A method for preparing a high fluffiness down by multiple treatments with metal salts includes: degreasing a down sample with a degreasing agent; washing the down sample with water; oxidizing the down sample with an oxidizing agent; washing the down sample with water; conducting a first crosslinking treatment with basic zirconium sulfate; washing the down sample with water; conducting a second crosslinking treatment with basic aluminum sulfate; washing the down sample with water; and drying the down sample to obtain the high fluffiness down.

Silk coated and/or infused performance materials, apparel, and methods of preparing the same are disclosed herein. In some embodiments, silk performance apparel includes textiles, fabrics, consumer products, and other materials that are coated with aqueous solutions of pure silk fibroin-based protein fragments having low, medium, and/or high molecular weight in various ratios.

A high density mineral fibre board having a formaldehyde free binder has acceptable strength and good dimensional stability.

Combined insect repellents and odor-reducing compositions are disclosed that use the insect repellent Picaridin [2-(2-hydroxyethyl)-1-piperidine carboxylic acid 1-methylpropyl ester] in combination with the odor-reducer zinc ricinoleate are disclosed, as are methods for using these compositions. The presence of the odor reducer does not reduce the apparent efficacy of the Picaridin, and tends to reduce the odor of the Picaridin itself.

The invention provides a silver-plated conductive nylon fiber and a preparation method thereof. The method includes: immersing a nylon fiber in an aqueous solution containing a polyphenolic compound at 60 C. to 70 C., adding a water-soluble oxidant into the solution, continuously reacting at 70 C. to 80 C., and obtaining a polyphenol grafted nylon fiber, where the polyphenolic compound contains a catechol group; immersing the polyphenol grafted nylon fiber into a solution containing silver ions at 15 C. to 25 C. for reaction, and raising the temperature to 70 C. to 80 C. for continuous reaction to obtain a surface-activated nylon fiber; and carrying out chemical silver plating treatment on the surface-activated nylon fiber to obtain the silver-plated conductive nylon fiber. The method does not require a heavy metal sensitizer and therefore is non-toxic and environment-friendly, and the fiber strength is maintained.
