Description

Technical Field

[0001] This utility model belongs to the field of yarn cages, specifically relating to an anhydrous dyeing and sampling yarn cage. Background Technology

[0002] Traditional textile dyeing and printing processes are inefficient, energy-intensive, and highly polluting, posing risks to the environment and human health. They also generate large amounts of dye wastewater. New sustainable waterless dyeing methods have emerged as a viable solution to this problem. Supercritical CO2 dyeing uses carbon dioxide instead of water as the dye solvent. Utilizing the unique solubility and diffusion properties of supercritical CO2, it dissolves dyes and penetrates fibers, achieving not only highly efficient dyeing but also allowing for the recycling and reuse of CO2 after dyeing.

[0003] Before mass dyeing production, small-scale dyeing samples need to be produced to determine the dyeing process and effect. Currently, dye cups are used for small-scale dyeing tests. However, there are currently no special sample yarn cages for waterless dyeing. Moreover, when using existing yarn cages, the yarn cages collide with the dye cups, causing scratches on the smooth inner wall of the dye cups, which makes it easy for dye to remain on the inner wall of the dye cups, which has an adverse effect on cleaning and subsequent dyeing. Utility Model Content

[0004] To address the problem that existing yarn cages cause scratches on the smooth inner wall of the dye cup when they collide with it, leading to insufficient dye dissolution, this application designs an anhydrous dyeing sample yarn cage. This design aims to provide a certain impact buffer when the yarn cage collides with the inner wall of the dye cup during supercritical CO2 dyeing sample testing.

[0008] The outer cylinder is provided with collars at both ends, and the outer cylinder is fitted onto the outer step of the collar; the end cap is pressed onto the inner step of the collar.

[0030] Example 1

[0031] Please refer to Figure 1 and Figure 2 This embodiment mainly introduces the basic design of an anhydrous dyeing sample yarn cage, including an inner cylinder 1 and an outer cylinder 2;

[0032] The inner cylinder 1 is disposed in the middle of the outer cylinder 2;

[0033] The inner cylinder 1 is connected to end caps 3 at both ends;

[0034] The outer cylinder 2 is provided with collars 4 at both ends, and the outer cylinder 2 is fitted onto the outer step of the collar 4; the end cap 3 is pressed onto the inner step of the collar 4.

[0035] Furthermore, both the inner cylinder 1 and the outer cylinder 2 are porous tubes or sintered metals with breathable structures (to facilitate dye penetration).

[0036] Furthermore, the collar 4 is made of a non-metallic material, and the hardness of the collar must be lower than that of the dye cup. Non-metallic materials such as PTFE, PEEK, or PI are recommended.

[0037] Furthermore, the outer diameter of the collar 4 is slightly larger than the outer diameter of the outer cylinder 2, so that only the collar contacts the dye cup when the yarn cage moves. This avoids scratching the inner wall of the dye cup and provides a certain impact buffer.

[0038] Furthermore, the inner cylinder 1 and the outer cylinder 2 are fixedly connected by bolts.

[0039] Furthermore, the end cap 3 is provided with first bolt holes evenly distributed on it;

[0040] The collar 4 is provided with a second bolt hole, and bolts are inserted into the first bolt hole and the second bolt hole to achieve a fixed connection between the outer cylinder 2 and the inner cylinder 1.

[0041] Furthermore, the inner cylinder 1 can also be replaced by a smooth rod.

[0042] Furthermore, the outer diameter of the yarn cage is smaller than the inner diameter of the dye cup, leaving a gap, and the length of the yarn cage is smaller than the inner length of the dye cup. During dyeing, the dye cup is placed radially and rotated on the vertical turntable of the heating unit, allowing the yarn cage to move axially within the dye cup under the action of gravity, which is beneficial for the dissolution of dye and uniform dyeing.

[0043] This application designs a waterless dyeing sample yarn cage, comprising an inner cylinder and an outer cylinder; the inner cylinder is positioned in the middle of the outer cylinder; end caps are connected to both ends of the inner cylinder; collars are provided at both ends of the outer cylinder, and the outer cylinder is fitted onto the outer steps of the collars; the end caps press against the inner steps of the collars; both the inner and outer cylinders are porous tubes; the collars are made of non-metallic material; the outer diameter of the collars is slightly larger than the outer diameter of the outer cylinder. The novel yarn cage designed and prepared in this application ensures that only the collars contact the dye cup during yarn cage movement, thus avoiding scratching the inner wall of the dye cup and providing a certain impact cushioning effect.

[0044] The above description is merely a preferred embodiment of this utility model and does not limit the scope of protection of this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any changes, modifications, substitutions, integrations, and parameter alterations made to these embodiments within the spirit and principles of this utility model, through conventional substitutions or methods that achieve the same function without departing from the principles and spirit of this utility model, fall within the scope of protection of this utility model.
