[0003] priority

[0004] This application claims the benefit and priority of U.S. Patent Application No. 15 / 633,535, filed June 26, 2017, and U.S. Provisional Application No. 62 / 416,092, filed November 1, 2016, entitled “Material Blend With Patterned Weave”. Technical Field

[0005] The scope of this disclosure generally relates to dyed woven and / or knitted fabrics. More specifically, the scope of the invention relates to an apparatus and method for a cotton / polyester blend fabric comprising a dye having a strong affinity for the cotton and a relatively weak affinity for the polyester, to provide the cotton / polyester blend fabric with unique colors and patterns that increase creative options for fashion designers. Background Technology

[0006] Blends of cotton and polyester fibers are important textiles used in the manufacture of clothing and other textile products. It is well known that the dyes and processing conditions used for coloring cotton differ from those used for coloring polyester fibers.

[0007] Cotton fibers can be dyed with fiber reactive dyes of the vinyl sulfone, dichloroquinoxalone, halotriazine, and halopyrimidine types. These dyes can be applied to the fibers under alkaline conditions in an aqueous solution containing an electrolyte at a temperature ranging from approximately 40°C to 110°C, the electrolyte facilitating the expulsion of the dye from the dye bath into the fibers. These dyes form covalent bonds with the hydroxyl groups of cotton and exhibit excellent fastness properties. These fiber reactive dyes are also hydrophilic, have a high affinity for cellulosic cotton fibers, and are stable under alkaline pH conditions.

[0008] Polyester fibers are hydrophobic and can typically be dyed with disperse dyes, which are also hydrophobic. These disperse dyes are slightly soluble in water and are typically dispersed in water using a dispersant, usually a surfactant in combination with other auxiliaries. The disperse dyes color the polyester fibers by diffusing into the fibers under the influence of heat and dyeing auxiliaries. Unfortunately, disperse dyes are generally unstable at higher pH levels and are typically applied at temperatures of 120°C–140°C at pH 5–7. Additionally, disperse dye dispersions can be sensitive to electrolytes, which can lead to dispersion instability.

[0009] However, as will be appreciated, the polyester fibers constituting the cotton / polyester blend can have a slight affinity for fiber reactive dyes applied to the cotton, thereby producing a wide variety of resulting color mixtures or patterns on the cotton / polyester blend, whereby the reactive dyes can have a very low affinity for the polyester, thus forming unique patterns through the dyes and the fiber blended yarns. Summary of the Invention

[0010] An apparatus and method are provided for a blended fabric with a desired patterned color. In one embodiment, the blended fabric comprises a first portion made of cotton and a second portion made of polyester.

[0020] The accompanying drawings relate to embodiments of this disclosure, wherein:

[0021] Figure 1 Exemplary embodiments of knitted fabrics made of cotton / polyester blends dyed according to this disclosure are shown.

[0022] While this disclosure is subject to various modifications and alternatives, specific embodiments thereof have been illustrated by way of example in the accompanying drawings and will be described in detail herein. It should be understood that the invention is not limited to the specific forms disclosed, but rather encompasses all modifications, equivalents, and alternatives falling within the spirit and scope of this disclosure. Detailed Implementation

[0023] In the following description, numerous specific details are set forth in order to provide a thorough understanding of this disclosure. However, it will be apparent to those skilled in the art that the invention disclosed herein can be practiced without these specific details. In other instances, specific numerical references may be made, such as “first material.” However, specific numerical references should not be construed as literal order, but rather as meaning that “first material” is distinct from “second material.” Therefore, the specific details set forth are merely exemplary. These specific details may vary within the spirit and scope of this disclosure and are still contemplated within its spirit and scope. The term “coupled” is defined as meaning a direct connection to a component or an indirect connection to said component via another component. Furthermore, as used herein, for any numerical value or range, the terms “about,” “approximately,” or “substantially” indicate suitable dimensional tolerances that allow a portion or collection of components to function as intended for the purposes described herein.

[0024] In general, the present invention provides a blended fabric with a desired patterned color. The blended fabric comprises a first portion of cotton and a second portion of polyester. A dye having a strong affinity for cotton and a relatively weak affinity for polyester can be applied to the blended fabric. The dye imparts a deep black color to the cotton portion and a light gray color to the polyester portion of the fabric. The combination of deep black cotton and light gray polyester provides the patterned color to the blended fabric. The blended fabric may consist of a larger percentage of cotton than polyester, the cotton and polyester being spun into monofilament yarns, which are then knitted into any one of looped terry, plain knit, or napped fabrics. Insufficient dye absorption in the cotton and polyester produces both deep and light patterns within the blended fabric.

[0025] Figure 1 Exemplary embodiments of cotton / polyester blended fabrics dyed according to this disclosure are shown. In some embodiments, the blended fabric may be a plain knit pattern fabric, such as... Figure 1As shown, its weight ranges from approximately 3 oz / yard² to approximately 12 oz / yard². Generally, the weight of the blended fabric is a function of the yarn size, which can range from 16-single to 50-single. In some embodiments, the blended fabric can be composed of any of a variety of weave or knit pattern; for example, in some embodiments, the blended fabric can be a looped knitted terry fabric or a napped fabric. In some embodiments where the blended fabric includes a napped fabric, two different sizes of yarn can be blended together to achieve various desired weights of the blended fabric. In some embodiments, the blended fabric is preferably composed of a blended yarn spun from cotton and polyester, consisting of approximately 10% polyester and approximately 90% cotton. However, it is contemplated that the spun blended yarn can be composed of any of, but is not limited to, other natural and synthetic fibers or blends thereof, as well as a wide variety of textured synthetic multifilament yarns.

[0026] In some embodiments, the yarn may first be washed in a continuous washing solution at a temperature ranging from about 180°F to about 210°F, and then rinsed or washed in a series of hot and cold water baths to remove any natural oils, waxes, and any additives from earlier opening, blending, carding, or spinning operations. The yarn is then dried before being introduced into the dye bath so that the moisture percentage is again equal to or below normal, for example, by a non-limiting example, from about 2% to about 5% for polyester / cotton blended yarns. As will be appreciated, the dryness of the yarn helps to draw the dye into the yarn. Furthermore, maintaining the dye bath at a temperature ranging from about 130°F to about 190°F allows the dye to substantially penetrate the yarn or fiber bundle.

[0027] When dyeing polyester / cotton blended yarns, as referred to in this article Figure 1 Both the polyester and cotton portions can be infiltrated and dyed. Typically, the dye has a strong affinity for the cotton and a relatively weak affinity for the polyester. Although the polyester portion can be slightly infiltrated by the dye, the resulting shade of the polyester portion will be much lighter than that of the cotton portion. In one embodiment, the dye imparts a deep black to the cotton portion of the yarn and a light gray to the polyester portion. The combination of the deep black cotton and the light gray polyester provides unique colors and patterns to the cotton / polyester blended fabric, such as... Figure 1 As shown.

[0028] In some embodiments, a light-dark pattern can be applied to a blended fabric in the form of any loop-knitted terry fabric, plain knitted fabric, or napped fabric. The blended fabric is generally composed of a first material and a second material, which can be spun into monofilament yarns. In some embodiments, the first material may be cotton, and the second material may be polyester. The first and second materials can be spun to form monofilament yarns comprising substantially 90% cotton and substantially 10% polyester. The monofilament yarns can then be knitted into fabrics, such as loop-knitted terry fabrics, plain knitted pattern fabrics, or napped fabrics. A black reactive dye can be applied to the fabric to apply the light-dark pattern. It will be appreciated that the black reactive dye is well absorbed by the cotton and relatively poorly absorbed by the polyester. The insufficient dye absorption of the polyester and the strong dye affinity of the cotton work together to give the blended fabric the desired light-dark pattern.

[0029] In one exemplary method, a light-dark pattern can be applied to a blended plain knit fabric. The blended plain knit fabric may be composed of knitted monofilament yarns. These monofilament yarns are formed by spinning cotton and polyester, such that the monofilament yarns consist of substantially 90% cotton and substantially 10% polyester. A black reactive dye can be applied to the blended plain knit fabric. The black reactive dye is allowed to be absorbed by the cotton and substantially not by the polyester, working together to impart the light-dark pattern to the blended plain knit fabric.

[0030] Although the invention has been described with reference to specific variations and illustrative drawings, those skilled in the art will recognize that the invention is not limited to the described variations or drawings. Furthermore, where the methods and steps described above indicate that certain events are performed in a specific order, those skilled in the art will recognize that the order of certain steps can be modified, and such modifications are consistent with variations of the invention. Additionally, certain steps may be performed simultaneously in parallel processes where possible, or they may be performed sequentially as described above. This patent is intended to also cover variations of the invention that exist within the spirit of this disclosure or are equivalent to those found in the claims. Therefore, this disclosure should be understood not to be limited to the specific embodiments described herein, but only to the scope of the appended claims.
