Flammability Tester

Textiles are usually exposed to light during use, which can destroy dyes and cause "fading", discoloring colored textiles, generally lighter and darker. Is there any way to simulate sun exposure? The answer is yes, that is to use a xenon lamp aging test chamber. The lightfastness of dyes used in the textile industry varies widely, and some method of determining their colorfastness is necessary. In addition, the dyed material will also affect the light fastness of the dye. The test method of the xenon lamp aging test chamber for textiles is: Expose the test cloth samples and a group of lightfast blue wool standard samples dyed with blue dyes of different color fastness grades at the same time and under the same conditions. When the cloth sample has faded sufficiently, compare the cloth sample with the blue wool standard sample. If the fading degree of the cloth sample is similar to that of the blue wool standard sample 4, then its light fastness is rated as 4. The Q-sun Xenon ...

How can I accurately test the shrinkage of textile fabrics? Weaving yarns are unisex materials, warp and weft yarns are not interwoven into the fabric before, can be under a certain tension in a straight state, but when weaving, warp and weft yarns interlocked floating, the yarn is changed from the original straight state into a waveform flexure state, the length is shortened, thus forming a different structure of the fabric, so that the length of the woven fabric is shorter than the original length of the yarn and the formation of weaving shrinkage. Weaving shrinkage has an impact on the strength, thickness, density, weight, appearance and shrinkage of the finished product. As the warp and weft yarns of raw material thickness, density and fabric organization and on the machine process parameters, etc. different, warp and weft yarns can have a variety of cooperation between the relationship, therefore, the weaving shrinkage rate is also different.   Fabric weaving shrinkage rate is...

Horizontal Vertical Flame Tester for Textiles Roles The burning of textiles may produce smoke and toxic gases that affect the health of the operator, and the tester should wear a gas mask. The tester can be installed in a fume hood and the smoke and soot should be removed after each test, but the ventilation system should be turned off during the burning of the specimen to avoid affecting the test results. KS-5455D Textile Horizontal Vertical Flame Tester adopts the one-piece structure and the principle of large box over small box, the combustion box is placed in the fume hood made of baked cold plate, the left panel of the cold plate fume hood has instrument timer, ignition button, lighting, exhaust and other functional buttons. The upper part of the fume hood is installed with the exhaust air and smoke vent connected with the interior of the combustion chamber, and the interior is installed with a soot cleaning device, and the soot handling device is composed of dust removal plate an...

The Textile UL94 Horizontal Vertical Flame TesterTechnical Parameters UL94 Horizontal Vertical Flame Tester technical parameters： 1. Sample frame: It consists of a rectangular metal frame. 12 sample fixing pins are installed along the long side of the rectangular frame with a length of 560mm and a width of 150mm. The distances between the sample fixing pins and the bottom edge are 5mm, 10mm and 190mm respectively. , 370mm, 550mm and 555mm, the length of the fixed pin is 30mm. 2. Template: used for sampling for sample drilling. 3. Timing device: time the three marking lines respectively, and the timing stops automatically when each marking line is burnt. 4. Combustion gas source: industrial propane or butane or propane/butane mixed gas (provided by the user) 5. Sample: L560mm*W170mm, 3 pieces each in the warp and weft direction

Never forget the concentration test method of ozone aging test chamber 3 methods of concentration test in  Ozone aging test chamber ： 1, electrochemical method: the use of ozone in water in the electro-activated surface of the point of chemical reduction, point of change in the current curve in the circuit is proportional to the concentration of ozone in solution, this instrument has a data output function, can be measured online and can achieve closed-loop feedback control of the ozone generator, currently used in large water treatment projects. 2, iodine measurement method: the classic measurement method in the past, the ozone concentration is calculated by the number of sodium thiosulfate consumed by using the ozonation gas to make the iodine oil in the potassium iodide solution out of the color, and then titrating the reduction to colorless with sodium thiosulfate. This method of color development intuitive, inexpensive equipment, but to use a variety of drugs, wash bottles, me...

3 Quick Notice Operation Tips For Horizontal Vertical Flame Chamber Horizontal Vertical Flame Chamber must learn 4 operating precautions: Precautions. 1、 Check whether the liquid in the U-tube meets the requirements before opening the gas (the liquid level should be at 0 level), if the bottom is at 0 level, please replenish the liquid, otherwise the gas will leak outward from the U-tube. When using different gases, the pressure size of the gas is different, thus affecting the ignition effect. At this time, the control amount of the air pressure adjustment valve under the combustion seat must be adjusted, and at the same time, it should be adjusted with the gas flow adjustment switch and air adjustment device to get the standard flame. 2, the equipment must have a reliable electrical grounding circuit protection. 3、The moving part of the Bunsen burner is carried by bearings, therefore, the bearing rod should be kept clean and wiped with a wipe cloth with oil regularly to make the bearin...

10 Common Myths About Vertical Flammability Test Chamber 10 Common Myths About  Vertical Flammability Test Chamber : 1、Check whether the power supply voltage meets the equipment requirements before use.   2、Check carefully whether there is gas leakage from the gas pipe and joints before starting the machine, and confirm that it is normal before conducting the test operation.   3, Vertical Flammability Test Chamber test samples, some materials will release toxic and harmful gases, it is recommended that the test should be carried out in the fume hood, and good human protection. 4, the test in the fume hood, after each test to discharge the gas generated by the test process and other combustible gases, replace the fresh air. 5, the test process to take precautions to reduce the fume hood ventilation during the test, you can check the ventilation through the flue ventilation equipment.   6, at the end of the test, first close the gas main valve, burning despite the comb...
