Abstract
Biodegradable strings, for example, for use in racquet sports, fishing line, and trimming line, are described. The biodegradable string includes a petroleum based material and a biodegradable additive blended with the petroleum based material. The petroleum based material may be nylon, polyester, or polyurethane, and the biodegradable additive may be less than 5% of the racquet string by weight. The biodegradable string may include one or more filaments containing the biodegradable additive. The biodegradable string may be of a round, hexagonal, heptagonal, or octagonal shape, and may be capable of withstanding high tension.
Claims
1. A biodegradable racquet string comprising: a petroleum based material; and a biodegradable additive blended with the petroleum based material, wherein the racquet string is biodegradable based on blending of the biodegradable additive with the petroleum based material.
2. The biodegradable racquet string of claim 1, wherein the petroleum based material comprises one of nylon, polyester, or polyurethane.
3. The biodegradable racquet string of claim 1, wherein the biodegradable additive comprises between 0.2 percent and 4 percent of the racquet string by weight.
4. The biodegradable racquet string of claim 1, wherein the racquet string comprises a plurality of filaments.
5. The biodegradable racquet string of claim 4, wherein the plurality of filaments are wound together.
6. The biodegradable racquet string of claim 4, wherein the plurality of filaments are wrapped around one of a center monofdament or a center multifilament.
7. The biodegradable racquet string of claim 4, wherein each filament of the plurality of filaments comprises the petroleum based material and the biodegradable additive.
8. The biodegradable racquet string of claim 4, wherein at least one filament of the plurality of filaments comprises the biodegradable additive.
9. The biodegradable racquet string of claim 1, wherein the racquet string comprises a monofilament.
10. The biodegradable racquet string of claim 1, wherein a cross section of the racquet string has one of a round, hexagonal, heptagonal, or octagonal shape.
AMENDED SHEET (ARTICLE 19)
11. The biodegradable racquet string of claim 1, further comprising at least one color additive.
12. The biodegradable racquet string of claim 1, wherein the racquet string is capable of withstanding at least 120 pounds of tension.
13. The biodegradable racquet string of claim 1, wherein the racquet string is capable of withstanding a knot test of at least 95 pounds of tension.
