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.

A blend composition includes polyamide fiber and denatured collagen. The polyamide fiber content is 97-99.9 parts by weight in the blend composition. The denatured collagen content is 0.1-3 parts by weight in the blend composition. The denatured collagen has a first polypeptide, a second polypeptide, and a third polypeptide. The amide groups of the first polypeptide, the second polypeptide, and the third polypeptide are linked with the amide groups of the polyamide fiber through hydrogen bond formation. A method of manufacturing a blend composition is provided herein.
