Abstract
(EN) Disclosed are a nonwoven fabric, a nonwoven fabric laminate, and an article. The disclosed nonwoven fabric has a sieve function value of 2.0-65.9% as expressed by Equation 1. Equation 1: Sieve function value (%) = (final weight of powder remaining on nonwoven fabric after sieving test)/(initial weight of powder used for sieving test) × 100
(FR) L'invention concerne un tissu non tissé, un stratifié de tissu non tissé et un article. Le tissu non tissé selon l'invention a une valeur de fonction de tamis de 2,0-65,9 % telle qu'exprimée par l'équation 1. Équation 1: Valeur de fonction de tamis (%) = (poids final de poudre restant sur un tissu non tissé après essai de tamisage)/ (poids initial de poudre utilisé pour le test de tamisage) × 100
(KO) 부직포, 부직포 적층체 및 물품이 개시된다. 개시된 부직포는 하기 수학식 1로 표시되는 시브 함수값이 2.0~65.9%이다: [수학식 1] 시브 함수값(%) = (시빙 시험 후 부직포 위에 남아 있는 분말의 최종 중량)/(시빙 시험에 사용된 분말의 초기 중량) × 100.
