The present disclosure pertains generally to the field of textile industry. In particular, the present disclosure provides a textile fabric that can find utility as home textile.
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, exhibits high strength, low piling, and the likes 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.
An object of the present disclosure is to provide a textile fabric that overcomes the deficiencies associated with the conventional woven textile fabric.
Another object of the present disclosure is to provide a textile fabric that exhibits high tensile strength and good piling resistance.
Another object of the present disclosure is to provide a textile fabric that is durable, wrinkle resistant, and comfortable to human skin.
Another object of the present disclosure is to provide a textile fabric that is economical and easy to manufacture.
