Abstract: Composite yarns have a filamentary core provided with at least one elastic performance filament and at least one inelastic control filament. A fibrous sheath, preferably formed from spun staple fibers, surrounds the filamentary core, preferably substantially along the entire length thereof. The at least one elastic performance filament most preferably includes a spandex and/or a lastol filament. The at least one inelastic control filament is most preferably formed of a textured polymer or copolymer of a polyamide, a polyester, a polyolefin and mixtures thereof. Preferably, the fibrous sheath is formed of synthetic and/or natural staple fibers, most preferably staple cotton fibers. The elastic composite fibers find particular utility as a component part of a woven textile fabric, especially as a stretch denim fabric, which exhibits advantageous elastic recovery of at least about 95.0% (ASTM D3107).

Abstract: A method for manufacturing a composite yarn of staple fibers and continuous multifilament yarn. The multifilament yarn is made from non-set, textured, no oil, polyester and first pretensioned before entering a spinning chamber where it is co-spun with the staple fibers which is made from pima cotton. The tension is relaxed after passing through the spinning chamber to allow the filaments of the yarn to expand and form a matrix to which the staple fibers can adhere. The expanded filaments cause the staple fibers to be tightly wound around the core. A composite yarn is also disclosed.

Abstract: A process for the production of a core/mantle yarn, in which a core thread is continuously conducted through a spinning zone in a gap formed between two adjacent and oppositely moving surfaces; staple fibers are fed into the path of the core thread and come into frictional contact with the moving surfaces in said zone to spin the staple fibers about the core thread; the core thread is preferably stretched during the spinning in order to bring about a defined, predetermined elastic stretch of the core thread in the spinning zone; and the core thread has a roughened surface which may be obtained by using a staple fiber yarn or thread obtained by texturizing, weaving, twisting, etc. The invention is especially characterized by an improved adherence of the fibers of the mantle to the core thread by pre-coating the core thread with an adhesive, or preferably by preapplying colloidal silicic acid to the core thread.

Abstract: A narrow woven stretch fabric is formed from bare elastomeric warp threads separated by high shrink warp threads and from a high shrink weft thread. The edge elastomeric warp threads are loosely wrapped with heat set yarn. These edge threads, which are under the same tension as the other elastomeric warp threads, are wrapped between the supply and the loom. The weft thread is interwoven at a low weft per inch and the fabric is heat treated to shrink the non-elastic high shrink threads and corrugate the elastomeric threads without heat setting. The wrapping device and the surface feed rollers for the elastomeric threads are driven by the loom drive at appropriate speeds.
