Upholstered comfort member
An upholstered comfort member, comprising a resilient comfort material and a cover fabric. The resilient comfort material comprises lignocellulosic fibres, which provides resilient properties to the resilient comfort material, and a binder at a concentration of between 1 and 30 wt %. The binder binds the lignocellulosic fibres together. The invention further relates to a method for manufacturing of such an upholstered comfort member.
1. An upholstered comfort member, comprising a resilient comfort material, and a cover fabric, wherein the resilient comfort material comprises lignocellulosic fibres providing resilient properties to the resilient comfort material, and a binder, wherein the binder is a bi-component binder fibre comprising a thermoplastic material, at a concentration of between 1 and 30 wt %, the binder binding the lignocellulosic fibres together, and wherein the lignocellulosic fibres have a length of about 1 to 50 mm.
2. The upholstered comfort member according to claim 1 , wherein the lignocellulosic fibres are wood fibres.
3. The upholstered comfort member according to claim 1 , wherein the binder is present at a concentration from 1 to 20 wt % in the resilient comfort material, and wherein the lignocellulosic fibres are present at a concentration of between 70 and 99 wt %.
4. The upholstered comfort member according to claim 3 , wherein the lignocellulosic fibres are present at a concentration of between 80 and 97 wt %.
5. The upholstered comfort member according to claim 1 , wherein the resilient comfort material has a density of between 10 and 100 kg/m 3 .
6. The upholstered comfort member according to claim 1 , wherein the resilient comfort material comprises a flame retardant agent.
7. The upholstered comfort member according to claim 1 , wherein the resilient comfort material has a thickness T of about 5 to 100 mm.
8. The upholstered comfort member according to claim 1 , wherein upholstered comfort member is an upholstered furniture member, the upholstered furniture member further comprising a base, and the upholstered furniture member being a headboard of a bed, a back seat, an arm rest, or a cushion seat.
9. The upholstered comfort member according to claim 8 , wherein said base part consists of a solid wood board, a plywood board, an Oriented strand board (OSB), a particle board (also known as low density board), an HDF (high density board), or an MDF (medium density board).
10. The upholstered comfort member according to claim 1 , wherein upholstered comfort member is a mattress or a cushion.
11. The upholstered comfort member according to claim 1 , further comprising a liner ( 140 ), the liner being arranged, at least partly, over the cover material ( 130 ), between the cover material ( 130 ) and an outer fabric ( 150 ).
12. The upholstered comfort member according to claim 1 , wherein said upholstered comfort member further comprises a layer of coil or pocket springs arranged adjacent to the resilient comfort material.
13. A method for manufacturing of an upholstered comfort member, wherein the method comprises the steps of:
providing a resilient comfort material according to claim 1 ;
optionally cutting said resilient comfort material into a piece of resilient comfort material having a desired shape and size; and
covering, at least partly, said piece of resilient comfort material using a cover material.
14. The method according to claim 13 , wherein the method further comprises the step of arranging a cut piece of resilient comfort material on a base part before the step of covering said piece of resilient comfort material.
15. The method according to claim 13 , wherein the method further comprises the step of applying a liner onto the cover material.
16. The method according to any one of claim 13 , wherein the method further comprises the step of applying an outer fabric onto the cover material.
17. The method according to claim 13 , wherein a method for manufacturing the resilient comfort material comprises the steps of:
mixing lignocellulosic fibres and bi-component binder fibre, whereby a mixture of lignocellulosic fibres and binder comprising between 1 and 30 wt % of the binder is obtained;
transporting the mixture through a roller into an oven;
subjecting the mixture to heat in the oven such that the binder partly melts and binds the lignocellulosic fibres together; and
extracting the formed resilient comfort material from the oven.
18. The method according to claim 17 , wherein the step of mixing the desired amount of lignocellulosic fibres and the binder is conducted in an aerated drum in a plurality of sequences.
19. The method according to claim 17 , wherein the step of subjecting the mixture to heat further comprises adjusting the height of the mixture soon to be the resilient comfort material with rollers in the oven.
20. The method according to claim 17 , further comprising a step of cutting the formed resilient comfort material into predetermined shapes, lengths and/or sheets.
