HYDROENTANGLED ELASTIC NONWOVEN SHEET |
摘要 |
A method for making an elastic fabric with the steps of providing a hydroentangled precursor fabric having at least 1% by weight of binder fibers, heating the precursor fabric to a temperature above the melting point of the binder fibers and then drawing the precursor fabric in the machine direction at a ratio sufficient to reduce the width by more than 20% and at a strain rate of 10 to 800% per minute to produce an elastic fabric having a cross-directional extensibility of about 100% up to 500% and a 30-95% recovery under a 50% extension. |
