CRABYON is totally new fiber
based on the technology of making Chitin/Chitosan
The idea behind the
development of CRABYON is the fact that chemical
structure of Chitin/Chitosan is quite similar
to that of cellulose.
The idea led to development of technology
to make Chitin/Chitosan viscose. CRABYON,
composite fiber of Chitin/Chitosan and cellulose,
is manufactured by uniformly blending Chitin/Chitosan
and cellulose viscose and extruding the blended
viscose into spin-bath.
We have got a patent for this technology in
Japan and U.S.A under the title Process for
producing articles of regenerated Chitin/Chitosan
containing material and the resulting articles'.
The same patent is pending in U.K., Germany,
France, Italy, and Austria.
There are two other types of fibers containing
After treatment type
Chitin/Chitosan is fixed on the fabric with
binder. Jt is apparent that Chitin/Chitosan
decrease as fabric is washed, leading to lesser
function. Jt is afraid that the binder might
damage the skin.
Chitin Chitosan powder is simply mixed with
cellulose viscose. So long as physical properties
of fiber weakens as percentage of powder increases,
there is a limit of quantities of powder to
be mixed. (Fig. 2)
As you can see, CRABYON is completely different
from the above two types fiber.
