Problems solved by technology

However, the disadvantage of these materials is that they only have a slight adhesion to each other
Similar to down, feathers, animal hair, etc., the fiber spheres have the disadvantage that they only adhere slightly to each other
[0006] The disadvantage of traditional fiber fleece or nonwovens is that they have less loft than volume-filling materials such as down

Abstract

The invention relates to a nonwoven fabric comprising volume-providing materials, especially fiberballs, down and / or fine feathers, having a surface weight of 50 g / m measured according to DIN EN 29 073 2 In the case of , the nonwoven fabric has a maximum tensile strength in at least one direction of at least 0.3 N / 5 cm, especially 0.3 N / 5 cm to 100 N / 5 cm.

Description

[0001] field of invention [0002] The present invention relates to a nonwoven fabric comprising bulk-providing material, in particular fiberballs, down and / or fine feathers. The invention also relates to the use of a nonwoven fabric as filling material for textile materials such as blankets, clothing and / or upholstered furniture, and a method for producing the nonwoven fabric. Background technique [0003] Various fillers are known for textile applications. For example, fine feathers, down, and animal hairs such as wool have long been used to fill blankets and clothing. The filling material made of down is comfortable to use because it insulates well and is light. However, these materials have the disadvantage that they only adhere slightly to each other. [0004] Fiberballs are an alternative to using these fill materials. Fiber balls contain fibers that are more or less spherically intertwined, and generally have a shape approximately spherical. For example, the fiber ...
