The wide slot being cut to be an open angle having a guide slope at the upper slope of the “V”-shape wide slot, and being cut to have many reverse fish scale shapes with a direction opposite to the yarn guiding direction to form the rough surfaces on both sides of the lower slope of the “V”-shape wide slot. The middle-wide slot is located following the wide slot with a width about one fifth to one sixth of said wide slot. The narrow slot is also cut with many reverse fish scale shapes with a direction opposite to the yarn guiding direction to form the rough surfaces on both sides of the v-shape slope of said narrow slot.
