DETAILED DESCRIPTION

Referring now to the figures, and in particular to FIGS. 1 and 2 , there is shown an embodiment of the present invention illustrated as the textile 10 , having a first side 11 and a second side 12 . The textile 10 generally comprises a first yarn set 100 interwoven with a second yarn set 200 .

The first yarn set 100 includes a plurality of first yarn subsets 110 and a plurality of second yarn subsets 120 . The first yarn subsets 110 each include individual first subset yarns 111 - 116 that are substantially parallel and are disposed at a substantially even spacing. The second yarn subsets 120 each include individual second subset yarns 121 - 126 that are substantially parallel and are disposed at a substantially even spacing. The first yarn subsets 110 are substantially parallel to, alternatively positioned with the second yarn subsets 120 . The spacing of the individual first subset yarns 111 - 116 and the individual second subset yarns 121 - 126 are such that the individual first subset yarns 111 - 116 and the individual second subset yarns 121 - 126 are substantially even spaced.

The second yarn set 200 includes a plurality of first yarn groupings 210 , second yarn groupings 220 , first displacement yarns 230 , and second displacement yarns 240 . The first yarn groupings 210 each include individual first grouping yarns 211 - 213 , that are parallel and substantially in contact along the length of those yarns. The second yarn groupings 220 each include individual second grouping yarns 221 - 223 , that are parallel and substantially in contact along the length of those yarns. The first yarn groupings 210 and the second yarn groupings 220 are positioned substantially parallel to each other, and with a first displacement yarn gap 21 between the first yarn groupings 210 and the second yarn groupings 220 , and a second displacement yarn gap 22 between the second yarn groupings 220 and the first yarn groupings 210 .

Referring now to FIGS. 1 , 2 , 3 , and 4 A-L, the individual first grouping yarns 211 - 213 and the individual second grouping yarns 221 - 223 of the second yarn set 200 are oriented substantially perpendicular to the individual first subset yarns 111 - 116 and the individual second subset yarns 121 - 126 of the first yarn set 100 . The individual first grouping yarns 211 - 213 of the second yarn set 200 are interwoven with the individual first subset yarns 111 - 116 of the first yarn set 100 , as illustrated in FIGS. 4A-4F . The individual second grouping yarns 220 of the second yarn set 200 are interwoven with the individual second subset yarns 120 of the first yarn set 100 , as illustrated in FIGS. 4G-L .

The first displacement yarns 230 are each disposed in one of the first displacement yarn gaps 21 of the second yarn set 200 , and are interwoven with the individual first subset yarns 111 - 116 and the individual second subset yarns 121 - 126 , as illustrated in FIGS. 4A-4L . The second displacement yarns 240 are each disposed in one of the second displacement yarn gaps 22 of the second yarn set 200 , and are interwoven with the individual first subset yarns 111 - 116 and the individual second subset yarns 121 - 126 , as illustrated in FIGS. 4A-4L . The first displacement yarns 230 and the second displacement yarns 240 move sinusoidally back and forth within the first displacement yarn gaps 21 and the second displacement yarn gaps 22 , respectively, in opposing sinusoidal patterns, such that each of the first displacement yarns 230 alternately contact the second displacement yarns 240 adjacent thereto along the length of the first displacement yarns 230 , and such that each of the second displacement yarns 240 alternatively contact the first displacement yarns 230 adjacent thereto along the length of the second displacement yarns 240 .

The overall appearance of the textile 10 is provided by the first and second displacement yarns 230 and 240 giving an alternating diamond shape pattern, and the first yarn groupings 210 and the second yarn groupings 220 , providing a leno type appearance through the center of the diamond shape patterns. By using a chenille yarn as the first and second displacement yarns 230 and 240 , as illustrated in FIGS. 1 and 2 , the textile 10 will have a bulkier and softer feel due to the radial fibers of the chenille yarns. Although the use of chenille yarns as the first and second displacement yarns 230 and 240 will provide the textile 10 with a softer feel, the interweaving of the first and second displacement yarns 230 and 240 with the individual first subset yarns 111 - 116 and the individual second subset yarns 121 - 126 , will allow the individual first subset yarns 111 - 116 and the individual second subset yarns 121 - 126 to provide the textile 10 with an improved abrasion resistance over typical textiles using chenille yarns.

The leno-type appearance created by the first grouping yarns 210 and the second grouping yarns 220 , can be enhanced by the use of a lower melt yarn for the individual first grouping yarns 211 - 213 and the individual second grouping yarns 221 - 223 , and then heat setting the textile 10 so that the individual first grouping yarns 211 - 213 bond together and the individual second grouping yarns 221 - 223 bond together. In one embodiment, the individual first grouping yarns 211 - 213 and/or the individual second grouping yarns 221 - 223 are a core/sheath yarn, where the sheath has a lower melting point than the core, and where the textile 10 is heat set so that the individual first grouping yarns 211 - 213 of each first subgrouping 210 bond together and that the individual second grouping yarns 221 - 223 of each second subgrouping 220 bond together

The pattern created by the first displacement yarns 230 and the second displacement yarns 240 can be stabilized by using lower melt yarns for some, or all, of the individual first subset yarns 111 - 116 and/or the individual second subset yarns 121 - 126 , and then heat setting the textile 10 so that these yarns bond with the first and second displacement yarns 230 and 240 . In one embodiment, the individual first subset yarns 111 - 116 and the individual second subset yarns 121 - 126 are a core/sheath yarn, where the sheath has a lower melting point than the core, and the textile 10 is heat set so that those yarns bond with the first and second displacement yarns 230 and 240 .

The individual first subset yarns 111 - 116 and the individual second subset yarns 121 - 126 of the first yarn set 100 can be an elastomeric yarn for suspension purposes, such as in a thin profile type seat. The individual first grouping yarns 211 - 213 and the individual second grouping yarns 221 - 223 of the second yarn set 200 can also be an elastomeric yarn for suspension purposes, such as in a thin profile type seat. The term elastomeric yarn, as used herein, means a nontextured yarn that can be stretched at room temperature to at least seventy-five percent over its original length and which after removal of the tensile force will immediately and forcibly return to within ten percent of its original length. To determine if a yarn is elastomeric, ASTM Standard Test Method for Permanent Deformation of Elastomeric Yarns (D 3106-95a), which is incorporated herein in its entirety by specific reference thereto, can be used with the exception that the specimen is stretched to a length of 75% over the original length of the specimen for all stretching time periods, and the elongation after stretch is determined after the longer relaxation time period.

In one embodiment, the individual first subset yarns 111 - 116 and the individual second subset yarns 121 - 126 are a 1000 denier monofiliment core/sheath elastomeric yarn, with the sheath being a lower melt temperature than the core, the individual first grouping yarns 211 - 213 and the individual second grouping yarns 221 - 223 are a 400 denier monofiliment elastomeric yarn, and the first and second displacement yarns 230 and 240 are a 3150 denier chenille yarn. In this embodiment, the individual first subset yarns 111 - 116 and the individual second subset yarns 121 - 126 in of the textile are evenly spaced apart warp yarns during the weaving process, and are at substantially the same tension. Also, the individual first grouping yarns 211 - 213 , the individual second grouping yarns 221 - 223 , and the first and second displacement yarns 230 and 240 are evenly spaced apart weft yarns during the weaving process, and are at substantially the same tension. However, after the weaving process, when tension is removed from the textile 10 , the individual first grouping yarns 211 - 213 come in contact together into the first yarn groups 210 , the individual second grouping yarns 221 - 223 come in contact together to form the second yarn groups 220 , and the first and second displacement yarns 230 and 240 move into the sinusoidal pattern illustrated in FIGS. 1 and 2 . After the textile 10 is relaxed, the textile 10 can be heated to melt the sheath of the core/sheath elastomeric yarns to bond the yarns.
