Abstract

A dyeing device adapted to move in a high pressure space having a fluid is provided. The dyeing device includes a magnetic dyeing shaft and a dye mixing chamber connected to the magnetic dyeing shaft. The magnetic dyeing shaft is configured to make a fiber product wind thereon, and the dye mixing chamber is configured to store dye, and the dye mixing chamber is adapted to let the fluid in the high pressure space flow through. A dyeing apparatus including the dyeing device is also provided.

First claim

What is claimed is:

1 . A dyeing device configured to move in a high pressure space, comprising:
a magnetic dyeing shaft configured to be wrapped by a fiber product thereon; and a dye mixing chamber connected to the magnetic dyeing shaft and configured to store a dye, and the dye mixing chamber allowing a fluid in the high pressure space to flow through.

2 . The dyeing device according to claim 1 , wherein the dye mixing chamber comprises:
a chamber configured to store the dye therein; and at least one first through hole which connects the chamber with the high pressure space to allow the fluid to flow in and out of the chamber.

3 . The dyeing device according to claim 2 , wherein the dye mixing chamber further comprises a filter layer, covering the at least one first through hole.

4 . The dyeing device according to claim 1 , wherein the magnetic dyeing shaft comprises a hollow spool wrapped around a central shaft by the fiber product, a magnetic element located inside the hollow spool, and a connecting surface on a top side of the hollow spool and connecting the hollow spool and the dye mixing chamber, and the connecting surface having the at least one second through hole to allow the fluid to flow therethrough.

5 . The dyeing device according to claim 4 , wherein a flowing compartment is formed between the hollow spool and the magnetic element, and the flowing compartment is wrapped around the central shaft by the hollow spool and connected to the high pressure space through an end of the flowing compartment, which is distal to the connecting surface.

6 . The dyeing device according to claim 5 , wherein the at least one second through hole is connected to the flowing compartment.

7 . The dyeing device according to claim 5 , wherein the hollow spool has a plurality of third through holes on a surface thereof and connecting with the flowing compartment.

8 . The dyeing device according to claim 4 , wherein the magnetic dyeing shaft further comprises at least one one-way valve connected to at least one one-way valve connecting with the at least one second through hole to control a flowing direction of the fluid via the at least one second through hole.

9 . The dyeing device according to claim 1 , further comprising a connecting unit connecting the magnetic dyeing shaft and the dye mixing chamber.

10 . The dyeing device according to claim 9 , wherein the connecting unit comprises a first end and a second end, wherein the first end has a thread to connect with the magnetic dyeing shaft and the second end has a thread to connect with the dye mixing chamber.

11 . The dyeing device according to claim 1 , wherein the fluid is a supercritical fluid.

12 . The dyeing device according to claim 1 , wherein the fiber product is selected from a group consisting of a knitted fabric, a woven fabric, a non-woven fabric or a yarn.

13 . A dyeing apparatus, comprising:
a high pressure steel module, comprising a cover body and a high pressure accommodating chamber to form a high pressure space, which is configured to accommodate a fluid; a dyeing device configured to be accommodated in the high pressure accommodating chamber, and to move inside the high pressure space in a desired direction, the dyeing device comprising:
a magnetic dyeing shaft configured to be wrapped by a fiber product thereon; and
a dye mixing chamber connected to the magnetic dyeing shaft and configured to store a dye, wherein the dye mixing chamber allows the fluid in the high pressure space to flow through the dye mixing chamber; and
a magnetic unit configured to provide a magnetic force to the high pressure space, the magnetic force allowing the magnetic dyeing shaft in the high pressure space to move in the desired direction.

14 . The dyeing apparatus according to claim 13 , wherein the dye mixing chamber comprises:
a chamber configured to store the dye therein; and at least one first through hole which connects the chamber with the high pressure space to allow the fluid to flow in and out of the chamber.

15 . The dyeing apparatus according to claim 14 , wherein the dye mixing chamber further comprises a filter layer, covering the at least one first through hole.

16 . The dyeing apparatus according to claim 13 , wherein the magnetic dyeing shaft comprises a hollow spool wrapped around a central shaft by the fiber product, a magnetic element located inside the hollow spool, and a connecting surface on a top side of the hollow spool and connecting the hollow spool and the dye mixing chamber, and the connecting surface having at least one second through hole to allow the fluid to flow therethrough.

17 . The dyeing apparatus according to claim 16 , wherein a flowing compartment is formed between the hollow spool and the magnetic element, and the flowing compartment is wrapped around the central shaft by the hollow spool and connected to the high pressure space through an end of the flowing compartment, which is distal to the connecting surface.

18 . The dyeing apparatus according to claim 17 , wherein the at least one second through hole is connected to the flowing compartment.

19 . The dyeing apparatus according to claim 17 , wherein the hollow spool has a plurality of third through holes on a surface thereof and connecting with the flowing compartment.

20 . The dyeing apparatus according to claim 16 , wherein the magnetic dyeing shaft further comprises at least one one-way valve connected to at least one one-way valve connecting with the at least one second through hole to control a flowing direction of the fluid via the at least one second through hole.

21 . The dyeing apparatus according to claim 16 , wherein a periphery of the connecting surface and an inner surface of the high pressure accommodating chamber are movably connected with each other.

22 . The dyeing apparatus according to claim 13 , further comprising a connecting unit connecting the magnetic dyeing shaft and the dye mixing chamber.

23 . The dyeing apparatus according to claim 22 , wherein the connecting unit comprises a first end and a second end, the first end has a thread to connect with the magnetic dyeing shaft and the second end has a thread to connect with the dye mixing chamber.

24 . The dyeing apparatus according to claim 13 , wherein the fluid is a supercritical fluid.

25 . The dyeing apparatus according to claim 13 , further comprising a safety valve located at the high pressure accommodating chamber and connected to the high pressure space, the safety valve being configured to be opened when a pressure in the high pressure space reaches a safety threshold.

26 . The dyeing apparatus according to claim 13 , wherein the fiber product is selected from a group consisting of a knitted fabric, a woven fabric, a non-woven fabric or a yarn.
