DETAILED DESCRIPTION OF THE INVENTION

(12) Methods for hydrophobizing bowstrings are described herein. The method can include applying a hydrophobizing coating to the bowstring. The hydrophobizing coating can be a car coating spray that includes a silicon nanoparticles. The spray can bond with the composition of the bowstring after a curing period, which can hydrophobize the bowstring. Thus, the spray can last significantly longer than conventional waxes, and does not significantly affect the weight of the bowstring.

(13) The hydrophobic coating can be composed of silicone nanoparticles. In some cases, the coating can also be composed of an alcoholic solution. In particular, an embodiment of the hydrophobic coating can be the ZXL-Rain spray. However, other hydrophobic, silicone-based coatings for automobiles can be used as well, such as Chemical Guys HydroSlick SiO2 Ceramic Coating Hyperwax, Nasiol ZR53, The Last Coat Black Ice Ceramic Coating, CarPro CQuartz UK 3.0, and the like.

(14) FIG. 1 depicts an image of applying a hydrophobizing coating according to an embodiment of the present disclosure. The coating can be in liquid form, and can be sprayed onto the bowstring. The image of FIG. 1 depicts a user spraying the coating onto the surface of the bowstring. The bowstring can be stretched for ease of the coating application (e.g., the bowstring is coupled to a bow prior to application). In some cases, the bowstring can be stretched in a horizontal fashion, or in a vertical fashion, for applying the coating. In some cases, the coating can be sprayed a sufficient number of times to cover the surface of the bowstring, for example, 10 pumps of the spray. In some cases, the coating can be wiped along the length of the bowstring (e.g., with a towel or a user's finger). In some cases, the spray can be a distance away from the bowstring for sufficient coverage of the bowstring when sprayed (e.g., 6 inches away, 12 inches away, and the like). Further, the coating can be applied across the entire surface of the bowstring for sufficient coverage.

(15) FIG. 2 depicts an image of liquid being placed onto the bowstring after hydrophobizing the bowstring. After a curing period subsequent to the application of the coating, the coating can form a semi-permanent bond with the bowstring surface. In some cases, the curing period can be a sufficient amount of time for the coating to cover the surface of the bowstring (e.g., 5 seconds, 10 seconds, 30 seconds, 1 minute, and the like). In other cases, the curing time can be a sufficient amount of time for the coating to dry on the surface of the bowstring (e.g., 1 minute, 2 minutes, and the like). In some cases, the bowstring can be isolated from contacting surfaces during the curing time, so as to not smear or remove the coating from the surface of the bowstring. FIG. 2 depicts an image of liquid being placed on a hydrophobized bowstring according the methods described herein. As can be seen, the liquid does not absorb into the bowstring, and instead wicks off the bowstring surface. FIG. 3 depicts an image of liquid being placed on an un-hydrophobized portion of a bowstring. As shown in FIG. 3, the liquid becomes partially absorbed into the bowstring.

(16) FIG. 4 depicts a process flow for hydrophobizing a bowstring, according to an embodiment of the present disclosure.

(17) At Step 405, a silicone-based hydrophobic coating can be applied to the bowstring. In some cases, the bowstring can be composed of Dacron fibers, Kevlar fibers, Vectran fibers, Spectra fibers, Dyneema fibers, or a combination thereof. In some cases, the silicone-based hydrophobic coating can be composed of silicone nanoparticles, silicone dioxide nanoparticles, or a combination thereof. In some cases, the silicone-based hydrophobic coating can also include a volume of alcohol. In some cases, silicone-based hydrophobic coating can be in spray form. In some cases, the silicone-based hydrophobic coating can be a car coating spray. For example, the silicone-based hydrophobic coating can be ZXL-Rain spray.

(18) At Step 410, the bowstring can be cured for a predefined period of time. In some cases, the predefined period of time can be 10 seconds. In some cases, the predefined period of time can be 1 minute. In some cases, the predefined period of time can be 5 minutes.
