The use of microemulsion spray/centrifuge techniques can reduce the discharges of permethrin to as low as 1.7 g of permethrin discharged per ton of wool treated for the microemulsion spray/centrifuge technique, compared to 8.0 g of permethrin discharged per ton of wool treated for the conventional hank treatments in dyebaths [49-51]. 

enar zero-pollution discharge application methods would include the use of low liquor ratios, microemulsions, accurately metering minimum necessary amounts, better process controls, and the like. Research continues on these alternatives and promising developments are underway. 

Type of Goods % Waste Typical Best (upper limit of utilization) 

In developed economies, the textile industry has placed great emphasis on compliance with environmental regulations, which are strictly enforced. The record of the industry in general has been exemplary. Many manufacturers have gone far beyond required levels of environmental protection. Excellent waste treatment systems and fairly sophisticated pollution prevention programs are the norm. Further improvements in these settings will develop along one of two hues of attack. 

Second is expansion of the concepts of pollution prevention to a level transcending unit process boundaries, and even transcending facility or corporate boundaries. This is sometimes very difficult because of business issues but is beginning to see some progress.

The most important properties of refractory fibers are thermal conductivity, resistance to thermal and physical degradation at high temperatures, tensile strength, and elastic modulus. Thermal conductivity is affected by the material s bulk density, its fiber diameter, the amount of unfiberized material in the product, and the mean temperature of the insulation. Products fabricated from fine fibers with few unfiberized additions have the lowest thermal conductivities at high temperatures. A plot of thermal conductivity versus mean temperature for three oxide fibers having equal bulk densities is shown in Figure 2.

Paper- or foil-backed mineral wool product fabricated from low-density slabs in which the slats stand upright with the fibers predominantly perpendicular to the major faces. This type of product is used on circular and elliptical ducting, pipes and vessels to give a compression-resistant insulant. Supplied in roll form. 

In addition to the development of new products with previously unavailable property combinations, the task of making the process more efficient is important, particularly in this day and age. The cost factor energy can still be reduced if, for example, the heat of polymerization can be better utilized. It has been suggested that heat pumps be used for this purpose and the energy recovered be employed for the devolatilization step (38). In the same paper the author also suggests the integration in one factory of the monomer/polymer and end product fabrication, the latter since the polymer is already available in the molten state.

Calendering involves passing unformed or extruded rubber through a set or sets of rolls to form sheets or rolls of rubber product. The thickness of the material is controlled by the space between the rolls. The calender may also produce patterns, double the product thickness by combining sheets, or add a sheet of rubber to a textile material. The temperature of the calender rolls is controlled by water and steam. Products produced by this process include hospital sheeting and sheet stock for other product fabrication. 

When hazardous chemicals are used as raw materials in a process for example, chlorine, a very toxic gas, is an important raw material in the manufacture of plastics, pesticides and herbicides, medical products, fabrics, and many other products. 

In a survey of volatile organic chemicals in 1159 household items including household cleaners and polishes, paint-related products, fabric and leather treatments, cleaners for electronic equipment, oils, greases and lubricants, adhesive-related products, automotive products and miscellaneous products, ethylbenzene was identified in 157 of 658 (24%) of the products tested. The highest mean concentrations and percentage of products in each category in which ethylbenzene was found were as follows 7.2% w/w in 7.5% of automotive products, 2.4% w/w in 47.8% of paint-related... 

Vinyl chloride is consumed in large quantities as a raw material to manufacture pipe, hose, wrapping, and other products fabricated from polyvinylchloride plastic. This highly flammable, volatile, sweet-smelling gas is a known human carcinogen. 

The reactively modified stream is then transformed into pellets, either by underwater or strand pelletizers. The pellets are again dried and shipped to plastic product fabricators, who need such specially modified macromolecular structures to fulfill product property... 

If the compatibilizer is reactive, the rapid and effective melting and mixing will establish the proper conditions for a uniform molten-phase reaction to take place. Thus, by employing TSEs, polymer processors (compounders or product fabricators) can create customized, microstructured polymer systems, which we have coined as designer pellets (22), to best serve the special product property needs of their customers they are no longer solely dependent on polymer resin manufacturers.

Literature continues to be rather extensive on this subject since the 1930s. A summarization is provided in this section. Products fabricated include sheets, films, rods and tubes, and embedment. Acrylic castings usually consist of polymethyl methacrylate (PMMA) or copolymers of this ester as the major component with small amounts of other monomers to modify the properties (Chapter 2). Adding acrylates or higher methacrylates lowers the heat deflection temperature and hardness and improves thermoformability and solvent cementing capability, with some loss in resistance to weathering. Dimethacrylates or other crosslinking monomers increase the resistance to solvents and moisture.
