A hybrid woven textile for reinforcing a polymer matrix of a composite material that includes inorganic fibers selected from glass fibers, basalt fibers, carbon fibers, ceramic fibers, quartz fibers and silica fibers, and natural organic fibers, characterized in that the inorganic fibers and the natural organic fibers are co-woven, co-braided or co-knitted with one another.

Disclosed are a method for preparing spun leather yarn using leather fiber, and spun leather yarn prepared according to the preparation method. The spun leather yarn prepared according to the preparation method enables the manufacture of fabrics, knitted goods, and lace goods, which have the character of leather, and thus can be effectively used for various fashion applications. In addition, the spun leather yarn can replace existing leather materials, which have been used in bags, athletic shoes, and the like, and thus is not affected by material supply in accordance with seasonal changes, and accordingly, the economic effect thereof is excellent. Moreover, the spun leather yarn has warmth retention and general flame retardancy, which are the properties of natural leather, and thus is of very high quality.

Coaxial electrospinning is used to encapsulate a chitin-lignin based hybrid gel with polycaprolactone (PCL). Antibiotics and/or other bioactive agents loaded into the core and/or shell layer of the fibrous platform are released in a controlled and sustained manner that effectively inhibits both Gram-positive and Gram-negative bacteria without cytotoxicity to mammalian cells. The PCL shell layer provides longer life for the CL gels in a wet environment and allows sustainable drug release. The PCL-coated CL nanofiber scaffolds can be loaded with antimicrobial nanoparticles, antibiotics, oxygen-releasing agents, antioxidants and/or growth factors that promote healing when used as a controlled drug release dressing for chronic wounds, such as diabetic ulcers.

A conventional sock, in which a pile yarn knitted into loops together with a polyurethane yarn has cushioning properties, but has a problem in that it cannot be used for a long period of time. According to the present invention, a first component yarn 15a composed of two yarns, namely, a woolly nylon yarn 13a and a cotton yarn 14a, and a second component yarn 15b composed of two yarns, namely, a woolly nylon yarn 13b and a cotton yarn 14b, are alternately knitted into float loops every 10 loops. Accordingly, the cotton yarns that are less stretchable appear on the surface, and thus cushioning properties can be improved. Also, the yarn strength can be increased by the woolly nylon yarns that are highly stretchable, and also the strength can be further increased by using the component yarns each composed of two yarns: a woolly nylon yarn; and a cotton yarn. Accordingly, the obtained sock can be used for a long period of time.

A composite textile is provided. The composite textile includes a textile substrate and a thermal material layer formed on the textile substrate. The thermal material layer includes a nanocomposite powder. The nanocomposite powder is composed of a pyrrolidone-containing polymer and an inorganic particle. The pyrrolidone-containing polymer is polyvinylpyrrolidone, a derivative of polyvinylpyrrolidone or a combination thereof. The inorganic particle is a metal oxide composed of a first metal M.sup.A, a doping metal M.sup.B and oxygen. The inorganic particle makes up 62.5-99.9 wt. % of the nanocomposite powder.

The present disclosure relates generally to pre-treating textiles and methods of preparing textiles in a pre-treated state. Specifically, the present disclosure relates to pre-treating textiles comprising recombinant protein fibers.

Compositions and methods are provided for recombinant protein fiber yarns engineered to have desirable properties along with textiles made using such yarns. Recombinant protein fibers (RPFs) whose properties can be influenced by their composition, structure and processing to obtain improved combinations of mechanical properties, chemical properties, and antimicrobial properties for a given application are presented, along with methods of producing those fibers. The present disclosure also presents filament yarns, spun yarns, and blended yarns formed using these fibers that can be used to manufacture textiles suitable for different applications. Additionally, the combinations of RPFs with certain properties, and yarns and textiles produced from those yarns with certain structures yield yarns and textiles with certain properties designed for various applications.
