Problems solved by technology

However, conventional lamination methods using glue and / or thermal bonding systems (see DE 4407097 and US 5,951,798) inherently increase the stiffness of the material, whereby the comfort parameters of the upholstered furniture are reduced
In addition, the assembly of upholstered furniture becomes more difficult

Embodiment Construction

[0021] As explained above, bonding a spunbond nonwoven to a nonwoven fill can adversely affect the comfort parameters provided by the fill when used in upholstered furniture. Additionally, it requires additional processing.

[0022] In order to provide a single material for use as an inner lining in upholstered furniture, according to one embodiment, an inner lining comprising a layered material having at least two layers is provided. The first layer is a carded thermally bonded nonwoven fill and the second layer is a carded thermally bonded nonwoven top layer. In use, the batting will face the comfort material (eg PU foam), such as that of an upholstered furniture piece or mattress, and the top layer will face the cover. The carded nonwoven fill is thermally bonded to the carded nonwoven topsheet by means of bicomponent binder fibers (eg core-sheath binder fibers or side-by-side binder fibers) present in the fill and topsheet respectively. As known in the art, bicomponent f...

Abstract

The present invention provides an inner lining for upholstered furniture comprising a layered material in which a carded nonwoven wadding is thermally bonded to a carded nonwoven thin top layer. In the inner liner, a high proportion of the staple fibers in the top layer are fine bicomponent binder fibers. In addition, at least 20% by weight of the staple fibers in the fill are thick staple fibers. In addition, the fill also contains bicomponent binder fibers.

Description

technical field [0001] The present invention relates to an inner liner for upholstered furniture or mattresses, said inner liner comprising carded nonwoven wadding. Furthermore, the invention relates to upholstered furniture or mattresses comprising said inner liner. Background technique [0002] Nonwovens are used in a variety of applications in the art. Nonwovens are fabric-like materials made of long fibers that are bonded together by chemical, mechanical, thermal or solvent treatment. The term is used in the textile manufacturing industry to refer to fabrics, such as felt, which are neither woven nor knitted. Nonwovens are defined by ISO standard 9092 and CEN EN 29092. Recently EDANA and INDA have proposed the following aspect of nonwovens to ISO: "Nonwovens are sheets of fibers, continuous filaments or chopped yarns of any origin, which have been formed by any means into and are bonded together by any means other than weaving or knitting.Wet-laid is a non-woven fabr...
