The aramid paper consists essentially of a nonwoven, nonfused commingled mixture of floc of a nonfusable aromatic polyamide and fibrids of a nonfusable aromatic polyamide and is sufficiently dye and abrasion resistant so that the indicia are readable after the tag is exposed to harsh dyes, bleaches, high temperatures, and pressures. The tag may be affixed by sewing or clipping or may include a pressure sensitive surface. Multiple plies may be laminated in cross directions to increase tear strength. ## Claims ### Claim 1 A method of identifying textile units subject to a chemical treatment process including dyeing of the unit comprising: (a) applying color-contrast indicia directly onto an aramid paper layer of an abrasion and dye resistant tag, (b) attaching the tag to a textile unit, the (c) subjecting said textile unit with said tag attached to the chemical treatment process for dyeing and treating said unit, said color-contrast indicia remaining visible after completion of said process and wherein said aramid paper layer consists essentially of a nonwoven, nonfused commingled mixture of floc of a nonfusable aromatic polyamide and fibrids of a nonfusable aromatic polyamide. ### Claim 2 (depends on 1) The method of claim 1 wherein at least some of said color-contrast indicia are applied in a machine-readable arrangement. ### Claim 3 (depends on 1) The method of claim 1 wherein said paper is a calendered paper. ### Claim 4 (depends on 3) The method of claim 3 wherein said color-contrast indicia is ink applied to an uncoated surface of said aramid paper layer, and said uncoated surface is exposed to the chemical treatment process. ### Claim 5 (depends on 4) The method of claim 4 wherein said paper has a density of at least 0.6 gm/cm.sup.3 or greater. ### Claim 6 (depends on 4) The method of claim 4 wherein said paper has a thickness between 2 mils and 15 mils. ### Claim 7 (depends on 1) The method of claim 1 wherein said color-contrast indicia includes information on a characteristic of said textile unit and/or the textile process to which the unit is subjected. ### Claim 8 An article comprising a textile unit, a destruction resistant and dye-resistant tag attached to said textile unit, said tag comprising at least one ply of aramid paper and having color-contrast indicia directly on said at least one ply of aramid paper, and wherein said at least one ply of aramid paper consists essentially of a nonwoven, nonfused commingled mixture of floc of a nonfusable aromatic polyamide and fibrids of a nonfusable aromatic polyamide. ### Claim 9 (depends on 8) The article of claim 8 wherein at least some of said color-contrast indicia are in machine-readable form. ### Claim 10 (depends on 8) The article of claim 8 wherein said aramid paper is a calendered paper. ### Claim 11 (depends on 10) The article of claim 10 wherein said color-contrast indicia is ink applied to an uncoated surface of said aramid paper layer, and said tag is sufficiently dye resistant that said ink remains legible even after said uncoated surface is exposed to the chemical treatment process. ### Claim 12 (depends on 11) The article of claim 11 wherein said aramid paper has a density of at least 0.8 gm/cm.sup.3. ### Claim 13 (depends on 11) The article of claim 11 wherein said aramid paper has a thickness between 2 mils and 15 mils. ### Claim 14 (depends on 8) The article of claim 8 wherein said color-contrast indicia includes information on a characteristic of said textile unit and/or a chemical process to which the unit is subjected. ### Claim 15 (depends on 8) The article of claim 8 wherein said aramid paper has a Finch tear characteristic greater than 100 for its machine direction (MD) and 60 for its cross direction (XD). ### Claim 16 (depends on 8) The article of claim 8 wherein the Finch Tear characteristic of the aramid paper is at least 300 in the MD direction and at least 180 in the XD direction. ### Claim 17 (depends on 16) The article of claim 16 wherein the thickness of the ply is between 2 mils and 15 mils. ### Claim 18 (depends on 17) The article of claim 17 wherein the density of the aramid paper is at least 0.6 gm/cm.sup.3. ### Claim 19 (depends on 8) The article of claim 8 wherein the tag comprises at least two layers forming a laminated tag, each layer comprising a ply of aramid paper. ### Claim 20 (depends on 19) The article of claim 19 wherein the layers are arranged with their MD perpendicular to each other. ### Claim 21 (depends on 8) The article of claim 8 wherein one side of the paper includes a pressure sensitive adhesive. ### Claim 22 A tag for identification of articles subject to a chemical process including dyeing and/or finishing of the article comprising at least one ply of aramid paper, said paper having color-contrast indicia directly thereon identifying a characteristic of the article and/or the process to which the article is subject, said paper being sufficiently dye resistant and abrasion resistant so that the indicia remains legible after completion of the process, and wherein said at least one ply of aramid paper consists essentially of a nonwoven, nonfused commingled mixture of floc of a nonfusable aromatic polyamide and fibrids of a nonfusable aromatic polyamide. ### Claim 23 (depends on 22) A tag as set forth in claim 22 having one surface including a pressure sensitive adhesive. ### Claim 24 (depends on 22) A tag as set forth in claim 22 including at least two plys of aramid paper laminated together, the indicia being on at least one exposed surface of the lamination. ### Claim 25 (depends on 24) A tag as set forth in claim 24 wherein each said plys have a tensile strength greater in the machine direction (MD) than in the cross direction (XD), the plys being laminated with the machine direction (MD) of one ply being perpendicular to the machine direction (MD) of the other ply. ### Claim 26 (depends on 22) A tag as set forth in claim 22 wherein said ply has a density of at least 0.8 gm/cm.sup.3. ### Claim 27 (depends on 22) The tag as set forth in claim 22 wherein the thickness of the ply is between 2 mils and 15 mils. ### Claim 28 (depends on 22) The tag as set forth in claim 22 wherein the ply has a Finch tear characteristic greater than 100 in its machine direction (MD) and greater than 60 in its cross direction (XD). ### Claim 29 (depends on 28) The tag as set forth in claim 28 wherein the Finch tear characteristic is at least 300 in the MD direction and at least 180 in the XD direction.
