Fiber Textile Testing Laboratory Open

The laboratory of Shenzhen textile and textile supervision and Inspection Institute located in Qingdao road was first opened for free for the first time. Under the leadership of vice president Li Zhaoyong, the reporter entered the fiber textile testing laboratory. At the first glance, he saw the treasure of "town house" imported from the United States - A liquid phase tandem mass spectrometer with a value of 1 million 930 thousand yuan.

"If we wear newly bought clothes or use newly bought textiles, we can use this instrument to detect whether the clothes are carcinogenic sensitizing dyes." Laboratory testing personnel. The detection process is to extract the dyestuffs from the samples by chemical reagents, put them into a small transparent glass bottle, and put them into the instrument. The instrument can be judged through a series of automatic analysis, and it can be judged whether the dye contains carcinogenic sensitizing substances within 40 minutes.

Li Zhaoyong said that the detection of carcinogenic sensitizing dyes was not previously available. "After having this instrument, it can undergo the examination of the project in April and May about the relevant approval procedures." However, testing is not free, and the specific charges are not yet fixed.

Some of the anti radiation maternity clothes sold on the market are even called "blocking 99.99% of radiation", and the function testing for radiation protection clothing has always been blank. On the 13 day, the reporter saw from the laboratory that the testing equipment of radiation protection clothing had been launched, and it was about to receive test items in April and May. The full name of the testing equipment is called the fabric electromagnetic radiation resistance tester. The tester has a sample placing port. The fabric is placed on the port, compacted, and the electromagnetic radiation is released through the computer operating instrument. The electromagnetic radiation transmittance of the sample within a certain area is the electromagnetic shielding property of the sample. The whole process takes only 1 minutes. In addition, UV blocking rate can also be detected. It takes about 2 minutes.

The fiber textile laboratory has also increased the detection of volatile gases in textile products. The name of the detection equipment is GC / MS, which is worth 750 thousand yuan. "Some clothes smell bad when they wear them for the first time. They smell pungent, headache and discomfort." Inspectors said that these volatile substances, formaldehyde, benzene and other carcinogens, through clothing and human body direct contact, the harm is very large.

In addition, laboratory pairs Infant clothing 5 kinds of copper, lead, chromium, arsenic and mercury are mainly detected. heavy metal The equipment used is a power coupled plasma mass spectrometer imported from the United States worth 1 million 500 thousand yuan. It can measure more than 10 kinds of heavy metals. It is the most advanced detection equipment in the province.

How many real clothes do you wear in down coats? Down "How much is broken chicken feather?" "feather down content" is an important indicator of the quality inspection of feather and down products. 13, reporters in Qingdao fiber textile testing laboratory learned that the original detection of down content is entirely a detection point by the naked eye.

"This is eiderdown, a little one, very soft, and every corduroy is covered with smaller fuzz, which is a high quality waterfowl feather." The inspector used a tweezers to pick up a feather to show the reporter. According to the quality, the best is the down feather, then the silk, feather, feather and feather. The worst is the broken chicken feather. "Feathers have the highest thermal performance, and the broken chicken feathers are the worst." The inspector said.

In the hands of the inspectors, there is a mysterious "photo album", which contains all kinds of high-definition pictures of feather and feather. The inspectors in the 4 grams of samples, with the naked eye a little bit to distinguish feather, velvet, feather, duck feather, chicken feather and other categories, and then compared with the "photo album" visual contrast, identified ingredients, weighing, calculated feather content, feather content, feather content, chicken feather content.
