Abstract
Description
Technical Field
[0001] The invention relates to the technical field of thermal insulation testing devices, in particular to a thermal insulation testing device for fabrics. Background Art
[0002] Fabric is the material used to make clothing. As one of the three elements of clothing, fabric can not only interpret the style and characteristics of clothing, but also directly affect the color and shape of clothing. Different fabrics have different air permeability, moisture absorption, warmth retention and other properties. For example, cotton fabric has good air permeability and moisture absorption, is comfortable to wear, and has good warmth retention. It is the most ideal fabric for children's clothing. When choosing fabric, you must confirm the fabric's air permeability, warmth retention, moisture absorption, static electricity and other performance characteristics, and then consider the fabric's stiffness, weight, softness, hardness and drape to consider what kind of shape and style it is suitable for.
[0003] Thermal insulation refers to the thermal conductivity of an object. Thermal insulation is also called thermal insulation. It is the property of a material that blocks heat transfer to varying degrees. It is generally the ability to reduce the impact of the outdoor comprehensive temperature on the indoor surface temperature by resisting the entry of outdoor heat through the building's external envelope structure. Generally, the unit volume thermal conductivity of the medium is used as a simple and comprehensive measure. The three basic modes of heat conduction must also be considered: radiation, convection, and transfer.
[0004] As global temperatures rise, especially in high-temperature working environments (especially outdoor work in hot summer and high-temperature workplaces such as steel and oil), continuous high temperatures can cause workers to feel a lot of physical discomfort and are very likely to cause a series of changes in physiological functions, which are very harmful to the human body. Therefore, the thermal insulation performance of fabrics is particularly important. Testing the thermal insulation performance of fabrics can guide people to develop fabrics with better thermal insulation. At present, workers are usually required to manually test the thermal insulation performance of fabrics. Workers need to observe the fabrics in real time and record temperature changes, which wastes manpower, and the measurement results are prone to errors and cannot be accurately measured. Therefore, it is necessary to design a fabric thermal insulation test device. Summary of the invention

[0050] In this embodiment, a method for using a fabric thermal insulation testing device is as follows:
[0051] S1, the operator places the fabric inside the clamping area of the first clamping block 9 and the second clamping block 15, rotates the first fixing bolt 11 and the second fixing bolt 17 to fix the fabric, and preheats the fabric to improve the accuracy and stability of the fabric thermal insulation test;
[0052] The power control shaft 1 701 and the rotating shaft 1301 are started at the same time to drive the first clamping block 9 and the second clamping block 15 to rotate slowly and uniformly, and the solar simulator 23 is started to preheat the fabric to simulate the temperature of the actual environment, and the preheating temperature threshold range is set to b. When the temperature of the front and back sides of the fabric reaches the preheating temperature threshold range, the preheating process ends;
[0053] Specifically, the first clamping block 9 and the second clamping block 15 rotate to the top of the temperature sensor 29 every 30 seconds through the rotating shaft 1 701 and the rotating shaft 2 1301, the moving unit controls the cylinder 25 to move from left to right on the top of the detection chamber 2, starts the driving unit, controls the temperature sensor 29 to move downward to detect whether the preheating of one side of the fabric is within the preheating temperature threshold range b, the power starts to control the rotating shaft 1 701 and the rotating shaft 2 1301 to start at the same time to drive the first clamping block 9 and the second clamping block 15 to rotate 180 degrees, and the temperature sensor 29 detects whether the preheating of the other side of the fabric is within the preheating temperature threshold range b, and the above steps are one cycle;
[0054] When the temperature sensor 29 detects that both sides have not reached the preheating temperature threshold range b, another cycle of rotation is performed until the temperature detected by the temperature sensor 29 reaches the preheating temperature threshold range b;
[0055] When the temperature sensor 29 detects that one side reaches the temperature threshold range b, the power supply starts to control the rotating shaft 1 701 and the rotating shaft 2 1301 to start simultaneously to drive the first clamping block 9 and the second clamping block 15 to rotate 180 degrees, and the other side of the fabric is preheated by the solar simulator 23 until the temperature reaches the temperature threshold range b;
[0056] When the temperature sensor 29 detects that both sides have reached the temperature threshold range b, the preheating process is ended and the temperature sensor 29 returns to the initial position to perform a thermal insulation test on the fabric.
[0057] S2, detect the current fabric thickness and use different heating methods for fabrics of different thicknesses;
[0058] Specifically, taking pure cotton fabric as an example, after the fabric is fixed in the clamping area of the first clamping block 9 and the second clamping block 15, since the fabric is used not only in indoor environments but also in outdoor environments, it is necessary to perform a heating test or a simulated sunlight irradiation test on the surface of the fabric, start the thickness measuring unit, and detect the thickness of the fabric;
[0059] When the detected fabric thickness is below 0.1mm, it is set as H1 (light and thin fabric). Because the fabric with the current detected thickness is light and thin, its thermal insulation is also low, so it is not suitable to use the electric heater 5 to heat the current fabric. By starting the simulated irradiation unit to simulate sunlight irradiation on the fabric surface, the fabric surface is heated. The fabric surface is irradiated by the solar simulator 23, which will not cause damage to the fabric.
[0060] When the thickness of the fabric to be tested is set to H2 (medium-thick fabric) between 0.1-0.3mm, because the fabric to be tested is medium-thick fabric, its thermal insulation is also low and it is not suitable to use a higher temperature to test the current fabric. The electric heating unit controls the electric heater 5 to start, adjusts the temperature of the electric heater 5 to a low level, and electrically heats the fabric of this thickness.
[0061] When the thickness of the fabric to be tested is set to H3 (thick fabric) when the thickness is above 0.3mm, because the fabric of the current thickness to be tested is thick fabric, its thermal insulation will be higher. A higher temperature is used to test the current fabric. The electric heating unit controls the electric heater 5 to start, and adjusts the temperature of the electric heater 5 to a high level to electrically heat the fabric of this thickness.
[0062] S3, start the timing module to measure the time required for the temperature change on the surface of the fabric to detect the thermal insulation of the surface of the fabric;
[0063] Specifically, when detecting light and thin fabrics, the fabric is fixed by the first fixing bolt 11 and the second fixing bolt 17, the first linear motor 6 and the second linear motor 12 are started, and the first clamping block 9 and the second clamping block 15 are controlled until the fixed fabric is located above the solar simulator 23, the power is turned on to start the solar simulator 23, and the surface of the fabric is heated. The solar simulator 23 is driven by the rotating frame 22 to rotate at a uniform speed to provide uniform heat for the fabric. When the surface of the fabric is heated, the timing module and the detection module are started at the same time. The detection module detects the temperature of the fabric surface after being heated for a period of time. The surface of the fabric with a thickness of H1 is set to be irradiated by the solar simulator 23, and the surface of the fabric is heated and irradiated for T 光 After time (T 光 is artificially set), irradiation T 光After a certain time, when the solar simulator 23 heats the lower surface of the fabric with a thickness of H1, the operator starts the moving unit to control the cylinder 25 to move from left to right on the top of the detection chamber 2, starts the driving unit, controls the temperature sensor 29 to move downward until the infrared rays of the infrared sensor 1 are blocked, and the first moving block 901 and the second moving block 1501 move toward the middle to clamp the temperature sensor 29, so that the temperature sensor 29 can detect the real-time temperature more stably, and detect the temperature of the upper surface of the fabric in real time. At the same time, the timing module measures the heating exposure time of the fabric, and the temperature sensor 29 is The sensor 29 detects the temperature indicated on the fabric and records it. When the temperature sensor detects that the temperature of the fabric changes, the irradiation time of the solar simulator 23 is recorded as t1 and the solar simulator 23 is turned off. The first moving block 901 and the second moving block 1501 are restored to the initial position, and the temperature sensor 29 is controlled to retract upward.
