MARA WA - 100 % polyester for tarpaulins made with Micro Core Technology® The MCT technology developed by Gütermann, in combination with the water-repellent finish, gives neither water nor moisture a chance. Perfect for tents, tarpaulins, awnings and all laminates that are exposed to downpours and rain showers. Mara WA is the optimum solution for waterproof seams. Conventional core spun threads naturally have thin and thick sections. They consist of fibers that create a hairy appearance and therefore show more abrasion. MCT threads are completely different: they are smoother and more uniform as they consist of filaments that run through the thread in micro loops without interruption. The advantages: A high mechanical load capacity and consistent thread tensions during processing as well as significantly fewer thread breaks. Last but not least, Mara MCT threads are cleaner: as they have no fiber ends, there is practically no abrasion, making MCT threads a guarantee for perfect seams - flawlessly sewable and with an excellent appearance. ' Additional special finish for the permanent liquid and dirt-repellent effect of the sewing thread ' High resistance to care treatments ' Optimum machine safety ' High uniformity, no thick or thin spots ' No fiber fly, no hairiness and no dusting
