Opening of the hottest fiber textile testing labor

2022-08-05
  • Detail

In 2014, the fiber textile testing laboratory of Qingdao Municipal Bureau of quality supervision received a total of 26000 batches of fiber textiles, involving more than 30 categories such as children's clothing, bedding, suits and so on. On the 13th, the laboratory was opened free of charge for the first time, and witnessed in advance the "artifact" of three new testing items, namely, the radiation protection performance of fabrics, carcinogenic and sensitizing dyes, and volatile gases

The carcinogenic dye was detected in 40 minutes at 9:30 a.m. on the 13th, the laboratory of Qingdao Institute of fiber textile supervision and inspection, located in Shenzhen road, was opened free of charge for the first time. Under the leadership of vice president Li Zhaoyong, he entered the fiber textile testing laboratory and saw at a glance the "treasure of the town", a liquid phase tandem mass spectrometry (LC-MS) worth 1.93 million yuan, which had just been imported from the United States

"if we wear new clothes or use new textiles and have red itching and other allergies after contact with the body, we can use this instrument to check whether the clothes are used with carcinogenic and sensitizing dyes." Introduction to laboratory testing personnel. The test process is to use chemical reagents to extract the dye components from the test samples, put them into a small transparent glass bottle, and then put them into the instrument. The instrument can automatically analyze them through a series of automatic analysis, and can judge whether the dye contains carcinogenic and sensitizing substances within 40 minutes

lizhaoyong said that the detection of carcinogenic sensitizing dyes had not been available before. "With this instrument, after relevant approval procedures, the project can be tested in April and may.". However, the test is not free, and the specific charging standard has not been determined

1 minute detection of anti radiation clothing

some of the anti radiation maternity clothing sold on the market even said that it can block 99.99% of the radiation, and the function detection of anti radiation clothing has always been blank. On the 13th, it was seen from the laboratory that the testing equipment for radiation protection clothing had been launched, and the testing items would be received in April and may, and the testing was also charged. The full name of the testing equipment is called the fabric anti electromagnetic radiation performance tester. The tester has a sample placement port. The tested fabric is placed at the port, compacted, and the electromagnetic radiation is released through the computer-operated instrument. The actual anti electromagnetic performance of the sample is to see the electromagnetic radiation transmittance within a certain area of the sample. The whole process only takes 1 minute. In addition, the UV barrier rate can also be detected, which takes about 2 minutes

heavy metals can be found in infant clothing

the fiber textile laboratory has also newly added the detection of volatile gases in textile articles. The name of the testing equipment is gas chromatography mass spectrometer, with a value of 750000 yuan. "Some clothes will have a peculiar smell when they are worn for the first time. They smell pungent, headache and discomfort are obvious." According to the inspectors, among these volatile substances, formaldehyde and benzene are carcinogens, which are in direct contact with the human body through clothes, causing great harm

in addition, the laboratory focuses on the detection of five kinds of heavy metals such as copper, lead, chromium, arsenic and mercury in infant clothing. The equipment used is an electric coupling plasma mass spectrometer imported from the United States with a value of 1.5 million yuan. With the increasingly mature research and development technology of C919, Yun 20, J 20 and other domestic aircraft, it can detect more than 10 kinds of heavy metals. It is the most advanced detection equipment in the province at present

- discover the quality of down. It depends on the naked eye to identify how much real down there is in your down jacket? How many are broken chicken feathers? "Down content" is an important indicator for the quality inspection of down products. On the 13th, it was learned in Qingdao fiber and textile testing laboratory that the original detection of down content was completely identified by the inspectors with their naked eyes

"this is the down, a small one, very soft. Each down silk is covered with finer down. This is high-quality waterfowl down." The inspector picked up a feather with tweezers and showed it to him. According to the quality, the best is complete down, then down silk, feather pieces, feather silk and feathers, and the worst is broken chicken feather with stalk. "Down has the highest heat preservation performance, and broken chicken feathers have the worst heat preservation performance." The inspector said

the inspectors have a mysterious "photo album" in their hands, which contains high-definition pictures of various down and feathers. In the 4G sample of raw materials upstream of the layout of longmang Baili for titanium dioxide price increase, the inspectors use the naked eye to distinguish various categories such as down, down silk, feather, duck feather, chicken feather, etc., and then visually compare them with the "photo album". After identifying the components, they weigh them to calculate the content of down, feather, feather, chicken feather, etc
