Problems solved by technology

However, olfactometry largely relies on human subjectivity, lacks objectivity, and can only make a comprehensive evaluation of odorous gases, and cannot accurately determine the composition of odorous gases, so as to find out the source of the odor

Embodiment 1

[0038] Put 2.0±0.2g of the prepared textile 1 cotton lining into the emptied air bag 3, seal the air bag 3 with the sealing strip 2, open the air bag valve 9, and fill in 3L of the test product with a concentration of 100ppm Gas ammonia, close the air bag valve 9. After waiting for the test textile 1 cotton lining to absorb the ammonia gas to be tested for 1 hour, open the gas valve 9, use the gas controller 8 to extract a certain amount of odorous substances from the air bag 1, detect the residual concentration of the ammonia gas to be tested, and observe The reading of the concentration scale 7 on the glass tube 4. Once again, wait for the test textile 1 cotton lining to absorb the test gas ammonia for 1 hour, and then use the same method to detect the residual concentration of the test gas ammonia. When the cotton lining of the textile to be tested adsorbs the ammonia gas to be tested for 2 hours, the adsorption reaches equilibrium, and the residual concentration of the am...

Embodiment 2

[0041]Put the prepared 2.0±0.2g bamboo charcoal fabric containing silver ions in the textile to be tested 1 into the emptied air bag 3, seal the air bag 3 with the sealing strip 2, open the air bag valve 9, and fill 3L with a concentration of 100ppm The gas to be measured ammonia, close the air bag valve 9. After the bamboo charcoal fabric containing silver ions in the textile to be tested absorbs the ammonia gas to be tested for 1 hour, open the gas valve 9, extract a certain amount of odorous substances from the air bag 1 with the gas controller 8, and detect the residual ammonia gas of the gas to be tested Concentration, observe the reading of the concentration scale 7 on the glass tube 4. Once again, wait for the bamboo charcoal fabric containing silver ions in the textile 1 to be tested to absorb the gas to be tested, ammonia, for 1 hour, and then use the same method to detect the residual concentration of the gas to be tested, ammonia. When the bamboo charcoal fabric co...

Embodiment 3

[0044] Put the prepared 2.0±0.2g hemp socks of the textile to be tested 1 into the emptied air bag 3, seal the air bag 3 with the sealing strip 2, open the air bag valve 9, and fill in 3L of the gas to be tested with a concentration of 100ppm Ammonia, close the air bag valve 9. After the hemp socks to be tested absorb the ammonia gas to be tested for 1 hour, open the gas valve 9, extract a certain amount of odorous substances from the air bag 1 with the gas controller 8, detect the residual concentration of ammonia gas to be tested, and observe the glass Reading of concentration scale 7 on tube 4. After waiting for the test textile 1 hemp socks to absorb the test gas ammonia for 1 hour, use the same method to detect the residual concentration of the test gas ammonia. When the textile to be tested 1 hemp socks adsorbed the gas to be tested, ammonia, for 2 hours, the adsorption reached equilibrium, and the residual concentration of the gas to be tested, ammonia, was measured. ...

Abstract

The invention relates to a detecting device and a detecting method for the deodorizing performance of textiles. The detecting device comprises an air bag, an air bag valve, connecting tubes, a glass tube and a gas controller, the air bag is a rectangular outer frame, three sides of the rectangular outer frame are sealed, the other side of the rectangular outer frame is sealed by a sealing strip, the textiles to be detected are placed in the air bag, the air bag is provided with the air bag valve which is connected with the front end of the glass tube through one connecting tube, and the rear end of the glass tube is connected with the gas controller through the other connecting tube. By the aid of the detecting device, gas to be detected can be rapidly detected, the concentration of the gas to be detected is detected accurately and efficiently, the deodorizing performance of the textiles can be reliably detected, and timely and accurate site detection data are provided.

Description

technical field [0001] The invention belongs to the technical field of detection, and in particular relates to a detection device and a detection method for the deodorization performance of textiles. Background technique [0002] At present, more and more deodorizing textile products have entered the market, and people's demand for such textiles is also increasing, but it is difficult for ordinary consumers to distinguish the authenticity of the products. Starting from the protection of consumer rights and environmental coordination factors, the research and formulation of test methods for textile deodorization ability and related standards should be implemented as soon as possible, so as to standardize the market transactions of deodorant products, so as to protect the legitimate rights and interests of consumers. [0003] The 6-level odor intensity display method widely used in Japan is one of the detection methods for textile deodorization, that is, to judge the deodoriza...
