These threads are used in the production of elastic column and big bag carrier column. The properties of these threads are fibrillated and have high strength. T6666 and T9000 type yarns are used as warp threads in the weaving of elastic columns used as conveyor belts in furniture and automotive sectors. T1800 type threads are used as both warp and weft threads in the weaving of big bag carrier columns. These threads provide high column breaking strength which is especially important for big bag manufacturers with their high bearing capacity.
