Precision tests can solve the concerns of these people.

Problem.

Yesterday, the reporter walked into the Shanghai Fiber Inspection Institute and visited "raised in boudoir".

Guard.

As well as all kinds of apparel products, all links in the production industry chain need to be tested, and they all have our potential.

Jin Shuming, chief engineer of Shanghai textile fiber quality supervision and inspection station, said.

Safety testing is an important part in the inspection of textiles and garments.

Whether the formaldehyde content and pH value in clothing are over standard can be determined by a series of chemical tests and scientific tests.

The busiest "baby" needs 4 sets of about 700000 yuan GC-MS to analyze whether azo dyes in clothing meet the standards.

Azo dyes containing carcinogenic aromatic amines can cause harm to the human body. More than 20 aromatic amines have been banned. If one of the samples contains one, the GC-MS can immediately pull it out.

Piercing eye

For example, distinguish wool from cashmere.

"No machine can tell consumers whether this fiber is wool or velvet."

Jin Shuming drew a silk from his sweater, and said that the fiber structure and chemical properties of cashmere and wool were the same. The ordinary combustion method and chemical dissolution method were very difficult to distinguish.

The reporter saw that the fibers under the microscope showed fish scales.

"According to the structure and morphology of scales, the scales are more regular and sparse. They are velvet, with high density and thick scales.

But more often than not, under microscope, the difference between hair and cashmere is very subtle, and we need experience to judge. "

Inspector Xiao Wang, who is more than 30 years old and has made Plush testing for more than 10 years, is the "old wizard" who is worthy of the name.

Each report requires two people to operate independently.

If the error calculated by the two party is within a reasonable scope, a report can be issued.
