Description

A clothing windproof performance testing tool and testing method Technical Field

[0001] The present invention relates to a clothing testing tool and a testing method, in particular to a clothing windproof performance testing tool and a testing method. Background Art

[0002] Existing garment windproofing tests primarily focus on fabrics, which are typically determined by measuring their breathability. This method is not intuitive. If garments are tested using fabric windproofing methods, the front and back panels create two barriers, failing to accurately reflect the garment's actual single-layer windproofness. Furthermore, the garment's shape can affect airflow, distorting test results.

[0003] Currently, there is no tool or method that can intuitively and accurately test the windproof performance of clothing after wearing.

[0004] Summary of the Invention

[0005] In response to the above-mentioned shortcomings of the prior art, the present invention provides a clothing windproof performance testing tool to intuitively and accurately test the windproofness of clothing when worn, avoiding the influence of clothing appearance factors. The present invention also provides a clothing windproof performance testing method.

[0006] The technical solution of the present invention is as follows: A clothing windproof performance testing tool includes a prosthesis, which includes a transparent back panel, a longitudinal partition and a transverse partition. The transparent back panel has a projected contour of a human body trunk. The longitudinal partition is fixed to the transparent back panel at a certain interval in the transverse direction. The front side of the longitudinal partition has a concave-convex structure, and a three-dimensional contour of the human body trunk is formed around the front side of the longitudinal partition. The transverse partition is fixed to the transparent back panel at a certain interval and is fixedly connected to the longitudinal partition. The longitudinal partition and the transverse partition enclose a plurality of test compartments. A test cloth belt is provided in the test compartment. The upper end of the test cloth belt is connected to the top surface of the test compartment, and the lower end of the test cloth belt naturally droops.

[0007] During the test of the present invention, half of the clothing is worn on the prosthesis, and the movement state of the test cloth belt is observed through the transparent back plate to perform the test.

[0008] Furthermore, in order to make it easier to continuously observe the test tape and facilitate the test operation, another technical solution is: a clothing windproof performance testing tool, including a prosthesis, the prosthesis including a backboard, a longitudinal partition and a transverse partition, the backboard has a projection contour of a human torso, the longitudinal partition is fixed to the backboard at a certain interval in the transverse direction, the front side of the longitudinal partition has a concave and convex structure, and a three-dimensional contour of the human torso is formed around the front side of the longitudinal partition, the transverse partition is fixed to the backboard at a certain interval and fixedly connected to the longitudinal partition, the longitudinal partition and the transverse partition are combined to form a plurality of test compartments, a test tape and an image sensor are provided in the test compartment, the upper end of the test tape is connected to the top surface of the test compartment, the lower end of the test tape naturally droops, and the image sensor is used to capture the status image of the test tape.

[0009] The solution of the present invention can use an ordinary back plate to make a prosthesis by setting an image sensor, and the prosthesis can be fully worn during testing without special treatment. Therefore, the operation is more convenient, and the operator can observe outside the test environment, making the test more convenient and safer.

[0010] Furthermore, the upper end of the test tape is connected to the front edge of the transverse partition.

[0011] Furthermore, the length of the test tape is 10 to 15 cm.

[0012] Furthermore, the transverse partitions are arranged at the chest line, waist line and hip line of the prosthesis.

[0013] Furthermore, the interval between the longitudinal partitions is 8 to 10 cm.

[0014] Another technical solution of the present invention is: a method for testing the windproof performance of clothing, which is based on the aforementioned clothing windproof performance testing tool, wherein the clothing to be tested is worn on the prosthesis, a fan is set in front of the prosthesis to blow towards the prosthesis at a fixed wind speed, the fluttering state of the test cloth belt on the prosthesis is observed, and the windproof level of the clothing to be tested is determined according to the fluttering state of the test cloth belt. If the test cloth belt continuously remains parallel to the transverse partition, it is windproof level 0; if the test cloth belt flutters in an inclined manner and the lower end of the cloth belt is less than 1 cm away from the transverse partition connected to the test cloth belt, it is windproof level 1; if the test cloth belt continuously flutters in a flapping manner, it is windproof level 2; if the test cloth belt flutters at intervals, it is windproof level 3; if the test cloth belt is stationary, it is windproof level 4.

[0015] The technical solution provided by this patent has the following advantages: it is applicable to testing the windproof performance of all outerwear garments, allowing for intuitive observation of windproofness without requiring fabric air permeability testing to determine windproofness. The windproof performance testing tool provided by this patent is simple to manufacture and operate, and the corresponding windproofness rating of the garment can be easily determined by measuring the fluttering state of the cloth tape. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] FIG1 is a schematic structural diagram of a clothing windproof performance test tool. DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the following examples. It should be understood that these examples are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading this description, various equivalent modifications to this description by those skilled in the art fall within the scope defined by the claims appended to this application.

[0018] Please refer to Figure 1. The clothing windproof performance testing tool involved in this embodiment includes a prosthesis, which is mainly composed of a backboard 1, a longitudinal partition 2 and a transverse partition 3. The backboard 1, the longitudinal partition 2 and the transverse partition 3 can be made of solid wood multi-layer boards, specifically, they are made of more than three layers of one-millimeter solid wood thin boards through gluing and hot pressing, and have high strength and good stability.

[0019] The shape of the prosthesis is made based on the human torso. In this embodiment, the prosthesis forms the front half of the human torso and responds to the frontal windproof test. The backboard 1 is formed according to the positive projection contour of the human torso, and the longitudinal partitions 2 and the transverse partitions 3 are fixed on the front side of the backboard 1. The transverse partitions 3 are arranged perpendicular to the backboard 1 and are respectively arranged at the hip line, waist line and chest line of the prosthesis. According to the standard female body shape, the hip line is 12 cm away from the lower end of the prosthesis, the waist line is 28 cm away from the hip line, and the chest line is 24 cm away from the waist line. A transverse partition 3 at the neck line can also be set at the top. The outer circumference of each transverse partition 3 is set according to the standard female body shape, with the chest circumference set to 84 cm, the waist circumference set to 66 cm, and the hip circumference set to 92 cm.

[0020] The longitudinal partitions 2 are also vertically arranged on the surface of the back plate 1, spaced 8 to 10 cm apart from the central axis of symmetry. In this embodiment, five longitudinal partitions 2 are arranged at 8 cm intervals. (It should be noted that longitudinal partitions 2 in the same longitudinal direction are considered a single piece, but can be installed in sections during actual production.) The longitudinal partitions 2 are also fixedly connected to the transverse partitions 3. In this way, the longitudinal partitions 2 and transverse partitions 3 are fixed to each other in the vertical and horizontal directions and connected to the surface of the back plate 1, and the longitudinal partitions 2 and transverse partitions 3 enclose a plurality of test chambers 4.

[0021] Some test compartments 4 are fitted with test tapes 5. The upper ends of these tapes are attached to the outer edges of the transverse partitions 3 with adhesive tape, while the lower ends are left hanging naturally. Typically, the tapes are 10 to 15 cm long, though this can be adjusted slightly depending on the specific placement. For typical testing, at least two test compartments 4 below the transverse partitions 3, located at the hip, waist, and chest lines, are fitted with test tapes 5 to achieve more accurate test results.

[0022] Because the clothing obscures the test compartment 4 when the prosthesis is dressed, an image sensor 6 is also provided within the test compartment 4 where the test tape 5 is located to capture images of the test tape 5 during the test. The image sensor 6 can be connected to a monitoring device via a cable, allowing the tester to observe the test tape 5 outside the test environment.

[0023] During the test, after the garment was placed on the prosthesis, a large-diameter fan was positioned 2.5 meters in front of the prosthesis, blowing air perpendicularly to the backboard 1 at a set wind speed of level 8 (17.2-20.7 m / s). Because the fan is a larger wind source relative to the prosthesis, the wind field surrounding the prosthesis can be considered relatively stable. Although the test compartments 4 formed on the prosthesis are not coplanar and have different angles relative to the wind source, the deviations are negligible compared to a relatively stable wind field.

[0024] Observe the fluttering state of the test tape 5 on the prosthesis, and determine the windproof level of the tested clothing based on the fluttering state of the test tape 5. According to the test statistics of 50 pieces of clothing, the states of the test tape 5 and the windproof levels are as follows: if the test tape 5 is continuously kept parallel to the horizontal partition 3, it is windproof level 0, and the clothing is suitable for indoor wear or in an environment with weak wind; if the test tape 5 flutters in an inclined manner and the lower end of the tape 5 is less than 1 cm away from the horizontal partition 3 connected to the test tape 5, it is windproof level 1, and the clothing can withstand slight wind; if the test tape 5 continues to flutter in a flapping form, it is windproof level 2, and the clothing is suitable for daily wear in normal weather; if the test tape 5 flutters at intervals, it is windproof level 3, and the clothing is suitable for outdoor activities with strong wind; if the test tape 5 is stationary, it is windproof level 4, and the clothing is suitable for outdoor activities in bad weather or extreme environments. Because the structure of a garment may vary from place to place, the test tape 5 within each test compartment 4 may have various fluttering states. Based on the aforementioned evaluation criteria, the windproof strength of the garment structure at each location can be clearly determined. This can then guide garment designers to adjust the garment structure based on the windproof level determined by the fluttering state of the test tape 5. For example, the test tape 5 can be kept horizontally and an additional layer of windproof fabric can be added. This testing method can therefore help technicians enhance the windproof performance of the garment structure.

[0025] The aforementioned embodiment uses the prosthesis as the front half of a human torso. It should be noted that the prosthesis can also be configured as a complete human torso, as needed. Specifically, longitudinal and transverse partitions 2 and 3 are similarly provided on the back side of the back panel 1 to form a test chamber 4, thereby facilitating windproof testing of the garment from both the front and rear directions.

[0026] In another embodiment, the prosthesis is configured as the left or right half of a human torso. In this embodiment, a transparent back panel is selected for manufacturing, and the transparent back panel is parallel to the front-to-back direction of the human torso. The transverse partitions are also arranged at the hip, waist, and chest lines of the prosthesis, while the longitudinal partitions are arranged perpendicular to the transparent back panel and are parallel to the left-right direction of the human torso. The setting of the test tape is the same as in the aforementioned embodiment and will not be repeated here. In addition, since a transparent back panel is selected, the condition of the test tape in the test compartment can be directly observed through the transparent back panel, and therefore, an image sensor may not be provided in the test compartment. During testing, this embodiment is mainly used to test the lateral windproof performance of the garment. When the garment is worn on the prosthesis, only the left or right half of the garment needs to be worn. In this way, the transparent back panel will not be blocked, and the windproof level can be judged by directly observing the condition of the test tape in the test compartment.
