Abrasive sandblasting is not toxic to the wearer
Take a pair of Chinese lacquer production to the Textile Institute, KS PhiNam Zhang, Head of Research, has pointed out to us the characteristics of this type pants grinding technology. Accordingly, jeans have been grinding out 2-3 times. A first white lacquer with sandblasted in pants pocket. Then once again wear pants for the whole body with micro abrasive pumice community. Particularly bears are sharpening stone to tear cracks.
According to KS Truong Phi Nam, jeans are usually dyed with indigo drugs, as dyes poor color fastness, just sticking rings pants outside surface, not deep into the fibers. After dyeing, to make it beautiful to wear more details.
Blasting grinding technology using spray sand (sand-sized gold particles normally appropriate) to create pressure. At this time, the friction of sand and unstable dye will fade color pants. However, in this technology toxic to people dressed as inaccurate.
"To sandblasted needed equipment such as high pressure sandblasting gun, spray chamber and withdraw handle sand ... That when you need to populations in a closed chamber, head shot gun from outside to inside, then have the technology to clean out sand washing clothes and recovered sand it again. so there can be no more talk of sand sticking out of jeans when sold for export to affect the wearer pneumoconiosis. there Maybe this is a misinterpretation of the information received, "stressed KS Truong Phi Nam.
Also, can the process of sandblasting abrasive affect the health of workers by machines is not guaranteed to work or do not properly process manually ... no isolation chamber thereby allowing the dust flying out. There has not been announced yet banned the use of technology in abrasive sandblasting clothing in the world or in Vietnam.
How to Tell wear pants chemicals
KS Truong Phi Nam said that besides grinding sand blasting technology is also the other way as pumice stone grinding, grinding with chemicals or microorganisms combined pumice stone, abrasive chemical ... Mai by micro, ie to microbial discoloration, wear and tear where necessary. This does not affect the health of users. In the abrasive grinding on the chemical at high risk for the user. Because there are many types of chemicals like javen, potassium ... and all those toxic chemicals.
"Chemicals are characterized by discoloration more abrasive so fast. But to residual chemicals in fabric, hardly lost after only one wash. Potassium is considered non-toxic, but javen (chlorine ) have the ability to influence, though not as dangerous as the carcinogens in or dye fabric is original formandehyd Izo. the greatest danger is that people use drugs or banned unpublished, may cause harmful incalculable . However, no study, published about the risk of foreign substances, "the South African KS Zhang stressed.
How to detect wear jeans sandblasting or grinding stone grinding in the direction of jeans is local, ie, only wear a few places. For instance, the bear population usually stone grinding, sandblasting or often in the pocket, the pants ... Private grinding chemical characteristics are grinding, grinding wide as both populations have the same color. To ensure the safest, after buying clothes cleaned up, dried and then wear.
Currently the textile factories in the industry of Vietnam mainly grinding jeans probiotics combined with pumice, sand blasting machine is not used. Not so toxic that sand blasting machine by many factors such as clothing Vietnam cows do not compete with other countries, especially China.
