Lenzing Lyocell Fill filling fiber for bedding

Typical filling materials like down, wool and polyester are compared with Lenzing Lyocell Fill fiber, together with the potential uses of lyocell in 100% and carded fleeces blends for various bedding applications. The requirements for filling fibers generally are described, leading on to the launch of Lenzing Lyocell Fill in 2000. This award-winning fiber technology employs natural, renewable raw materials. The characteristics of a filling fiber are then examined in sub-sections on bulkiness, crimp - the spatial expansion of the filling fiber, elasticity and slip-stick behavior. Performance is tested through the cigarette burn test and washability - methods and results are discussed. Comfort-physiology is reviewed, concentrating on moisture management, with Lenzing Lyocell Fill offering outstanding characteristics which can be further enhanced by polyester blends. Fleeces and fiber-balls are predominantly used in bedding products and these are discussed. Potential applications and the characteristic profile of Lenzing Lyocell Fill are summarised in conclusion.
