Title: Friction material and non-slip glove using material
Inventor: FUJII KEIICHI
IPC: B24D15/04
Filed: 1988-02-25
Abstract: PURPOSE:To effectively utilize aquatic resources as a non-slip material for sports and work which is liable to be wetted by water by forming a friction portion using a friction material in which the outer layer of the skin of a specific aquatic fish is formed into a friction face. CONSTITUTION:A friction material is formed with the outer layer of the skin ot aquatic fish 'filefish' which has a group of thickly grown needle-like projections 1 as the friction face. When this group of projections is dry, it gives physically effective friction and bas high friction coefficient, and a non-slip glove in which friction portion 2 is formed with the friction material, i.e., with this material gives an excellent non-slip performance. When turning to a wetted condition, the group of needle-like small projections 1 absorbs water and gets thicker with its end getting sharper, to be restored just like the living time of the filefish in water, further improving the physical friction coefficient. Hence, even with the existence of water which function as a lubricating material, the non-slip effect thereof can be further enhanced.
