Abstract:
A method for making a texturized dental floss comprising:(a) coating a texturized yarn in at least a first coating stage with a water-soluble polymer;(b) passing said coated yarn through a unit to remove excess water-soluble polymer coating and to flow the water-soluble polymer into said coated yarn;(c) stretching said coated yarn to reduce the cross-sectional diameter thereof and curing said water-soluble polymer while said coated yarn is under a tension of at least 125% of its relaxed state by the removal of water, the curing of the water-soluble polymer producing a cured texturized yarn having a reduced cross-sectional diameter; and(d) coating said cured texturized yarn in a coating stage after curing the water-soluble polymer with an additional substance to enhance the use of the cured texturized yarn as a floss.
