Benefits of technology

The present invention relates to composite materials that use a fibrous face layer combined with an adhesive layer to form a multi-layer structure. The fibrous face layer has loops of fibers that form loops and anchor into the adhesive layer, providing improved surface stability and retention of appearance under repeated loading. The adhesive layer is controlled to not penetrate into the top portion of the face layer, maintaining its textile feel. The fibrous face layer can be made with different types of fibrous layers and can also be embossed for a three-dimensional texture. The composite material can also have a three-layer structure with added structural rigidity. The invention provides a method for preparing the composite material by embedding the adhesive layer into the face layer and / or the backing layer using pressure and heat. The adhesive layer can be pre-integrated onto the layers or simultaneously penetrate into both layers during lamination. The adhesive layer can contain non-adhesive reinforcing or blended components and can also contain adhesive components in sufficient quantity to anchor and envelope the legs of the surface fiber loops descending into it.

Problems solved by technology

However, these products lack the textile hand, softness or sound dampening qualities of textile products.
Compared to rigid solid surfaced products, however, these floor coverings are less durable, tend to lose their texture with heavy use, because the pile tends to mat or to be crushed with heavy traffic, tend to collect dust and dirt, provide spaces that allow the growth of bacteria, and are difficult to clean and sanitize.
These hybrid structures, however, merely reduce but do not eliminate the limitations of regular tufted, velour, or flocked textile surfaces.
However, these floor covering products largely have a stiff leathery appearance rather than a soft textile feel, and the cost of preparing dimensionally-stable dense fibrous products, combined with the cost of impregnating and heat setting can be very high.
The resultant floor covering products combine the qualities of carpet with the solidity of vinyl or rubber, but lack the textile quality and aesthetics of carpets.
Laminates having a flat fabric face, however, tend to delaminate or fray at the edges unless the fabric is thoroughly impregnated with adhesives.
Unfortunately, impregnation with adhesives adversely affects the textile feel and cushioning quality of the laminate.

example 1

[0085] A blend of 80% 1.5 denier 1.5 inch polyester fibers and 20% 1.5 denier 1.5 inch polypropylene fibers is carded and lapped into a structure weighing approximately 8 oz / sq.yd. This face layer is then needled from one side only with 1,500 penetrations / sq.in. forming a dense surface and a very fur-like backface with many free ends and loops, as shown in FIG. 6.

[0086] A second blend of 80% 15 denier, 1.5 inch cut polyester and 20% 1.5 denier 1.5 cut polypropylene fiber is carded and lapped into a 24 oz / sq.yd batt and needled with 300 penetrations per square inch from one face to form the backing layer.

[0087] A dual layer of 0.05 inch thick polyethylene utility films is placed between the face layer and the backing layer, with the needled sides of the face layer and the backing on the outside and pressed with a plate heated to about 200 degrees C. placed against the face layer, at 1000 psi for 3 seconds. The plate facing the backing is at room temperature. The product is solidly ...

example 2

[0088] The face layer of Example 1 is needled into the adhesive layer before laminating onto the backing layer. The stability of the surface is superior to Example 1. Delamination without destroying the layers is even more difficult. The surface is fibrous, smooth, free of adhesive and traffic-wear and edge-fraying resistant. The fibrous height above the adhesive penetration is approximately 0.9 mm.

example 3

[0089] The needled face layer of Examples 1 and 2 is needled directly through the dual adhesive layer and into the backing (FIG. 12) before the hot pressing process. The product has a textile feel and excellent durability and is delamination resistant.

Abstract

The present invention is directed to multiple layer composites (10) suitable for use as wall and floor coverings, among other uses, that provide a strong durable structure and a soft textile or fabric face. The composite includes a face layer (12) bonded to an adhesive layer (22) such that the adhesive layer (22) penetrates into the face layer (12). The face layer (12) can have legs (19, 34) extending there from, and such legs (19, 34) are anchored by the adhesive layer to provide stronger attachment between the adhesive layer and the face layer. A backing layer (26) may also be provided in contact with the adhesive layer (22) such that the adhesive layer also embeds into the backing layer (26), and the legs (19, 34) extending from the face layer may penetrate into the backing layer.

Description

TECHNICAL AREA [0001] The present invention relates to fabric-faced laminates for use as floor coverings. BACKGROUND [0002] Floor coverings are generally selected based upon a combination of factors including aesthetic features such as the look and feel of the floor covering and functional qualities such as retention of surface appearance, stain resistance, moisture resistance, ease of cleaning, and resistance to collection of dirt. For example, floor covering installations in high traffic areas or areas prone to moisture and stains such as kitchens generally use solid surface cover materials for the flooring or interior wall coverings such as wood, metal, marble, ceramic tile, vinyl or rubber. These products retain their surface appearance after heavy use and they are simple to keep clean. They also are resistant to stains and moisture, and less prone to harboring bacterial growth. However, these products lack the textile hand, softness or sound dampening qualities of textile produ...
