process utilizes polymer having a relative viscosity (RV) of at least 50 and containing a sufficient amount of a chain branching agent to prevent broken filaments and to provide yarn having good luster.

Abstract: Improved feed yarns for air-jet texturing are provided by using high molecular weight polyamide polymer spun through non-round capillaries at high spinning speeds to give filament modification ratios greater than 1.5.

Abstract: A self-crimping filament is formed in high-speed spinning by joining hot and cool molten substances of a single polymer substantially at or preferably below the face of the spinneret. This increases the bulk of a yarn containing such filaments.

Abstract: A polyester yarn having filaments with aperiodic varying shrinkage levels along their lengths, the filaments having within-filament and between-filament shrinkage C.V.'s of at least 10%. The yarn may be made by conventional melt spinning within a critical narrow range of spinning speeds wherein yarn shrinkage decreases rapidly with spinning speed. A greige fabric incorporating the yarn as filling is textured by shrinking the unrestrained fabric, then heating the fabric sufficiently to cause the yarn to elongate.

Abstract: A multi-filament splittable conjugate yarn wherein the filaments have the same denier and are splittable into different numbers of sub-filaments.

Abstract: A textured continuous filament yarn combining a luxuriant, soft hand with improved moisture wicking for greater comfort in garments. Some filaments have a denier which varies at least 25% (preferably 300-500%), and other filaments have a spiral cross-section.

Abstract: A yarn for producing fabrics with a wool-like hand, by combining textured filaments with longer filaments preferably of larger average denier. The longer filaments thus protrude in loops from the yarn bundle.

Abstract: An aqueous, coatable, thermally condensable composition is disclosed. The coating is based on dispersions of vinyl acetate polymers in water. Uniquely, the coating can be advantageously used for both nylon and polyester yarns. The coated yarns exhibit performance equivalent to or better than coated yarns based on traditional compositions.
