| 摘要 | This invention relates to a process for squeezing and/or drying a humid thread, particularly a textile thread, in the course of a treatment, such as dyeing, effected continuously on said thread during the rectilinear displacement thereof, wherein the humid thread is passed into a zone traversed by a current of air at a pressure much lower than the pressure prevailing about the thread during the operation having provoked its humidification. The invention also relates to an apparatus for continuously treating a thread, for example a textile thread, applying the process as described hereinabove. | ||||||
| 权利要求 | 1. Apparatus for the continuous treatment of a thread during the rectilinear displacement therethrough which comprises: at least one liquid treatment chamber having inlet and outlet means dimensioned to closely receive said thread; conduit means connecting said liquid treatment chamber to a source of treatment liquid; at least one gas treatment chamber having inlet and outlet means adapted to receive said thread, said inlet and outlet means comprising convergent-divergent nozzles arranged in alignment with said inlet and outlet means of said liquid treatment chamber; conduit means connecting said gas treatment chamber to a source of compressed inert gas; said liquid treatment chamber and said gas treatment chamber being interconnected by a recovery chamber; and conduit means connected to said recovery chamber and adapted to remove liquid therefrom. 2. Apparatus for the continuous treatment of a thread during the rectilinear displacement therethrough which comprises: a plurality of alternating aligned liquid treatment chambers and gas treatment chambers, each of said chambers being interconnected by a recovery chamber; said liquid treatment chambers having inlet and outlet means for displacement of said thread therethrough and supply means adapted to supply a treatment liquid thereto; said gas treatment chambers having inlet and outlet means comprising convergent-divergent nozzles through which said thread passes and further including supply means connected to a common manifold for supplying compressed inert gas thereto; and said recovery chambers including conduit means adapted to recover excess treatment liquid therefrom. 3. Apparatus according to claim 1 wherein said inlet and outlet means of said liquid treatment chamber comprises capillary tubes. 4. Apparatus according to claim 1 wherein the outlet means of the last gas treatment chamber in the direction of thread displacement comprises a recovery chamber including means for supply compressed inert gas thereto and a recovery conduit disposed at an angle of about 45* from the direction of thread movement. 5. Apparatus according to claim 1 which further includes heating means disposed in alignment with said outlet means of the last recovery chamber in the direction of thread displacement. 6. Apparatus according to claim 5 wherein said heating means comprises a capillary tube disposed in alignment with said recovery chamber and adapted for thread movement therethrough; and insulating means surroUnding said tube having electrically activated heating resistors embedded therein. 7. Apparatus according to claim 1 wherein at least one of said liquid treatment chambers is provided with heating means. 8. Apparatus according to claim 1 wherein said conduit means connecting said gas treatment chamber to a source of compressed inert gas includes auxiliary conduit means connected thereto, said auxiliary conduit means being adapted to provide compressed gas at a pressure higher than the compressed gas normally provided in said conduit means, and including means for selectively supplying said higher pressure compressed gas to said conduit means. 9. Apparatus according to claim 8 wherein said means for selectively supplying said higher pressure compressed gas to said conduit means comprises a fluid controlled binary trigger circuit. 10. Apparatus according to claim 1 wherein said conduit means connecting said gas treatment chamber to a source of compressed inert gas includes an auxiliary conduit having a generator of sonic or supersonic vibrations mounted therein. 11. Apparatus according to claim 1 wherein said recovery chamber which is preceded by a gas treatment chamber in the direction of thread displacement, includes means for selectively communicating the interior thereof with the atmosphere. 12. Apparatus according to claim 11 wherein said selective communicating means comprises a vibrating reed whistle. |
