Description

Technical Field

[0001] This utility model relates to the technical field of immersion test equipment for testing the water retention performance of hydrophobic fabrics. Background Technology

[0002] In recent years, with the continuous development of science and technology, textile finishing techniques have become increasingly diversified. By appropriately combining different hydrophilic and hydrophobic yarns and auxiliaries, fibers can be endowed with different hydrophilic and hydrophobic properties. For example, single-layer unidirectional moisture-wicking fabrics can be prepared, or single-sided hydrophobic finishing, single-sided hydrophilic finishing, or hydrophilic-hydrophobic double-sided finishing can be used to create differences in moisture absorption on both sides of the fabric.

[0003] Water absorption refers to the ability of textiles to absorb water under certain conditions, and it is one of the important indicators of the wetting performance of textiles. Fabrics made of natural plant and animal fibers (such as cotton and linen) have excellent hydrophilic properties and sink relatively quickly after being soaked in water. Fabrics made of chemical fibers (such as polyester and polypropylene nonwoven fabrics) do not easily absorb water and float on the surface after being soaked in water. Synthetic fiber blends have different fiber structures and chemical compositions, resulting in different forces between them and water molecules during soaking, and thus different water absorption capacities. When testing some water absorption items, because fabrics made of different types of fibers have different affinity for water, some fabrics are not completely submerged in water during soaking, and part of them float on the surface. Even with the help of external force (such as using a weight to force the fabric into the water), some parts of the surface will be blocked from contact with water due to the external force, resulting in certain differences in the degree of penetration and wetting. When measuring the water retention properties of fabrics, this will have a significant impact on the data results, and it is difficult to simulate the actual state of human-worn fabrics when soaked in water.

[0004] In view of the above, it is necessary to develop an auxiliary device for fabric immersion testing that can conveniently control the floating state of hydrophobic fabrics when immersed in water, achieve uniform water coverage, and avoid uneven data results due to different immersion degrees, which would affect the test results of the fabric. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned problems in the prior art and provide an auxiliary device for measuring the water retention performance of fabrics, so as to achieve uniform coverage of the immersion water of the fabric in water and improve the accuracy of the test results.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An auxiliary device for measuring the water retention performance of fabrics includes an open-ended transparent container, a support plate, a positioning rod, and a positioning frame. The side wall of the transparent container is vertically equipped with a scale. The upper end of the positioning rod is vertically connected to the support plate, and the lower end of the positioning rod is vertically connected to the positioning frame. The positioning frame is a square or circular frame with a centrally intersecting line. In application, the support plate is placed on the rim of the transparent container, and the height of the positioning frame is within the range of the scale.

[0008] Furthermore, the transparent container can be a 500-1000mL beaker. The scale is preferably a 10-15cm millimeter-scale ruler.

[0009] The diameter of the support plate is larger than the opening of the transparent container. In use, the support plate is simply placed on the rim of the transparent container. The support plate is preferably made of metal sheet.

[0010] Furthermore, the upper end of the positioning rod is movably connected to the support plate via nuts or other means, allowing the depth of the positioning frame within the viewing container to be adjusted as needed.

[0011] Furthermore, the positioning frame is a square frame with a centrally located intersecting line; even further, the square frame has dimensions of 70×70mm. Furthermore, the intersecting line and frame line of the positioning frame are both waterproof metal round lines with a diameter of 0.5-1mm. Even further, the lower edge of the positioning frame has equally spaced 1-5mm deep retaining strips, which are also waterproof metal round lines with a diameter of 0.5-1mm.

[0012] Furthermore, there are four positioning rods, the lower ends of which are perpendicularly connected to the four corners of the positioning frame, and the upper ends of which are perpendicularly connected to the support plate; the support plate is also provided with a positioning hole, the center point of which is on the same vertical line as the center point of the positioning frame.

[0013] The beneficial effects of this utility model are:

[0014] The auxiliary device provided by this utility model for determining the water retention performance of fabrics effectively controls the suspension state of the fabric in water, allowing water molecules to evenly cover the sample surface, and enabling the fabric to be immersed according to the set depth, pressure and time, which greatly improves the accuracy of the water retention performance test results of hydrophobic fabrics.

[0023] The specific embodiments described herein are merely illustrative of the technical solutions of this patent and are not intended to limit the disclosed technical solutions. It should also be noted that, for ease of description, the accompanying drawings show only the parts relevant to the technical solutions of this application, and not the entire structure.

[0024] Before discussing the exemplary embodiments in more detail, it should be mentioned that the structure of the device components and / or modules mentioned in the embodiments, unless otherwise described in detail, is something that can be understood by those skilled in the art based on existing public technologies or is a commercially available product.

[0025] refer to Figure 1 This embodiment provides an auxiliary device for measuring the water retention performance of fabrics, including an open-ended transparent container 1, a support plate 2, a positioning rod 3, and a positioning frame 4. The side wall of the transparent container 1 is vertically provided with a scale 101. The upper end of the positioning rod 3 is vertically connected to the support plate 2, and the lower end of the positioning rod 3 is vertically connected to the positioning frame 4. The positioning frame 4 is a square or circular frame with a centrally intersecting line. In application, the support plate 2 is placed on the rim of the transparent container 1, and the height of the positioning frame 4 is within the range of the scale 101.

[0026] The transparent container 1 can be a 500-1000mL glass beaker, and the scale 101 is preferably a 10-15cm scale in the millimeter range.

[0027] The diameter of the support plate 2 should be larger than the opening of the transparent container 1. In use, the support plate 2 can be placed directly on the rim of the transparent container 1. The support plate 2 is preferably made of metal sheet, which has a certain weight and can press down the fabric suspended in the water below the positioning frame.

[0028] A further preferred embodiment is that the upper end of the positioning rod 3 is movably connected to the support plate 2 via nuts or the like, allowing the positioning frame 4 to be adjusted to the accurate depth within the transparent container 1 by referring to a ruler as needed, and then fixed.

[0029] The positioning frame 4 preferably has a square frame with intersecting lines at its center, and the size of the square frame should be appropriate for the size of the test sample. A square frame with a size of 70×70mm can meet most test requirements. Furthermore, the diameter of the intersecting lines and frame lines of the positioning frame 4 is fixed at 0.5-1mm, which is a waterproof metal circle, so that the non-water contact surface on the upper surface of the sample is as small and standardized as possible.

[0030] To prevent the hydrophobic fabric sample from floating and moving in water, a further preferred solution is to install 1-5mm deep baffles at equal intervals along the lower edge of the positioning frame 4. These baffles are made of waterproof metal round wire with a diameter of 0.5-1mm. If it is a square frame positioning frame, four baffles can extend from the four bottom corners.

[0031] Another option is to install four positioning rods 3, with the lower end of each positioning rod 3 perpendicularly connected to the four corners of the positioning frame 4, and the upper end of each rod perpendicularly connected to the support plate 2, providing a more stable downward pressing structure. Additionally, a positioning hole 201 is provided on the support plate 2, with the center point of the positioning hole 201 aligned vertically with the center point of the positioning frame 4.

[0032] Using the auxiliary device for testing the water retention performance of fabrics provided in the above embodiments, after the hydrophobic fabric sample floats in the water of the container, the positioning frame is pressed down to the set position and then covers the support plate to the container opening. The sample is in a fixed suspended state, which uniformly determines the immersion depth (water pressure) and the almost unobstructed immersion area, ensuring that water molecules uniformly and comprehensively cover the surface of the fabric sample. After setting the measurement time, the immersion data of each test sample has high reproducibility, improving the accuracy of the water retention test results of hydrophobic fabrics.
