Abstract
The laminate is formed of a sheet of a woven textile material derived from multifilamentary aramid, polyimide, polyamide, polybenzimidazole or cellulose fire retardant yarns and a sheet of non-woven textile material. The adhesive used to produce the laminate should prevent slippage of the two materials relative to one another and fraying of the woven textile material while enabling the laminate to be air permeable, and having a minimum ten (10) cubic feet per minute (CFM) when tested in accordance with test method ASTM D737. This product is cheaper to manufacture and is more comfortable than the known quilted and coated material.
Description
"LINER FOR FIREFIGHTER GARMENT MADE OF A LAMINATE
OF A WOVEN FABRIC AND A NON-WOVEN MATERIAL"
This invention relates to a liner for a fire-resistant garment, such as a firefighter protective garment. More particularly, the present invention is concerned with a thermal protective liner system composed of a textile material which is a woven or knitted ' Als~A-~ fabric laminated to an insulating medium and which provides a minimum of air ' ~ / of ten (10) cubic feet per minute (CFM), when tested in ~cculd~ce with ASTM D737.
Firefighter protective garments usually consist of three or more discrete layers of fire-resistant materials. The various layers _re normally:
I) the outer shell which provides protection against puncture, cuts, flame and heat;

This invention relates to a liner for a fire-resistant garment, such as a firefighter protective garment. More particularly, the present invention is concerned with a thermal protective liner system composed of a textile material which is a woven or knitted ' Als~A-~ fabric laminated to an insulating medium and which provides a minimum of air ' ~ / of ten (10) cubic feet per minute (CFM), when tested in ~cculd~ce with ASTM D737.
Firefighter protective garments usually consist of three or more discrete layers of fire-resistant materials. The various layers _re normally:
I) the outer shell which provides protection against puncture, cuts, flame and heat;
2) the moisture barrier substrate and moisture barrier polymer which, although fire-resistant, have as their principal purpose protection against liquid penetration (in certain cases they are permeable to perspiration vapor to increase wearer comfort);
3) the thermal barrier insulation whose principal function is to provide protection against heat transfer; and
4) the inner lining or face cloth (which is normally quilted to the thermal barrier in~ n) which protects the thermal barrier from wear from the inside of the garment, and provides a last layer of heat and flame protection.
It will be seen that the inner liner of a firefighter protective garment therefore consists of an inner lining and a thermal barrier material.
To provide a liner which includes a fire-resistant ~ nA-~
fabric, the latter is normally quilted to thermal barrier insulation. ~
order to prevent slipping and fraying of the m7lltifil inner lining, it is customaTy to apply an anti-slippage coating which is well known to those skilled in the art, such as micro coating or kiss coating., to the inner lining. However, in doing so, the liner becomes less permeable to air which is of course undesirable. Indeed, the material should be ~,. ' '- to air to provide comfort to the user and to enable the evaporation of perspiration.
In an effort to provide a liner wherein the inner lining increases wearer comfort, reduces metabolic energy ~ L, and decreases metabolic heat build-up, applicant has designed am improved inner lining which reduces restriction to ll.v v. by the wearer and permits easier and quicker donning and doffing of the garment. A lining of this type is described in U.S. Serial No. 214,571 filed March 18, 1994 and in U.S.
Patent No. 5,323,815 issued Jume 28, 1994. This inner lining is based on aramid, polyimide, polyamide or pol~,l,, ~. l yarns, or yarns made of cellulose fire retardant material. Commercially, this inner lining is available under the commercial ~r~ of Ultraflex TM
It will therefore be seen that providing an ilmer lining with an anti-slippage coating and quilting it to the material of the thermal barrier isl ' ~

It is therefore an object of the present invention to provide am inner liner for firefighter garments, which is free of slippage and fraying between the layers of the garment and which is permeable to air.
The above amd other objects of the present invention may be achieved in a liner for firefighter garments, which comprises a laminate formed of a sheet of textile material derived from m~lltifil y aramid, polyimide, polyamide, polyb. ' 'e or cellulose fire retardamt yarns amd a non-woven textile material in sheet form, and a&esive means enabling the sheet of textile material and the sheet of non-woven material to be laminated m such a ma1mer that the sheet of textile material and the sheet of non-woven textile material, are non-slipping amd non-fraying relative to one amother while enabling the laminate to be air permeable with a minimum of ten (10) cubic feet per minute (CFM) air pPrr ~ y when tested in a~iculdcu.~,c with ASTM

In accvl~l e with a preferred . ~ -~lir- t, the textile material 5 consists of a weave of war,o and weft yarns which are l~;fil ' ' y aramid, polyinude, poly~ or cellulose fire-retardant yarns.
Preferably the textile material has a weight which is less than 4.0 oumces per square yard amd is made of yarn size of 80 to 250 deniers.
In accul,' e with amother . bc ' t, the textile material is a 10 knitting of ' rl-~ y aramid, polyimide, poly~ '~ or polyl,, ' '~ yarns or yarns made of cellulose fire retardant material.
The preferred textile material is a plain weave of aramid yarns, while the preferred non-woven material is made of needle punch aramid, 15 polyimide, polyb~ carbon or cullulose fre retardant fibers.
The laminate according to the invention is prepared by any well known l ( process except that the adhesive is deposited such as by spraying so as to produce a large number of bonds, dots or spider web, rather than a . film, thereby enabling the laminate to be 20 air penn~ An example of the adhesive that may be used is a moisture curing PUR prepolymer hot melt adhesive.
