Abstract
(EN)
The present invention provides a spunbonded nonwoven fabric with a feel that is easy on the hands (excellent softness). In this spunbonded nonwoven fabric, band-shaped regions of polyethylene glycol (PEG) are formed on the fiber surface layer and the fiber surface layer PEG ratio/fiber average PEG ratio is at least 1.05.
(FR)
La présente invention concerne un tissu non tissé filé-lié ayant une sensation qui est agréable sur les mains (excellente souplesse). Dans ce tissu non tissé filé-lié, des régions en forme de bande de polyéthylèneglycol (PEG) sont formées sur la couche de surface de fibre et le rapport PEG de couche de surface de fibre/rapport PEG moyen de fibre est d'au moins 1,05.
(JA)
本発明は、手に良く馴染む触り心地(優れたソフト感)を有するスパンボンド不織布を提供するものである。本発明のスパンボンド不織布は、繊維表層に帯状のポリエチレングリコール(PEG)領域が形成されており、繊維表層PEG比率/繊維平均PEG比率が1.05以上である。
