Surface modification of ES fibres: the controllability of fold structure and its effect on hydrophilicity

Ethylene-Propylene Side by Side (ES ) fibre remains an important challenge in hydrophilicity. In this study, we obtained folded nonwoven fabrics (FNF) by the through air–bonding process. The fiber with the fold structure was prepared by regulating the treatment temperature, treatment time, and cooling rate. The results showed that the melting point of the shell layer should be controlled at 135°C. The fold structure was most obvious at 135°C,...
