New Trends in Harvesting, Processing and Utilizaing of Hemp.

Hemp plants produce 10 tons of biomass per hm(2). Hemp grows in cool, moderate climates where cotton, sisal, and jute are unable to grow efficiently. Hemp fiber production for apparel, industrial fabrics, and paper is environmentally friendly. Conventional hemp harvesting methods include manual cutting and binding prior to threshing, mech..

Genetical-Breeding Improvement of Flax in Russia

Domestic flax breeding programs have developed 26 of the 35 flax cultivars grown in Russia. Intraspecies hybridization has enlarged the genetic pool for fiber and seed yield selection, lodging resistance, and resistance to fusarium and other flax diseases. The recently developed flax varieties A-29, A-93, alexim, Krom, Lenok, and T-16 hav..

History of Flax, Its Turbulent Life, and Its Future.

The ancient Egyptians used flax fibers in fabrics beginning in approximately 5000 B.C. Flax was first grown in Europe in the 13th century. Successful retting of flax fibers in the river Lys gave rise to a strong flax spinning and weaving industry in Flanders. Dew retting and water retting of flax fibers yields unsatisfactory results for f..

The bicomponent fibre cover as carrier of modifying agents

Raw material basis for the mass production of chemical fibres has not been changed for years. The group of the predominating fibre-forming synthetics i.e. polyester and polyamide was extended within the last decade with polypropylene. Modification of such raw materials allows for production of fibres with more attractive properties. The m..

Micro fibres: The new generation man-made fibres

In the age of constant efforts to improve the quality of textile products, constant efforts have gone into the production of microfibres. Conventional manufacture of man-made fibres has been well established during the early part of the century, however there has still been a constant endeavour to develop fibres resembling natural fibres ..

Properties and application of basalt fibres

In a paper presented to the 81st world Conference of the Textile Institute, basalt fibre properties are described and, at various temperatures, the mechanical properties are investigated. The uses of basalt fibres are discussed and some of the problems they present. The structure and composition of basalt fibres is explained and fibre str..

Staple fibres made from low intrinsic viscosity polytrimethyleneterepthalate

Breakage of filaments during the extrusion of PTT synthetic fibres limits production and product quality, therefore producing PTT synthetic fibres with an intrinsic viscosity range of 0.72-0.82 can help improve fibre production operability and quality without sacrificing fibre properties. The document lists the benefits of reducing the in..

Alkali-soluble polymer and its fiber application

Alkali-soluble polyester is usually manufactured by batchwise polymerization, but the cost of this polymer is high and the operating efficiency of the spinning process is poor because of the instability of the polymer properties. Kanebo Gohsen Ltd, Japan, has developed a direct and continuous polymerization process, in order to overcome t..

Re-positioning acrylic fibers for the new millennium

The technical efforts undertaken by Acordis Acrylic Fibers, UK, to reposition its speciality fibres are described. The performance benefits of the three functional fibres introduced by Acordis in the last 3 years are discussed, with reference to Outlast themoregulatory fibres, Amicor and Amicor Pure, which offer complete protection from t..

Biotechnological methods for manufacturer of cellulosic fibres, films and other products

Biotechnology is one of the dynamically developed domains of world-science and economy. Recently, the biotechnological methods of polymer synthesis, biodegradation and biotransformation have been widely introduced into industry. This trend is justified by numerous benefits resulting from the application of biotechnology, such as mild cond..
