The invention relates to a skin-friendly fish scale protein modified nylon-spandex fabric and its processing technology. The fabric is made of fish scale protein nylon DTY and spandex by weft knitting. The spinning process of the fish scale protein nylon DTY includes the steps of: sequentially carrying out spinning, cooling, oiling and winding on fish scale protein masterbatch and PA6 slices to obtain POY; and then post-processing the POY to obtain the fish scale protein nylon DTY. According to the invention, the fish scale protein masterbatch and the PA6 slices are blended and melt-spun to prepare the fish scale protein nylon DTY, and through special treatment, the PVA crosslinks with and wraps the fish scale protein peptide powder; and then freezing, thawing and crushing are carried out repeatedly to obtain porous PVA-modified fish scale protein peptide powder. On one hand, PVA has good compatibility with the PA6 slices. On the other hand, PVA wraps the fish scale protein peptide powder. In this way, the activity of the fish scale protein can be prevented from damage during the spinning and melting process, the original good antibacterial drying, moisture absorption and moisturizing properties and biocompatibility of the fish scale protein can be maintained and elongation at break can be further enhanced and the spinnability can be improved greatly.

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.

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.

A nanofiber comprising a cross-linkable protein polymer and a transglutaminase. A method for producing a nanofiber, the method comprising: combining a first solution comprising a cross-linkable protein polymer and a second solution comprising a transglutaminase to produce a liquid electro spinning mixture (LEM) characterized by an environment that is unsuitable for the transglutaminase to be enzymatically active on the cross-linkable protein polymer; and electro spinning the LEM to form a nanofiber comprising the TGase and the cross-linkable protein polymer.

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.
