Abstract
A teeth cleaning element containing threading end portions for cleaning relatively large spaces in the teeth consists of from about 400 to about 800 filaments in an elongated bundle that is from about 1,200 to 2,400 about denier. The filaments at the mid-portion of the length of the bundle are textured with the crimps and crinkles of the texturing of the several filaments being intermingled and in contact at numerous points and being adhered together at the contact points to form a bulky, longitudinal, longitudinally and laterally resilient mass. The filaments at the opposite end portions of the bundle that extend from the bulky mid-portion are adhered together in compact, smooth parallel relation.
Claims9
A teeth cleaning element for cleaning relatively large spaces in teeth comprising:
- an elongated bundle from about 400 to about 800 individual filaments in which the filaments in a mid-portion of the length of the bundle are textured by being crimped and crinkled with the crimps and crinkles of the respective filaments being in contact with each other and adhered together at their points of contact, forming a bulky, cohesive, laterally and longitudinally resilient mass of the textured filaments, and in which the filaments in the end portions of the bundle extending outward from the bulky mid-portion are adhered together in compact, smooth, substantially parallel relation, said bundle being of from about 1,200 to about 2,400 denier.
The teeth cleaning element of claim I wherein the filaments are adhered together with a synthetic resin from the group consisting of nylon and polyester.
A teeth cleaning element for cleaning relatively large spaces in teeth comprising:
- an elongated bundle of about 600 individual filaments of a synthetic yarn forming a bundle of about 1,800 denier,
- the filaments in a mid-portion of the length of said bundle being textured by being crimped and crinkled,
- said crimps and crinkles of the respective filaments being in contact with each other and adhered together at their points of contact, forming a bulky, cohesive, laterally and longitudinally resilient mass of the textured filaments, and
- the filaments in the end portions of said bundle extending outward from said bulky mid-portion being adhered together in compact, smooth, substantially parallel relation.
