Overview

Direct dyes are anionic dyes substantive to cellulosic fibers when applied from an aqueous bath containing electrolyte. Many of them also dye protein fibers. Direct Dye is a class of dyestuffs that are applied directly to the substrate in a neutral or alkaline bath. They produce full shades on cotton and linen without mordanting and can also be applied to rayon, silk, and wool. Direct dyes give bright shades but exhibit poor wash fastness. Various after treatments are used to improve the wash fastness of direct dyes, and such dyes are referred to as “after treated direct colors.”Direct Dyes are molecules that adhere to the fabric molecules without help from other chemicals. Direct dyes are defined as anionic dyes with substantivity for cellulosic fibers, normally applied from an aqueous dyebath containing an electrolyte, either sodium chloride (NaCl) or sodium sulfate (Na2SO4).

Product Description

APPLICATION:

Direct dyes are usually applied with the addition of electrolyte at or near the boil in the machines capable of running at atmospheric pressure. But in HTHP dyeing machines it is carried out at temperatures above the boil in case of pure as well as blended yarns.

An addition of alkali, usually sodium carbonate, may be made with acid-sensitive direct dyes and with hard water as well as to enhance the dye solubilisation. When cellulose is immersed in a solution of a direct dye it absorbs dye from the solution until equilibrium is attained, and at this stage most of the dye is taken up by the fibre. The rates of absorption and equilibrium exhaustion vary from dye to dye. The substantivity of the dye for cellulose is the proportion of the dye absorbed by the fiber compared with that remaining in the dyebath.

*Please refer to our technical for further information.

Properties:-

1. Water soluble dyes

Buyer questions

Frequently asked by buyers

Common questions B2B buyers ask before sourcing DIRECT DYES. Answers compiled from verified sellers' commercial terms and platform data.

Q: Can direct dyes be used for dyeing blended yarns with cellulosic and protein fibers?

A: Yes, direct dyes can be applied to blended yarns containing cellulosic fibers and protein fibers such as silk and wool, typically using high-temperature high-pressure (HTHP) dyeing machines to achieve better uptake.

Q: How is the wash fastness of direct dyes improved?

A: Wash fastness can be enhanced by subjecting dyed fabric to after-treatment processes, leading to 'after treated direct colors' which exhibit improved color durability.

Q: Is mordanting necessary when using direct dyes on cotton fabrics?

A: No mordanting is required for direct dyes when applied on cotton or other cellulosic fibers as these dyes substantively adhere to fibers in an electrolyte containing alkaline dyebath.

Q: What electrolytes are commonly used in the direct dyeing process?

A: Sodium chloride (NaCl) and sodium sulfate (Na2SO4) are the commonly used electrolytes to promote exhaustion of direct dyes on fabric.

Q: Are direct dyes suitable for acid-sensitive dyeing applications?

A: Direct dyes that are acid sensitive may require the addition of alkali such as sodium carbonate in the dye bath to ensure proper solubilisation and uptake by fibers.
