Abstract: The present invention relates to stretchable, synthetic, polymeric fibers, tapes and films made from at least two types of thermoplastic elastomeric polymers. More specifically, this invention relates to stretchable synthetic, polymeric fibers, tapes comprising a segmented thermoplastic elastomeric polymer, and an olefinic, thermoplastic elastomeric polymer. This invention also relates to articles formed from such fibers, including yarns, garments, and other textile or related structures comprising such a composite filament or a film.

Abstract: Highly crimped, fully drawn bicomponent fibers, prepared by melt-spinning, followed by gas-flow quenching, heat treatment and high speed windup, are provided, as are fine-decitex and highly uniform polyester bicomponent fibers.

Abstract: The present invention relates to methods for making polyamide filaments, such as nylon 6,6, having high tensile strength. The invention also relates to yarns and other articles formed from such filaments. The invention is particularly useful for providing a filament yarn with tenacity equal or superior to the prior art at high spinning process speeds while retaining the ability to draw the yarn. The invention further relates to providing a filament yarn extruded from a delustered or pigmented polyamide 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: A method of making polymeric, e.g., polyester, filaments having low denier spread by use of a polymer of high viscosity is described. The filaments are useful to make yarns and other articles.

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: Thermoplastics may be melt spun at high production rates, and without physical property degradation, by spinning a blend of the thermoplastic and a minor amount of a specified liquid crystalline polymer.

Abstract: A melt spinning apparatus for spinning continuous polymeric filaments including a first stage gas inlet chamber adapted to be located below a spinneret and optionally a second stage gas inlet chamber located below the first stage gas inlet chamber. The gas inlet chambers supply gas to the filaments to control the temperature of the filaments. The melt spinning apparatus also includes a tube located below the second stage gas inlet chamber for surrounding the filaments as they cool. The tube may include an interior wall having a converging section, optionally followed by a diverging section.

Abstract: Yarns of melt-spun polymeric filaments are rapidly quenched, whereby the filaments are cooled by quenching gas that is accelerated along the threadline by being passed through a tube of reduced dimensions with the filaments before they emerge. In particular, a yarn is produced which has an elongation to break of about 100% or more. The yarn is comprised of filaments numbering from 25 to 150. The filaments are less than 4 denier per filament and makeup yarns having low denier spread.
