Enquiries and orders for Danfix increase in overseas markets
In recent years, the number of enquiries and orders coming from overseas is
increasing for "Danfix," fixing agents of Nitto Boseki Co., Ltd., for
use in reactive and direct dyeing. Its sales territory has been expanding to
include India and Pakistan which have seen an upturn in sales. Customers needs
have begun to shift away from low quality and low priced products, as had previously
been feared, to high quality and low priced products, and "Danfix SC-8" has
been chosen and used for regular recipes in dyeing firms in various countries.
Meanwhile, the textile industry in Asia still shows no sign of slowing down,
and the processing which had once been seen as high-value-added processing in
Japan, including especially water-absorbent and quick-dry finishes, has become
common. It is considered that demand for water-absorbent and quick-dry finishes
will further rapidly increase abroad, and that for "Danfix SC-8" can
be expected to increase more as well.
In these circumstances, it is expected that demand for "Danfix SC-8," a
fixing agent of Nitto Boseki Co., Ltd., will further increase both domestically
and internationally, with its special feature of not causing any hindrance to
water absorbency at post treatment, its fastness and its excellent hand.

Moreover, orders for Danfix 202 capable of producing water-absorbent effects are coming from every corner of the world.’
‘In China, there is a growing trend favoring water-absorbent/quick-dry treatment as a kind of high value-added finishing. Fixing agents used for this need to be of a type that does not cause hindrance to water absorbency.’
