Dorlastan Black avoids need to overdye spandex fibers
Dormagen based embodiment of textile elasticity firm Dorlastan Fibers GmbH has added Dorlastan Black to its product range. This new spandex fiber prevents unacceptable grin-through in dark fabrics, regardless of which other fibers they contain.
Separate overdyeing of the spandex fiber is therefore unnecessary where the dyes only stain the non-elastic fibers. Dorlastan Black also prevents grin-through in elastic combination yarns containing dark dope-dyed hard fibers such as polyester, polyamide or acrylics.
This new polyester-based fiber type is available in 40 and 70 denier. It has excellent fastness to light, UV and NOx. Since it also has outstanding stability to PER and chlorine, it is suitable for use in swimwear and can be dry cleaned without problem. The black shade of the fiber is stable to cleaning with both solvents and aqueous liquors.
The company is exhibiting its new fiber, together with its extensive range of other products for the textile industry, at Interfilière in Lyon, France, from September 2-5, 2005. Trends for 2007 will also be presented.
The Dorlastan product range comprises filament yarns made of segmented polyester/polyurea urethane. Small amounts of these yarns are sufficient to give fabrics optimal stretch properties (elongation and elastic recovery power), dimensional stability and wear comfort. They are also extremely durable. This combination of outstanding properties makes Dorlastan spandex yarns an idealcomponent for modern yarns, fabrics and apparel.
