WET NONWOVEN FABRIC FOR PRINTING MACHINE-CLEANING MATERIAL AND ITS PRODUCTION

摘要

PURPOSE: To provide wet nonwoven fabric for cleaning materials, used in machines for automatically cleaning the blankets, impression drums, etc., of printing machines, and a method for producing the same. ;CONSTITUTION: The wet nonwoven fabric for cleaning materials is characterized in that one kind or more of short fibers and thermally fusible fibers and pulp are three-dimensionally interlaced with each other and that the thermally fusible fibers are partially or wholly thermally fused to bond the fibers to each other. And, a method for producing the wet nonwoven fabric for the cleaning materials is characterized by making a blend sheet produced from one kind or more of the short fibers and the thermally fusible fibers and the pulp by a paper-making method collide with water flows to three-dimensionally interlace the blend sheet with the water flows, and subsequently subjecting the interlaced sheet to a thermal treatment to partially or wholly fuse the thermally fusible fibers.;COPYRIGHT: (C)1995,JPO
