DREF 2000 friction spinning machine
DREF 2000 friction-spun yarns are used in filter cartridges for liquid filtration. Discuss the fibre material, yarn construction and intended service conditions with DREF before specifying a filtration application.
Filter performance, service life and production costs depend on the material, manufacturing process and operating conditions. Confirm the required filtration rating and any food-contact requirements through application-specific testing and documentation.
DREF 2000 ADVANTAGES
- System flexibility and simplicity
- Production of both ‘S’ and ‘Z’ yarns at any time without mechanical alterations to the machine
- Expansion of the scope of yarn and fibre utilization in the medium yarn count range
- Reduced yarn preparation costs due to high sliver weights (card slivers)
- Dust extraction for secondary fibres
- Touch Screen: – allows the easy handling of the various yarn parameters – yarn count calculation, length and weight measurement are included by means of the PLC control – link to the customer’s computer is possible by means of an interface
- High spinning speeds
- High Bobbin weights
- Low energy costs due to the use of only 1 fan for 12 spinning heads
- Simple, variable and single adjustment of the negative pressure for all spinning heads.
- Feeding of all types of filaments, yarns and components as yarn cores, in order to attain high yarn strength and production speeds, voluminous yarns and specific product characteristics
DREF 2000 APPLICATION
