Abstract
A non-woven abrasive material including a lofty, open, three dimensional web of non-woven fibers randomly intertwined and carrying abrasive particles and a binder material bonding the fibers together and bonding the abrasive particles to the fibers, with hydrogenated vegetable oil in solid form coating the fibers, particles and binder material at the surface of the web and within voids in the interior of the web, and preferably also with a coating of resinous plastic binder encapsulating the hydrogenated vegetable oil at the surface of the web and within its interior.
Claims26
A non-woven abrasive material comprising:
- a lofty, open, three dimensional web of non-woven fibers randomly intertwined;
- abrasive particles carried by said web with at least some of the particles distributed within the interior of the web;
- binder material in the web bonding said fibers together and bonding said abrasive particles to the fibers;
- said web containing voids constituting a substantial portion of the volume of the three dimensional web;
- and
- hydrogenated vegetable oil in solid form coating said fibers, particles and binder material at the surface of the web and within said voids.
The method that comprises:
- applying hydrogenated vegetable oil to a lofty, open, three dimensional web of non-woven fibers carrying abrasive particles at least some of which are distributed within the interior of the web, with binder material bonding said fibers together and bonding said particles to the fibers;
- flowing some of said hydrogenated vegetable oil in melted form into voids within said web;
- and
- cooling said hydrogenated vegetable oil to solid form coating said fibers, particles and binder material at the surface of the web and within said voids.
The method that comprises:
- applying hydrogenated vegetable oil in granular solid form to a surface of a lofty, open, three dimensional web of non-woven fibers carrying abrasive particles at least some of which are distributed within the interior of the web, with binder material bonding said fibers together and bonding said abrasive particles to the fibers;
- heating said granular hydrogenated vegetable oil to melting temperature and thereby converting it to liquid form;
- flowing some of said melted hydrogenated vegetable oil into voids within said web;
- and
- cooling said hydrogenated vegetable oil to solid form coating said fibers, particles and binder material at the surface of the web and within said voids.
The method that comprises:
- applying hydrogenated vegetable oil in granular solid form to the upper surface of a lofty, open, three dimensional web of non-woven fibers carrying abrasive particles at least some of which are distributed within the interior of the web, with binder material bonding said fibers together and bonding said abrasive particles to the fibers;
- heating said granular hydrogenated vegetable oil to melting temperature and thereby converting it to liquid form;
- flowing some of said melted hydrogenated vegetable oil downwardly by gravity into voids within said web;
- and
- cooling said hydrogenated vegetable oil to solid form coating said fibers, particles and binder material at the upper surface of the web and within said voids.
