The SynStron yarn was developed by Voith Paper at its R&D center that works exclusively on materials for use in paper machine fabrics. Thisexpertise brings successful products to customers. For example, a paper producer set a record life by using the new SynStron monofilament in a PrintTech-S Q2 dryer fabric from Voith Paper. The fabric ran in the third single-tier dryer group of a paper machine that produced offset and coating base paper at a speed of up to 1,300 m/min.
While the customer had previously changed standard polyester fabrics every 12 months, in contrast the dryer fabric with SynStron monofilaments achieved a fabric life of 446 days (15 months). This is equivalent to an increased life of 30%.
Tests on fabrics that have already run on paper machines include the measurement of remaining seam strength and air permeability. In the case of the fabric mentioned above, the seam strength remained high at 72% of its initial value. This confirms the performance capabilities of fabrics that are made from SynStron. In addition, a contaminant release additive within the monofilament resulted in the used fabric having 76% of the original air permeability. This provided effective performance of the sheet control system and optimal run of the paper web.
