Developments in the manufacture of non-wovens
As a result of innovative development work by FET, non-woven structures can now be readily made from “difficult to process” polymers. The new processing technology is a unique adaptation of the melt blowing process and makes possible the conversion of a wide range of polymers into non-woven webs, using a single processing stage. For many of our clients, the benefits of single stage manufacturing and the flexibility provided solve many processing problems and give them a substantial competitive edge.
New process have been developed in particular for polymers that have properties which would in normal circumstances make them unsuitable for melt blowing, such as high melt viscosity or susceptibility to degradation. These versatile systems enable the extrusion of melt blown nonwovens with a broad span of structures and mechanical properties, such as:
- Simpler processing route than other techniques such as needle felts
- There are numerous options for post processing of the web, by calendaring, point bonding or lamination
Equipment for melt spun fibres and yarns can be tailored to precise client requirements and are also available for small batch production, pilot and laboratory applications.
