Title:
SPECTACLE-LENS-HOLDING BAND AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2011102905
Kind Code:
A
Abstract:
To provide a spectacle-lens-holding band that has high strength and excellent durability and is satisfactory in lens holdability and attaching workability, and to provide a method for manufacturing the same.
The band for holding a spectacle lens from its peripheral edge is formed from a fluororesin monofilament. In this band, the elastic recovery factor of the band 20% extended to be measured based on the requirements in JIS L1013-1999 is 80% or more, a boiled-water shrinkage is 2 to 6%, and a tensile strength is 0.4 to 1.2 GPa.
