• The first ‘micro-denier’ products were introduced by Japanese fiber manufacturing companies during the 1970s. The production of microfibers followed in Europe during the 1980s and since the 1990s by American manufacturers. Toray was the first company in the world to introduce microfibers, followed by Teijin, Hoechst, ICI, DuPont, and others. Recently Toray has introduced an ultra-fine polyester microfiber with a linear density of filament of about 0.05 dtex. This may be called the finest synthetic fiber so far produced commercially. At present, polyester and nylon are generally used for manufacturing microfibers. However, ‘micro-denier’ versions of rayon and acrylic products are on the horizon.

• Three conventional spinning methods, i.e. melt spinning, dry spinning, and wet spinning can be used to manufacture microfibers. However for producing microfibers by these methods, the polymerization process, polymer spinning and drawing conditions have to be selected and executed very carefully. The technology involved in the extrusion of microfibers is more sophisticated and costly than that of conventional deniers as microfibers are delicate products that require great attention in handling during textile mill processing.

Microfiber spinning is now possible by many major fiber producers on their existing equipment, however economical production of high quality microfibers will require significant changes in future machine design and operation. Generally speaking, there are two techniques to produce microfibers:

• direct spinning (conventional POY spinning), and
• bi-component process (segment and island-in-sea type).

Different procedures have been presented and employed to produce microfibers:

• 1.Dissolved type
• 2.Split type
• 3.Direct spun type
• 4.Super-drawing technique
• 5.Sheath-core spinning method
• 6.Flash-spinning method
• 7.Solution flash-spinning
• 8.Emulsion-spinning method
• 9.Jet-spinning method
• 10.Centrifugal-spinning method
• 11.Turbulent forming method
• 12.Conjugate-spinning method.
