Clothes "Fingerprints" Reveal The True Colors Of Clothes.

< p > close a target= "_blank" href= "//www.sjfzxm.com/" > dress < /a > is it 100% pure cotton? Under the microscope of the laboratory, all secrets will be "real truth". If the colourful fabrics are not aware of danger? Azo test can tell you the answer!

< p > here, a piece of clothing can not be casually worn on the body. Instead, it must be tested through fiber composition, color fastness, formaldehyde content pH value, azo and even odor, and so on.

< /p >

< p > no matter it is a very ordinary shirt or a luxury a href= "//www.sjfzxm.com" > high-end fashion < /a >, in the Panyu quarantine inspection bureau's eco a target= "_blank" href= "//www.sjfzxm.com/" > textile "/a" product testing laboratory engineer, all the clothes are made up of a small fiber.

< /p >

< p > < strong > fiber "fingerprint": < /strong > < /p >

< p > < strong > let "fish in troubled waters" nowhere to hide "/strong > /p".

< p > is this garment 100% pure cotton? Is this really a silk quilt? "Only by hand can you roughly determine the composition of the clothes, and many of the complaints from customers involve such problems."

Laboratory staff briefed reporters.

"But under the microscope, all kinds of < a href=" //www.sjfzxm.com/news/ > fiber > /a > will be "exposed."

< /p >

< p > the staff demonstrated to reporters the shape of ordinary fibers under microscope.

"You see, there is a natural twist in the longitudinal appearance, irregular twist along the length of the fiber, and the natural twist is a peculiar feature of natural cotton fibers, and the size of each fiber is also inconsistent.

The synthetic fiber is smooth and the size is almost the same. It is easy to distinguish! "< /p >

< p > in the laboratory computer, at least store thousands of different kinds of fiber's original "archives map", such as human fingerprints, each fiber has a unique atlas character, the detected fiber and the "map" are compared, it is possible to determine the true face of the fabric! < /p >

< p > < strong > resistance to wear. < /strong > < /p >

< p > < strong > after "suffering" is qualified. < /strong > /p >

< p > in the laboratory, a machine that keeps on rocking has attracted the attention of journalists. The 6 metal heads are constantly rubbing friction on the fabric, which is a special instrument for testing the wearability and pilling of clothing.

"Any clothing must be accepted here for tens of thousands of tests."

According to regulations, the textile is checked every 5000 or 10000 times to see if the fiber is broken or worn. If it passes the 20000 pass, it will be qualified.

< p > on the side of the laboratory, the workers are cutting the palm size sample into the < a href= "//www.sjfzxm.com/news/index_c.asp" > fabric < /a >.

"This is mainly used for burning!" the staff said, "flame retardancy is also an indicator of < a target=" _blank "href=" //www.sjfzxm.com/ > > clothing > /a > especially for export garments. "

< /p >

< p > according to introduction, there are different standards for flame retardancy of fabrics. In a specific combustion chamber, if a specific source of fire is used, if it is a smooth fabric, it can persist to 3.5 seconds even if it is qualified.

< /p >

< p > < strong > clothes poisonous? < /strong > < /p >

< p > strong > formaldehyde and azo are invisible killers < /strong > < /p >.

< p > perhaps we often hear that a batch of clothes is not qualified because the formaldehyde content exceeds the standard.

In fact, the detection of formaldehyde content is only one of dozens of chemical tests to be carried out. < a href= "//www.sjfzxm.com" > ecological detection < /a > important also includes heavy metal, antimony, arsenic, lead, cadmium, chromium, feather down microbes, textile antibacterial properties testing.

< /p >

< p > azo detection is a very important test we are not familiar with.

The staff told reporters that clothes are basically dyed. In order to make the colors more colorful and not easy to fade, some undesirable manufacturers often add azo to dye. Azo is a strong carcinogenic chemical.

< /p >

Detection of azo is a dangerous journey. < p >

"We generally say that the extraction is to cut the sample according to certain specifications, then extract it in a specific solution, then restore it, then the upper column (including purification, separation, concentration), and then dissolve and machine. The whole process will take about a day."

The staff told reporters, "azo is carcinogenic substances, if the check" a href= "//www.sjfzxm.com" > fabric < /a > contains relatively high volume, and long-term contact, has an impact on the body. "
