PROCESS FOR PRODUCING ELASTIC AND/OR WATER DEGRADABLE WEBS FROM COMPOSITE FILAMENTS

摘要

A process of manufacturing a non-woven web from virtually endless composite filaments (1). The filaments used in said process are arranged in a sheath-core arrangement in which the sheath component (3) comprise a thermoplastic polymer and the core component (2, 2') is selected from the group of an elastomer, a water-soluble polymer and/or a biodegradable polymer. The sheath component constitutes at least 20 percentage by weight of the filament and that the core component constitutes at least 10 percentage by weight of the filament. The process according to the invention provides a simple and inexpensive process for manufacturing water soluble and/or elastic non-woven webs of any width, using virtually endless filaments.
