1. What is Dope dyed yarn ?

a) Properly known as new dye method yarn

In conventional polyester yarn production, the raw material (polyester pellets) is melted and spun, followed by the dyeing process. Dope dyed yarn, however, incorporates pigments or dyes during the melting and spinning process. This skips the traditional dyeing process,

leading to substantial reductions in:

– Water consumption

– Energy consumption

– CO₂ emissions

b) Outstanding Color Fastness

Think back to childhood days of mixing multiple colors of clay until they blend into a single color. Using a similar method, pigments or dyes are kneaded into the yarn during production.

This integrates the color with the fiber, resulting in yarn that is less prone to fading, discoloration, and bleeding compared to conventional polyester yarns.

c) High-Quality, Uniform Fibers

Skipping the dyeing process, which often involves substantial water usage, results in high-quality and uniform fiber products.

By eliminating the potential degradation of quality during the dyeing process, as well as the stress and damage that yarn undergoes in traditional dyeing, dope dyed yarn offers superior consistency with minimal damage.

Yarn is surprisingly delicate, and it can degrade due to processes involving human touch and environmental changes. During the dyeing process, the yarn is immersed in cold water and subjected to heat to reach the high temperatures necessary for dyeing. After dyeing, the temperature decreases to a level where people can touch the yarn, and the soaked yarn is placed in a drying machine.

These are typical stresses and damages incurred by yarn in the dyeing process. However, this is not the case with the dope dyed yarn. While it might not be easily visible when looking at the yarn alone, the advantage of dope dyed yarn is that it results in less damage reflected in the final products such as garments and fabrics.
