A liner, comprising a layered material in which a carded nonwoven wadding is thermally bonded to a thin carded nonwoven top layer, for upholstered furniture. In the liner, a high proportion of the staple fibers in the top layer are thin bi-component binder fibers. Further, at least 20 wt % of the staple fibers in the wadding is thick staple fibers. Furthermore, also the wadding comprises bi-component binder fibers.
Claims21
An upholstered piece of furniture comprising:
- a furniture frame component;
- a comfort material arranged on the furniture frame component;
- and
- a liner arranged at least partly over the comfort material of the piece of furniture, said liner comprising a layered material with at least two layers, a first layer of a carded nonwoven wadding comprising staple fibers, and a second layer of a carded nonwoven top layer comprising staple fibers, the carded nonwoven wadding being thermally bonded to the carded nonwoven top layer, wherein the carded nonwoven wadding faces the comfort material, and wherein
- said wadding has a thickness of 4 to 140 mm, and a weight of 50 to 2800 g/m2;
- at least 20 wt % of the staple fibers in the wadding have a linear mass density of at least 6 dtex;
- and 5 to 40 wt % of the staple fibers in the wadding are bi-component binder fibers;
- and
- said top layer has a thickness of 0.05 to 4 mm, and a weight of 20 to 120 g/m2;
- at least 90 wt % of the staple fibers in the top layer have a linear mass density of 5 dtex or less;
