decorative throw pillows - 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. Rayon produced by these three methods is classified as regenerated, since the final product, like the original material, is cellulose. The fourth type, saponified acetate rayon, originated in England in 1918, is an acetate derivative of cellulose made by steeping cellulose in acetic acid, then treating it with acetic anhydride. Acetate rayon is more resistant to stains and creasing, is plasticized by heat, and requires special dyes, thus allowing two-tone effects with a single dye when acetate is combined with other fibers. An acetate filler is used to make shatterproof glass. Tapestry: hand-woven fabric of plain weave made without shuttle or drawboy, the design of weft threads being threaded into the warp with fingers or a bobbin. The name has been extended to cover a variety of heavy materials, such as imitation tapestries woven on Jacquard looms, tapestry carpets, and upholstery and drapery stuffs. True tapestries include various primitive textiles woven on the rudest of early looms, as well as the famous pictorial hangings of the Middle Ages. The techniques for high-and low-warp work (haute-lisse and basse-lisse) differ; both were used in the 14th cent. In a high-warp loom the threads are stretched vertically in front of the weaver, and the lisses or loops which raise the alternate threads to make the shed are lifted by hand; in low-warp work, the warp threads are horizontal, and the lisses are moved by means of a foot treadle. The strong warp threads of wool or linen may vary from 10 to 30 in an inch (3 to 12 per cm), but are ordinarily fewer than 20 (8 per cm).
