The frictional power transmission belt includes a frictional power transmission surface formed of a composite fibrous layer containing a fibrous member, an isocyanate compound, and a resin component, wherein the fibrous member contains a cellulose-based fiber. A proportion of each of the isocyanate compound and the resin component in the composite fibrous layer may be 2 to 15% by mass.

A functional fabric is formed by bonding a polyester synthetic resin film mixed with carbon black fine particles to a fabric, in which the synthetic resin film is non-porous and has a thickness of 10 μm to 20 μm. The functional fabric is produced by producing a polyester synthetic resin film mixed with carbon black fine particles and bonding the synthetic resin film to a fabric, and the produced functional fabric is entirely or partially bonded to an inner wear or an intermediate clothes to produce clothing.

A piezoresistive sensor featuring a fabric of woven or nonwoven fibers coated with carbon nanotubes can be integrated with footwear or clothing to serve as a pressure sensor that can monitor and/or analyze human activity during the course of the activities of daily living of the wearer.

A dyeing and welding process may be configured to convert a substrate into a welded substrate having at least some color imparted thereto via a dye and/or coloring agent by applying a process solvent having a dye and/or coloring agent therein to the substrate, wherein the process solvent interrupts one or more intermolecular force between one or more component in the substrate. The substrate may be configured as a natural fiber, such as cellulose, hemicelluloses, and silk. The process solvent may include a binder, such as dissolved biopolymer (e.g., cellulose). After application of a process solvent comprised of a dye and/or coloring agent, the substrate may be exposed to a second application of a process solvent comprised of a binder, which second application may occur before or after a process temperature/pressure zone, process solvent recovery zone, and/or drying zone.

The present disclosure discloses an atmospheric-pressure plasma equipment for fabric functional finishing and its application, and belongs to the field of textile printing and dyeing engineering. The atmospheric-pressure plasma equipment, including a discharging system, a grafting instrument and a cloth guider, can conduct continuous plasma treatment on fabrics under an atmospheric pressure, including plasma etching and plasma grafting, which breaks through the disadvantage of batch processing of vacuum plasma equipment. The equipment and method of the present disclosure realize functional finishing of the fabrics in the absence of water, and this finishing process is cost efficient, environmentally friendly, uniform, shorter treatment time and higher reactivity, and applicable to many materials and can keep the bulk properties of the treated substances.

Provided herein are surface treating compositions for imparting beneficial surface properties to substrates. The compositions can be prepared by reacting a bio-based polyol with an isocyanate and an ionogenic molecule. The compositions can be used to treat a variety of substrates to provide enhanced properties to a surface of the substrate. Also provided are methods for the chemical modification of triglycerides and fatty acids and use thereof in creating beneficial surface treating compositions.

A method is provided for coating a fibrous web, in particular a fibrous web comprising nanocellulose fibres. The method includes steps of applying a coating agent to a textured surface region of a textured substrate, applying a fibre furnish or a wet fibrous web onto the coated textured surface region of the textured substrate, optionally dewatering to provide a wet fibrous web, and drying said wet fibrous web such that at least a portion of said coating agent is transferred to said fibrous web. The method provides a coated fibrous web with improved barrier properties.

The present disclosure is directed to an oil-infused bacterial nanocellulose (BNC) material including a porous body comprising a three-dimensional network of bacterial nanocellulose fibers defining a plurality of interconnected pores; and, an oil infused within the plurality of pores. The present disclosure additionally describes a method of preparing an oil-infused BNC material that includes fermenting bacteria to form a porous body of bacterial nanocellulose fibers having a three-dimensional network defining a plurality of interconnected pores; mechanically pressing the porous body; dehydrating the porous body; and infusing the porous body with an oil infusion fluid including an oil so as to entrap the oil in the pores of the porous body forming an oil-infused BNC material.
