Polyvinyl Alcohol Fiber Development Overview
ANHUI LIWEI CHEMICAL CO.,LIMITED
Polyvinyl Alcohol Fiber use Polyvinyl
Alcohol
as the raw material of
textile fibers.
Polyvinyl Alcohol ( Polyvinyl Alcohol
abbreviation: PVA) was
synthesized and spun into fibers by German
chemist Herrmann and
Haehee in 1924.
Because of its water solubility, Polyvinyl
Alcohol fiber can not be
used for clothing.
Japanese chemist Ichiro Sakurada and Korea
chemist Lee Seung Gi do a
heat treatment and reduction of formaldehyde
on Polyvinyl Alcohol
fibers, and get the good heat water property
Polyvinyl Formal Fiber
in 1939.
1950 in Japan, Polyvinyl Formal Fiber achieved
industrial
production, the tradename of Polyvinyl
Alcohol is Vinylon. In
Chinese it is also called Vinylon or Polyvinyl
Alcohol.
In August 1963, China introduced from Japan
Kuraray PVC sets of
annual output of 10000 tons of productsion
equipment and
construction in Beijing Shunyi. And in 1965,
it has been put into
production.
Between 1963 and 1983, China has builty 14
Vinylon factory, the
annual production capacity of
Polyvinyl
Alcohol
is of 165000 tons. But because of Vinyl taking
poor yields had
dropped after 1981.
And the production of Polyvinyl Alcohol has
been gradually
stabilizing after 2000.
In 2003, the totol production of Vinylon was
32600. And until today,
there is still a great demand for Polyvinyl
Alcohol Fiber.
