Celanese Corporation is a Fortune 500 global technology and specialty materials company with its headquarters in Dallas, Texas, United States.
Determination of the variation in weight per unit length and thickness of yarns or fibers aggregates such as roving, sliver, or top.
Industry:Textiles
An aftertreatment to remove sulfur from newly spun viscose rayon by passing the yarn through a sodium sulfide solution.
Industry:Textiles
Acid dyes that are treated with coordinating metals such as chromium. This type of dye has much better wetfastness than regular acid dye. Premetallized dyes are used on nylon, silk, and wool.
Industry:Textiles
A zero-twist bundle of continuous filaments that has been stretched to achieve molecular orientation. (Tows for staple and spun yarn application are usually crimped.)
Industry:Textiles
A yarn-dyeing process in which each strand is dyed with more that one color at irregular intervals. Space dyeing produces an effect of unorganized design in subsequent fabric form. The two primary methods are knit-de-knit and warp printing.
Industry:Textiles
A weight-per-unit-length measure of any linear material. Officially, it is the number of unit weights of 0.05 grams per 450-meter length. This is numerically equal to the weight in grams of 9,000 meters of the material. Denier is a direct numbering system in which the lower numbers represent the finer sizes and the higher numbers the coarser sizes. In the U.S., the denier system is used for numbering filament yarns (except glass), manufactured fiber staple (but not spun yarns), and tow. In most countries outside the U.S., the denier system has been replaced by the tex system. The following denier terms are in use
Industry:Textiles
A viscous, sweet, colorless liquid, (CH<sub>2</sub>OHCH<sub>2</sub>OH). Principal uses are as an intermediate in the manufacture of polyester fibers and as automobile antifreeze.
Industry:Textiles
A type of water-soluble anionic dye having affinity for cellulose fibers. In the presence of alkali, they react with hydroxyl groups in the cellulose and thus are liked with the fiber. Fiber-reactive dyes are relatively new dyes and are used extensively on cellulosics when bright shades are desired.
Industry:Textiles
A type of azo compound formed on the fiber by first treating the fiber with a phenolic compound. The fiber is then immersed in a second solution containing a diazonuim salt that reacts with the phenilic compound to produce a colored azo compound. Since the phenolic compound is dissolved in caustic solution, these dyes are mainly used for cellulose fiber, although other fibers can be dyed by modifying the process.
