Description

Technical Field

[0001] This utility model relates to a dyeing device, and more particularly to a small sample fabric anti-abrasion dyeing device. Background Technology

[0002] In the dyeing and printing industry, L / D samples are an indispensable and crucial step. These are small-batch dyeing samples prepared in a laboratory environment to test and verify the color, fastness, and other properties of dyes, ensuring they meet customer requirements and standards. L / D samples help manufacturers ensure color accuracy and consistency before mass production, thus avoiding color deviations or other quality problems during production. Furthermore, L / D samples can also be used to test the feasibility and effectiveness of new dyes or dyeing techniques.

[0003] Overflow L / D sample dyeing involves immersing a small sample of fabric and dye solution in a test cup, then attaching the test cup to the dyeing machine. The machine rotates the test cup to maintain the circulation of the dye solution, and infrared heating is used to dye the fabric sample. However, existing test cups lack internal support; the fabric is placed directly inside. During high-speed rotation, the fabric collides and rubs against the inner wall of the cup, causing abrasions. Furthermore, the fabric clumps together, preventing full contact with the dye solution and resulting in uneven dyeing, often leading to fabric creases and streaks. Utility Model Content

[0004] The purpose of this invention is to provide a device for dyeing small-sample fabrics to prevent abrasions. This invention features a simple structure and avoids fabric abrasions, creases, and stripes.

[0005] The technical solution of this utility model: a small sample fabric anti-abrasion dyeing device, including a cup body and a cup lid, the cup body and the cup lid are detachably connected, a spring is detachably connected inside the cup body, the lower end of the spring abuts against the inner bottom of the cup body, the upper end of the spring abuts against the bottom of the cup lid, a small sample fabric is wrapped around the outside of the spring, and the upper part of the spring clamps the upper circumference of the small sample fabric.

[0006] In the aforementioned sample fabric anti-abrasion dyeing device, the lower part of the spring clamps the lower circumference of the sample fabric.

[0007] In the aforementioned sample fabric anti-abrasion dyeing device, the spring is a cylindrical compression spring.

[0008] In the aforementioned sample fabric anti-abrasion dyeing device, the bottom of the cup body is provided with a lower positioning groove corresponding to the lower end of the spring, and the bottom of the cup lid is provided with an upper positioning groove corresponding to the upper end of the spring.

[0009] In the aforementioned sample fabric anti-abrasion dyeing device, the length of the spring is greater than the length of the cup body, the diameter of the spring is smaller than the inner diameter of the cup body, and the spring is compressed inside the cup body by the pressure of the cup lid.

[0010] In the aforementioned sample fabric anti-abrasion dyeing device, the cup body and the cup lid are threadedly connected.

[0011] In the aforementioned sample fabric anti-abrasion dyeing device, the sample fabric is a high-count, high-density chemical fiber fabric.

[0012] In the aforementioned sample fabric anti-abrasion dyeing device, the sample fabric has a yarn count of 40 or higher and more than 200 yarns per square inch.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In use, this invention involves wrapping a small sample of fabric around a spring and clamping the fabric with the upper part of the spring, allowing the fabric to unfold under gravity and stand vertically. The spring is then placed inside the cup, and the lid is placed on top to secure it. This prevents the fabric sample from rolling, tangling, or clumping together during dyeing, thus avoiding fabric abrasions. Without affecting the color, it solves problems such as fabric creases and stripes, resulting in even and beautiful dyeing and improving the dyeing stability and appearance quality of the fabric sample.

[0015] Furthermore, when the cup rotates, because the spring has a hollow structure and there are gaps between the spring coils, it will not affect the flow of the dye liquor, allowing the dye to fully penetrate into the fabric fibers, resulting in good dyeing performance.

[0016] This utility model is convenient to use and simple to operate. It has a simple structure and avoids fabric abrasions, creases, and stripes. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Example:

[0024] like Figures 1-2 As shown, the sample fabric anti-abrasion dyeing device includes a cup body 1 and a cup lid 2, which are detachably connected. A spring 3 is detachably connected inside the cup body 1. The lower end of the spring 3 abuts against the inner bottom of the cup body 1, and the upper end of the spring 3 abuts against the bottom of the cup lid 2. A sample fabric 4 is wrapped around the outside of the spring 3, and the upper part of the spring 3 clamps the upper part of the sample fabric 4 around its circumference.

[0025] In the dyeing process, this invention involves wrapping a small sample fabric 4 around a spring 3 and clamping the upper part of the spring 3 to fix the small sample fabric 4, allowing it to unfold under gravity and become vertical. Then, the spring 3 is placed inside the cup body 1, and the cup lid 2 is placed on top to compress and stabilize the spring 3 and the small sample fabric 4. This prevents the small sample fabric 4 from rolling, tangling, or clumping together when the cup body 1 is rotated and dyed by the dyeing machine, thus avoiding abrasions on the fabric surface. Without affecting the color, this invention solves problems such as fabric creases and stripes, resulting in uniform and beautiful dyeing, and improving the dyeing stability and appearance quality of the small sample fabric 4.

[0026] Furthermore, when the cup 1 is rotated and dyed by the dyeing machine, since the spring 3 has a hollow structure and there are gaps between the coils of the spring 3, it will not affect the flow state of the dye liquor. The dye can fully penetrate into the fabric fibers, and the dye liquor has good fullness and uniformity of coloring.

[0027] The lower coil of the spring 3 clamps the lower circumference of the sample fabric 4, improving the stability of the sample fabric 4 within the cup body 1.

[0028] The spring 3 is a cylindrical compression spring.

[0029] The bottom of the cup body 1 is provided with a lower positioning groove 11 corresponding to the lower end of the spring 3, and the bottom of the cup lid 2 is provided with an upper positioning groove 21 corresponding to the upper end of the spring 3. The lower positioning groove 11 and the upper positioning groove 21 limit and fix the spring 3, improve the dyeing stability, and prevent the spring 3 from shifting or shaking when the cup body 1 rotates for dyeing.

[0030] The length of the spring 3 is greater than the length of the cup body 1, and the diameter of the spring 3 is smaller than the inner diameter of the cup body 1. The spring 3 is compressed inside the cup body 1 by the pressure of the cup lid 2. The compressed state of the spring 3 inside the cup body 1 can compress the fabric and ensure the dyeing stability of the fabric.

[0031] The cup body 1 and the cup lid 2 are threaded together.

[0032] The sample fabric 4 is a high-count, high-density synthetic fiber fabric.

[0033] The sample fabric 4 has a yarn count of 40 or higher, and more than 200 yarns per square inch.

[0034] The same small sample fabrics were dyed using both conventional color testing cups and this device under the same dyeing conditions, resulting in fabric A (conventional color testing cup) and fabric B (dyeing device of this invention). Figure 3 As shown. From Figure 3 It can be seen that the small sample fabric dyed using this device has more uniform coloring and no problems such as creases or streaks.

[0035] The parts of this utility model not described in detail are existing technologies and therefore will not be specifically described here.
