Testile Testing Equipment

The principle of the Circular Locus Pilling Test machine . According to the prescribed method and test parameters, use nylon brush and abrasive or single abrasive to make the fabric rub the ball. Then, under the prescribed lighting conditions, the samples were compared with the standard samples to assess the ball grade. Circular Locus Pilling tester test procedure. 1. Preparation before trial. 2. Before the test, the Circular Locus Pilling Test equipment should be kept horizontal and the nylon brush kept clean. If the equipment is used daily, do at least one cleaning work every week. Clean the brush with a suitable solvent (such as acetone) and brush with hand brush to remove short fleece and clip to highlight nylon wire. 3. Put the foam plastic gasket, the sample and the abrasive on the test chuck and the grinding table respectively, and the sample must be facing outwards. 4. According to table 1, adjust the pressure weight and friction rotation number of the sampl

The Hydrostatic head Tester test steps are as follows: 1. Hold the sample in the round table of the test sample. Test points should avoid the edges and folds of the cloth, and use enough tension to make the sample smooth without deformation. Gaskets should be placed on the low pressure side of the specimen (i.e., the side of the sample round table) to prevent air leakage. When there is a difference of air permeability between the two sides of the fabric, it should be recorded in the report. 2. Starting the suction fan is the air passing through the sample, regulating the flow, so that the pressure is gradually approaching the regulation value, and after 1min or when it reaches the stability, the air flow rate is recorded. Using the instrument of differential flowmeter, the appropriate aperture should be selected to record the pressure difference on both sides of the aperture. 3. Repeat at least 10 times in different parts of the same sample under the same conditions. 4. I

Commercial electric automatic clothes washers is to use dry cleaning solvent for washing, solution filtration, dewatering, drying recovery, cleaning solvent, to realize recycling work washing machinery. Dry cleaning machine is the necessary core equipment for the dry cleaning business. Therefore, no matter whether the franchisee chooses to buy the dry cleaning equipment or the equipment recommended by the dry cleaning brand service provider, it is necessary to have an accurate understanding of the dry cleaning machine. The washing system consists of inner cage, main shaft, frequency converter, variable frequency motor, size belt wheel, cover shell and so on. The inverter can change the driving speed of the motor by changing the frequency, so that the rotating speed of the rotating cage can be variable speed, which can meet the various speed requirements of washing, dewatering, drying and deodorization. Through the inverter motor, a pair of belt wheels are driven, so that the rot

Structure of xenon lamp aging tester 1. Test box The test case is made of corrosion-resistant material, and its internal device includes the radiation source and sample frame of the filter system. 2. Radiation source and filtration system. Radiation source is composed of one or more of the xenon lamp, they produce a radiation filter filtered light system, make the irradiance in the sample frame with the relative spectral power distribution of plane of the sun's ultraviolet and visible radiation approximate or with 3 mm glass filtration of solar ultraviolet and visible radiation approximation. 3. Test box body adjustment system. In order to maintain the black mark or blackboard temperature of the test case, the dust air should be circulated in the box, and its temperature and humidity are controlled. The temperature and relative humidity of the air in the test box are controlled by the temperature and humidity sensor, and the sensor is not directly exposed to radiation. The re
