Abstract:
1. A process for using recycled waste cotton material to produce a ring spun yarn, the process comprising: collecting different categories of waste cotton material from a variety of textile formation processes; determining parameters of each process used in making the ring spun yarn to be produced to determine characteristics for each yarn used in the ring spun yarn to be produced; assessing a fiber length and strength of the fibers from the waste cotton material categories collected; selecting specific categories of waste cotton material to be blended together depending on the ring spun yarn to be produced, the characteristics for each yarn used in the ring spun yarn to be produced, and the length and strength of the fibers from the waste cotton material categories; selecting a sequence of cleaning, opening and blending processing steps used in making a yarn depending on the ring spun yarn to be produced; cleaning the selected specific categories of waste cotton material; opening and blending the selected specific categories of waste cotton material into blended waste cotton fibers; and processing the blended waste cotton fibers into the ring spun yarn to be produced, wherein the ring spun yarn produced has a cotton count of greater than about 15/1 and up to about 32/1, wherein 100% of material used in making the ring spun yarn comprises waste cotton material, wherein waste material used in making the ring spun yarn comprises:
