Abstract
A three dimensional polymeric fiber matrix layer for use in a bedding product such as a mattress is disclosed. The three dimensional polymeric fiber matrix layer generally includes a plurality of randomly oriented polylactide (PLA) fibers bonded at coupling points between adjacent PLA fibers and having a free volume per unit area of the layer.
Claims19
A three dimensional polymeric fiber matrix layer for a mattress construction, comprising:
- a plurality of randomly oriented polylactide (PLA) fibers bonded at coupling points between adjacent PLA fibers and having a free volume per unit area of the layer, wherein the three dimensional polymeric fiber matrix layer is preconditioned, wherein a portion of the coupling points are detached and a portion of the randomly oriented polymer fibers become fragments so as to change a mechanical property of the pre-conditioned three dimensionally PLA fiber matrix layer relative to the three dimensionally PLA fiber matrix layer without pre-conditioning.
(canceled)
A mattress comprising:
- at least one three dimensionally PLA fiber matrix layer comprising randomly oriented PLA fibers bonded at coupling points between adjacent fibers and having a free volume per unit area of the layer, wherein the at least one three dimensionally PLA fiber matrix layer is pre-conditioned such that a portion of the coupling points are detached and a portion of the randomly oriented polymer fibers become fragments so as to change a mechanical property of the pre-conditioned three dimensionally PLA fiber matrix layer relative to the three dimensionally polymeric fiber matrix layer without pre- conditioning.
