Example Embodiment

[0037] Example 1 Device for testing dynamic moisture absorption data of fabrics

[0038] A device for testing dynamic moisture absorption data of fabrics. The device includes a constant temperature and humidity box 1, model: SDH0501, and manufacturer: Chongqing Yinhe Testing Instrument Co., Ltd.

[0039] Main Specifications:

[0040] Temperature measurement accuracy: ±0.3%F.S±1.0

[0041] Temperature measurement accuracy: ±0.5% F.S ±1.0 (when the humidity temperature is between 20~90℃)

[0042] ±1%F.S±1.0 (when humidity is between 15~100℃)

[0043] Equipped with sensor: use two paired Pt100 platinum resistors for dry and wet temperature measurement.

[0044] The diameter of the test plug is the same as the aperture of the operation hole, and the length of the test plug is 50-60 mm, preferably 50 mm. The test plug is made of foam (polystyrene foam). The aperture of the operation hole is 50-90 mm, preferably 60 mm.

Example Embodiment

[0050] Example 2 Method for testing dynamic moisture absorption data of fabric

[0051] (1) Prepare the fabric to be tested, and bake the fabric to be tested in an oven at 105°C for 2.5 hours. After drying, the fabric should be placed in a dryer immediately after being taken out, and weighed after cooling. 0 ;

[0052] (2) Device debugging: turn on the power, check the water level of the constant temperature and humidity tank, the water level should be above the outlet valve, the electronic balance adjusts the level; the electronic balance is set to zero, the left door of the balance cover of the electronic balance is opened, and the thermostat is closed door;

[0053] (3) After setting the temperature and humidity of the thermostat according to the experimental plan, put the ventilation, heating and humidification buttons in the on position (refrigeration needs to be turned on when the humidity is less than 95%), press the switch button, and the thermostat starts to work;

Example Embodiment

[0061] Example 3 According to the method of Example 2, dynamic data measurement experiment under different humidity at 20°C

[0062] Experimental materials:

[0063] Ordinary polyester fabric provided by Beijing Tongniu Group has a plain weave. The fabric is used ethyl acetate solution to remove impurities such as oil and wax, washed with soap, rinsed with warm water, dried and shaped. The main parameters of the fabric are listed in Table 1.

[0064] Table 1 Main parameters of fabric

[0065]

[0066] Experimental determination:

[0067] Using the method of the present invention, the moisture absorption dynamic data of ordinary polyester at a temperature of 20°C and different humidity (humidity 20%, 40%, 60%, 80%, and 98%) were measured, and the results are listed in figure 1 .

Description

technical field [0001] The invention relates to a method for testing the moisture absorption data of fabrics, in particular to a device and a testing method for testing the dynamic moisture absorption data of fabrics. Background technique [0002] Simply put, clothing comfort is the characteristic that the human body feels comfortable when wearing clothing, but it involves many fields, such as psychology, physiology, physics, materials science and human sociology. Among them, heat and humidity comfort is an important aspect of research on clothing comfort. The research on heat and humidity comfort of clothing has a history of more than 40 years abroad. The focus of development and research includes physiology and psychology, fabric structure, fiber Raw materials and finishing. In terms of heat and humidity comfort testing instruments, the United States and Western Europe focus on thermal mannequins that can simulate the functions of various parts of the human body and prost...
