Direct Dyes
Direct Dyes are another class of dyes that are part of mixing components in 'all purpose' dyes and do not require any type of fixing with other dyes. These dyes are eligible for lightfast dyeing and are also resistant to fading in light. These comprise conjugated molecular structures also containing one/more anionic sulfonate group which also makes these soluble in water. We can offer these in both powder as well as in liquid concentrate form.
Features :
- Some shades of these dyes are more lightfast in comparison to similar shades of fiber reactive dyes.
- Have sulphonate that improves solubility
- Their flat shape & length allows them to lie along-side cellulose fibers as well as maximize Van-der-Waals, dipole and hydrogen bonding
Applications :
- Direct dyes are used on cellulose fibers like :
- Cotton
- Rayon
- Linen
