Abstract
An apparatus for making a nonwoven fabric from thermoplastic fibers has a spinneret for spinning fibers into continuous filaments and a cooler for cooling the filaments. The cooled filaments are then deposited on a conveyor to form a nonwoven web. A first consolidator surface treats the nonwoven web with a hot fluid or hot air as it is conveyed on the conveyor. A second consolidating downstream of the first consolidator has a dual-belt furnace in which the nonwoven web is passed between two circulating belts or continuous belts for surface treating the nonwoven web with a hot fluid or hot air and for applying surface pressure can be applied to the nonwoven web at the same time.
Claims6
An apparatus for making a nonwoven fabric from thermoplastic fibers, the apparatus comprising:
- a spinneret for spinning the fibers as continuous filaments;
- a closed assembly comprising a cooler for cooling the filaments and therebelow a stretcher for stretching the cooled filaments, the closed assembly being so constructed as to exclude from the assembly any further fluid supply or air supply apart from a supply of a cooling fluid to the cooler;
- a conveyor beneath the assembly for receiving the stretched filaments to form a nonwoven web;
- a first consolidator for applying a hot fluid to a surface of the nonwoven web;
- and
- a second consolidator downstream of the first consolidator and comprised of a dual-belt furnace for applying a hot fluid to the surface of the nonwoven web coming from the first consolidator and for applying to the surface of the nonwoven web a pressure with a force greater than 2 Pa.
