Safe and dust-free nonwoven
Dust and loose fibers in nonwoven products are unacceptable: medical gowns, surgical drapes, mouth-masks, covers, and wound-dressings have to be completely dust-free. But because nonwoven substrates consist of fibers, eliminating dust and loose fibers is challenging. However, effective web cleaning removes fibers and optimizes your nonwoven quality without hindering production.
Nonwoven manufacturing methods
Nonwovens are manufactured by putting fibers of filaments together in the form of a web (similar to paper on a paper machine) and then binding them either mechanically or thermally.
- Mechanic nonwoven production is similar to felt manufacturing. The process interlocks fibers with serrated needles, so that the inter-fiber friction results in a stronger fabric, with an adhesive or chemical binder.
- Thermal nonwoven production works by applying a binder and melting it onto the web by increasing temperature.
Due to the construction of the substrate, there are some significant dust sources when converting these webs.
Specifically, the unwind generates a large volume of dust and loose fibers, as a layer of nonwoven that is pulled away from the core releases a lot of debris.
Removing dust and fibers in nonwoven production
Almost all nonwoven applications need to be dust-free. For instance, nonwoven used in medical protection materials like face masks needs to be perfectly clean and particle-free.
In nonwoven filters for air or fluids, such as water or coffee filters and tea-bags, dust and fibers are a significant concern. Even in diaper stock and feminine hygiene products, the absence of loose particles is a clear indication of quality.
How nonwoven web cleaning eliminates dust without production interruptions
In several stages of nonwoven production and converting, effective web cleaning is vital to reach quality and hygiene standards.
Directly after the unwind station, Weducon HE9o nonwoven web cleaner catches debris. Cleaning at this spot prevents dust from getting airborne and contaminating the production lines. After slitting and needle punching or felting, it removes dust and fibers immediately.
Particular measurements in the design of the Weducon HE 90 nonwoven cleaner make it the high-quality web cleaning solution nonwoven manufacturing needs. Because continuous nonwoven processes need a web cleaning solution that prevents production interruptions and guarantees constant high-level cleaning.
