100% Viscose Single Jersey Fabric Dyeing Standard Recipe

The 100% viscose single jersey fabric dyeing standard recipe is stated here. Viscose is such a sensitive fabric. So, the dyeing recipe and viscose dyeing process are also the most sensitive. Its recipe and dyeing process is different from the 100% cotton fabric dyeing recipe and dyeing process. At the same time, viscose is one kind of cellulose (Regenerated cellulose) fiber as cotton fiber.

100% Viscose fabric dyeing process

Viscose fabric dyeing is a process of coloring the fabric using dyes. 100% viscose fabrics are rejenareted celulose fiber fabric. The dyeing process involves pre-treatment, dyeing, and post-treatment steps. The pre-treatment step involves scouring and washing the fabric to remove any impurities. The fabric is then dyed using either disperse or sublimation dyes, followed by a post-treatment step to fix the color and ensure color fastness.

Terms:

  1. Pretreatment:
    • Scouring and Bleaching:
      • Scouring involves the removal of natural impurities, waxes, and any sizing agents present on the fabric. This is done to improve the dye absorption. Bleaching is carried out to achieve a clean and uniform white base, especially if the fabric is intended to be dyed in light or pastel shades.
    • Eco Scouring/Multifunctional Scouring Agent:
      • Eco-scouring agents are environmentally friendly chemicals used to replace traditional scouring agents. They effectively remove impurities while minimizing the environmental impact.
    • Oil Remover:
      • Oil remover agents are used to eliminate any residual oils or greases from the fabric. This step is crucial for achieving even dye penetration.
    • Anticreasing Agent:
      • An anticreasing agent is applied to prevent or reduce the creasing of the fabric during subsequent processing steps. It helps maintain the fabric’s smoothness and appearance.
  2. Dyeing:
    • This step involves immersing the prepared fabric in a dye bath. The dye molecules adhere to the fabric’s fibers, creating the desired color. Factors like dye type, temperature, pH, and duration of immersion play crucial roles in achieving the desired results.
  3. After Treatment:
    • Soaping:
      • Soaping is the process of washing the dyed fabric to remove excess or unfixed dye. It helps improve color fastness and prevents bleeding of colors during subsequent washes.
    • Fixing Agent:
      • A fixing agent, also known as a mordant, is used to enhance the fastness of the dye on the fabric. It chemically bonds the dye molecules to the fibers, making the color more resistant to fading.
    • Softening Agent:
      • After dyeing, a softening agent is applied to improve the hand feel and drape of the fabric. It imparts a soft and pleasant texture to the material.

These steps collectively ensure that the dyed viscose fabric meets quality standards in terms of color vibrancy, fastness, and overall appearance. Additionally, in recent years, there has been a growing emphasis on eco-friendly and sustainable dyeing practices, which consider the environmental impact of the chemicals used in the process.
