DESCRIPTION OF THE PREFERRED EMI30DII1~Il:Nrl'S
Referring now to Figures 1 to 3, there is shown a preferred embodiment of a stretchable composite thermal insulation material 10 suited for use in cold weather garments, sleepin<~ bags, horse blankets and the like. 'hhis is n<>t intc;nded to constitute an exhaustive list of the potential applicatiuns of the present r nventton.
The composite material 10 generally comprises a stretchable fibrous insulator I2 and a stretchable substrate 14. The insulator 12 and the substrate 14 arc preferably at least 5 % stretch. As will be seen hereinafter, the stretchable insulator 12 and the stretchable substrate 14 are secured together such that the stretchability of both materials is preserved in the assembled product, thereby allowing for the fabrication of stretchable thermally insulated products, such as cold weather jackets and sleeping bags.
The substrate 14 is preferably provided in the form of a stretchable woven fabric of synthetic yarns, such as polyester. Depending on the intended application, the stretchable fabric may also be chosen to have breathable, waterpruul~
or other suitable properties. In any event, the fabric is selected to be stretchable alc»lg at least one axis, which typically corresponds to the longitudinal direction ol~ the yarns thereof. The density of the labric is selected to substantially prevent the fibers of the insulator 12 to migrate therethrough. The density is preferably less than 1 CPM. According to further embodiment of the present invention, the substrate could be provided in the form of a stretchable membrane or a coatin~~.
According to the preferred embodiment, the stretchable insulator 12 is prOVlded 111 tile fOrlll Of a CO11t1nlIOllS tvllalllellt 111slllat1011 nlaterlal lllade Of flberS Of Lllflnlte length.

As opposed to the widely commercially available insulators made of staple or chopped fibers, continuous filament insulators exhibit relatively high stretchability properties mainly along the longitudinal axis of the filaments. One such continuous filament insulation material is manufactured and sold under the trademark POLARGUARD. This material is non-woven continuous filament polyester composed of hollow crimped continuous filaments arrayed 2 5 essentially parallel to one another.
While continuous filament insulation materials and stretchable fabrics are individually available on the market, it has been heretofore unknown to combine them in such a way as to obtain a composite material oflering high thermal insulation properties, while being stretchable. In the past, the stretchability of continuous 3 0 filament insulation materials has simply never been exploited.

It 1S lllldeTStOOd that the COIltIllltOlIS tilamcnt insulation material 12 and the stretchable substrate 14 are oriented relative to one another so as to be stretchable;
along a same direction, which generally corresponds to the direction along which the composite material 10 will be the most solicited in use.
To preserve as much stretch as possible and at the same time insure porosity, a spaced-apart hot melt glue pattern 1 G is preFerably unitbrmly applied over one face of the substrate 14 to bond the continuous lilatnent material 12 thereto. ~l'he spaced-apart pattern leaves ope~'1 areas which permits longitudinal stretching of tllc;
eontimlous filaments after it has been bonded to the stretchable substrate 14.
The glue pattern 16 Can be applied to the substrate 14 utilising a conventional en~~raved roller.
Alternatively, a jet spray system or an ultrasound system could be used to apply the spaced-apart hot melt glue pattern 1 C. Other lamination processes are also contemplated.
The illustrated hot melt glue pattern is a spaced-apart dot pattern.
However, it is understood that other patterns could be used as well.
As shown in r'ig. 2, once so assembled tobcther, the continuous filament material 12 and the substrate 14 are jointly stretchable when subject to external longitudinal stretching forces. A second stretchable substrate (not shown) could be similarly secured to the other face oFthe continuous Glamcnt material 12 to form a triple layer stretchable material.
The continuous filament insulation material could also be attached to the substrate 14 by stitching, but the stretch properties of the composite material would then be inferior to that of the corresponding bonded version thereof.
The above described composite material 10 could, For instance, he used as the liner of a cold weather jacket. The substrate 14 would loan the inner Fabric of the jacket. The other face of the stretchable insulation 12 would be bonded as per the way described hereinabove to a stretchable outer fabric forming the outer

8. An article of clothing as defined in claim 7, means for joining the stretchable batting to the stretchable fabric while preserving the stretchability of the batting in the article of clothing.
9. An article of clothing as defined in claim 8, wherein the stretchable batting is secured over a surface thereof to the stretchable fabric by discrete spaced-apart points of attachment.
10. An article of clothing as defined in claim 9, wherein a spaced-apart adhesive dot-like pattern is applied over one face of said fabric.
11. An article of clothing as defined in claim 7, wherein the stretchable fabric has a density selected to substantially prevent filaments of the stretchable batting to migrate through said stretchable face fabric.
12. A stretchable composite material comprising: a batting superposed on a fabric, the batting and the fabric being respectively stretchable along at least first and second axes, and means holding the batting and the fabric together with said first and second axes thereof extending in a same direction.
13. A stretchable composite material as defined in claim 12, wherein said holding means comprise a pattern of spaced-apart adhesive points provided over a surface of said fabric.
