FILM NONWOVEN LAMINATED MATERIAL AND ARTICLES Russian patent published in 2000 - IPC

Abstract RU 2150390 C1

FIELD: film nonwoven laminated materials. SUBSTANCE: film nonwoven laminated material includes film layer oriented in direction longitudinal to machine, and arranged in layers on layer of base of nonwoven material with small thickness. Separate layers are formed so that film layer in laminated state has elongation at rupture load value in direction across machine which exceeds elongation at value of peak load for layer of nonwoven material in the same direction. If laminated material is subjected to large tensioning forces in direction across machine, layer of nonwoven material will be damaged earlier than film layer. Laminated material has value of peak load at least 300 g. Laminated material is very useful, for instance, as material of external bandage for hygienic absorbing articles. EFFECT: higher efficiency. 17 cl, 3 dwg, 4 ex
