Patent Application
20140287186
Aspects described herein relate generally to carpet designs having an at least partially exposed primary backing layer incorporated into the carpet design and methods for manufacturing the same.
As illustrated in
The face of a tufted carpet can generally be made in three ways. First, for loop pile carpet, the yarn loops formed in the tufting process can be left intact. Second, for cut pile carpet, the yarn loops can be cut, either during tufting or after, to produce a pile of single yarn ends instead of loops. Third, some carpet styles can include both loop and cut pile. One variety of this hybrid is referred to as tip-sheared carpet where loops of differing lengths can be tufted followed by shearing the carpet at a height so as to produce a mix of uncut, partially cut, and completely cut loops. Alternatively, the tufting machine can be configured so as to cut only some of the loops, thereby leaving a pattern of cut and uncut loops. Whether loop, cut, or a hybrid, the yarn on the back side of the primary backing material can comprise tight, unextended loops.
The combination of tufted yarn and a primary backing material without the application of an adhesive backing material or secondary backing material is referred to in the carpet industry as raw tufted carpet or greige goods. Greige goods can become finished tufted carpet with the application of an adhesive backing material and an optional secondary backing material to the back side of the primary backing material. Finished tufted carpet can be prepared as broad-loomed carpet in rolls typically 6 or 12 feet wide. Alternatively, carpet can be prepared as carpet tiles in varying shapes and sizes.
A substantial demand exists for tufted carpet designs and methods of manufacture that reduce the waste produced over conventional tufted carpet manufacturing methods that makes more efficient use of materials and that results in a lighter weight carpet.
It is to be understood that this summary is not an extensive overview of the disclosure. This summary is exemplary and not restrictive, and it is intended to neither identify key or critical elements of the disclosure nor delineate the scope thereof. The sole purpose of this summary is to explain and exemplify certain concepts of the disclosure as an introduction to the following complete and extensive detailed description.
The present invention is generally directed to a deconstructed tufted carpet in which at least a portion of the primary backing is visible or at least partially visible. In aspects, deconstructed carpet can utilize the primary backing layer as a design element of the overall pattern and styling in order to reduce material use, waste and the ounce weight of the finished carpet and to improve the method of carpet construction. In one embodiment, in order to expose the primary backing, at least some yarn is pulled very low in the desired exposed member pattern areas thereby exposing a desired amount of the primary backing layer. It is contemplated that the primary backing layer can have a color that comprises part of the overall pattern and styling of the carpet.
Additional features and advantages of exemplary aspects of the disclosure will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of such exemplary aspects. The features and advantages of such aspects may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. These and other features will become more fully apparent from the following description and appended claims, or may be learned by the practice of such exemplary aspects as set forth hereinafter.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate several aspects described below and together with the description, serve to explain the principles of the invention. Like numbers represent the same elements throughout the figures. The patent or application file contains at least one drawing executed in color. Copies of this patent or patent application publication with color drawing(s) will be provided by the Office upon request and the payment of the necessary fee.
The present invention can be understood more readily by reference to the following detailed description, examples, drawing, and claims, and their previous and following description. However, before the present devices, systems, and/or methods are disclosed and described, it is to be understood that this invention is not limited to the specific devices, systems, and/or methods disclosed unless otherwise specified, as such can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting.
The following description of the invention is provided as an enabling teaching of the invention in its best, currently known embodiment. To this end, those skilled in the relevant art will recognize and appreciate that many changes can be made to the various aspects of the invention described herein, while still obtaining the beneficial results of the present invention. It will also be apparent that some of the desired benefits of the present invention can be obtained by selecting some of the features of the present invention without utilizing other features. Accordingly, those who work in the art will recognize that many modifications and adaptations to the present invention are possible and can even be desirable in certain circumstances and are a part of the present invention. Thus, the following description is provided as illustrative of the principles of the present invention and not in limitation thereof.
As used throughout, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a needle bar” can include two or more such needle bars unless the context indicates otherwise.
Ranges can be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, another aspect includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another aspect. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint.
As used herein, the terms “optional” or “optionally” mean that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.
As used throughout, the term “carpet tile” refers to carpet tiles and other conventional textile-face modular flooring tiles.
As used herein, the definition of the term “color” is referenced in terms of the CIELAB color scale, which was created by the International Commission on Illumination (CIE). The CIELAB color scale provides a uniform scale for measuring and comparing the color values of different samples. Three different color measurements are used to determine the CIELAB color value of a given sample: 1) a white-black color measurement; 2) a red-green color measurement; and 3) a yellow-blue color measurement. The white-black color measurement represents the amount of white present in the sample relative to the amount of black present in the sample. The red-green color measurement represents the amount of red present in the sample relative to the amount of green present in the sample. The yellow-blue color measurement represents the amount of yellow present in the sample relative to the amount of blue present in the sample. CIELAB color scale values can be obtained using color measurement instruments known in the art, including, for example, HunterLab color measurement instruments.
As used throughout, the terms “tuft”, “tufting”, “tufted”, “tufted-in”, and other verb tenses thereof refer to inserting, pressing, passing, and/or any other conventional process by which yarn is attached or otherwise coupled to the carpet backing.
In one aspect, and as shown in
Referring now to the drawings, in which identical numbers indicate identical elements throughout the various views,
In aspects of the present disclosure, the deconstructed carpet can have the tufting pile heights adjusted over conventional tufted carpet such that a previous medium pile height becomes a low pile height and the previous low pile height becomes very low against the primary backing. It is contemplated that the deconstructed carpet can then be finished similarly to conventional tufted carpet. In light of the present disclosure, one skilled in the art will appreciate that lowering of the pile heights can allow for a reduction in tufted weight. Thus, in another aspect, the ounce weight of the deconstructed carpet can be from about 6 to about 25 oz., optionally, from about 8 to about 16 oz., and, more particularly, about 10 oz. in a patterned deconstructed carpet.
The deconstructed carpet shown in
Each needle can be threaded with a dedicated yarn type (e.g., single color, space dyed, barber pole, etc.) and color(s). In one example, the color shapes of the tufted portion pattern members are formed on the color web by contrast between adjacent yarn colors on a single needle row and by contrast between the yarn colors on the needle bar or needle bars. Thus, the types and colors of yarn 24 used should be selected to achieve a desired contrast between areas of the desired pattern design of the carpet. For example, at least one color in the one or more tufted portion pattern members should be used to achieve the desired color contrast against the colored primary backing. However, it is optional, but not necessary, to use more than one color to achieve the desired color contrast. For example, the primary backing color should differ from the color therein the tufted portion pattern members in either one of, or a combination of, hue, chroma, and/or value. In one exemplary aspect, the primary backing color differs from the plurality of yarns that form the at least one color in the tufted portion pattern members.
Any thread-up of the machine may be used in accordance with this invention so long as the resultant web forms a carpet in accord with the directed color and texture design of the deconstructed carpet. In aspects, deconstructed carpet allows a singular color yarn to be used and the exposure of the primary backing creates the desired pattern design of the carpet by the color contrast between the color of the yarn and the color of the primary backing. It is also contemplated that multiple colored yarns can be used; however, one skilled in the art will appreciate that in a deconstructed carpet, multiple colored yarns are no longer a requirement to provide pattern.
As noted above, the characteristic of the deconstructed carpet 10 can be further controlled by varying the height of the yarn, i.e., controlling the pile height of the deconstructed carpet. The longer the length of yarn that is pushed through the primary backing, the greater its height in the finished carpet. In the exemplary deconstructed carpet, at least some primary backing can be visible in some portions of the tufted portion pattern members, and some areas can show substantially only primary backing.
In other aspects, either broadloom carpet or carpet tiles can be manufactured using the deconstructed carpet. In exemplary aspects, the carpet tile 11 can be substantially rectangular (having a length 18 and a width 19 that are substantially different). It is also contemplated that the carpet tile 11 can be substantially square (having a length 18 and a width 20 that are substantially equal). However, it is contemplated that the carpet tile 11 can have any desired shape, including a desired conventional shape or a desired irregular and/or organic shape. In further exemplary aspects, it is contemplated that the carpet tile 11 can have a tufted face, a woven face, or a fusion-bonded face that is formed according to conventional methods. In an additional exemplary aspect, it is contemplated that at least a portion of the face of the carpet tile 11 can be printed using conventional methods.
Although several embodiments of the invention have been disclosed in the foregoing specification, it is understood by those skilled in the art that many modifications and other embodiments of the invention will come to mind to which the invention pertains, having the benefit of the teaching presented in the foregoing description and associated drawings. It is therefore understood that the invention is not limited to the specific embodiments disclosed herein, and that many modifications and other embodiments of the invention are intended to be included within the scope of the invention. Moreover, although specific terms are employed herein, they are used only in a generic and descriptive sense, and not for the purposes of limiting the described invention.
This application claims the benefit of U.S. Provisional Application No. 61/794,873, filed Mar. 15, 2014, which is hereby incorporated herein by reference in its entirety.
