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 knitted fabric with leather fibers comprising a ground yarn layer and a face yarn layer directly connected with the ground yarn layer through double knitting. The ground yarn layer includes a plurality of first yarn loops, each of the first yarn loops is formed by a plurality of ground yarns. The face yarn layer includes a plurality of second yarn loops, each of the second yarn loops is formed by at least one face yarn attached with the leather fibers obtained from a piece of leather by a pulverization operation. A course ratio of the face yarn layer to the ground yarn layer is in a range between 1:1.25 and 1:4. Accordingly, the invention provides an innovative knitted fabric and solves the problem that the leather cannot be recycled after being discarded.

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.

The present disclosure relates to a hydrogel fibre comprising an ionic hydrogel and a second component in a plurality of compartments, wherein the second component is selected from a second hydrogel, a hydrophilic solution, or a mixture thereof. It is also disclosed the method to obtain the aforesaid hydrogel fibres. This disclosure also relates to a composition comprising the hydrogel fibres and a suitable carrier, and an article/kit, a bundle, a mesh or a membrane comprising the hydrogel fibre. A composition comprising an ionic hydrogel and a second component for use in medicine administered in a hydrogel fibre comprising a plurality of compartments is also disclosed.

A method for producing a protein polymer fiber, the method comprising providing a liquid protein solution in a container for liquid, and repeatedly moving the liquid surface in the container back and forth between a first and a second position. Said movement of the liquid surface is such that the protein polymer solution is allowed to form a film in the interface between the liquid surface of the liquid protein solution and a surrounding fluid. The movement of the liquid surface being performed by respectively raising and lowering the liquid surface relative to the container or by moving an object extending through the liquid surface of the liquid protein solution. Also, a device for performing said method.

The present invention provides a knitted fabric with leather fibers comprising a ground yarn layer and a face yarn layer directly connected with the ground yarn layer through double knitting. The ground yarn layer includes a plurality of first yarn loops, each of the first yarn loops is formed by a plurality of ground yarns. The face yarn layer includes a plurality of second yarn loops, each of the second yarn loops is formed by at least one face yarn attached with the leather fibers obtained from a piece of leather by a pulverization operation.

Accordingly, the invention provides an innovative knitted fabric and solves the problem that the leather cannot be recycled after being discarded.

A method of manufacturing a collagen yarn includes providing collagen fiber. The collagen fiber is spun into a yarn and tanned subsequent to the spinning of the yarn.

The present invention provides an artificial bionic blood vessel and a manufacturing method thereof. The artificial bionic blood vessel includes a three-layer-structured artificial bionic blood vessel body, where the three-layer structure of the artificial bionic blood vessel consists of a natural silk layer, a diluted liquid silica-gel layer and a weaved tube layer, the diluted liquid silica-gel layer is located on the inner side of the natural silk layer, the weaved tube layer is located on the outer side of the natural silk layer, and the weaved tube layer is made of catgut by weaving.

This disclosure relates generally to the preparation of eco-friendly engineered fabric, and more particularly to terry fabric and variations thereof. In one embodiment, a terry fabric is comprised of a soluble fiber blend, blended with cotton fibers, where the soluble fibers are dissolved in a caustic or enzyme solution to create highly porous yarns.

A microelectrode array comprises three or more flexible oblong, electrically co-operating microelectrodes in wire and/or ribbon form disposed substantially in parallel. The microelectrodes are electrically insulated except for at a distal section thereof. The array further comprises electrically non-conducting microfibres connecting central portions of the microelectrodes in oblique directions in respect of the array axis. In a preferred array variety the microelectrodes are joined by a glue that is dissolvable or degradable in aqueous body fluid. Also disclosed is a combination of two or more arrays of the invention.
