METHOD OF AND APPARATUS FOR MAKING A SPUNBOND |
摘要 |
A spunbond web is made by extruding a multiplicity of hot thermoplastic filaments, passing the filaments along an upstream stretch of a path, cooling and stretching the filaments as they move along the upstream stretch of the path, and depositing the cooled and stretched filaments at a downstream end of the upstream stretch on a foraminous belt such that the filaments form a mat thereon. The belt is continuously displaced the belt so as to move the mat downstream along a downstream leg of the path. The mat on the belt, then consolidated with a high-pressure water-jet treatment, and further processed.
