Abstract
Object of the invention is a voluminous filament yarn of three-dimensionally curled filaments without loops, coils or whorls having a positive value of residual crimp c.sub.3, with several loose filament ends sticking out and at least said ends having a flex abrasion resistance of less than about 1500 cycles. The obtained yarn excels in the uniformity of its characteristics all over the yarn length, its high crimp elongation and recovery from stretch and can be worked up to fabrics having an extremely low tendency to pilling.
