SUPERLIGHT NONWOVEN MATERIAL SUITABLE FOR REPROCESSING INTO ARTICLE Russian patent published in 2003 - IPC

FIELD: textile industry. SUBSTANCE: superlight material comprises nonwoven web of fibrous structure composed of separate fibers or filaments. Weight of basic portion of material is less than 13.5 g/sq.m. Pattern of connected zones is formed on surface of basic portion of material. Web has dimensional stability characterized by factor calculated by multiplying Puasson coefficient of nonwoven material at 10% elongation in direction of advancement of semi-finished product in machine for reprocessing it into article by basic weight of nonwoven web, with said factor being equal to 40.5 g/sq. m. Two other versions of nonwoven material are characterized by different methods of manufacture of web surface pattern: according to one version, pattern on web surface is made in the form of continuously connected zones and, according to other version, pattern is made in the form of zones connected along intermitted lines. Article for individual care comprises said nonwoven material used as facing. Method involves providing nonwoven material of fibrous structure comprising disconnected separate fibers or filaments with basic weight of 23.5 g/sq.m; forming connected zone pattern on material web surface for providing dimensional stability. EFFECT: improved quality of nonwoven superlight material and wider range of articles produced from such materials. 28 cl, 11 dwg, 13 tbl
