Synthetic leather-like Composite with smoke and flame resistant properties

Abstract

A synthetic leather-like composite product comprising a polysiloxane top surface having the appearance and surface characteristics of leather, a polysiloxane solid or cellular core, and a textile fabric barrier layer.

Description

FIELD OF THE INVENTION[0001]This invention relates to a synthetic leather-like composite with low smoke and flame resistant properties. More particularly, the product is a synthetic leather-like solid homogeneous composite material with a polysiloxane top surface having a leather-like appearance, backed by a polysiloxane solid or cellular core and a knitted, woven or non-woven textile fabric of aramid fiber, including 3 mesh / 3D knit spacer fabric, knits of Nomex®, Kevlar® graphite or similar heat and flame barrier therebetween. The product is especially useful for aircraft and aerospace or helicopter seating, and for use as seating in sea vessels, automotive and train transportation, in which the suppression or elimination of smoke and no propagation of flame is of particular importance for safety purposes.[0002]The prior art reflects the various means and methods that have been developed over the years for producing protective fabrics in which a textile fabric (e.g., fire fighting ...

Benefits of technology

[0005]This invention relates to a synthetic leather-like composite material with smoke and flame resistant properties that is useful in a variety of products, including aircraft and aerospace seating, and for use as seating in sea vessels, automotive and train transportation. The inventive product is a composite material comprised of a leather-like polysiloxane top surface, a polysiloxane core, and a flame and smoke barrier layer of knitted, woven or non-woven textile fabric of aramid fiber. The product exhibits low smoke properties and low or no ignition propagation. The composite has a top surface, which is chemically bonded to the polysiloxane core(s). The core layerscan be solid or cellular and are chemically bonded to the textile smoke and flame suppressant. The textile portion of the composite may have a spacer laminated to give a soft touch and feel to the product as well as comfort. Some spacers can also be woven with features inserted therein to both heat or cool the seat cushion. The composite material contains no ignition or smoke producing materials, is easy to care for and has a fine leather-like surface. The synthetic silicone composite can be used to replace a flame barrier, glass and the like. A cloth type product for the same purpose can also be used in upholstery, stadium seating, movie theaters and hospitals, where safety is always an issue. The product can be used in many other different applications where safety is an issue, such as hotels, high rise buildings, in upholstery products such as bed boards, mattress covers, elevators, wall coverings, chairs and sofas to name a few.

Problems solved by technology

This product, however, does not have the leather-like appearance and ease of care such as that of the inventive product herein.
