Metallic fibers spinning

Cyanohydrins are used primarily as intermediates in the production of other chemicals. Manufacture of methyl methacrylate, used to make acrylic mol ding resins and clear sheet, eg, Plexiglas acrylic sheet, from acetone cyanohydrin is the most economically important cyanohydrin process (see Methacrylic polymers). Cyanohydrins are also used as solvents in appHcations including fiber-spinning and metals refining. Cyanohydrins and derivatives reportedly act as antiknock agents in fuel oil and motor fuels and serve as electrolytes in electrolytic capacitors. 

Fiber-containing cement was initially developed as a high-strength material that could be used to line a borehole [1789]. Several relatively simple and cheap spin-off applications of fiber cement were identified, such as the use of fiber cement in cement plugs for borehole stabilization and as a lost circulation material. Several companies are already applying or offering fiber cement for these purposes in the field, in both organic fibers and metal fibers [372,1077, 1682-1684]. 

Spinning fibers from a melt is perhaps the most common technique used to make fibers from polymeric and silica-based glasses. Such a technique, however, is not very suitable for metallic fibers because molten metals have very low viscosity. 

In addition to these process, special processes are known, particularly for the manufacture of thin metal fibers the continuous filament process, melt spinning processes and the Taylor process.

Commercial wire drawing processes produce metal wires with round cross sections but they are highly energy and labor intensive. Wire drawing falls outside the scope of this book. Commercial rapid solidification processes yield amorphous metallic ribbons. Inviscid melt spinning yields metal fibers by a chemically assisted jet stabilization process. 

Metallic Fiber n A manufactured fiber composed of metal, plastic-coated metal, metal coated plastic, or a core completely covered by metal (FTC definition). They are available in yam form as well as in staple form for spinning with other fibers. A core yarn with a metal surface is produced by twisting a strip of metal around yarn of natural or manufactured fibers. The most important characteristic of metallic fiber and the chief reason for its use in textiles is glitter. Metallic fibers are used as a decorative accent in fabrics for apparel, bedspreads, towels, draperies, and upholstery. A relatively new application for metallic fibers is in carpet pile, where they are being used in small percentages for control of static electricity. 

Polyolefin fibers are hydrophobic, and the molecular chains within the fiber are tightly packed. Therefore it is extremely difficult to dye polyolefin fibers or to increase their affinity to dyes. Colored inorganic salts or stable organometallic pigments have been added to the polymer melt prior to fiber spinning to color the fibers. Also, nonvolatile acids or bases or materials such as polyethylene oxides or metal salts have been added to the polymer prior to fiber formation to increase the affinity of the fiber for disperse, cationic, acid, or mordant dyes. Polyolefin fibers can be chemically grafted with appropriate monomers after fiber formation to improve their dyeability. 

Metal fibers are mainly used for woven and knitted fabrics. Typical applications of metal fibers are filters (as in polymer melt spinning), antistatic applications (for example, filters, protective clothing), reinforcement structures (tire cord), and also sensors (smart textiles) and architecture (metal fabric fagade).
