Silver-plated conductive nylon fiber and preparation method thereof
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.

Antimicrobial textile products and method of obtaining thereof
The present invention relates to a method of obtaining antifungal, anticandidal and antibacterial textile products. The objective of the present invention is to obtain an antimicrobial product, which enables to reduce the infectious diseases that are transmitted or spread by textile products, reduces extra cost and energy spent for ensuring hygiene, and increases hygienity of disposable textile products. A solution of triclosan, chlorhexidine and disodium octaborate pentahydrate is used in the method of the present invention. The said solution enables the hydrophobic textile products to be transformed into hydrophilic products and thereby enables the antimicrobial agents in the solution to be coded into the textile products.

METHOD OF MAKING WET WIPE FOR RAPID DETECTION OF OPIOIDS
A substance detector includes curcumin and is safe for human handling. The curcumin, as part of a wetting agent of the substance detector, changes color on contact with opioids and related illicit substances. A corresponding method detects very small quantities of an opioid via a rapid color change on a wet wipe when contacted with the opioid. Because the color change takes place on the wet wipe relatively quickly, there is no need to mix reagents to produce a color change reaction.
