Use of a lyocell-type staple fibre as a padding fibre

Abstract

The present invention relates to the use of a cellulosic staple fibre of the Lyocell type having a value of the ratio between titre (in dtex) and cutting length (in mm) of 0.10 or more as a filling fibre for blankets, cushions, pillows, mattresses or fleeces for upholstered furniture.

1 . The use of a cellulosic staple fibre of the Lyocell type with a value of the ratio between titre (in dtex) and cutting length (in mm) of 0.10 or more as a filling fibre for blankets, cushions, pillows, mattresses or fleeces for upholstered furniture.  
   
   
       2 . The use according to  claim 1 , wherein the value is 0.5 to 5.  
   
   
       3 . The use according to  claim 1 , wherein the titre of the fibre is 1.3 to 3.3 dtex, preferably to 1.3 to 1.7 dtex.  
   
   
       4 . The use according to  claim 1 , wherein the fibre has a titre of 6.7 dtex and a cutting length of 6 mm.  
   
   
       5 . The use according to  claim 1 , wherein the fibre of the Lyocell type is used in a mixture with at least one fibre of a different fibre type and/or with downs and feathers.  
   
   
       6 . The use according to  claim 5 , wherein the different fibre is selected from the group of synthetic fibres, preferably from the group consisting of polyester fibres, polyamide fibres, polypropylene fibres and polylactate fibres.  
   
   
       7 . The use according to  claim 5 , wherein content of the staple fibre of the Lyocell type is 30 to 50% by weight.  
   
   
       8 . A blanket, a cushion, a pillow, a mattress or a fleece for upholstered furniture, containing a staple fibre such as defined in  claim 1  and/or a mixture such as defined in any of  claims 5  to  7  as a filling fibre.
