ACID DYES IN PRINTING PROCESS
Nylon is the most easily dyeable fiber among synthetic fibers for its high swelling and absorbing properties. Our acid and metal complex dyes are most suitable for the printing of polyamide 6 or 6.6 among those, ACID dyes are considered to be essential for nylon printing because of their brilliancy in shade, fastness properties and excellent affinity to the fibers, the METAL COMPLEX DYES which is suitable for printing process is recommended in this shade card

ACID & METAL-COMPLEX DYESTUFFS
Ariacid dyes are used for dyeing wool and they have been specially developed for dyeing and printing polyamide fibers. That Acid dyes can be appliced on both polyamide 6 and 6.6 fibers with an appropriate selection of products for all application sectors and processing stages. These dyes are classified based on group “A”, “B”, “C” which are recommended to the dyes by functional information Our metal-complex dyes are disulphonated 1:2 metal complex dyes used for dyeing wool and polyamide fibers and giving high level of light and wet fastness. They are also suitable for resist and displacement printing of carpets
ACID & METAL-COMPLEX DYELING PROCESS
The shade card contains extensive information based on our present knowledge on the dyeing of wool and polyamide, it contains specific data on the application possibilities of our dyes and chemical on wool and polyamide fibres, both alone and in blend with other fibers. In addition to data on pretreatment selection of dyes and dyeing chemicals and dyeing processes
