New Material in Forming Fabrics leads to Reduced Power Cosumption and Increased Lifetime

摘要

Currently, the most common material combination in use for the machineside wefts (CMD) in forming fabric designs is polyester and poly amide. The main advantages and disadvantages of these materials are described in Figure 1.Forming fabric manufacturers have looked to improve the abrasion resistance of forming fabrics by increasing the amount of polyamide on the machineside. Whilst this approach addresses the abrasion resistance the negative aspect is a (potential) increase in power consumption due to the increased coefficient of friction of polyamide compared to polyester, see Figure 4. Additionally, an increase in edge curl as well as a decrease in fabric dimensional stability is likely, caused by the high moisture uptake of polyamide.
