Abstract

Spun bond is made by collecting thermoplastic filaments on a perforated surface and the spun bon is then subjected to hydrodynamic consolidation with high-pressure water jets. The filaments before the formation of the spun bond or after the formation of the spun bond are treated with a wetting agent prior to the hydrodynamic consolidation.

Claims (7)

1. A method of making a spun-bond web comprising the steps of:
(a) forming filaments of thermoplastics synthetic resin;
(b) collecting said filaments in a spun-bond web;
(c) treating said filaments with a wetting agent; and (d) hydrodynamically consolidating said spun-bond web.
2. The method defined in claim 1 wherein said filaments are produced with a spinnerette and are then cooled.
3. The method defined in claim 2 wherein said filaments are collected on a continuously moved foraminous belt.
4. The method defined in claim 3, further comprising comprising drawing air through said belt from below said belt in a region at which sand filaments are collected on said belt with at least one suction device.
5. The method defined in claim 4 wherein said filaments are treated with said wetting agent after the filaments have been collected into a spun-bond on said bel.
6. The method defined in claim 5 wherein said wetting agent is a surfactant.
7. The method defined in claim 6 wherein said spun-bond web is hydrodynamically consolidated by training water jets thereon.
