Freudenberg nonwovens india supplies non-woven bags. Binder-free polyester non-woven are an inexpensive alternative to traditional needle-felt products. With its viledon sine bags, freudenberg non-woven has adopted a fresh approach. The performance capability of these innovative filtering bags is attributable to their smooth surface. This prevents particles being deposited and thus impairing the filtration effect. Filter soiling proceeds much more slowly and the cleaning cycles can be extended with concomitantly fewer production stoppages and reduced cleaning costs as well. The polyester non-woven excels not only in terms of cost-efficient operation, but also of high filtering efficacy: even fine dusts are retained. The emission values remain below 1 mg/m3. The viledon sine bags thus approach the performance capabilities of ptfe membranes. Depending on the requirements involved, much of the re-usable raw materials can be recovered to a large degree. When required, the filtration process can be extended to incorporate static filters, so as to achieve an even higher level of air purity - in contrast to needle-felt products, where because of the lesser filtering effect, efficient use of static filters will usually be a non-viable option.
