Patent number: 5519925Abstract: Denim fabric suitable for use as apparel is made from about 40-100% fibers produced from denim waste (pre-consumer and/or post-consumer). The denim waste is collected, starch and size are optionally removed, and it is subjected to garnetting to produce denim fibers, the vast majority of fiber lengths greater than about 0.4 inches, and an average length greater than 0.5 inches. The denim fibers are then opened, and subjected to low-tension carding, as by using a Rieter C-4 type card with conveyor belt. The carded denim fibers are spun into filling yarn having a yarn count between about 4.0/1 to 16.0/1, and/or a warp or knitting yarn having a yarn count between about 4.0/1 to 16.0/1. The warp or knitting yarn may be plied with like reclaimed warp yarn, or with virgin fiber warp yarn.Type: GrantFiled: May 10, 1995Date of Patent: May 28, 1996Assignee: Burlington Industries, Inc.Inventors: Darlene L. Ball, Max H. Hance

Patent number: 5419952Abstract: Denim fabric is made from warp yarn which is at least 30% novelty cotton yarn having irregularly spaced effects (e.g. slubs) about one-half inch to two inches in length. The cotton novelty yarn is made by separating cotton sliver into cotton fibers, and acting on the cotton fibers with a negative wire combing roll, and then twisting the cotton fibers into the cotton novelty yarn. The negative wire combing roll has a tooth angle of about -0.01 to -15.degree. (e.g. about -2.degree.). The novelty cotton yarn is combined with at least 10% conventional novelty yarn or non-slub open end or ring spun yarn and made into a warp of about 54-100 ends per inch, and may be ring dyed (with indigo, vat, sulphur, pigment or reactive dye) so that the core of the yarn remains white. The warp is woven with a filling yarn to produce a denim fabric with a weight of about 5 oz. -17 oz. per sq. yd. having the weave and yarn size selected so that a tight construction is provided which highlights the slubs.Type: GrantFiled: May 26, 1993Date of Patent: May 30, 1995Assignee: Burlington Industries, Inc.Inventors: Michael W. Brown, Lee K. Powell, James C. Slagle, Jr., Ben M. Croker, Max H. Hance

Patent number: 5407447Abstract: A method for producing a dyed cotton fabric having an improved characteristic salt-and-pepper look and the product thereof. The process includes forming a plurality of individual cotton yarns having a twist multiple value of at least 4.6 and, preferably, subjecting the twisted cotton yarn to exposure to a caustic solution under tension. The yarn then is dyed under tension by exposure to a dye liquor. The treated yarn is used to produce a woven fabric, which after being abraded, has a lighter portion dispersed throughout a darker portion. In the preferred embodiment the twist multiple value of the cotton yarn threads varies within the range of between 4.6 and 10.5.Type: GrantFiled: February 3, 1993Date of Patent: April 18, 1995Assignee: Burlington IndustriesInventors: Edward W. Teague, Jarvis L. Clark, Max H. Hance
