Disclosed is a method of preparing a knitting yarn having a water-repellent function, including providing a knitting yarn in the form of a skein or a cone, washing the provided yarn to remove impurities and oil therefrom, coating the washed yarn with a water-repellent agent by spraying a water repellent solution containing the water-repellent agent at a predetermined pressure, dehydrating and drying the coated yarn, and fixing the water-repellent agent to the yarn by applying heat to the dried yarn.

The present invention relates to a wool treatment process and to a wool product produced by the wool treatment process. In particular, the invention relates to a wool treatment process that produces a wool product with increased absorbency properties and to a wool product that has increased absorbency properties.

Disclosed are keratin fibre cellular components, specifically keratin fibre cuticle and cortical cells, and their use as absorption and filtration media, and in thermal insulation materials. The keratin fibre cellular components may be oxidised. The keratin fibre cellular components have improved absorbency and filtration capacity compared to the source keratin fibres. The keratin fibre cellular components may be used in, for example, various products for passive absorption and active filtration of gas or liquid media.

The present invention relates to a method for producing a protein fiber, including a step of bringing a protein raw fiber containing a protein into contact with water vapor in a storing chamber in which a temperature is adjusted within a range of less than 120° C. to perform heat treatment of the protein raw fiber.

An object of the present invention is to provide a method for producing protein spinning capable of securing a stable strength by securing sufficient interlacing between fibers. The method for producing a protein spun yarn of the present invention includes a step (a) of preparing a raw material spun yarn including an uncrimped artificial fibroin fiber containing modified fibroin and a step (b) of bringing the raw material spun yarn into contact with an aqueous medium to crimp the artificial fibroin fiber.

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.

Disclosed herein is an electrode material comprising: a non-woven silk-fibroin mesh substrate; glycerol; and a conductive polymeric material, wherein 40-65% of the silk-fibroin in the non-woven mesh substrate is in the form of β-sheets, and the electrode material is stretchable. Also disclosed herein is a method of forming said electrode material.

This document discloses an electrically conductive fiber coated with polythiophene and a carbon material. Also disclosed is an article of manufacture incorporating the conductive fiber.

A welding process may be configured to convert a substrate into a welded substrate by applying a process solvent 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 be configured as an ionic-liquid based solvent and the welded substrate may be a congealed network after the process solvent has been adequately swollen and/or mobilized the substrate. A welding process may be configured such that individual fibers of a substrate are not fully dissolved such that material in the fiber core may be left in the native state by controlling process variables. The welding process fibers may have a tenacity 10% or 20% greater or a diameter 25% less than that of a cellulosic-based yarn substrate.

Chemical compositions and techniques for treating wool (and other animal hair-based) fabrics are provided. In particular, compositions and techniques for unshrinking wool fabrics and garments are provided.
