Bright: Term for man-made fibers which have "natural" fiber luster. Semidull fibers have a small amount of dulling agents- predominantly Titanium dioxide.
Dry-Spinning: - Process in which the dissolved substance is spun via a spinneret into a spinning duct heated by a hot airflow, where the solvent is evaporated. The filaments solidify and are then bundled and wound as yarn such as : acetate and acrylic fibers.
Rayon Fiber: A manufactured fibre composed of regenerated cellulose, as well as cellulose in which substituents have replaced by not more than 15% of the hydrogens of the hydroxyl groups. Rayon Fibres include yarns and fibres made by the viscose process, the cuprammonium process and the now obselete nitrocellulose and sapnofied acetate process. Generally in the manufacture of rayon, cellulose derived from wood pulp, cotton linters or other vegetable matter is dissolved into a viscose spinning solution. The solution is extruded into an acid-salt coagulating both and drawn into continuous filaments. Groups of these filaments may be made in the form of yarns or cut into staple.
Doff: A full set of bobbins produced by one machine a roving frame, spinning frame or a man-made filament yarn extrusion machine.
Narrow Fabric: - A textile fabric not exceeding 300 mm. it can vary from 10 mm. - 300 mm. e.g. tapes, ribbons, elastic bands (with stretch yarn and elastomer).
Fibres: - English term - fibers (USA)
Sizing: - Treatment of warp yarns with sizing agents prior to weaving for improving the processing. Now frequently replaced in the case of filament yarns by the cheaper - intermingling process.
