FIELD: equipment for manufacture of web of non-woven material from single thermoplastic filaments.
SUBSTANCE: apparatus has spinneret, cooling chamber, pulling unit, and unit for laying of filaments for producing of web. Two or more polymer melts may be fed to spinneret. Apparatus is further provided with device for feeding of various polymer melts so that bicomponent or multiple-component filaments are delivered through spinneret opening. Cooling chamber is divided into at least two sections where bicomponent or multiple-component filaments are brought into contact with process air at different convective heat discharge capacity.
EFFECT: increased efficiency in directed adjustment of filaments properties and, accordingly, characteristics of non-woven materials produced.
