DITF: carbon fibers from beech wood

Beech wood is a sustainable and CO2-neutral raw material. Although available in abundance, it has not been utilized to date. On August 9, 2019, the Ministry for Rural Areas and Consumer Protection of the state of Baden-Württemberg, Stuttgart/Germany reached a research collaboration agreement with the German Institutes for Textile and Fiber Research Denkendorf (DITF) in Denkendorf/Germany. In the planned research center for hardwoods, DITF scientists will investigate carbon fibers from beech wood.
The research center will connect 8 research teams from different institutes and serve as a touch point for industry. The DITF is tasked to develop economic and environmentally friendly production processes for cellulose and lignin fibers made from beech wood for technical applications. In the laboratory, carbon fibers have already been successfully produced from beech pulp and beech lignin using a new process that saves energy costs.
This raw material is based on crude oil and the production of carbon fiber from this precursor produces toxic by-products that have to be cleaned at great expense. Advantages in reducing process costs and improving the ecology of carbon fiber production based on cellulose and lignin fibers can be seen.

Teijin Frontier: easy-care silk-like polyester fabric

The fiber-product converting company Teijin Frontier Co., Ltd., Tokyo/Japan, has developed a polyester fabric that looks and feels like fine silk. The company envisions various applications for its silk-like material, such as blouses and outers from thin to medium thicknesses.
While high-function materials made with synthetic fibers are recently established as a fashion trend in the market, demand has also been growing for natural-texture materials made with natural fibers. Materials in which delicate fiber fluff is expressed, or fibrillated, on the surface of the fabric for smooth textures, similar to silk or cupro, are becoming popular, but these materials have problems with color fastness in wet condition, yarn strength, color migration, fading due to fluff release and shape loss by washing.
Teijin Frontier has developed interesting processing technologies to produce a new stable, easy-care polyester fabric that boasts the soft texture and fine appearance of silk produced by wild silkworms. This new material’s specially fabricated surface is soft and glossy, holds bright coloring, and resists color migration, shrinkage and shape loss by using polyester fibers with very good color fastness and fiber strength.

Lenzing: expansion of pulp production at the Lenzing site

The producer of cellulosic fibers, Lenzing AG, Lenzing/Austria, has concluded its expansion and modernization drive at the pulp plant at the Lenzing site. The company invested €60 million for this purpose, increasing production capacities for dissolving pulp extracted from beech wood from 300,000 to 320,000 tons/year.
The successful expansion brings the company closer to achieving the strategic objective of increasing self-supply of pulp to a level of 75%, thus making it even more resistant to price fluctuations in sourcing pulp. At present, Lenzing’s own pulp plants in Lenzing and Paskov/Czech Republic cover 60% of the group’s pulp requirements. The Lenzing site primarily makes use of beech wood which is not suitable for producing furniture, whereas it mainly relies on spruce wood in the Czech Republic. The remaining dissolving wood pulp is sourced from a variety of hardwoods and softwoods from international partners.
