Can You Dye Viscose And Elastane Fabric?

The question is “Can You Dye Viscose And Elastane Fabric?” The answer is Yes, we can dye viscose and elastane fabric. Viscose is regenerated cellulose fiber. It is a special fabric and it needs special care to dye the fabric. The 100% viscose fabric dyeing process and the Viscose elastane fabric dyeing process are nearly the same.

Viscose is normally used for layers of garments. Sometimes for gents. To get elastic properties, elastane is added to viscose fabric. Normally we use 5% to 10% elastane to viscose fabric to get better results. That is why no need to dye elastane parts in fabric. We dye only the viscose part.

Viscose and elastane are both types of fibers commonly used in the textile industry. Here’s a brief overview of each:

  • Viscose:
    • Viscose, also known as rayon, is a regenerated cellulose fiber derived from natural sources such as wood pulp. It is known for its soft and breathable qualities, making it a popular choice for clothing and other textile applications.
  • Elastane:
    • Elastane, also known as spandex or Lycra, is a synthetic fiber known for its exceptional elasticity. It is often blended with other fibers to add stretch and flexibility to fabrics, providing comfort and ease of movement.

Now, regarding dyeing these fabrics:

  • Viscose (Rayon):
    • Viscose can generally be dyed using a variety of dye types, including reactive dyes, direct dyes, and vat dyes. However, it’s important to consider the specific type of viscose fabric and any finishes it might have. Some viscose fabrics may have additional treatments or coatings that can affect the dyeing process. Always check the care label and follow the recommended dyeing instructions.
  • Elastane (Spandex or Lycra):
    • Elastane itself is generally not easily dyed because it is resistant to many types of dye. However, elastane is often used in blends with other fibers like cotton, polyester, or viscose. In such cases, the dyeability of the fabric will depend on the other fibers present. It’s important to follow the dyeing instructions for the specific fabric blend and consider the characteristics of the individual fibers.

When dyeing fabrics with a blend of viscose and elastane, it’s crucial to use a dye that is suitable for both fiber types. Additionally, consider the care instructions for elastane, as excessive heat or harsh chemicals may affect its elasticity.

Different ways of dyeing viscose and elastance fabric

Viscose and elastane fabrics are commonly used in the fashion industry for their softness and stretch. There are several ways to dye these fabrics, depending on the desired outcome and the dyeing method used. One common method is to use reactive dyes, which chemically react with the fibers to create a strong bond. Another option is to use disperse dyes, which work well with synthetic fibers such as elastane. Additionally, natural dyes such as indigo and madder can also be used to dye viscose and elastane fabrics, creating unique and eco-friendly colors. Ultimately, the choice of dyeing method depends on the specific requirements of the fabric and the desired outcome.


Viscose is a special fabric all over the world and lycra/elastane viscose fabric dyeing is also special. Viscose elastane fabric dyeing is a common process. But it is possible.
