Description

TECHNICAL FIELDS

The present disclosure pertains generally to the field of textile industry. More specifically, the present disclosure pertains to a woven textile fabric with higher thread count that exhibits low pilling tendency, while being economical.

BACKGROUND

Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
Often in textile manufacturing, it becomes necessary to scrap products for one reason or another. For example, it could be that the products, once manufactured, did not meet the desired specifications, or perhaps, the product was not as marketable as anticipated. Further textiles used by the consumer are thrown into the landfills have become a big global problem. Apparel made from natural fibers takes years to decompose, whereas man-made fibers do not self-decompose. Woolen clothes do decompose but release methane and carbon dioxide into the atmosphere. This contributes towards global warming. Synthetic fabrics in the landfill release nitrous oxide which is a powerful greenhouse gas. Besides, toxic substances pollute groundwater and surrounding soil.
With increasing demand and problems associated with the decomposition of Apparel, recycling and reusing textiles, fibers, and waste materials is an effective way to build sustainability in the apparel industry. Numerous recycled textile fabrics are reported in the literature, and available in markets that are used by retailers and consumers. However, these recycled textile fabrics are of low quality, non-durable, and exhibit poor elasticity, chemical resistance, tensile strength, pilling, and the like.
There is, therefore, a need in the art to provide a new and improved textile fabric that is comfortable, breathable, wrinkle resistant, exhibits high strength, low piling, and the like, that can find utility as a home textile. The present disclosure satisfies the existing needs, as well as others, and alleviates the shortcomings associated with conventional recycled fabrics.
Groupings of alternative elements or embodiments of the invention disclosed herein are not to be construed as limitations. Each group member can be referred to and claimed individually or in any combination with other members of the group or other elements found herein. One or more members of a group can be included in, or deleted from, a group for reasons of convenience and/or patentability.

OBJECTS

An object of the present disclosure is to provide a woven textile fabric that overcomes the deficiencies associated with the conventional woven textile fabric.
Another object of the present disclosure is to provide a woven textile fabric that has high thread count.

DETAILED DESCRIPTION

The following is a detailed description of embodiments of the disclosure depicted in the accompanying drawings. The embodiments are in such detail as to clearly communicate the disclosure. However, the amount of detail offered is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within scope of the present disclosure.
Each of the appended claims defines a separate invention, which for infringement purposes is recognized as including equivalents to the various elements or limitations specified in the claims. Depending on the context, all references below to the “invention” may in some cases refer to certain specific embodiments only. In other cases it will be recognized that references to the “invention” will refer to subject matter recited in one or more, but not necessarily all, of the claims.
Unless the context requires otherwise, throughout the specification which follows, the word “comprise” and variations thereof, such as, “comprises” and “comprising” are to be construed in an open, inclusive sense that is as “including, but not limited to.”
Reference throughout this specification to “one embodiment” or “an embodiment” means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
As used in the description herein and throughout the claims that follow, the meaning of “a,” “an,” and “the” includes plural reference unless the context clearly dictates otherwise. Also, as used in the description herein, the meaning of “in” includes “in” and “on” unless the context clearly dictates otherwise.
All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g. “such as”) provided with respect to certain embodiments herein is intended merely to better illuminate the invention and does not pose a limitation on the scope of the invention otherwise claimed. No language in the specification should be construed as indicating any non-claimed element essential to the practice of the invention.
The expression “rating of 3 or above” as used herein throughout the present disclosure, in the context of the fabric tested for pilling after 1000 rubs, generally denotes low pilling tendency of the fabric being tested. Particularly, when the pilling tendency of the finished fabric is measured by any of the standard methods such as ASTM D4970 or ISO 12945-2:2014 and rated on a scale/grade/rating of 1-5, the scale/rating/grade 1 indicating very severe pilling and scale/rating/grade 5 indicating no pilling after the specified number of rubs (e.g. after 1000 rubs or cycles), the fabric exhibits a rating of 3 or 4 or 5, i.e. the woven textile fabric has low pilling tendency.
The term “woven textile fabric”, as used herein throughout the present disclosure in the context of the fabric being tested for pilling tendency or pilling resistance denotes a dyed, bleached or a printed fabric, or otherwise a fabric that is substantially ready for use (e.g. consumer use) without need to be subjected to any further processing that can alter its pilling tendency or pilling resistance. For example, the raw woven fabric may be subjected to dying and/or printing and/or bleaching process(es) to produce the fabric. Such fabric is then subjected to the test for measurement of pilling resistance or pilling tendency.
In some embodiments, the numbers expressing quantities of ingredients, properties such as concentration, and so forth, used to describe and claim certain embodiments of the invention are to be understood as being modified in some instances by the term “about.” Accordingly, in some embodiments, the numerical parameters set forth in the written description are approximations that can vary depending upon the desired properties sought to be obtained by a particular embodiment. In some embodiments, the numerical parameters should be construed in light of the number of reported significant digits and by applying ordinary rounding techniques. Notwithstanding that the numerical ranges and parameters setting forth the broad scope of some embodiments of the invention are approximations, the numerical values set forth in the specific examples are reported as precisely as practicable.
The recitation of ranges of values herein is merely intended to serve as a shorthand method of referring individually to each separate value falling within the range. Unless otherwise indicated herein, each individual value is incorporated into the specification as if it were individually recited herein.
The headings and abstract of the invention provided herein are for convenience only and do not interpret the scope or meaning of the embodiments.
Various terms as used herein are shown below. To the extent a term used in a claim is not defined below, it should be given the broadest definition persons in the pertinent art have given that term as reflected in printed publications and issued patents at the time of filing.

Although each embodiment represents a single combination of inventive elements, the inventive subject matter is considered to include all possible combinations of the disclosed elements. Thus if one embodiment comprises elements A, B, and C, and a second embodiment comprises elements B and D, then the inventive subject matter is also considered to include other remaining combinations of A, B, C, or D, even if not explicitly disclosed.
