Dye cellulose fiber dyeing, dye devoured the gender is good, in the 100 ℃ temperature when the biggest affinity. Discharge the gender is good. Hard to sensitive. Dyeing copper and iron ions in a slight discoloration. Mainly used in viscose and their blended fabric dyeing and printing, and can also be used to knit fabric, blankets and silk, polyamide fiber fabric dyeing and printing, and can also be used in leather, paper and plastic color.
1. It has been used for dyeing cotton or viscose fiber to get reddish brown. Poor transferability, sensitive to salt, slow temperature rise during dyeing and salt addition to control dyeing, can obtain uniform color. The rate is good. The highest dyeing temperature is 100 °C.
2. It has been used for dyeing rich fiber, good dyeing rate, similar color and cotton. It has also been used for dyeing or printing silk and its fabrics, adding Yuanming powder and acetic acid during dyeing, printing method with cotton And viscose fabric. When dyeing vinyl fabric, the dyeing rate is general, the color light is lighter than cotton. When cotton, viscose fiber and other fibers are dyed in the same bath, the silk color is darker than yellow and the wool is darker than yellow. , nylon and cotton are similar, acrylic, diacetate, polyester have a very slight stain, three vinegar fiber does not stain.
3. It has been dyed with high-temperature dyeing and blending fabrics with disperse dyes, and the color shade is basically unchanged. The dye bath is adjusted with ammonium sulfate to adjust the pH value, and it is heated to 120 ° C under neutral or slightly alkaline conditions, or loaded. Body boiling dyeing, after the dye is dyed with polyester, the dyeing is continued for half an hour, so that the cellulose fibers are fully colored to promote the dye exhaustion.
4. It has also been used for direct printing of cotton or viscose fabrics. It is printed with deep-dense pattern, plus urea and disodium hydrogen phosphate to prepare color paste. It is also an important dye for ground color discharge.
5. It has been used mainly for the dyeing and printing of viscose fiber and its fabrics. It is one of the main brown direct dyes. It has also been used for dyeing or printing cotton knits, carpets and silk fabrics. In addition to being used alone, it is often used in combination with yellow, red, gray and other brown dyes. It is very fast when dyeing light colors, and gradually dyed at high temperatures when dyeing dark colors.
Direct Brown 95 contains carcinogenic aromatic amine benzidine, which is a banned dye. The substitute dye is direct dark brown N-M,direct blended brown D-RS.
Direct Brown 95 is formulated primarily for cellulosic fibres — cotton, rayon (viscose) and linen — and performs best on 100% cellulosic or high-cellulose blends. It is not recommended for polyester without special carriers or high-temperature processes.
A common starting point: liquor ratio 1:20, 40–60°C initial fill, add dye at room temperature dispersed in water, then raise to 60–70°C and hold 30–60 minutes. Typical salt addition is used to promote exhaustion — start with a moderate salt level and optimize for your mill. Always run small lab trials and adjust for shade and fabric type.
After-treatments help: thorough soaping (mild nonionic detergent at elevated temperature), followed by oxidizing or reducing cleaners when suitable. Optical brighteners and commercial wash-fastness improvers (fixing pads or cationic after-baths) can significantly raise wet fastness. Trial different soaping temperatures and times to balance hand and fastness.
Yes — it is compatible with many textile printing binders and auxiliaries. For printing, disperse the dye finely and test binder interaction. Post-fixation (steam or cold pad-fix) and an appropriate wash-off are recommended to remove unfixed dye and prevent crocking.
It can be used in blends with other substantive dyes (other direct or vat dyes) for shade adjustments, but compatibility tests are essential. When mixing with reactive dyes, consider sequencing and pH differences; reactive dyes may require different fixation steps.
Run a shade reproducibility test, wash and crock fastness tests (ISO or AATCC equivalents), and levelness checks on both small swatches and pilot runs. Measure exhaustion and bath coloration to tune salt and temperature. Document recipes and offsets for consistent scale-up.
