Definitions

• fabrics prepared from polyurethane elastic yarn having a cationic dyeable functionality and an acid dyeable yarn having a cationic dyeable functionality and an acid dyeable yarn.
• the fabrics can have a uniform color when prepared with separate dye systems.
• a fabric that contains elastane (a segmented polyurethane also referred to as spandex) has recognized benefits of comfort, fit, and shape retention. Additionally, it is obvious that consumers value fabrics with a professional looking appearance, which can include having a uniform color.
• One issue that the fabric industry has failed to address lies in combining the benefits of elastane with uniform color, specifically, the ability to dye the elastane to a shade of similar depth of a companion fiber such as polyamide (nylon). This issue increases with increasing elastane content in the fabric, and in knitted fabrics, including those that have been molded in an extended state. In both cases for knitted fabrics, the inherent stretch in the knitted construction allows for higher fabric stretch and higher yarn movement which exposes the spandex. In the trade the issue of elastane becoming visible in an undesirable manner in a section of fabric that has been stretched is commonly referred to as “grin through”.
• the inability to dye the elastane a common shade as the companion yarn, especially polyamide, is related to several factors that are common to shade matching any two chemically distinct fibers that dye with the same class of dyes.
• acid dyes are used to dye polyamide, silk, and wool, and yet they also are able to stain elastane, thus both fibers dye “together.”
• depth of shade is widely recognized to also be affected by yarn properties such as decitex, decitex-per-filament in a yarn bundle, and the thermal behavior of the fiber during dye processing conditions.
• an article including a fabric, where the fabric includes a cationic dyeable polyurethane elastic yarn and an acid dyeable yarn.
• the cationic dyeable yarn is selected from those disclosed in WO 2008/075605 to OPELONTEX CO., LTD of Japan., which is included herein by reference in its entirety.
• an article including a fabric, where the fabric has a uniform color.
• the fabric includes a cationic dyeable polyurethane elastic yarn, an acid dyeable yarn, a cationic dye, and an acid dye, wherein the acid dyeable yarn is selected from the group consisting of polyamide, proteinaceous, and combinations thereof.
• spandex As used herein, the terms spandex, elastane, and polyurethane elastic yarn are used interchangeably and refer to a segmented polyurethane elastic yarn.
• the cationic dyeable polyurethane elastic yarn and the acid dyeable companion yarn can be combined either in the same yarn, or in separately combined into the fabric.
• the fabric can be prepared into any suitable construction including circular knit, warp knit, and woven. After the fabric is prepared, the fabric is separately treated with cationic dyes and acid dyes. Either the cationic dye or the acid dye may be applied first depending on the desired properties of the fabric.
• the cationic dyeable elastane may be used in a fabric in any suitable amount to provide the desired stretch-recovery property to the fabric.
• the fabric may include greater than zero and up to about 60 % by weight of the cationic dyeable elastane.
• Another suitable method for obtaining a uniformly colored fabric is to prepare a knitted or woven fabric with the cationic dyeable elastane and an acid dyeable companion yarn.
• the fabric is first contacted with an acid dye to the achieve the desired shade for the companion yarn using dyes that either do not dye at all or only slightly dye or stain the cationic dyeable elastane.
• the fabric is contacted with a cationic dye to dye the elastane.
• Dyeing of the elastane yarn of the fabric may occur in a separate step or in the same dye bath where the acid dyeable companion yarn is dyed.
• the acid dye bath is combined with an alternative dye recipe (such cationic dyes) that have been specifically adjusted for the elastane's unique chemistry and fiber diameter to match the shade of the companion yarn.
• the elastane color depth can be optimized to match the companion yarn in the relaxed state in a fabric or at a specifically targeted level of extension.
• the companion yarn may include any acid dyeable yarn.
• fibers that are dyeable with acid dyes include polyamides and proteinaceous fibers.
• Polyamide polymers are well known in the art. They are generally prepared by the condensation polymerization of a dicarboxylic acid and a diamine or the condensation of a monoaminomonocarboxylic acid which is normally derived from its internal lactam. Examples of such polyamides are nylon 6,6 or nylon-6 which are respectively prepared from hexamethylene diamine—adipic acid mixtures and ⁇ -caprolactam. Examples of other fiber-forming polyamides are nylon-6/6,6 copolymers, nylon-11, nylon-12. Examples of proteinaceous fibers include silk, wool, mohair, angora, and alpaca. Combinations of these fibers may be used in the same yarn or single component yarns may be combined into fabric.
• Examples of useful acid dyes include Color Index (C.I.) dyes: Acid Yellows 24, 40, 59, 159, 184, 204 and 246, Acid Oranges 142 and 156, Acid Reds 50, 51, 52, 138, 151, 299, 361, 362, Acid Greens 104 and 108, Acid Blues 113, 171, 185, 193, 277 and 324, Acid Violet 90, Acid Brown 298, Acid Blacks 52, 131:1, 132:1, 172, 187 and 194.

• Color measurements are made on fabrics with a Datacolor Spectraflash Model SF-300 colorimeter (Datacolor International, Lawrenceville, N.J.) using a D65/10 degree illuminant. Measurements are reported using the international standard color measurement method promulgated by “Commission Internationale de L'Eclairage” (Paris, France), (International Society for Illumination/Lighting), (“CIE”) using standard color coordinates of the CIELAB L*a*b* color space: “L” designates the lightness coordinate; “a” designates the red/green coordinate (+a indicating red and ⁇ a indicating green); and “b” designates the yellow/blue coordinate (+b indicating yellow and ⁇ b indicating blue).
• CIE Commission Internationale de L'Eclairage
• the total color difference between two samples, ⁇ E is obtained by taking the difference between the L*, a*, and b* coordinates.
• the uniform color of the fabrics include where color of the fabric as measured by a-color, b-color, and L-value is within 10% of the values that are obtained by removing the cationic dyeable elastic yarn from the fabric.
• Hose or garment pre-steamed at autoclave temperatures ranging from 85-115 C can be used to stabilise garment sizing and to minimise creasing in subsequent wet processing.
• Open Width Fabric Stabilisation particularly for LYCRA® fibre blends can be achieved in dry heat stenter setting at 160-200 C for 60-45 seconds, Depending on fabric quality an Anti-oxidant protection may be used in the pad to protect the amine end groups/dye sites of the polyamide during pre-setting (commercial example 2-3% owf Spanscour Spark Tanatex)
• Cationic dyes strike faster than anionic dyes and should be applied to the dye bath first at the lowest possible temperature, with a cationic levelling agent.
• subsequent treatment at 40-70 C for 10-30 minutes will achieve substantial exhaustion>Application of the acid dyes, after cooling back to 40 C, can then be more safely managed raise at 1 c/ minute to 98 c dye 30-60 minutes.
• pH6.5-7.0 will be optimum but sometimes downward adjustment to pH4.5-5.5 will be required to achieve dye exhaustion. It is important to set the pH before the addition of the cationic dyes to avoid rapid strike on to the spandex from residual scour alkali
• Glaubers salt retards cationic dyes on spandex and also improves levelling.
