Embodiment Construction

[0016] The present disclosure overcomes the problems noted in the prior art by providing a mattress having one or more three-dimensional polylactide fiber matrix layers. The polylactide polymer (PLA) that defines the three-dimensional fiber matrix is ​​also known as polylactic acid. PLA is a biodegradable thermoplastic aliphatic polyester derived from renewable sources, as opposed to traditional plastics which are often derived from non-renewable petroleum sources. Several different types of suitable polylactide polymers include racemic PLLA (poly-L-lactic acid), conventional PLLA (poly-L-lactic acid), PDLA (poly-D-lactic acid), PDLLA (poly-DL- lactic acid), PLGA (polylactic-co-glycolic acid), PCL (polycaprolactone) and combinations thereof.

[0017] There is no intention to limit the location of the one or more three-dimensional PLA fiber matrix layers within the mattress. In one or more embodiments, a three-dimensional PLA fiber matrix layer may be disposed on the surface ...

Abstract

A three dimensional polymeric fiber matrix layer (10) for use in a bedding product such as a mattress is disclosed. The three dimensional polymeric fiber matrix layer (10) generally includes a plurality of randomly oriented polylactide (PLA) fibers (12) bonded at coupling points (16) between adjacent PLA fibers (12) and having a free volume per unit area of the layer.

Description

technical field [0001] The present disclosure relates generally to bedding and methods of manufacture, and more particularly, to bedding including a three-dimensional polylactide (PLA) fiber matrix layer. Background technique [0002] A continuous foam mattress associated with all-foam mattress assemblies as well as hybrid foam mattresses (e.g., foam mattresses that include spring coils in addition to one or more foam layers, bladders that include fluid, and various combinations thereof) The problem that exists is user comfort. To address user comfort, mattresses are typically manufactured with multiple layers having different properties, such as density and firmness, etc., to meet the needs of the intended user. A specific area of ​​concern for user comfort is the level of heat build-up experienced by the user over time. Additionally, some mattresses can retain high levels of moisture, further causing user discomfort and potentially poor hygiene. [0003] Unfortunately, ...
