Abstract
An application for a substrate for mixing with other ingredients such as water, seeds, fertilizer, wetting agents and dye, to produce Hydroseeding slurry. The substrate includes cardboard (e.g. double-line, Kraft fibers), paper (e.g. recycled newsprint) and a material known as diaper fluff that is created during the production of products such as disposable diapers. The diaper fluff improves moisture retention, improves viscosity and reduces friction, improves coverage.
Claims7
A Hydroseeding substrate comprising:
- up to 99 percent by weight ground cardboard;
- up to 99 percent by weight ground paper;
- and
- at least 1 percent by and less than 10 percent by weight of ground diaper fluff, the ground diaper fluff comprising at least one absorbent selected from the group consisting of cellulose pulp, polyacrylamide, polymers, superabsorbent polymers, copolymers of acrylamide, and polymers;
- said ground cardboard, said ground paper and said ground diaper fluff combined together and constituting a hydroseed substrate are mixed with water and seed to form a hydroseed slurry.
