Fire or explosion hazards require special motor enclosures. Hazards include combustible gases and vapors such as gasoline dust such as coal, flour, or metals that can explode when suspended in air and fibers such as textile lint. The land of motor enclosure used depends on the type of hazard, the type and size of motor, and the probability of a hazardous condition occurring. Some available enclosures are explosionproof motors, which can withstand an internal explosion force-ventilated motors cooled with air from a safe location and totallv enclosed motors cooled bv air-to-water heat exchangers and pressurized with safe air, instrument air, or inert gas,...

However, motor speed was also the first function in washing machines to be electronically controlled. The standard nowadays are controllable AC- or DC-mo-tors. Depending on the textile type or wash program, such drives can be used to achieve optimal wash speeds, reversing rhythms and activation times. Usually a tachogenerator on the motor is used as a speed sensor. Such a smaller modem motor, connected to a small electronic control unit, is shown on the right hand side of Fig. 3.2. 

Methanol A light, volatile alcohol (CH30H) eligible for motor gasoline blending. It is also used as a feedstock for synthetic textiles, plastics, paints, adhesives, foam, medicines and more. 

There are other minor nonequivalencies of ISO test procedures compared to ASTM standards, but for color difference the ISO Test Procedure No. 105 is unique. Those who use Colour Measurement Committee (CMC) procedures—particularly CMC 2 1 Lightness to Color ratio—claim that it facilitates a uniform description for acceptability decisions that is better than any other system in existence. These equations permit the use of a single number tolerance, DEcmc, in a nearly uniform color space. The CMC formula is a modification to the perceptibility CIELAB formula. It is fully described elsewhere in this book, but it deserves some brief notice here because, after all, it is an ISO procedure. The CMC developed the basic British Standard No. 6923, Calculation of Small Color Differences. Soon afterward, in 1989, the American Association of Textile Chemists and Colorists (AATCC) adopted AATCC Test Method 173, CMC Calculation of Small Color Differences for Acceptability. Ford Motor Company indicated a preference for using CMC 2 1 ratio color difference for plastics weathering data for plastics interior trim materials.

Large amounts of nitrosamines leak into the environment from the pharmaceutical and food industries, plastics industry, textile industry, waste transport (motor vehicles), industrial effluents (dyes, lubricants, mbber), and the production of solvents. Fuel manufacturing plants and oil refineries are also important emitters of nitrosamines, as well as landfills and fossil fuel combustion processes (to produce heat and power). These compounds naturally penetrate the environment through animal droppings. 

Hydrogen peroxide is used in the bleaching of textiles and in the preparation of organic peroxides. Peroxide 85% has been employed in conjunction with hydrazine, methyl alcohol or certain other combustibles as a fuel for rocket motors. When catalytically decomposed it serves as a propellant for torpedoes. 

Applications Magnesium sulfate is utilized in the potassium chemicals industry for the manufacture of potassium sulfate (from potassium chloride), sodium sulfate and potash magnesia (potassium magnesium sulfate). Magnesium sulfate, particularly as kieserite, is used as a fertilizer (ca. 80% of total consumption). It is also used in the textile industry, in the manufacture of building and refractory materials, in the pulp industry and in the production of animal feedstuffs and motor oil additives. 

The great demand for strong regenerated cellulosic fibres in the manufacture of motor car tyres created an outlet where high elasticity was not of such importance as in the manufacture of textile materials. Very great quantities of highly orientated viscose yarns are now manufactured for this end use. 

Polybenzimidazole fibre forms one of the most fire-resistant textiles (mp 760 °C usable to 540 °C) and, although very expeusive, is used for high-tech applicatious, such as protective clothing for fire fighters, astronauts and motor-racing drivers.
