Provided is a fiber for rubber reinforcement that can be produced using a bio-derived raw material and hardly breaks even when compounded with a rubber material. A first fiber for rubber reinforcement uses a protein fiber containing a hydrophobic protein. A second fiber for rubber reinforcement uses a protein fiber having an initial tensile modulus of elasticity of 2.0 GPa or more when wet. These fibers for rubber reinforcement preferably have a coating layer made of a water-based adhesive composition on the surface thereof.

The present invention provides a biological tissue adhesive sheet having excellent tissue adhesiveness. The biological tissue adhesive sheet according to an embodiment of the present invention includes a nonwoven fabric made of fibers containing a crosslinked cold-water fish gelatin. Thereby, the biological tissue adhesive sheet according to the present invention is superior in tissue adhesiveness and film strength to conventional medical sheets.

A water filtration membrane is provided, capable of removing heavy metal ions, filtering out particulates, filtering out bacteria, as well as removing herbicides and volatile organic compounds (VOCs) from water. The membrane is composed of a mat of randomly oriented nanoparticle-coated nanofibers. The nanofibers are covalently bonded to a plurality of substantially uniformly-distributed ceramic nanoparticles embedded in or adhered on the surface of the polymer nanofibers through reactive functional groups. The ceramic nanoparticles have a pattern of deep grooves formed on the nanoparticle surfaces. The bonding of the nanoparticles to the nanofibers is sufficient to retain the nanoparticles on the nanofiber surfaces when water flows through the water filtration membrane. The diameter of the nanofibers is 50-200 nm. The size of the nanoparticles is <40 nm, with a zeta potential of −40 to −45 mV in a dispersion medium. The nanoparticle deep grooves have an average size of approximately 1.2 nm or less.

The present invention provides an anti-pilling wool fabric with a coating having pilling resistance and resistance to fiber loss from fabric surface. The coating is formed by a coating formulation including at least two diisocyanates, at least two catalyst, a water dispersing agent, a buffer and water, which provides a polycarbodiimide crosslinker reactive to the relative less reactive groups on polypeptide of the wool fabric and promotes crosslinking between polypeptides of the wool fabric under relatively mild processing conditions so as to enhance mechanical strength of the wool fabric whilst no significant effect of the original finish merino wool fabric and/or garment and fiber loss from fabric surface are observed, compared to conventional treatment methods on wool fabric. A corresponding coating formulation and method of fabricating the anti-pilling wool fabric are also provided. The present invention is applicable to finished wool fabric which fibers are already with colorant(s), and/or dye(s), and/or reactive dye(s).

Result of the successive steps described in this invention: light, durable, decorative elements having a stable three-dimensional shape are obtained. The mounting method is in such a way as not to damage the surface.

The manufacturing method described in this invention implies do not use ready-made material, but create each product by hand puling out very small strands of natural organic fibers of fine wool, a layer-by-layer application to the template/mold takes place and a further multistage process of forming the product.

Then polyurethane varnish is applied in accordance with a specific technology disclosed in this invention and each individual element is formed, then leaving the elements to dry completely naturally at room temperature;

After each element is dry and three-dimensional stable, need gluing at least one magnet to the surface of each element, also need gluing the magnet to the surface using double-sided tape according to the number of magnets located on each individual element and last step to connecting of magnets on each element with a magnet on the surface;

Decorative elements created according to the method of this invention do not need a rigid base and have good adhesion to the wall without drilling holes in the wall.

These elements are intended for decoration of interior surfaces, in particular, but not exclusively walls, in order to decorate the interior and improve the emotional wellbeing of people of all ages. Despite the stable three-dimensional shape, these decorative elements are safe to use, because they are easily to attach without any secondary skills and safely, injury is excluded when the decorative element falls because they are lightweight and do not have hardness that can cause harm in the event of fall, this makes a high level of safety.

Natural wool is a difficult material to produce sculpted three-dimensional shapes that can be attached to a wall. A common practice of natural wool fibers is to two-dimensional art or suspended three-dimensional objects not represent attached to a wall. Therefore, the technology of creating decorative elements from natural non-spun wool fiber is a new level of development of the decor of working with natural wool fibers.

Provided is a recycling method of polyester wool blended fabric, which includes the following. A polyester wool blended fabric containing a dye is put into an acidic aqueous solution containing an oxidizing agent for heating and soaking, so as to degrade a wool in the polyester wool blended fabric, and perform decolorization at the same time to remove the dye. After that, a polyester fabric is obtained by filtration.

Provided are MOF-fabric composites having a crystalline MOF adhered directly to fibers of the fabric and methods of making MOF-fabric composites. A solution is adsorbed onto a fabric. The solution can include a metal salt, a linker, and a solvent. The solution is adsorbed onto the fabric and the fabric suspended over a heated vapor. The vapor releases onto the fabric, causing the metal salt, the linker, and the solvent to diffuse out of the polymer fibers. The linker links metal from the metal salts to form crystals attached to the fabric, and the vapor aids crystallization.

The present invention relates to a method for manufacturing a protein fiber, including an extension and contraction step of contracting or extending a protein raw fiber containing a protein by bringing the protein raw fiber into contact with a liquid or vapor; and a drying step of drying the protein raw fiber that has undergone the extension and contraction step while adjusting a length of the protein raw fiber to an arbitrary length.
