Embodiments of the subject matter disclosed herein relate to colored or printed composite textile fabrics used in flooring, surface coverings, upholstery, and other uses.
When a fabric is printed with a uniform color or with a color pattern applied to the top surface, the applied color or color pattern does not always extend into the lower strata of the fabric. In portions of the fabric where the color or color pattern does not extend into the lower strata, the original color of the fibers or yarns of the fabric is exposed at gaps created by the parting of the fibers or yarns. Exposure of the original color of the fibers degrades the appearance of the color or color pattern applied to the top surface.
Fabrics having a uniform surface color or color scheme and that are conformable, moldable or embossable with a relatively deep heated tool tend to show undesirable gaps at the stretched areas. These undesirable gaps result from the parting of the fibers or yarns of the fabrics in the stretched areas. The gaps formed during embossing can also create holes at the peripheries of the depressed areas of the fabric and can extend to the surface of the fabric at elevated areas as the top surface is stretched by the embossing action. In addition to parting of the fibers occurring as a result of molding or embossing, parting of the fibers or yarns can occur over time during use of the fabric.
When the fabric is attached to a backing layer during embossing, the backing can become visible at the gaps created by the parting of the fibers or yarns. Unless the exposed backing has a uniform color matching the color or color pattern applied to the top surface, the exposed backing creates an undesirable contrast with the top surface of the fabric. As any backing applied to the fabric is typically required to have special properties, coloring that backing to match the color or color pattern applied to the top surface is complicated, impractical, and costly.
Therefore, improved fabrics and methods for making improved fabrics that are less complicated and more economical are desired where the improved fabrics have a uniform color or color pattern on the top surface and that avoid or mask gaps or holes or gaps that cause a loss of color or printed design uniformity on the top surface. These improved fabrics would include conformable, moldable, and deeply embossable composite fabrics.
Exemplary embodiments are directed to conformable, colored multilayer textile fabric composites, to methods of making conformable, colored multilayer composite textile fabrics, and to methods for using the conformable, colored multilayer composite textile fabrics. In an exemplary embodiment of a method for making a conformable, colored multilayer composite textile fabric, a colored or color-carrying layer is combined with a textile fabric. Preferably, the colored or color-carrying layer is a low-melting colored or color-carrying layer (hereinafter “LMCC”). In one embodiment, the color-carrying layer is an adhesive layer. The color-carrying layer includes or contains coloring elements. The coloring elements are incorporated into the color-carrying layer by dyeing the color-carrying layer with a desired color or colored pattern, printing the color-carrying layer with a desired color or color pattern, injecting the color-carrying layer with a desired color or color pattern or mixing the color-carrying layer with color pigments. The textile fabric includes a first color or first colored pattern on at least a portion of the top surface of the textile fabric, and the coloring elements incorporated into the color-carrying layer have a second color or a second colored pattern. The second color approaches, matches, is aesthetically compatible with, or is contrasting to the first color on the top surface of the textile fabric. Therefore, the color-carrying layer introduces a shade of color into the textile fabric composite that is compatible with or matches the face color or pattern of the textile fabric.
The second color incorporated into the color-carrying layer is exposed along portions of the top surface of the textile fabric that are the parted under pressure applied by embossing or traffic passing over the top surface. Exposure of the second color masks the parted portions of the top surface. In addition, the color-carrying layer may reduce or eliminate holes created in the depressed embossed areas of the textile fabric. In one embodiment, the color-carrying layer is added to the textile fabric, for example, under the textile fabric adjacent a bottom surface that is opposite the top surface, before the resulting textile fabric composite is exposed to an embossing or molding process. The embossing or molding process melts the color-carrying layer, e.g., the LMCC or LMCC adhesive layer. The melted color-carrying layer, e.g., the melted adhesive, propagates through the textile fabric toward the top surface. In one embodiment, the propagation of melted adhesive is controlled by adjusting the melt index of the adhesive, the weight of the adhesive, the applied temperature, the applied pressure and combinations thereof. These adjustments allow the melted adhesive to proceed towards the upper surface of textile fabrics having a printed color or printed color patterns, compensating for the lack of face color within the lower strata of the textile fabric and eliminating any color gaps appearing along the top surface.
In one embodiment, the color-carrying layer, including an LMCC layer and an adhesive layer, is contained within the textile fabric between the top surface and the bottom surface. Alternatively, the color-carrying layer is placed above one or more separate internal sublayers contained within the textile fabric, i.e, between the internal sublayers and the top surface. Therefore, the adhesive layer is disposed between the internal sublayers and the top surface of the textile fabric. Suitable internal sublayers include, but are not limited to, the stitching substrate of a stitched fabric, the primary backing of a tufted fabric and the reinforcing mid-layer of a needle-punched fabric. As with color-carrying layers, including LMCC or adhesive layers, placed below the bottom surface of the textile fabric, the melted color-carrying layer proceeds upwards through the fabric layer toward the colored tope surface upon embossing or molding, masking gaps along the top surface that lack color.
In one embodiment, color-carrying layer is a polymeric film or a polymeric fabric. In one embodiment, the color-carrying layer is a layer of powders or freeze ground particles mixed with color pigment. In one embodiment, the color-carrying layer is melt-extruded or coated from a solution onto the bottom surface of the textile fabric. In one embodiment, the color-carrying layer is pre-melted and pressed into the bottom surface of the textile fabric prior to molding or embossing. In one embodiment, the color-carrying layer is pre-pressed into the textile fabric, and the textile fabric is maintained at a temperature above the color-carrying layer melting point until the resulting textile fabric composite is embossed. In one embodiment, the color-carrying layer is applied in a melted state, is subsequently cooled below the color-carrying layer melting point following application or incorporation into the textile fabric and is re-melted during subsequent embossing of the resulting textile fabric composite. In one embodiment, a backing is attached to the textile fabric and color-carrying layer with embossing.
In one embodiment, the textile fabric is a woven fabric or knit fabric formed with yarns. In one embodiment, the textile fabric is a tufted fabric or stitch-bonded fabric containing yarns and a primary substrate or backing. The substrate or backing can be a fibrous substrate or backing or a non-fibrous substrate or backing.

In one embodiment, the textile fabric is a bonded or spunlaced nonwoven fabric formed with continuous filaments, staple fibers or combinations thereof.
In one embodiment, the weight of the color-carrying layer, the melt index of the color-carrying layer, or both the weight of the color-carrying layer and the melt index of the color-carrying layer are adjusted to control a degree of penetration of the melted color-carrying-layer through the textile fabric towards the top surface. In one embodiment, the color-carrying layer is an adhesive layer, and melted adhesive from the color-carrying layer layer placed adjacent the bottom surface of a tufted or stitch-bonded textile fabric penetrates the substrate or primary backing used to form the textile fabric but does not propagate completely to the top surface.
In one embodiment, the textile fabric combined with the color-carrying layer are embossed using a highly conformable and recoverably-elastic back-up tool such as silicon rubber. Use of the back-up tool allows embossing to depths approaching or exceeding a thickness of the textile fabric. In one embodiment, the color-carrying layer is an adhesive layer, and the textile fabric containing the color-carrying adhesive layer adjacent the bottom surface is attached to a highly-conformable backing during the embossing process, eliminating the need for a separate back-up tool.
In one embodiment, one or more of a proximity of the color-carrying layer to the top surface containing the color or colored pattern, the weight of the color-carrying layer, and the melt viscosity of the color-carrying layer are selected to prevent the melted color-carrying layer from reaching and stiffening the top surface while allowing the melted color-carrying layer to propagate through the textile fabric towards the colored surface. In one embodiment, the color-carrying layer is a partially-open layer with a selected pattern that rises towards the top surface of the fabric to produce a special “phantom” surface effect as the color-carrying layer becomes partially visible among the generally parted surface fibers or yarns.

In one embodiment, a first color pattern is disposed on the top surface. In one embodiment, a plurality of first colors are disposed on the top surface. Similarly, the color-carrying layer can have the second color disposed throughout the color-carrying layer or in at least a portion of the color-carrying layer. In one embodiment, a second color pattern is contained in the color-carrying layer. The second color can be an identical color, a complementary color or a contrasting color to the first color. Similarly, the second color pattern can be an identical color pattern, a complementary color pattern or a contrasting color pattern to the first color pattern. In one embodiment, the color-carrying layer is selected such that the first color and the second color differ by one or more of hue, tint, shade, tone, saturation, lightness, chroma, intensity, brightness and grayscale.
In one embodiment, a color-carrying adhesive layer is selected as the color-carrying layer. In one embodiment, a low melt color carrying-layer or a low melt color-carrying adhesive layer is selected as the color-carrying layer. Other suitable selections for the color-carrying layer include, but are not limited to, a printed fabric, a film, and a film containing color pigments. In one embodiment, the color-carrying layer is formed using powders mixed with colored pigment. Alternatively, the color-carrying layer is formed using particles mixed with colored pigment. In one embodiment, the color-carrying adhesive layer has a color-carrying adhesive layer melting point, and the textile fabric has a textile fabric melting point. The color-carrying adhesive layer melting point is lower than the textile fabric melting point. Therefore, the color-carrying layer can be melted without melting the fibers or yarns of the textile fabric.
The color-carrying layer is spaced from and located below the top surface. In one embodiment, the color-carrying layer is located on a bottom surface of the textile fabric opposite the top surface, for example, by applying the color-carrying layer to the bottom surface. The color-carrying layer can be applied to the bottom surface by melt-extruding the color-carrying layer onto the bottom surface or coating the color-carrying layer onto the bottom surface. Alternatively, the color-carrying layer is located between the top surface and the bottom surface. In one embodiment, the color-carrying layer is placed on a plurality of discrete portions of the bottom surface. For example, the color-carrying layer in the plurality of discrete portions is placed in accordance with a predetermined pattern that creates a phantom effect with the first color. In one embodiment, the first color is disposed at a plurality of locations across the top surface, and the second color is located at a plurality of locations across in the color-carrying layer. The plurality of locations across the top surface align with the plurality of locations in the color-carrying layer when the textile fabric is combined with the color-carrying layer. The textile fabric can be combined with a plurality of discrete color-carrying layers. The plurality of discrete color-carrying layers can be located at two or more separate distances from the top surface and at different locations across the textile fabric. When combining the textile fabric with the color-carrying layer comprises a distance between the color-carrying layer and the top surface across the textile fabric can be varied, or a thickness of the color-carrying layer across the textile fabric can be varied. In one embodiment, a distance between the color-carrying layer and the top surface across the textile fabric and a thickness of the color-carrying layer across the textile fabric are varied.
In one embodiment, when the textile fabric is a stitch-bonded fabric, the color-carrying layer is used as a substrate to form the stitch-bonded fabric. Alternatively, the color-carrying layer is placed against the stitching substrate such that the color-carrying layer is disposed between the stitching substrate and the top surface. In one embodiment, when the textile fabric is a tufted fabric, the color-carrying layer is used as a primary backing to form the tufted fabric. Alternatively, the color-carrying layer is placed against the primary backing during tufting such that the color-carrying layer is disposed between the primary backing and the top surface. In one embodiment, when the textile fabric is a needle-punched fabric, the color-carrying layer is incorporated within the needle-punch fabric between the top surface and the bottom surface.
The color-carrying layer is then partially propagated through the textile fabric toward top surface, for example toward the portion or portions of the top surface containing the first color. Propagation of the color-carrying layer is accomplished by directing heat, pressure or heat and pressure toward the top surface, bottom surface or the top and bottom surfaces of the textile fabric. In one embodiment, heat or heat and pressure are applied to melt the color carrying layer such as a low-melting color-carrying adhesive layer and to propagate melted color carrying layer or low-melting color-carrying adhesive through the textile fabric. In one embodiment a lamination process, a molding process or an embossing process is used to propagate the color-carrying layer toward to top surface. A three-dimensional pattern can be formed in the textile fabric composite, either after propagating the color carrying layer or simultaneously with propagating the color-carrying layer. During propagation of the color-carrying layer through the textile fabric, the extent of propagation of the color-carrying layer through the textile fabric toward the top surface can be controlled. The extent of propagation can be controlled by adjusting a melt index of the color-carrying layer, adjusting a proximity of the color-carrying layer to the top surface, adjusting a weight of the color-carrying layer and combinations thereof. The extent of propagation can also be controlled by applying compressed air or vacuum to one of the top surface and the bottom surface to promote molten flow in a preferred direction.
