Definitions

• the invention relates to a mixed fiber fleece made of polyester fibers and cellulose fibers.
• nonwoven is a textile Understand fabrics made of fibers, its cohesion regularly due to the fibers' own liability.
• Mixed fiber fleece therefore refers to one of two or more fibers composite textile fabric of the above configuration.
• a mixed fiber fleece of the design described at the beginning is known from DE 44 45 085 C2.
• Ramie fibers are characterized by a relatively good absorbency and special resistance to rotting but are sensitive to what their buckling and bending strength and consequently the relaxation behavior after deformation.
• a mixed fiber fleece made of polyester fibers and ramie fibers before, mostly using 60% by weight polyester is still used when used as a filler for pillows, duvets, mattress pads, sleeping bags, Clothing, etc. required elasticity available to be able to ask.
• the stand requires a certain minimum proportion of technology Polyester fibers so that with the use of ramie fibers necessarily related restrictions regarding the elasticity of the mixed fiber fleece do not constrict.
• the invention is based on the technical problem Mixed fiber fleece of the configuration described above to further develop this through flexibility, good Relaxation ability and at the same time high moisture absorption capacity distinguished.
• the invention proposes Generic mixed fiber fleece made of polyester fibers and Cellulose fibers before that the cellulose fibers viscose fibers are.
• the mixed fiber fleece allows an extraordinary large variation in the proportion of polyester, the values between Can take 20 wt .-% and 80 wt .-%, because the Viscose fibers - in contrast to ramie fibers - extremely are flexible and a perfect relaxation ability have so that the polyester content compared to the Teaching according to DE 44 45 085 C2 can be significantly reduced. Polyester contents up to approx. 50 are particularly recommended % By weight.
• viscose fibers are generally used a fineness (titer) of 1 to 30 dtex, preferably 3 up to 20 dtex.
• viscose fibers are cellulose fibers, which are manufactured using the so-called viscose process have been. At its core, this provides that the one of the Wood pulp initially delivered in (Soda) lye is dissolved and then the ripened Sodium cellulose is reacted with carbon disulphide. At this sulfidation produces an orange / yellow viscous mass, which is called viscose. This viscose becomes Production of a so-called spinning solution with approx. 80% by weight Water content added and pressed through spinnerets, so that the viscose (spinning) fibers on the nozzle outlet side To be available.
• such viscose fibers are relatively large Cavity volumes that a in bending stresses easy absorption of the fiber substance displaced in the bow guarantee. At the same time, this explains the good one Water absorption capacity or the large water retention capacity. In this context you have beyond that found that such viscose fibers contain micro voids, which is not just for quick moisture absorption worry, but also the high flexural strength of the Explain viscose fibers.
• the viscose fibers are particularly large capable of absorbing the moisture that a human being delivers. This works with perfect workability and besides, good suitability of such viscose fibers, taking into account their special Flexural strength. It is also viscose fiber for extremely resistant man-made fibers from natural Polymers so that problems such as rotting, matting, etc. does not matter.
• polyester fibers now ensure that the moisture either directly or excess moisture absorbed by the viscose fibers and later to the Atmosphere is transported away. This works easily in the required scope because the viscose fibers Store the absorbed moisture sufficiently and quickly can, until their complete removal via the Polyester fibers is done.
• a user lies on a lower bed, for example with a filling of the mixed fiber fleece according to the invention quasi dry and feels good because he not perspired.
• the moisture absorption and their transportation to the atmosphere in such a balanced state that man's while sleeping Moisture released while maintaining the desired heat as dry as possible, absorbed, possibly stored and finally released into the atmosphere.
• the relaxation capacity of the lower bed and of course also the other with the mixed fiber fleece according to the invention filled items is excellent, so that Clumps, dents, etc. are not observed.
• the production of the mixed fiber fleece according to the invention can be done so that the viscose fibers together with the Polyester fibers crimped or mixed after homogeneous mixing be carded to a particularly bulky fiber composite fleece to obtain.
• the homogeneously mixed fibers crossed, stacked and additionally partially erected.
• This fleece composite the intermediate transport, Filing and quilting machines fed.
• the result is a particularly suitable filling material for Pillows, duvets, bed inlays, quilts, mattresses, Mattress pads, upholstery, clothing or the like created, which ensures dry heat for its user.
