WIPO Patent Application WO/2007/139097
Kind Code:
A1
Abstract:
This invention provides a polishing roll that can reduce the occurrence of consumption
waste produced upon polishing of an object having a small throughhole such as
a printed wiring board with a throughhole and can reduce clogging of the hole with
consumption waste. The polishing roll (50) comprises a base material formed
of an nonwoven fabric (12) formed by three-dimensionarily crossing synthetic
fibers (14) having a fiber diameter of 10 µm to 36 µm and bonding cross
points among the synthetic fibers (14) with a binder resin (16). The nonwoven
fabric (12) is fixed with a synthetic resin-based adhesive (20) into which abrasive
grains (18) have been dispersed and mixed. The nonwoven polishing material (10)
is shaped into a rectangular form, for example, by cutting, is fixed by compressing,
and is then integrally provided on the outer periphery surface of a core material
(52) with a synthetic resin.
