Production and Use Of Polyester Fibres Today and Tomorrow

World production of polyester fibres and filaments in 2002 attained a record level: 20.4 million tons, including 11.8 million tons of complex filaments (+8%) and 8.6 million tons of fibres (+6%). The share of the former has increased at high rates in recent years and is now 58%, which is 16% higher than the share of fibres and twist. New kinds of fibres and filaments based on different polyesters are being manufactured on an industrial scale: liquid crystalline polymers — Vectran HS and Vectran M, poly(ethylene terephthalate) (industrial fibres), poly(butylene terephthalate) (fibres with high dyeability), and poly(trimethylene terephthalate) (fibres and filaments), as well as fibres with low combustibility, antibactericidal, conducting, and other fibres.     

Separation of stearox-6 from aqueous media by the use of hollow-fiber ultrafilters

Conclusions -- The fundamental possibility of effective separation of Stearox-6 from waste water in the manufacture of viscose fiber by the use of hollow-fiber ultrafilters has been demonstrated.Translated from Khimicheskie Volokna, No. 2, pp. 41–43, March–April, 1993.     

Production and use of polypropylene fibres and yarn

World production of PP fibres in 2004 was approximately 6.3 million tons, including 2.1 million tons of film fibres. The total consumption of PP fibres, including spunbond/meltblown, on the European continent increased by 2.5% in 2004, reaching 2.4 million tons. In the near future, expansion of use of PP fibres for production of nonwovens is projected. The world market capacity will increase by 2008 to 3.55 million tons, including up to 1.0 million tons in North American countries. A wide assortment of PP products in the form of films, ribbons, fibrillized materials, staple fibre, complex yarns, spunbond, meltblown, etc., for manufacturing bags, soft containers, agrotextiles, packaging, cables, carpets, hygienic and medical goods, etc., has been developed. __________ Translated from Khimicheskie Volokna, No. 5, pp. 3–7, September–October, 2006.
