home décor accessory - Cellulose, originally from cotton linters but now chiefly from wood pulp, washed, bleached, and pressed into sheets, is dissolved by chemicals, then forced under pressure through minute holes in a metal cap (spinneret), emerging as filaments that unite to form one continuous strand solidified by passage through a suitable liquid or warm air. The spinning solution may be forced through a larger orifice or slit to produce a monofilament, a ribbon, or a sheet. Filaments are doubled and twisted into smooth, si_lklike yarns or cut into staple lengths and spun. Spun rayon can be treated to simulate wool, linen, or cotton. There are four methods of manufacturi_ng rayon, using different materials and processes. In

the nitrocellulose process developed by Chardonnet, no longer of commercial importance, cellulose is treated with nitric and sulf_uric acids. In the viscose process discovered in 1892, it is treated with carbon disulfide, then dissolved in caustic soda, forced through a spinneret, and hardened in sulf_uric acid. Viscose rayon is the most important type commercially, being used in most kinds of weari_ng apparel, f_urniture fabric, and carpets. For cuprammonium rayon, the cellulose is dissolved in copper oxide and ammonia, forced through holes larger than the intended diameter, then, by a process known as stretch spinning, is elongated and twisted under tension to yield a very fine, strong yarn used for sheer fabrics and hosiery.
