| 摘要 | A method for making a man''s hairpiece comprising a nonwoven network foundation and weighing approximately 6 grams is described. Monofilament nylon strands are molecularly bonded to form a rectangular network which is then shaped and cut to form a foundation. Hair fibers are secured to the bond points in a manner simulating natural growth. | ||||||
| 权利要求 | 1. A method for simultaneously making and styling a hairpiece according to a predetermined hair style, comprising: a. forming a non-woven essentially rectangularly paterned network by steps comprising: spacing a plurality of first filaments essentially parallel to one another in a first plane in a rectangular frame; spacing a plurality of second filaments essentially parallel to one another in a second plane in said frame, said second filaments being essentially perpendicular to and directly above said first filaments, said first and second planes being parallel; and placing said frame in a molecular bonding machine and molecularly bonding said first and second filaments at their intersections to form bond points thereat, said bonding comprising joining said first and second filaments together at their intersections under a temperature of essentially between 400* and 435* Fahrenheit and a pressure of essentially between 53,000 psi and 63,000 psi for no longer than essentially 2 seconds; b. shaping said network to conform to a predetermined head shape; c. cutting said shaped network according to a predetermined pattern to form a foundation; d. securing anchors to said foundation; and e. affixing hair fibers to said foundation according to a predetermined style. 2. The method claimed in claim 1 wherein: said machine is an ultrasonic bonding machine; and said filaments are of extruded monofilament nylon essentially 0.005 inches in diameter. 3. The method claimed in claim 2 wherein shaping said network comprises: tautly connecting said network to hinged arms of a shaping frame, said arms being essentially perpendicular to said shaping frame and movable inwardly thereof; and pressing said network against a heated form having said predetermined head shape until said network assumes said head shape, said arms moving inwardly toward said shaping frame to allow said network to assume said head shape. 4. The method claimed in claim 3 wherein securing said anchors comprises: positioning upper pods and lower pods respectively above and beneath points near the periphery of said foundation, said pods being of vinyl; applying a vinyl solvent adhesive between each pair of upper and lower pods; and squeezing each said pair of pods together to form a solvent bond therebetween. 5. A hairpiece comprising: a non-woven essentially rectangularly patterned network foundation shaped to conform to a predetermined head shape and size comprising a plurality of spaced first filaments essentially parallel to one another, and a plurality of spaced second filaments essentially parallel to one another and essentially perpendicular to and directly above said first filaments, said first and second filaments being molecularly bonded at their intersections; anchor means for securing said hairpiece to the scalp of the user comprising upper pods and lower pods respectively positioned above and beneath points near the periphery of said foundation and secured to one another by a solvent bond, said pods being of vinyl and said solvent being a vinyl solvent adhesive; and a plurality of hair fibers secured to said foundation according to a predetermined style. 6. The hairpiece claimed in claim 5 wherein said filaments are of extruded monofilament nylon essentially 0.005 inches in diameter. |
