Abstract
The present invention provides a textured non-woven insulating laminate lining material which is light weight. The material has a layer of flexible plastic material, on one side upon which is placed a thin layer of thermally reflective metal. Fiber wadding is placed on the side remote from the metal reflective layer, with fibers extending from the wadding through the plastic and reflective layer to form a light nap on the side of the reflective layer, to not only give the material the desirable characteristics of touch and absorbancy normally associated with fine fabric lining and enhance the insulating properties of the material, but also act as a wick, picking up moisture, e.g. perspiration, and transmitting it through the laminate to the fiber, away from the body. The nap is of sufficient weight to permit adequate wicking while permitting exposure of the reflective metallic material. Additionally, the needle punching of the individual fibers through the plastic and metal layer helps secure the wadding to the back of the plastic and ties in the layer of thin metal to the plastic substrate. The layer of metal can additionally be secured to the base plate by means of vacuum plating or laminating. Further, the present invention sets forth a method of manufacturing such material by placing a layer of thermally reflective metal on one surface of a strong flexible non-resilient thin plastic sheet, and placing a layer of fiber wadding on the opposite surface of the flexible thin plastic sheet. The layer of fiber wadding is needle punched, to force individual fibers through the thin plastic sheet and the layer of reflective metal, to produce the laminate, and to provide a fiber nap extending from the thin plastic metal. The layer of reflective metallic material may also be secured to the thin plastic substrate by vacuum plating or bunding prior to the application of the fiber wadding.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to laminated fabric materials, especially for use as a lining in clothing to provide insulation for the wearer and to protect against moisture build up against the skin of the wearer.
This invention also relates to the method of manufacturing a laminated fabric material, especially for use as a lining in clothing.
2. Description of Prior Art
Linings are often put in apparel for purposes of comfort, durability, and insulation. This is especially true in apparel that is used in colder temperature areas. The linings provide for thermal insulation and are often used to capture and form various insulating materials, such as down or other loose materials that provide air pockets as an insulator.
The linings also are often non-porous, to provide a wind screen to assist in the capture of body heat of the wearer of the garment. However, because these linings are non-porous, moisture from perspiration, for instance, collects on the surface and remains in contact with the body of the wearer.
Linings often prove difficult, either to manufacture or to properly install in the garment, or once installed to provide the durability and insulating properties necessary. For example, plush linings--the types used in down jackets or such--require an extensive amount of individual sewing in order to form pockets in which the light insulating material is captured. This material must be packed and blended in a uniform manner, often by hand, and then a separate intricate sewing procedure carried out to form the appropriate containers or pockets. Once the garment is in use, it is notorious that the individual threads, which form the design to form the various pockets, start unraveling and the insulating material then becomes free to travel within the lining of the jacket, and the lining loses much of its effectiveness. Additionally, such linings are bulky and often uncomfortable for the wearer.
The non-porous windscreen type of linings also have proved to be less than satisfactory since they usually do not absorb moisture. Therefore, if the wearer of the garment perspires, the perspiration stays on the inside of the jacket, in contact with the skin of the wearer, making him feel uncomfortable.
Attempts to use reflective materials in the lining in order to reflect back the body heat to assist in the thermoinsulation procedures have often been unsuccessful. The reflective material must be flexible enough to provide comfort, but often thin layers of reflective metals tend to crack or break so as to scratch or irritate the wearer. Also, they are subject to corrosion from the normal prespiration of the wearer.
With respect to the manufacturing of these lining materials, as mentioned above, they often require an inordinate amount of hand work in their assembly and manufacture, which leaves the manufacturing process susceptible to wide variations in the properties of the finished product and its quality control. Additionally, the actual fabrication process often requires handling large quantities of loose bulk material which is difficult to effectively manipulate, and which can produce health hazards because of excessive amounts of dust generated from such material.
More specifically, there are numerous prior art references which describe insulating fabric laminates, see for example, the following U.S. Pat. Nos.
3,222,243 to Gaston et al;
3,461,026 to Schick;
4,062,993 to Seward;
4,170,676 to Thomas;
4,315,048 to Beghelli et al;
4,395,455 to Frankosky;
4,420,521 to Carr;
4,433,019 to Chumbley; and
4,446,189 to Romanek.
None of these references teach or suggest the insulating fabric of this invention, the combined advantages obtained therefrom, and the unique process of making this fabric.
The most relevant reference is Seward. Seward teaches the manufacture of carpeting using a laminate formed of a heavy base fabric with a heavy foil overlay with a thick pile of heavy fiber batting placed on top of the foil and then some of the batting is needle punched through the layers to provide a continuous layer of fibers on the underside of the base fabric. This continuous layer of fiber bat on the underside of the fabric base is used for adhering the laminate to a latex base after the laminate has been needle punched or power tufted to provide the relatively thick and heavy rug nap, and to anchor the rug nap into the latex. The upper layer of densified non-woven bat is used to fill in the spaces between the fibers forming the rug tufts and is the receptacle for dye in order to aesthetically disguise the spaces between the rug tufts. The metallic foil is used primarily during the manufacturing process or pallet tufting of the carpet fibers to act as a heat sink to dissipate the frictional heat of the tuft fibers being forced through the laminate which could either ignite or melt the materials forming the laminate.
The metallic foil serves absolutely no function of insulation for the finished product as is the case in the present invention. Additionally, as pointed out above, the metallic layer is completely buried and has no relationship with the ambient environment of the material, i.e., it is non-reflective and covered.
SUMMARY OF THE INVENTION
Accordingly, in order to overcome the problems of the prior art, the present invention provides a textured non-woven insulating laminate lining material which is light weight. The material has a layer of flexible plastic material, on one side upon which is placed a thin layer of thermally reflective metal. Fiber wadding is placed on the side remote from the metal reflective layer, with fibers extending from the wadding through the plastic and reflective layer to form a light nap on the side of the reflective layer, to not only give the material the desirable characteristics of touch and absorbancy normally associated with fine fabric lining and enhance the insulating properties of the material, but also act as a wick, picking up moisture, e.g. perspiration, and transmitting it through the laminte to the fiber, away from the body. The nap is of sufficient weight to permit adequate wicking while permitting exposure of the reflective metallic material. Additionally, the needle punching of the individual fibers through the plastic and metal layer helps secure the wadding to the back of the plastic and ties in the layer of thin metal to the plastic substrate. The layer of metal can additionally be secured to the base plate by means of vacuum plating or laminating.
Further, the present invention sets forth a method of manufacturing such material by placing a layer of thermally reflective metal on one surface of a strong flexible non-resilient thin plastic sheet, and placing a layer of fiber wadding on the opposite surface of the flexible thin plastic sheet. The layer of fiber wadding is needle punched, to force individual fibers through the thin plastic sheet and the layer of reflective metal, to produce the laminate, and to provide a fiber nap extending from the thin plastic metal. The layer of reflective metallic material may also be secured to the thin plastic substrate by vacuum plating or bunding prior to the application of the fiber wadding.

DESCRIPTION OF THE PREFERRED EMBODIMENT
The textured non-woven insulating laminate fabric of this invention comprises, as a first layer or base material, a layer of a continuous pliable non-woven non-metallic material referring to FIGS. 1-3, this is generally referred to as 40. This fabric base 40 may be composed of any of a wide variety of materials, either woven or non-woven, of natural or synthetic origin. Thus the base material may consist of diverse materials such as jute, cotton, wool, rayon, nylon, polypropylene, polyethylene, polyester, acrylics, or modified acrylics, or mixtures thereof. The highly preferred base material is an extremely high density polyethylene, known as Tyvek (trademark of E. I. Dupont DeNemours), and in particular Tyvek 14. The thickness of this base material is ordinarily in the range of about 0.05 inch to about 0.010 inches, and in the preferred embodiment of this invention about 0.08 inches. This base material is generally moisture impermeable, pliable, puncturable, flexible, and quite strong, e.g., tear resistant.
A continuous layer of heat reflective metal foil 50 is bonded to or layed over one side of the pliable non-woven non-metallic sheet 40. This foil sheet 50 is a reflective pliable metallic foil, such as an aluminum foil. The metallic foil is usually in the range of thickness from about 0.,005, to about 0.010 inches, and in the preferred embodiment herein about 0.0075 inches.
A layer of fiber wadding 30 is placed on the other side of the non-woven non-metallic sheet 40. The fiber wadding 30 can be composed of natural or synthetic fibers, such as cotton, wool, rayon, nylon, polypropylene, polyester, acrylic fibers, modified acrylics, or mixtures of various fibers. Typically the length of the fibers in this fiber wadding can have a wide range.
Many densities and thicknesses of wadding are suitable. In the preferred embodiment the wadding is a commerically available wadding of polyester with a weight of 3 ounces per square yard and a thickness of approximately a quarter of an inch.
A nap of fibers 60 extends from the layer of metal foil 50. The nap 60 is formed from fibers of the layer of wadding 30 passing through the layer of continuous pliable non-woven non-metallic material 40 and the layer of metal foil 50. The fibers of the nap 60 act to carry moisture past the reflective sheet 50 and layer of pliable continuous non-woven non-metallic material 40 to draw water or perspiration from the wearer to the outer layer.
The layer of continuous pliable non-woven non-metallic material 40, the heat reflective metal foil 50, and the fiber nap 30 are bonded together mechanically by means of needle punching, wherein a plurality of needles 70 are punched through the composite of fiber wadding 30, foil 50, and base material 40, as the composite is incrementally moved between strokes of the needles 70. Fiber strands 60 are pulled or pushed to the top of the metallic layer 50, leaving a securely mechanically bonded composite which, becomes covered with a nap of fibers 60 from the fiber wadding 30 below.
The thickness of the wadding 30 placed upon the base material 40 is generally, many times, the thickness desired in the final product as the needle punching operation substantially reduces the thickness of the composite as an incident to interlocking of the fibers.

As can be seen from the above description, it is clear that all of the objects of the invention are accomplished by the present invention.
The material of the invention is suitable for use as a lining for garments or apparel and is easy to work with. The lining is a good heat insulator and it does not get damp or clammy against the body from the perspiration of the wearer. Further, the material has reflective properties which reflect body heat back to the wearer, and therefore, takes it an extremely efficient material for an insulation in the lining of apparel. This is produced by the nap coacting with the reflection layer to maintain reflectivity. However, even though it has a foil surface, the material has a nice feel or touch to the wearer and will not scratch or irriate the wearer. The material is easy to work with and to use in manufacturing processes. It is not bulky and does not require chain stitching to keep the fabric in tact. However, it does allow for moisture absorption to enhance the comfort of the wearer. Additionally, the structure of the material tends to make the various layers adhere fairly closely to each other without delamination or separation of the various layers. The finished material is relatively wind resistant and is lightweight and so is ideally suitable for insulating purposes. As previous mentioned, because of the sturdiness and the strength of the material, its ease of use and its construction, it can stored for extended periods of time without decomposition or deterioration of its qualities. Also, it can be manufactured over wide ranges of performance standards. The wicking action of the knap is excellent because it draws moisture away from the skin of the wearer of the garment. Additionally, the extension of the knap beyond the foil tends to produce a thermal insulating layer of air pockets and also protects the foil layer from cotact with the skin which would tend to wear it away or possibly corrode the material.
Additionally, the method of manufacturing the device is beneficial in that the amount of cushioning and absorbing material can easily be varied; the absorbancy of the finished product can easily be adjusted during the manufacturing process; the manufacturing process requires a minimum of hand operations and can be highly automated and is very accurate and easily controlled.
Although a preferred embodiment of the invention has been disclosed and described in detail herein, it should be understood that this invention is in no sense limited thereby and its scope is to be determined by that of the appended claims.
