Fiber recycling (ropes/woven-non-woven)
Synthetic fiber recycling represents ones of the newest and more interesting opportunities in terms of future developments for the wide range of applications of the recycled product.
Until recently, these materials have not been given their due consideration, because of the low mass to surface ratio, which makes them more difficult to treat compared to other materials. Due to this peculiarity, the decontamination and the drying of these kind of products is often presented as a very complex and anti-economical recycling process.
Thanks to different specific industrial tests that SOREMA has carried out in the past, and its long experience in recycling, SOREMA can once more offer state-of-the-art recycling solutions and specifically designed technologies.
The processes developed by SOREMA allow the treatment of synthetic fibers in a very efficient and economical way.
Fibers of different nature can be treated by SOREMA‘s washing lines, such as Polyamide Polyester and Polypropylene.
Specific hot washing recycling processes can also be properly studied if needed, allowing an excellent decontamination from some of the more complex contaminants (ex.: marine ropes or other similar products).
The difference between woven and non-woven fabrics lies in the way they are produced
The most commonly used fibers are Polypropylene, Polyester, and Polyamide. These fibers have slightly different characteristics, making their use advantageous for different applications. For example, Polypropylene does not absorb water, whereas PA does.. The fibers also have diverse resistance to UV radiation, Polyester being the most resistant and Polypropylene the least resistance. PA is the fiber characterized by having the greatest resistance to stretchability and shrinking, followed by Polyester and then Polypropylene. Another difference is given by the fact that Polypropylene floats, whereas Polyester and PA do not.
