FET-100 Extrusion

Central to all FET laboratory and pilot melt spinning systems is the specially developed extrusion module, the FET-100 Extrusion which allows multiple process options. This extrusion module is designed to provide melt spinning capacity to any one of the three downstream process options. The module is mounted on a hydraulic lifting table which permits automated adjustment of the working height.

FET-101 Multifilament

FET offers a wide range of bespoke pilot and laboratory melt spinning systems for continuous multifilament applications capable of matching the demands of all users. Each variation of the FET-101 Multifilament option is uniquely specified and designed for world leading companies and research institutes for a wide variety of applications.

 

FET-102 Nonwoven

Simple integration of the FET-102 Nonwoven option gives the possibility of melt spinning nonwoven materials. Melt blown and spun bond types can both be achieved on the same base system. This is applicable to a broad range of polymers, including viscous materials normally not appropriate for the melt blowing or spun bond process. Applications include resorbable biomedical polymers and engineering grade materials.

 

FET-103 Monofilament

Utilising the same extrusion module, FET can also provide specialist laboratory and pilot melt spinning systems for monofilament applications, the FET-100 monofilament. As with multifilament equipment, our flexible monofilament systems are being used by high tech organisations and research institutes on a variety of technical and R&D projects.

A significant development is that FET-100 systems can be specified to be multi-functional, allowing for easy and fast conversion between material formats. It configures to all combinations of multifilament, monofilament and melt spinning of nonwoven structures as required.

This highly versatile and flexible system is ideal for research and development, designed specifically for detailed investigation into extruded textile materials. Benefits include substantial savings on cost, floor space and also the ability to add optional equipment in the future.

MELT SPINNING SYSTEMS FOR NON-WOVEN STRUCTURES

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.

Process applications

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:

  • Those required for filtration applications

  • Bio-medical applications using resorbable polymers

  • Structures which exploit polymer properties such as thermal and chemical resistance

Along with:

  • 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.

LABORATORY SCALE WET SPINNING SYSTEMS INTRODUCING THE FET-200 LAB

In addition to pilot and small scale wet spinning production lines, FET now also designs and manufactures a lab scale version which is more suitable for the early stages of formulation and process development.

Systems can be supplied for a wide range of different fibre types. These have ranged from corrosive aqueous salt solutions (such as alginate fibres), to acidic systems (such as engineered silk) and also systems using flammable, toxic solvents (such as UHMWPE).

The FET-200 LAB system is ideal for formulation and process development:

  • Compact design makes efficient use of laboratory space whilst delivering high level of functionality

  • Enables accurate replication of processes on a small scale

  • Allows full exploration of processes with low volumes of processing solutions

  • Capable of processing wide range of materials: e.g. corrosive, flammable, acidic
