PURPOSE:To obtain a fasciated spun yarn having large hot-water shrinkage, by increasing the sliver-clamping pressure of an apron of a drafting part and decreasing the delivery roller speed of the twisting part after the drafting part. CONSTITUTION:The spanning frame of the present process has an air-jet twisting nozzle 2 and a delivery roller 3 at the downstream of a three-wire drafting apparatus 1 having an apron. The sliver clamping pressure of the aprons 8t, 8b of the drafting apparatus 1 is increased to draw each fiber of the sliver S between the middle rollers 6t, 6b and front rollers 7t, 7b and the drawn sliver is delivered to the air-ejection nozzle 2. The peripheral speed of the delivery roller 3 is made smaller than that of the front rollers 7t, 7b to decrease the tension in the twisting zone. |
