PURPOSE:To obtain the subject ink occlusion unit, capable of promoting synergistic effects of both bonding and twisting, excellent in ink holding and utilization ratio without slipping off, etc., of slivers by forming acrylic fibers and polyester fibers, etc., into the shape of specific slivers, providing a fiber bundle and applying moderate bonding and twisting thereto. CONSTITUTION:The objective ink occluding unit, obtained by blending (A) acrylic synthetic fibers with (B) hydrophobic fibers consisting of the group of polyester and polypropylene fibers at (20-70):(80-30) weight ratio, drawing the resultant blend at (2-6):(2-6) ratio of the number of slivers and providing the fibers (A) and (B) exposed in an island-in-sea form, carrying out dot bonding by partial melt sticking of the fibers (A) and twisting the resultant fiber bundle at 1-30T/M and capable of providing joining between the fibers uniform and stably supplying a liquid ink without causing clogging, etc., of the ink in pores.
