<p>PURPOSE:To provide a fluid-pressed-in-nozzle improved in the operatability thereof by reducing the hunting of a fiber at a staying-starting point and smoothly transferring the lump of the stayed fiber in a compression chamber. CONSTITUTION:In a fluid-pressed-in-nozzle constituted successively of a heated fluid-spraying nozzle 10, a compression chamber 20 having plural blades 21 disposed radially, and a staying time-controlling chamber 30 for flowing a cooling fluid in the direction counter to the spraying direction of the heated fluid, the inclination angles of the blades 21 are controlled to the three stages consisting of the upper part of >=1.1 degree, the middle part of <1.0 degree, and the lover part of >=1.1 degree.</p> |
