A welding process may be configured to convert a substrate comprised of short staple fibers into a welded substrate having significantly increased strength as compared to the raw substrate. When applied to a one-dimensional substrate, such as a yarn, the welding process may also reduce the diameter of the welded substrate compared to that of the raw substrate. Additionally, the welding process may be configured to impart superior color properties to the welded substrate compared to the color properties of the raw substrate, which superior color properties may be very pronounced when performing a welding process on a raw substrate comprised of colored and/or dyed recycled fibers.

A method 100 for processing fibrous matter from a waste material involves obtaining 101 the waste material, trimming 102 the waste material, pre-treating 104, second mechanical treatment 106, washing 108, first chemical treatment 110 with an enzyme and water solution, draining 112 the enzyme and water solution, heating 114 to obtain a fiber cake, providing 116 controlled shockwaves, a second chemical treatment 118, hydro-extracting 120 fiber cake, opening 122 the fiber cake, drying 124, pre-conditioning and softening 126, mechanically treating and segregating 128, softening 129, processing 130 to obtain a sliver and spinning 132 the sliver to obtain a product.

In one aspect, the disclosure relates to composite fibers having a structure comprising a core component and sheath component, wherein each of the core component and the sheath layer independently comprise a polymer and a disclosed cooling composition. In various further aspects, the present disclosure pertains to single-covered yarn comprising a core yarn comprising a disclosed composite fiber comprising a core component and a sheath component. In still further aspects, the present disclosure pertains to a fabric, such as a denim fabric, comprising a disclosed single-covered yarn. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

Provided herein is a new fire barrier material composed of flame retardant (FR) cellulosic fiber(s) and one or more of an antimicrobial (AM) cellulosic fiber and an untreated cellulosic fiber(s). The fire barrier material may be a fabric woven or knitted from the yarn containing the FR cellulosic fiber(s) and the one or more of AM cellulosic fibers and untreated cellulosic fibers. When AM cellulosic fibers are combined with FR treated cellulosic fibers, the fire barrier material has the dual features of flame retardancy and antimicrobial properties. The fire barrier material may also be a nonwoven, and in preferred embodiments optionally includes a binder fiber. The FR cellulosic fiber contains FR chemical(s) or FR compound(s) that have a melting point or decomposition temperature at 400 C. (752 F.) or below. The FR performance of the new nonwoven provided herein is comparable to the conventional FR nonwoven (FR cellulosic fiber/binder fiber), but has advantages in cost effectiveness, as well as antimicrobial properties.

A fiber assembly including fibrils including a fibril which is a part of a fiber extending in a direction of thickness of the fiber assembly and including a network structure formed with a binding portion resulting at least any from binding between fibrils and binding between a fibril and a fiber in at least any end portion in the direction of thickness of the fiber assembly and a liquid absorbent sheet-like article including the same as well as a fiber assembly which is excellent in diffusion of a liquid particularly at a surface and absorption thereof in the inside and includes fibrils and a liquid absorbent sheet-like article including the same as well as a method of manufacturing the fiber assembly can be provided.

Embodiments of the present invention relate to flame resistant fabrics formed with inherently flame resistant fibers that provide the requisite thermal and arc protection, that have improved comfort, and that, in some embodiments, are less expensive than other fabrics formed with inherently flame resistant fibers. Improved comfort and lower cost can be achieved by predominantly locating the inherently flame resistant fibers on the front face of the fabric to impart the requisite thermal and arc protection and predominantly locating the more comfortable (and less expensive) fibers on the back face of the fabric positioned next to the wearer. In this way, overall protection of the fabric is maintained while improving comfort. Some embodiments of such fabrics may also achieve NFPA 70E PPE Category 2 protection.

Disclosed herein is a light transmissive fiber integrated knit textile for use on consumer electronic products. The knit textile is depicted to be constructed with light transmissive fibers integration through a weave-in/inlay knit technique with a flat-bed knitting construction. The light transmissive knitted textile is also tethered to a portable electronic device, allowing for the light transmitting fibers knitted into the fabric to define a lighting display on said fabric.

A modular system and process are described for recycling textile waste of various compositions into new ready to use fibers for garment manufacturing or other uses.

A V-ribbed belt in which a frictional power-transmission surface is formed from a weft knitted multilayer knitted fabric is provided, in which the weft knitted multilayer knitted fabric contains cellulose based natural spun yarn, polyester based composite yarn, and polyamide based yarn, and in that at least the cellulose based natural spun yarn and the polyamide based yarn are disposed in a layer on the frictional power-transmission surface side.

Flame resistant fabrics formed with fiber blends that provide the requisite flame and thermal protection but that have improved durability. In some embodiments this is accomplished with the use of fiber blends that include relatively large percentages of FR nylon fibers in combination with cellulosic and inherently flame resistant fibers.
