A method for manufacturing a deodorant and antibacterial high-strength protective cloth includes: providing a first fiber thread and a second fiber thread, where the first fiber thread is a core-spun yarn formed by a blended slurry, a nano metal solution, a plurality of inorganic particles, and a plurality of thermoplastic polyurethane colloidal particles, the thermoplastic polyurethane colloidal particles are hot melted and then wrapped around a peripheral side of a core thread of the core-spun yarn for isolation from an outer wrapping layer of the core-spun yarn, and the second fiber thread is the same as the first fiber thread or is a single-thread yarn formed by the blended slurry and the nano metal solution; and intersecting and laminating the first fiber thread and the second fiber thread to form a plurality of bonding layers.

A system for the treatment of microorganisms includes: a textile web having optical fibers in warp and/or weft woven with binding threads in warp and/or weft, each of the optical fibers having invasive alterations along the fiber and allowing the emission of light propagating in the fiber at these alterations; a light source arranged opposite one or both free ends of the optical fibers. The textile web includes metallic warp and/or weft threads woven with the binding threads, the metallic threads being based on a metal having a negative effect on the growth of microorganisms. The light source generates a light beam having at least one wavelength in the visible or ultraviolet spectrum.

Exercise straps including an antimicrobial fiber are disclosed herein. The antimicrobial fiber is capable of eliminating or at least reducing the number of bacteria, viruses, and/or fungi, etc. on an exercise strap while also providing the requisite amount of tensile strength to form a portion of an exercise machine and/or device (e.g., a Pilates Reformer, Tower, Cadillac, Chair, and Barrel, etc.) and/or to perform an exercise program (e.g., a Pilates routine, etc.). The antimicrobial fiber includes antimicrobial threads of a salt fiber and a non-salt fiber interwoven to form an exercise strap.

A biodegradable antibacterial knitted fabric, a cross section of the knitted fabric includes a front side of cross section made of wool short fiber yarns, an intermediate connection layer of cross section capable of transferring moisture and a rear side of cross section made of antibacterial filaments; the intermediate connection layer of cross section is made of filament yarns having a special shape capable of being inserted into the front side of cross section and the rear side of cross section so that the front side of cross section is connected with the rear side of cross section. The biodegradable antibacterial knitted fabric proposed by the present application has a long time significant antibacterial effect by adopting a cross section structure with three layers and antibacterial material, and does not contain any antimicrobials and metal ions, and has the advantages of low cost, easy manufacturing and long lasting antibacterial effect.

A yarn, fabric, or garment that includes a plurality of fibers or a fiber-based material. The yarn, fabric, or garment includes lignin as a primary dye agent. Lignin may be present in the plurality of fibers or the fiber-based material in a range of 0.3 percent to 10 percent by weight.

A yarn containing a potential-generating filament. The yarn is constructed such that a positive or negative surface electrical potential is generated by applying an external force to the yarn in an axial direction of the yarn, and constructed such that a controlled surface electrical potential is generated by a maintenance or release of the external force.

Technologies for fibers with nanotechnology is disclosed. In the illustrative embodiment, a preform is 3D printed with one or more sacrificial cores and one or more hollow channels. The preform is drawn into a fiber, and one or more metal core(s) is inserted into the hollow channel during the fiber draw. The fiber is then heated, breaking up the sacrificial cores into balls through capillary action. The fiber can be etched, exposing the balls made up of the sacrificial cores. The balls can be selectively etched, exposing the metal core(s) of the fiber. Additional embodiments are disclosed.

A yarn containing a plurality of potential-generating filaments. The yarn is characterized in that the plurality of potential-generating filaments are constructed such that the yarn has a specific permittivity of 4.5 or less. In a specific configuration, the plurality of potential-generating filaments are constructed such that the distance between the potential-generating filaments is about 0 μm to about 10 μm. Also provided is a fabric that contains the yarn.

A deodorant and antibacterial copper nanofiber yarn and a manufacturing method thereof are provided, the manufacturing method including: providing a raw material, including a polyblend slurry, a nano-metal solution, a plurality of inorganic particles, and a plurality of TPU rubber particles; stirring the raw material into a mixed material; making second metal contact the first metal ion fiber to cause the first metal ion to undergo a reduction reaction to obtain a copper nanofiber yarn; drying the mixed material; performing hot-melt spinning on the mixed material, the plurality of TPU rubber particles, after being hot-melted, being coated on an outer peripheral side of the spun wire to form a first-phase wire; forcibly cooling the first-phase wire; stretching the first-phase wire; air-cooling the first-phase wire to form a second-phase wire; and collecting the second-phase wire to make the wire into a finished deodorant and antibacterial copper nanofiber yarn.

An animal leather fiber bundle, yarn, core-spun yarn and products with nanoscale branches is disclosed. The animal leather fiber bundle with nanoscale branches has an animal leather fiber body, which is a spinnable animal leather fiber body. The animal leather fiber body has nanoscale branches, the yarn is formed of animal leather fiber bundles with nanoscale branches, the core-spun yarn has a core yarn and a skin layer, the skin layer has animal leather fiber bundles with nanoscale branches, and the product is made of any one of the above. The disclosed structure has independent and separated nanoscale branches.
