NON-WOVEN FABRIC HAVING SPECIFIC OPENING PATTERN AND PRODUCTION THEREOF

摘要

PURPOSE:To provide the subject non-woven fabric having excellent filth- wiping-out ability and capable of being used as a substitute for woven fabric by arranging opening having a specific dimension regularly between non-opened portions in such a grid state to divide the non-opened portions in both the longitudinal and lateral directions. CONSTITUTION:Openings 1 having a size of 0.2-1.5mm are arranged so as to form longitudinal rows 3 and lateral rows 4 at longitudinally and laterally independent intervals (approximately 1.2-3 times the size of the opening) and at approximately equal intervals. The rows of the openings each independently surround non-opening portions 2 at approximately equal intervals every 2-9 openings to form a grid pattern. The rows forming the grid may be one row such as the row 4 or plural rows such as the longitudinal row 3.
