[0046] (1) The high-speed airflow is used to continuously blow the long yarn bundles of functional fibers through the high-speed airflow expander, and each single yarn is fully separated by controlling the airflow speed and blowing direction of the expander to form a bulky or spiral continuous fiber tow .
[0047] (2) By adjusting the blowing speed and blowing angle, two basic types of bulked yarn can be made, namely bulky and spiral. By adjusting and changing the air flow into the air vents, the preparation of bulked yarns of different specifications can be realized; by designing the angle of the air guides to vary between 15° and 75°, puffers with different angles can be processed for selection. Preferably, the preparation of bulky and spiral bulked yarns can be realized.
[0048] (3) Through transverse stretching, the continuous fiber bundle is dispersed and extended in the transverse direction, so that the continuous fiber bundle is dispersed and thinned and widened while main...
