New Possibilities of Process Optimisation and Raw Material Selection.

Rieter's FCT-Tester simulates the behavior of a spinning machine to test for cotton stickiness. The UNIclean B10 dedusting and cleaning machine offers improved cleaning efficiency and reduced fiber loss, neps, and fiber damage. The UNIflex fine cleaning machine allows the user to move the feed point closer to the cleaning cylinder at high..

Textile Materials from Chitosan.

Chitosan is ideally suited for a fiber forming technique using the shear precipitation of polymers from solution. The resulting chitosan fibers, which are short and cotton-like, are highly oriented and crystalline. Moreover, they are easily processed into nonwoven structures and papers for medical applications. Chitosan may also be modifi..

Lenzing Lyocell--Potential for Technical Textiles.

Researchers conducted trials to determine the properties of Lenzing's lyocell fibers and potential applications in spunlacing. Lyocell fibers feature good tenacity, elongation, absorption, and fibrillation properties. Processes involved in the manufacture of lyocell fibers are an environmentally friendly alternative to cotton growing, whi..

Properties of Lenzing Viscose and Lenzing Modal Applied to Finishing.

Compared with viscose fibers, Lenzing's Modal fibers offer a higher tenacity, higher wet modulus, lower water retention capacity, lower level of swelling, and greater resistance to alkaline. For homogenous dyeing, manufacturers should not mix viscose and modal fibers. Effective dyes for modal fibers include direct dyes, reactive dyes, sul..

Effectiveness of cleaning cotton fibres on once-through cleaning machines (Russian)

The low cleaning efficiency of the title cleaning machines is shown to be due to the formation on the surface of the toothed cylinder of a web of fibres, the thickness of which does not exceed 3.0 mm and which is commensurate with the gap between the toothed cylinder and the bars. The probability of the fibres being retained by the teeth ..

Worldwide natural fiber survey

Production and consumption figures for cotton and wool between 1955 and 1995 are presented. They show the regional distribution of production, consumption and export volumes for cotton, and production volumes for wool over the period. The supply and demand for wool in the US between 1990 and 1995 are also tabulated.

The future for superabsorbent fibres

The development and use of superabsorbent polymers (SAPs) are reviewed. SAPs are cross-linked acidic polymers (usually polyacrylic acid) in the sodium salt form. They can absorb many times their own weight of aqueous fluids and retain then under an exerted pressure. A more recent development has been SAPs in fibre form. The benefits of th..

Internet information for the textiles industry

This paper introduces the Voluntary Registration Scheme (VRS) for harmless dyestuffs, an initiative of the Hong Kong govenment, in response to the introduction of the German regulation stipulating a ban on the production, import, and sale of consumer goods containing azo colorants produced from certain amines (4th Amendment Regulation to ..

Problems associated with investigating the technological quality of the fibres with regard to the regionalization of new types of common flax (Russian)

The properties of new types of common flax are discussed in relation to two varieties.The impact of dew retting and aqueous retting is also examined. The quality of fibres from different zones of the stem relating to one and the same variety, but subjected to different treatments, can be determined on the basis of the breaking strength an..

Eco-friendly jute textiles-an overview of the problem

The production of eco-friendly textiles is discussed, with particular attention to jute textiles. Eco-friendly textiles are defined as those products which do not transmit any toxic products which may damage the environment. Potentially harmful chemicals used by the jute industry, ways of eliminating them, and equipment used in testing en..
