Yarn formed from recycled cotton and recycled para-aramid, and fabrics made therefrom

Abstract

Described herein are spun yarns, core spun yarns, and fabrics such as denim fabrics made thereof that contain recycled cotton fibers and recycled para-aramid fibers. The combination of fibers in the yarns and fabrics provide desirable properties such as increased tear strength, breaking strength, and abrasion resistance compared to yarns and fabrics made of 100 wt % cotton.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims benefit of U.S. Provisional Application No. 62 / 598,867, filed on Dec. 14, 2017, the disclosure in its entirety is herein incorporated by reference.BACKGROUND OF THE INVENTION[0002]The typical life cycle of denim begins with the extraction of raw materials and ends with disposal of the denim. However, the life cycle can be maintained as an ongoing circle by way of recycling of materials and components and producing sustainable products from the recycled materials. Such a closed-loop production cycle is advantageous in creating a sustainable textile industry.[0003]Life Cycle Assessment (LCA) studies have been performed to analyze the potential environmental impact of a product such as a cotton textile from raw material extraction to endproduct disposal. This systems-based, quantitative method has been used to evaluate the environmental impact of the different life stages for a pair of denim jeans including the stages ...

AI Technical Summary

Benefits of technology

The patent describes a spun yarn and a core spun yarn that use recycled para-aramid fiber, recycled cotton fiber, and virgin cotton fiber to create a strong yarn with a similar tensile strength to yarns made from cotton. The recycled fiber can be from various sources such as recycled para-aramid fiber, recycled cotton fiber, and virgin cotton fiber. The yarns can be used to create denim fabric and other textile products. The technical effect of this invention is the creation of a strong yarn that uses recycled materials to reduce waste and environmental impact.

Problems solved by technology

For example, the agriculture processes associated with growing cotton, and the manufacturing of cotton fibers are harmful to the environment because these processes utilize large quantities of water, herbicides, fertilizers and pesticides, which are required for growing the cotton.

Both the growing of cotton and the manufacture of cotton fibers contribute to harmful pollutants to air and water, and use significant amounts of energy and other non-renewable resources.

Unfortunately, staple cotton fibers produced from recycled cotton fabric are shorter in length compared to staple fiber from virgin cotton, thereby, compromising the strength and softness of the yarns and fabrics made thereof.
