Claims
- 1. A method for manufacturing monofilament string trimmer line including the steps of:
- supplying plastic to an extruder for producing an extruded monofilament plastic line;
- placing said extruded monofilament plastic line in a moisturizing agent for a time period between four and forty-eight hours so that said line absorbs moisturizing agent in an amount up to eleven percent by weight of said line; and
- packaging said line in a sealed package to retain the moisture content of said line.
- 2. The method according to claim 1 wherein said moisturizing agent comprises water, and wherein the step of placing said line in a moisturizing agent comprises immersing said line in water for a predetermined period of time.
- 3. The method according to claim 2 wherein said line comprises monofilament nylon line.
- 4. The method according to claim 1 wherein said moisturizing agent contains monomeric amides.
- 5. The method according to claim 4 wherein said line comprises monofilament nylon line.
- 6. A method for manufacturing monofilament string trimmer line including the steps of:
- supplying plastic to an extruder for producing an extruded monofilament plastic line;
- placing said extruded monofilament plastic line in a moisturizing agent until the line absorbs moisturizing agent in an amount up to eleven percent by weight of said line;
- adding a color indicator to said line causing said line to have one color when said moisturizing agent content thereof is below a first predetermined percentage and to have another color when said moisturizing agent content is above a second predetermined percentage; and
- packaging said line in a sealed package.
- 7. The method according to claim 6 wherein said moisturizing agent comprises water, and wherein the step of placing said line in a moisturizing agent comprises immersing said line in water for a predetermined period of time.
- 8. The method according claim 7 wherein said step of immersing said line in a moisturizing agent comprises immersing said line in water, and said color indicator is a salt dissolved in said water.
- 9. The method according to claim 8 wherein said salt is selected from the class of copper chloride and cobalt chloride.
- 10. A method for manufacturing monofilament string trimmer line including the steps of:
- supplying plastic to an extruder for producing an extruded monofilament plastic line;
- placing said extruded monofilament plastic line in a moisturizing agent until the line absorbs moisturizing agent in an amount up to eleven percent by weight of said line;
- coating said line with a moisture-indicating, color-changing material; and
- packaging said line in a sealed package.
- 11. The method according to claim 10 wherein the moisture-inducing color-changing material is in the form of a salt selected from the class of copper chloride and cobalt chloride.
