Yarn manufactured from recycled clothing fibers and process for making same
Yarn manufactured from recycled mixed clothing fibers and a process of making yarn manufactured from recycled mixed clothing fibers. Upcycled yarn has approximately 70%-95% of fiber from separated used clothes fibers, whereby separated used clothes fibers have cotton, polyester, nylon, silk, rayon, spandex, synthetic fibers, wool, hemp, carbon fibers, and/or linen. The upcycled yarn also has approximately 5%-30% other fibers that can be recycled fibers and/or virgin fibers, whereby the recycled fiber is recycled polyester from recycled plastic bottles and other sources, recycled cotton, recycled nylon from fishing nets and other sources, and the virgin fiber is nylon, spandex, virgin polyester, hemp, carbon fiber, and/or organic cotton.
Heat Treated Multilayer Knitted Textile of Liquid Crystal Polymer Fibers and Modified Polyacrylonitrile Fibers, and Process for Making Same
The invention relates to a process for manufacturing a multilayer knitted textile by heating a multi-layer knitted textile in the presence of one or more dye compounds, wherein the multilayer knitted textile comprises a fabric outer layer and a fabric inner layer, wherein the fabric outer layer is knit from a first yarn containing a combination of modacrylic fibers and cotton fibers, wherein the fabric inner layer is knit from a second yarn made from 50-90% HBA/HNA filaments, wherein the heating shrinks the outer layer from about 5 to 25% in length, width, or both.
MACHINE-KNITTABLE CONDUCTIVE HYBRID YARNS
A machine knittable hybrid yarn for providing conductive traces through a textile is disclosed. The hybrid yarn includes conductive wires coated with an insulating material and twisted together with a nonconductive yarn. The nonconductive yarn is from a strong, inelastic, and nonconductive fiber, such as a meta-aramid or para-aramid that protects the integrity of the conductive wire during knitting. The conductive wire can be copper-clad stainless steel or copper wire is coated with polyurethane, and the nonconductive yarn can have no-drip and no-drip properties to allow ablation of the hybrid yarn to remove the conductive yarn and insulating coating on the wire such that the ablated region becomes externally conductive and suitable for making an electrical contact. The hybrid yarn can be bonded with nylon or similar polymer after twisting.
Textile Materials Containing Yarns with an Intimate Blend of Aramid Fibers and Polyphenylene Sulfide Fibers
The invention provides a woven textile having a first and second side and comprising a plurality of yarns, wherein at least a portion of the yarns comprise an intimate blend of at least about 51% by weight polyphenylene sulfide fibers, less than about 49% by weight para-aramid fibers, and, less than about 2% by weight meta-aramid fibers. The polyphenylene sulfide, para-aramid, and meta-aramid fibers are staple fibers with an average staple fiber length of between about 20 and 100 mm.
ANTIVIRAL ARTICLES
Provided is a textile made of filament yarn comprising a polymer composition that is durable and reusable having permanent or near-permanent antiviral properties and that includes a polymer, a metal ion, preferably a zinc and/or copper ion, and an optional phosphorus compound, wherein fibers and/or fabric formed from the polymer composition demonstrate antiviral properties and wherein the polymer is hygroscopic. The present disclosure also describes methods of forming the polymer compositions and methods of preparing fibers from the polymer composition.
ANTIMICROBIAL/ANTIVIRAL PLASTICS AND MOLDED PRODUCTS
A polymer composition for molded products having antimicrobial and/or antiviral properties comprising from 50 wt. % to 99.9 wt. % of a polymer, from 0.01 wt % to 10 wt % zinc, optionally from a zinc compound, less than 1 wt % of a phosphorus compound, and from 0 wt % to 20 wt % molding additives, wherein a molded product formed from the polymer composition demonstrates a Staphylococcus aureus log reduction greater than 1.0, as determined via ISO 22196:2011.
ANTIVIRAL/ANTIMICROBIAL POLYMER COMPOSITIONS, FIBERS, AND PRODUCTS
A polymer composition having antimicrobial properties, the composition comprising from 50 wt % to 99.99 wt % of a polymer, from 10 wppm to 900 wppm of zinc, less than 1000 wppm of phosphorus, and less than 10 wppm coupling agent and/or surfactant, wherein zinc is dispersed within the polymer; and wherein fibers formed from the polymer composition demonstrate a Klebsiella pneumonia log reduction greater than 0.90, as determined via ISO20743:2013 and/or an Escherichia coli log reduction greater than 1.5, as determined via ASTM E3160 (2018).
Carbon-containing aramid bicomponent filament yarns
A yarn comprising a plurality of bicomponent filaments having a first region comprising a first polymer composition and a second region comprising a second polymer composition; the regions being distinct and present in the bicomponent filaments in a sheath-core structure or a side-by-side structure; wherein the first polymer composition comprises aramid polymer containing 0.5 to 20 weight percent homogeneously dispersed discrete carbon particles and the second polymer composition comprises aramid polymer being free of discrete carbon particles and having at least one homogeneously dispersed masking pigment, the yarn having a total content of 0.5 to 5 weight percent discrete carbon particles.
Hybrid twisted cord
A hybrid fiber cord includes a first yarn and a second yarn. The first yarn has a first ply length, a first twist number, and a first elongation at break. The second yarn has a second length greater than the first length, a second twist number, and a second elongation at break that is less than the first elongation at break. The first yarn and the second yarn have the same cord twist. The hybrid fiber cord has a third elongation at break that is greater than the second elongation at break.
Flame resistant fabrics having fibers containing energy absorbing and/or reflecting additives
Embodiments of the invention relate to flame resistant fabrics containing fibers having at least one energy absorbing and/or reflecting additive incorporated into the fibers. Inclusion of such fibers into the fabric increases the arc rating/fabric weight ratio of the fabric while still complying with all requisite thermal protective requirements.
