A fiber is provided as a substrate for a functional nanostructure (coated fiber), composed of (a) a fiber substrate; (b) a reactive dye conjugating moiety covalently bound to the fiber substrate; (c) a bonding agent covalently bound to the reactive dye conjugating moiety; and (d) the functional nanostructure bound to the bonding agent. A method of making the coated fiber is also provided, involving the following steps in any order: covalently binding the reactive dye conjugating moiety to the fiber; covalently binding a bonding agent to the reactive dye conjugating moiety; and binding the functional nanostructure to the bonding agent. The nanostructures are tenaciously attached to the fibers, resisting very rough treatments, and can be made using inexpensive and widely available reactive dyes under non-stringent synthesis conditions.

A wet treatment process, the process comprising: adding an article comprising a polymer and an initial zinc content to a wash solution comprising solute and a wash solution zinc content; maintaining the article in the wash solution for a wash time greater than 10 seconds to yield a washed article comprising a washed zinc content; wherein the washed zinc content is greater than the initial zinc content; and wherein the washed article demonstrates a Klebsiella pneumonia log reduction greater than 0.90, as determined via ISO20743:2013 and/or an Escherichia coli log reduction greater than 1.5, as determined via ASTM E3160 (2018).

The present invention may provide a screen used for screen golf, which can improve the brightness and clarity of the image projected on the screen by suppressing the light of the image from passing through the screen and increasing the reflectance of light from the front of the screen when an image is output by a projector on the screen. In addition, despite repeated golf shots of many users, the brightness and clarity of the image projected on the screen may not be damaged.
