  Selected synthetic organic fibres (EHC 151, 1993)
The estimated consumption of rayon-based carbon fibres from 1970 to 1976 was 50 to 125 tonnes (Volk, 1979).
Fibres 50 to 100 µm in length with diameters 6 to 8 µm were observed and found to have dimensions similar to those of fibres in the composite material.
Because of the tendency of fibres to align parallel to the direction of airflow, the deposition of fibrous particles in the respiratory tract is largely a function of fibre diameter, with length and aspect ratio being of secondary importance.

 CIRFS | International Rayon and Synthetic Fibres Committee   (Site not responding. Last check: 2007-10-10)
There are two polyolefin polymers used to make synthetic fibres, polypropylene and polyethylene, with polypropylene being by far the most important.
The BISFA definition for polyethylene fibres is "fibre composed of linear macromolecules of unsubstituted saturated aliphatic hydrocarbons" and for polypropylene fibres "fibre composed of linear macromolecules made up of saturated aliphatic carbon units in which one carbon atom in two carries a methyl side group...".
This is due largely to its acceptance as a carpet fibre and the growth in the nonwoven end-uses, especially disposables and geotextiles where polypropylene is now the dominant fibre.

 Photographic support - Patent 4238280
One reason for this is that the fibres originally proposed for this purpose were so dissimilar from conventional cellulosic fibres in their morphology and properties that it was difficult, if not impossible, to make a good quality paper sheet from them.
The newer types of synthetic fibres for use in papermaking (referred to hereafter as synthetic papermaking fibres) and often referred to as synthetic pulp, are generally of polyolefins such as polyethylene and polypropylene and are sold for example under the designations "SWP" by Crown Zellerbach and "Pulpex" by Solvay.
Polyolefinic fibres are thermoplastic, and hence a paper sheet made wholly or in part from polyolefinic synthetic papermaking fibres may be heat treated to provide a sheet with properties which are considerably different from those of conventional paper, and which in some cases are more akin to those of plastics film.

The properties of these fibres, and the ropes made from them, are not significantly different, except nylon 6 has a lower melt point temperature.
Fibre producers' and rope manufacturers' literature may be consulted for other trade names associated with a particular fibre material.
Polyethylene fibres typically are bristle-like, in the range of 0.2 to 0.4 mm dia., and are thus similar to the monofilament form of polypropylene.

Most successful new fibres used for clothes are combinations of both natural and synthetic fibres which manufacturers can mix to give the appropriate washing, dyeing, crease resistance and wearing characteristics required for the garment in question.
Synthetic fibres are mass-produced, giving economies of scale which ordinary farmers cannot achieve.
Restricting the import of cheap synthetics may not comply wit GATT agreements, but home-grown natural fibres should be cheaper to transport to domestic buyers and there is nothing to stop domestic natural fibre industries prompting their products to local users.

 Synthetic fiber - Wikipedia, the free encyclopedia
Synthetic fibers are the result of extensive research by scientists to increase and improve upon the supply of naturally occurring animal and plant fibers that have been used in making cloth and rope.
In general, synthetic fibers, or man-made fibers, are created by forcing, usually through extrusion, fiber forming materials through holes (called spinnerets) into the air, forming a thread.
The original source of this article and much of the synthetic fiber articles (copied with permission) is Whole Earth magazine, No. 90, Summer 1997.

 03 - Synthetic Fibres
Synthetic fibres are obtained from chemical compunds derived from petroleum and are reduced to threads of varying length.
Synthetic fibres began to be commercialised after 1940 and were immediately recognised as products with a vast range of properties, able to satisfy any requirement.
In general, for the production of suits, these fibres are mixed with natural ones rendering the fabrics soft, crease-resistant and hard-wearing.

 Chemistry: Synthetics
Synthetic fibres are "spun and woven into huge consumer and industrial products", from garments such as shirts and scarves, home furnishings such as carpets ad drapes, to industrial parts such as flame-proof linings and drive belts.
Synthetic Colorants: "Synthetic colorants are primarily petroleum-based chemical compounds", unlike natural colorants that are derived from plants, animals and mineral sources.
Those of synthetic origin are mixtures of synthetic compounds, whereas natural flavourings are extracted from plants, animals, spices and herbs.

The fibre is processed mainly in the producing countries themselves and is used for the manufacturing of traditional products such as hessian cloth, food grade bags, carpet backing and other floor covering.
During the past decade, world jute consumption contracted as the market continued to be shaped by two important factors, namely the intensity of competition with, and the displacement by, synthetic fibres, and the extension of commodity bulk-handling facilities.
Increased capacity in the synthetic fibre industry, especially in East Asia, is expected to increase polypropylene's competitiveness vis-à-vis jute fibre, and further erode the demand for the major jute products, such as sacking and carpet backing, thus exerting downward pressure on jute prices.

 Renovo Synthetic Plaster - FAQs
After a lot of research undertaken by our principals in the laboratory, they come to the conclusion that Synthetic Fibre is the best material available for plaster manufacturing along with other chemicals.
- Synthetic Fibres also improve the thixotrophy of the plaster, thereby preventing separation and improving its non-sag properties; hence allowing the thickness of the applied layer to be increased.
Their alkali resistance is good and since the fibre surface is rough, it gives good adhesion and anchorage to the plaster.
