Provided is an infrared-absorbing fiber, knit fabric, or non-woven fabric containing an infrared-absorbing pigment, wherein L* in the CIE 1976 color space is at least 30, and the color difference ΔE in the CIE 1976 color space between said infrared-absorbing fiber, knit fabric, or non-woven fabric and an infrared-absorbing fiber, knit fabric, or non-woven fabric containing no infrared-absorbing pigment is at most 10.

Disclosure provides antimicrobial fiber, comprising: a cationic or polycationic moiety grafted onto a cellulosic fiber and an anionic photosensitizer. Exposing the antimicrobial cotton fiber to light generates reactive oxygen species (ROS) and induces a biocidal function.

Applied in the field of manufacturing textile products, the present invention provides compositions of synthetic polymeric fibers containing from 0.25% to 4.00% of lignin originated from the Kraft process, which are incorporated into the polymer through a subsequent extrusion process with the spinning process, by the use of a double-screw extruder coupled to a spinnerette. The obtained fibers are used in the production of textile products with anti-UV properties due to the presence of lignin, and with greater tenacity, resistance to bursting and antioxidant activity of the knit.

An infrared reflecting fiber includes 76.0 parts by weight to 88.5 parts by weight of a carrier, 1.8 parts by weight to 4.0 parts by weight of an infrared reflecting composition, 2.5 parts by weight to 7.5 parts by weight of a titanium dioxide containing composition, and 6.0 parts by weight to 16.0 parts by weight of a color adjusting composition. The carrier includes polyethylene terephthalate (PET). When a content of 5.0 wt % to 7.5 wt % of the infrared reflecting composition and a balance of the carrier are mixed together to form a first fiber, a maximum infrared reflectivity of the first fiber is between 61% and 70%.

The present invention discloses a graphene composite material and a preparation method thereof. By adding pleated graphene oxide microspheres and a catalyst to a precursor, the pleated graphene oxide microspheres are allowed to be highly dispersed and gradually disassociated into single-layer graphene oxide sheets during the process of polycondensation, the partially esterified molecules react with the hydroxyl and carboxyl group on the surface of graphene oxide sheets to form a chemical bond, and the graphene oxide is thermally reduced, to finally obtain a composite material comprising PET and graphene sheets having PET grated to the surface.

Far-infrared fibers, and components and uses of the same are provided. The far-infrared fibers can be used together with other optional fibers to provide a product containing far-infrared fibers. The product does not emit harmful radiation and could raise a user's body temperature safely to increase the volume and rate of the user's blood flow without affecting the blood pressure and pulse of the user. Furthermore, the product can be male underpants that can improve male sexual function without affecting the physiological state.

Additives such as colourants may be incorporated into polymeric materials such as polyesters, such as in polyester fibre production, by use of a liquid formulation comprising colourant and a vehicle. The vehicle may comprise a functionalised pentaerythritol, trimethylolpropane or trimellitate. The liquid formulation is suitably contacted with the polymeric material in a melt processing apparatus.
