Direct Yellow RL

Product Application

Direct yellow RL is most suitable for dyeing of viscose like cotton,flax, viscose rayon, acetate and jute, also for ink, leather and paper coloration.

Product Property

1.Direct yellow RL is soluble in water.

2.Direct yellow RL is for the dyeing of cotton and viscose fibers in a one-bath one step dyeing process for polyester-cotton, polyester bonded or cotton-nitrile blended fabrics. It can be dyed in the same bath as the disperse dyes or as a direct dye.

3.Direct yellow RL can be used as a substitute dye for Direct yellow 24 and Direct yellow 48.

4.Direct yellow RL has high directness to cellulose fiber and high dyeing rate. With a small amount of inorganic salt,it has a high dye uptake rate.

5.There is no aggregation in the dye bath at 130 degree.The PH value pf the dye bath is wide and the cellulose dye has a good uptake rate under acid conditions.

FAQ

What is Direct Yellow RL?

Direct Yellow RL, also known as Direct Yellow 86 is a type of synthetic dye commonly used in the textile industry to color cotton, silk, wool, and other natural fibers. It belongs to the class of direct dyes, which are water-soluble and can be applied directly to the fabric without the need for a mordant or fixative. Direct Yellow 86 is a bright yellow color and is known for its high color strength and good fastness properties, which means it resists fading or bleeding when exposed to light, water, or other environmental factors.

How does Direct Yellow RL work?

Direct Yellow RL is a direct dye that works by attaching itself to the fibers of the fabric through ionic and hydrogen bonding. The dye molecules have both positively and negatively charged groups, which allows the dye to interact with the negatively charged cellulose fibers of the fabric. When the fabric is immersed in a solution of Direct Yellow RL, the dye molecules dissolve in the water and diffuse into the fabric. The dye molecules then form strong bonds with the fabric fibers, resulting in a permanent color change.

Direct Yellow RL is a water-soluble dye, which means it does not require a mordant to fix the dye to the fabric. The dye molecules are also relatively small, which allows them to penetrate deeply into the fabric, resulting in a uniform and vibrant color.

What is the advantage of Direct Yellow RL ?

Direct Yellow RL is a simple and easily-use dye that does not require a mordant or additional chemicals to fix the dye to the fabric.

Direct Yellow RL produces bright and vibrant yellow colors that are suitable for a wide range of fabrics.

Direct dyes like Direct Yellow RL are generally less expensive than other types of dyes, making them a cost-effective option for textile dyeing.

Direct dyes are generally considered to be more environmentally friendly than other types of dyes because they do not require additional chemicals like mordants to fix the dye to the fabric.

Direct dyes like Direct Yellow RL can penetrate deeply into the fabric, resulting in a uniform and consistent color.
