Addition of additives polymeric materials

A process for introducing additives into a polymer melt comprising dispersing at least one additive in an at least partially volatile liquid vehicle with a dispersion and stabilizer for the dispersion; feeding the resulting dispersion to a vented extruder which is extruding a polymer; and removing the fed volatiles through the extruder ve..

Method and composition for incorporating radiation-absorbing agents into polymers

A method of incorporating dyes into polymeric materials. The method involved contacting a functionalized dye with a high molecular weight cross linkable polymer precursor, dispensing the solution into a mold and applying radiation, thereby forming a molded article having dye covalently bonded to the polymer backbone. A preferred product i..

Oxidative Degradation of Polymers: An Introduction.

Exposure to atmospheric oxygen, particularly at high temperatures, and light degrade polymers via oxidation, defined as the reaction of the polymer with oxygen at temperatures at which thermal degradation is negligible. Combustion is the reaction between oxygen and volatile products of thermal decomposition. Model compound studies indicat..

Biotechnology for textile industry

Biotechnologies are a modern stormy developing branch that pervades many industrial areas. They open space for utilisation of non-traditional sources of raw materials and adoption of wholly new technological processes, including wasteless production and waste valorisation. Today all these trends are very desired also for development and m..

Photodegration of Lyocell fibers through exposure to simulated sunlight

This research investigates changes occurring in lyocell fibers resulting from exposure to simulated sunlight. FTIR microspectroscopy is used in combination with measurements of tensile properties, fluidity, moisture regain, yellowness, weight loss, and birefringence. X-ray diffraction and SEM are used to determine crystallinity and fiber ..

Aspects concerning the processing of Alceru stale fibres (German) (Aspekte zur Verarbeitung von Alceru-stapelfasern)

The characteristics of Alceru staple fibres put them in the same quality bracket as lyocell fibres. From among the many parameters which affect the processing behaviour and quality of the end product, the fibre finish was selected for special study in relation to the extent to which the fibre manufacturer can exert an influence here. The ..

European fiber producers show new trends at Paris expofil

The 44th Expofil yarn fair took place in Paris in December 2000, attracting slightly fewer visitors than the same season in 1999. The show emphasized sheers and lightweight fabrics for spring/summer 2002. More than 30 companies demonstrated new and old fibers for the European yarn sector. These included Dryarn, a new polypropylene microfi..

Creating a microfiber for comfort (French) (Creer une microfibre pour son confort)

The aims and philosophy behind the development of Filifine fibres by Tergal Fibres are presented. The fibre has a diameter of 9 um and can be blended easily with both natural and synthetic fibres. Particular attention was paid to developing a fibre which was soft, comfortable to wear, and which would dry quickly. Other important propertie..
