CENTER OF EXCELLENCE IN NONWOVENS

Spunbond pilot line received new finishing equipment®In March, 2016, STFI's Reicofil 4 pilot line at the spunbond technical centre received new finishing equipment. Parallel to

the already existing foulard, which enables full bath as well as foam impregnation, Kiss-roll finishing equipment with one-sided application system can now also be used. One completely wetted rotation roll touching nonwoven fabric only on the surface enables one-sided minimum application of liquor to the nonwoven. Thus, energy expenditure can be significantly reduced compared to full bath impregnation.

The application roll can rotate both with and opposite to the direction of goods at peripheral speed up to 19 m/min asynchronously to the web speed (max. 300 m/min). Liquor temperature can be set constantly between 15 °C and 80 °C.

This procedure is suitable for hydrophilic applications at very high line speed of up to 1000 meters per minute and is therefore very often installed in industrial spunbond plants. The technical design of this system has the opportunity to use this technology for hydrophobic and oleophobic applications.

With this additional equipment three different variations of chemical application can be offered to customers for examinations and new developments available at STFI's 100 cm wide spunbond pilot line.
