Title:
MANUFACTURING METHOD OF FELT FOR PAPERMAKING AND FELT FOR PAPERMAKING MANUFACTURED BY THE SAME
Document Type and Number:
Japanese Patent JP2022113506
Kind Code:
A
Abstract:
To provide a manufacturing method of a felt for papermaking, which suppresses increase of bending rigidity in a weft direction and is excellent in resistance to hair removal, and a felt for papermaking manufactured by the manufacturing method.SOLUTION: A felt for papermaking that has a base cloth and a surface batt fiber layer that is laminated on a papermaking surface side of the base cloth, contains a core-sheath fiber having a fusion point of a sheath component of 165 to 185°C and higher a fusion point of a core component than that of the sheath component, and has fineness of 15 to 20 dtex. A manufacturing method of the felt for papermaking has a laminating step to obtain a laminate by entangling a base cloth material with a surface batt fiber layer material, and a compression treatment step to apply compression treatment to the laminate at a temperature higher than the fusion point of the sheath component of the core-sheath fiber by 0 to 10°C. When entire mass of the surface batt fiber layer is 100%, preferably 30 to 50% by mass of the core-sheath fiber is contained. The felt for papermaking is manufactured by the manufacturing method of the felt for papermaking.SELECTED DRAWING: Figure 8
