Abstract

A method for fabricating a toy doll with dreadlock hair is provided. The method comprises preparation of spooled dreadlock hair by twisting and matting synthetic filaments into a cylindrical dreadlock strand, sewing or rooting the dreadlock strand into a toy doll scalp, heat treating the dreadlocks, styling the dreadlocks, and then applying a hair treatment to the dreadlocks. The artisan twists the dreadlocks as they are rooted, thereby increasing their structural integrity. The doll is then heat treated to help set the dreadlocks. The artisan then styles the dreadlocks and applies a hair treatment to protect against wear and facilitate a lifelike appearance.

Claims (12)

1. A method of fabricating a doll with dreadlock hair, said method comprising the steps of:

twisting at least one hair filament to create a hair lock,

sewing multiple hair locks into a doll scalp using a doll hair rooting machine, wherein each hair lock comprises a root end and a cut end,

styling said hair locks into a predetermined hairstyle; and

applying a hair constraint around said doll scalp and hair locks, and heating said hair locks within a predetermined temperature range for a predetermined amount of time.

2. The method of claim 1 , wherein each said hair lock comprises more than one filament of synthetic polymer twisted together to form an elongated cylindrical shape.

3. The method of claim 1 , wherein said hair locks are heated at a temperature of 150 degrees Fahrenheit up to 200 degrees Fahrenheit.

6. The method of claim 1 , wherein said hair constraint comprises a polyethylene polymer.

7. The method of claim 1 , further comprising the steps of allowing said hair locks to cool after said heating, and applying hair treatment to said hair locks from said root end to said cut end after said hair locks are cooled.

8. The method of claim 7 , wherein said hair treatment is applied to said cut end of said hair locks after said hair locks are styled.
