Some dyes function in liquid form\u2014such as soluble dyes\u2014yet are chemically synthesized.
\nProcesses involving dispersion and enhanced solubility within the system influence the dye’s molecular structure, resulting in specific performance characteristics.
\nThese dyes offer high wash fastness and good light fastness\u2014factors considered to be of significant importance.<\/p>\n
Certain formulations involve both non-ionic and ionic dyes, which must be properly applied to ensure the desired outcome and durability. Non-ionic dye series are suitable for various types of fibers, such as nylon, acrylic, and cotton.<\/p>\n
In some instances, these materials serve as yellow dyes and provide stable performance.<\/p>\n
These substances belong to the category of reactive salts or amino-compounds. In some instances, electrodes and orbital energy are utilized, while in others, low energy consumption is involved.
\nThe effects of this group on dye solutions are rapid and consistent.<\/p>\n
Classification of some Polynor resins based on the type of active group:<\/p>\n
Nitrate-ester molecules exhibit high chemical reactivity; therefore, the dyeing process for polyester fibers is carried out at temperatures of 85\u201390\u00b0C.<\/p>\n
Polyester molecules possess high chemical reactivity; consequently, high temperatures cause the dye to degrade. These dyes exhibit good transparency. Dyeing temperatures for this class typically range from 85\u00b0C to 90\u00b0C. These dyes are utilized in new color applications. Regarding the alkali levels used for this class…
\n(pH = 10,10)<\/p>\n
Direct dyes constitute the counterpart to this category of dyes.<\/p>\n
Direct dyes: These are generally dyes that exhibit sensitivity to light intensity.
\nDue to low molecular activity, this category shows poorer fastness to washing and light.<\/p>\n
Physical properties:
\nSome direct dyes penetrate fibers and become fixed within them through the action of dispersing agents.
\n2. They are typically applied at high temperatures.
\n3. These dyes are suitable for cotton, viscose, and cellulosic fibers.
\n4. This category is not suitable for nylon.<\/p>\n
