Abstract: The elastic fabric comprising a cross-linked polyolefin fiber, wherein the fabric has retractions both in warp-wise and weft-wise directions of the fabric of 8% or less after treated by dry heat at 65° C. for 30 minutes is disclosed. Also disclosed is a process for producing an elastic fabric, comprising: retracting a fabric comprising a cross-linked polyolefin fiber while dyeing the fabric, and then stretching or relaxing the fabric at a stretch ratio of 15% or less to finish the fabric with heat-setting. The present invention relates to an elastic fabric having an excellent chemical resistance and an excellent dimensional stability in the form of a product, which is suitably used for sporting fabrics such as swimming suits, leotards and the like, inner fabrics for ladies as well as outer fabrics, for example.

Abstract: Durable stretch fabrics are made and processed from one or more inelastic and one or more elastic fibers, for example, a substantially linear, homogeneously branched ethylene polymer. The fabrics can be made by any process, such as, weaving, knitting, etc., and from any combination of crosslinked, heat-resistant olefin elastic and inelastic (“hard”) fibers, for example, cotton and wool. These fabrics exhibit excellent chemical, resistance (for example chlorine or caustic resistance) and durability, that is they retain their shape and feel (“hand”) over repeated exposure to processing conditions, such as stone-washing, dye-stripping, PET-dyeing and the like, and service conditions, such as washing, drying, etc.

Abstract: A reversible, heat-set covered fiber is described, the covered fiber comprising: A. A core comprising an elastic fiber comprising a substantially crosslinked, temperature-stable, olefin polymer, and B. A cover comprising an inelastic fiber. The fiber is head set by a method comprising: (a) Stretching the covered fiber by applying a stretching force to the covered fiber; (b) Heating the stretched covered fiber of (a) to a temperature in excess of the crystalline melting point of the olefin polymer for a period of time sufficient to at least partially melt the olefin polymer; (c) Cooling the stretched and heated covered fiber of (b) to a temperature below the crystalline melting point of the olefin polymer for a period of time sufficient to solidify the polymer; and (d) Removing the stretching force from the covered fiber.
