    Abstract: Method for making caprolactam from 6-aminocapronitrile that contains greater than 500 ppm tetrahydroazepine and its derivatives (THA) in which ammonia and water are removed from crude caprolactam in a single separation step and then THA is removed from the resulting caprolactam melt.

    Abstract: A continuous method for producing composite elastic yarns at speeds up to 700 m/min by (a) stretching (drafting) an elastomeric yarn (e.g., spandex) by 2.0x (100%) to 10.5x (950%) while heating (max. heating temperature 220°C) in a single or double stage draft, (b) air-jet entangling with a relatively inelastic yarn component to create a composite elastic yarn, and then (c) in-line heat-treating (max. heating temperature 240°C) the composite elastic yarn. The initial draft stage(s) may also be carried out at ambient temperature. The resulting composite elastic yarn has improved stitch clarity, particularly suited for hosiery, and its properties can be tailored to provide fabric properties for knit and woven fabrics hitherto not possible with standard spandex yarns.

    Abstract: The invention provides stretch fabrics and articles from the fabrics comprising at least a region consisting of a single thickness of the fabric. The fabric comprises synthetic bicomponent polymer filaments, wherein the fabric has been calendered on at least one surface thereof to obtain a chintzed appearance. The fabric has an air permeability of less than 6 cubic centimeters per second per square centimeter, (cm3/cm2/sec), at 10 millimeters water gauge pressure.
