INK OCCLUSION MATERIAL FOR WRITING UTENSILS

摘要

The ink occlusion material for writing utensils according to the present invention comprises a fiber bundle of a mixture of an acrylic synthetic fiber and at least one hydrophobic fiber selected from the group consisting of polyester fibers and poly-propylene fibers in a weight ratio of 20 to 70 : 80 to 30. The two fibers are drawn so as to show a sea-island form in the cross section of said fiber bundle and spot-adhered by the partial melt-adhesion of the acrylic synthetic fiber and the fiber bundle is twisted at a rate of 1 to 30 T/M.
