FIELD OF THE INVENTION [0002] Embodiments of the present invention relate generally to the field of textiles, and, more specifically, to water-repellent fabrics. BACKGROUND [0003] Compositions that provide water repellency would help to maintain the durability, operability, and comfort of textiles. However, current compositions face challenges in maintaining water repellency for natural textiles. BRIEF DESCRIPTION OF THE FIGURES [0004] The present disclosure is illustrated by way of example, and not by way of limitation, in the figures of the accompanying drawings, in which: [0005] FIGURE 1 is a flow diagram illustrating a method of treating a textile with a composition in accordance with an embodiment of the present disclosure; [0006] FIGURE 2 is a flow diagram illustrating another method of treating a textile with a composition in accordance with an embodiment of the present disclosure; [0007] FIGURE 3 is a flow diagram illustrating another method of treating a textile with a composition in accordance with an embodiment of the present disclosure; and [0008] FIGURE 4 is a flow diagram illustrating another method of treating a textile with a composition in accordance with an embodiment of the present disclosure. DETAILED DESCRIPTION [0009] The embodiments of the present disclosure relate to compositions that impart desirable properties to textiles. The embodiments also provide a textile that is treated with such a composition, a method for making such composition, and a method of treating a textile with such a composition. [0010] A textile can be treated with an additive that provides a property to the material or increases or improves a property of the textile relative to an analogous textile that has not been treated with a composition described herein. Non-limiting examples of properties provided or increased by the present embodiments include: water resistance; water repellence; hydrophobicity; softness; glide; soil-resistance; resistance to wear during washing/drying; abrasion resistance; and lower curing temperatures. [0011] Textiles can be natural, synthetic, or semi-synthetic. The textiles can be of animal or plant origin, or can be purely synthetic. Non-limiting examples of textiles include fabrics, yarns, knits, fibers, clothing, garments, bedding, domestic linen, and upholstery. A textile can be treated prior with a coloring agent such as a dye or a pigment. Non-limiting examples of natural textiles include: burlap; calico; camel hair; canvas; cashmere; cheesecloth; chiffon; corduroy; cotton; denim; doeskin; double gauze; dowlas; drill; dugget; duck cloth; felt; fishnet; flannel; fleece; foulard; fur; fustian; gabardine; gauze; ghalamkar; haircloth; hemp; herringbone; himroo; hodden; jute; kemp; lace; lawn cloth; leather; textile linen; lensey-woolsey; longcloth; Mackinaw cloth; madapolam; madras; milliskin; mockado; mohair; moire; moleskin; monk's cloth; moquette; mouflon; muslin; natural grosgrain; natural melton; natural mesh; oilskin; organdy; organza; osnaburg; Ottoman; Oxford; paduasoy; polyester; pongee; poplin; quilting; Russel cord; satin; seersucker; sharkskin; silk; single gauze; spandex; suede; terrycloth; triple gauze; tweed; twill; velour; velvet; and wool. In certain embodiments, the textile is chosen from cotton and wool. Non-limiting examples of synthetic textiles include: Dyneema®; Gannex; Gore-Tex™; grosgrain; Kevlar™; synthetic melton; synthetic mesh; microfiber; milliskin; moire; Nomex™; nylon; rayon; silnylon; synthetic grosgrain; synthetic melton; synthetic mesh; and synthetic plush. Non- limiting examples of semi-synthetic textiles include: semi-synthetic grosgrain; semi-synthetic melton; semi-synthetic mesh; and semi-synthetic plush. [0012] A textile could be a blend of natural, synthetic, or semi-synthetic textiles. The following non-limiting examples alternatively describe the ratio of a first textile and a second textile in the blend. The ratio can be: about 20 to about 1; about 19.9 to about 1; about 19.8 to about 1; about 19.7 to about 1; about 19.6 to about 1; about 19.5 to about 1; about 19.4 to about 1; about 19.3 to about 1; about 19.2 to about 1; about 19.1 to about 1; about 19 to about 1; about 18.9 to about 1; about 18.8 to about 1; about 18.7 to about 1; about 18.6 to about 1; about 18.5 to about 1; about 18.4 to about 1; about 18.3 to about 1; about 18.2 to about 1; about 18.1 to about 1; about 18 to about 1; about 17.9 to about 1; about 17.8 to about 1; about 17.7 to about 1; about 17.6 to about 1; about 17.5 to about 1; about 17.4 to about 1; about 17.3 to about 1; about 17.2 to about 1; about 17.1 to about 1; about 17 to about 1; about 16.9 to about 1; about 16.8 to about 1; about 16.7 to about 1; about 16.6 to about 1; about 16.5 to about 1; about 16.4 to about 1; about 16.3 to about 1; about 16.2 to about 1; about 16.1 to about 1; about 16 to about 1; about 15.9 to about 1; about 15.8 to about 1; about 15.7 to about 1; about 15.6 to about 1; about 15.5 to about 1; about 15.4 to about 1; about 15.3 to about 1; about 15.2 to about 1; about 15.1 to about 1; about 15 to about 1; about 14.9 to about 1; about 14.8 to about 1; about 14.7 to about 1; about 14.6 to about 1; about 14.5 to about 1; about 14.4 to about 1; about 14.3 to about 1; about 14.2 to about 1; about 14.1 to about 1; about 14 to about 1; about 13.9 to about 1; about 13.8 to about 1; about 13.7 to about 1; about 13.6 to about 1; about 13.5 to about 1; about 13.4 to about 1; about 13.3 to about 1; about 13.2 to about 1; about 13.1 to about 1; about 13 to about 1; about 12.9 to about 1; about 12.8 to about 1; about 12.7 to about 1; about 12.6 to about 1; about 12.5 to about 1; about 12.4 to about 1; about 12.3 to about 1; about 12.2 to about 1; about 12.1 to about 1; about 12 to about 1; about 11.9 to about 1; about 11.8 to about 1; about 11.7 to about 1; about 11.6 to about 1; about 11.5 to about 1; about 11.4 to about 1; about 11.3 to about 1; about 11.2 to about 1; about 11.1 to about 1; about 11 to about 1; about 10.9 to about 1; about 10.8 to about 1; about 10.7 to about 1; about 10.6 to about 1; about 10.5 to about 1; about 10.4 to about 1; about 10.3 to about 1; about 10.2 to about 1; about 10.1 to about 1; about 10 to about 1; about 9.9 to about 1; about 9.8 to about 1; about 9.7 to about 1; about 9.6 to about 1; about 9.5 to about 1; about 9.4 to about 1; about 9.3 to about 1; about 9.2 to about 1; about 9.1 to about 1; about 9 to about 1; about 8.9 to about 1; about 8.8 to about 1; about 8.7 to about 1; about 8.6 to about 1; about 8.5 to about 1; about 8.4 to about 1; about 8.3 to about
