Claims5
Substantive coatings for monofilament tapes selected from the group consisting of:
- (b) solutions of block copolymers and nonionic surfactant polyethylene glycols in ratios from between about 80:20 and about 20:80;
- (c) melt emulsions of surfactants as the continuous phase and surface energy modifying agents as the discontinuous phase, wherein the ratio of surfactant to surface energy modifying agent is from between about 2:1 and about 4:1;
- and
- (d) inverse melt emulsions of wax as the continuous phase and surfactant as the discontinuous phase, wherein the ratio of wax to surfactant is from between about 99:1 and about 60:40.
Monofilament tapes using a pressure adhesion and loading process comprising a combination of juxtaposition heated rollers at up to about 200° C. with pressures up to 4000 pounds per square inch from said rollers applied to said tape as it passes through said rollers, combined with a gap between said roller less than that of the monofilament tape plus coating, wherein said melt emulsion coating loaded onto both sides of said monofilament tape is thicker than the gap between said heated compression roller.
