Air jet flow type apparatus and method for treating textile material

An air jet flow type apparatus for treating textile fabric in rope form, comprising a fabric treating passageway in circular form which is composed of a transferring passageway intended to transfer the textile fabric in rope form and a residence chamber intended to transfer the textile fabric in zigzag form, both ends of which are jointed to one another, and carrying out dyeing and other treatment with jetting force of a treating mixed fluid which is composed of jet air flow and liquor flow jetted from the treating fluid jetting section while transferring and circulating the charged fabric from the transferring passageway to the residence chamber and re-transferring from the residence chamber to the transferring passageway, characterized in that a nozzle case is equipped via a flange so as to compose a part of the transferring passageway, the nozzle case is partitioned with a partition flange which is internally provided at the center point of the case, and is provided with an air feed pipeline which communicates with the air jetting portion and a liquor feed pipeline which communicates with the liquor jetting portion, a sliding tube having a convexed ring-form taper surface (a) at the end part of the air jetting portion and a concaved ring-form taper surface (b) at the end part of the liquor jetting section is provided so as to slide freely through the partition flange of the nozzle case, a tubular guide having a concaved ring-form taper surface (a) so as to form a nozzle (a) corresponding to the taper surface (a) of the sliding tube is provided at one end of the nozzle case, a trumpet-shaped guide having at its one end a convexed ring-form taper surface (b) so as to form a nozzle (b) corresponding to the taper surface (b) of the sliding tube and having its other end acting as a fabric guide is provided at other end of the nozzle case, and either one or both of the tubular guide and trumpet-shaped guide can slidable and the clearance in the nozzle (a) and nozzle (b) is adjustable respectively.

An air jet flow type apparatus for treating textile fabric in rope form, comprising a circular fabric treating passageway which is composed of a transferring passageway intended to transfer the textile fabric in rope form and a residence chamber intended to transfer the textile fabric in zigzag form, both ends of which are jointed to one another, the transferring passageway which is provided, at its inlet portion in approximately vertical position, with a treating fluid jetting section and the passageway bends in direction to horizontal position and extends in an approximately straight form, the residence chamber having a slope section which gradually inclines downward in direction from the entrance section of the chamber to the advancing direction of the textile fabric and having an exit section of spherical shape which bends upward and having a porous perforated plate which composes a dual bottom of the residence chamber, a treating liquor circulation conduit which feeds treating liquor via a pump and a heat exchanger from an liquid accumulating portion being equipped under the bottom of the residence chamber, an air circulation conduit which feeds air from a gaseous phase area of the residence chamber through a blower, and carrying out dyeing and other treatment with jetting force of air and liquor mixed fluid jetted from the treating fluid jetting section while transferring and circulating the charged fabric from the transferring passageway to the residence chamber and re-transferring from the residence chamber to the transferring passageway, characterized in that the apparatus is equipped with a high temperature liquid drain valve connected to the residence chamber, a pressure sensor intended to detect internal pressure of the apparatus, a pressure control valve for cooling control connected to the apparatus, and a control unit intended to control the high temperature liquid drain valve and pressure control valve for cooling control.

A method for treating a textile fabric in rope form in an air jet flow type, comprising charging the textile fabric in a circular fabric treating passageway comprised of a transferring passageway and a residence chamber both ends of which are jointed to one another, and carrying out dyeing and other treatment to the charged textile fabric while transferring the textile fabric from the transferring passageway to the residence chamber, but in zigzag form in the residence chamber, with jetting force of air and liquor mixed fluid which is jetted from the treating fluid jetting section having an air jetting portion and a liquor jetting portion and while re-circulating the fabric to the transferring passageway from the residence chamber with jetting force of the fluid, characterized in that the exit section of the residence chamber is located at a position lower than the entrance section thereof to thereby allow the treating liquor jetting portion at the inlet of the transferring passageway to locate at low position, the textile fabric is taken up at a short distance into the transferring passageway from the residence chamber with jetting force of the treating fluid which is jetted from the treating fluid jetting section and wetted with the treating liquor while being circulatingly transferred and, thereafter, the textile fabric moves down gradually in its advancing direction from the entrance section of the residence chamber, and dyeing and other treatment for feeling, etc. are applied to the textile fabric while being transferred in zigzag form as if floating, with separation of the treating liquor from the textile fabric by the dual bottom of the residence chamber, thereafter being again taken up in direction to the treating fluid jetting section for re-circulating.
