DOPE DYED
ZERO DYED SPINNING

"Zero-dyeing spinning" is an innovative, environmentally friendly textile technology. Its core lies in adding masterbatch (colored chip particles) directly during the fiber production stage, giving the fibers color from the moment they are formed, thus completely eliminating the traditional post-dyeing step. The main features and advantages of this technology include:

​

Extremely high environmental friendliness:

Completely avoids the large amounts of wastewater discharged during traditional dyeing processes (traditional methods may require 100-150 liters of water to produce 1 kg of fabric). It also reduces heavy metals, dyes, and other harmful chemicals in the wastewater, contributing to zero chemical residue.

Significant energy saving and carbon reduction:

Eliminates energy-intensive steps such as dyeing, washing, color fixing, and drying, reducing energy consumption and carbon emissions.

Safety and health:

Due to the absence of post-dyeing chemical processes, the fabric does not contain carcinogenic substances such as formaldehyde and azo dyes that may remain in traditional dyeing processes.

Simplified process:

Moving the dyeing process forward and integrating it into fiber manufacturing simplifies the entire textile production process and improves production efficiency.

High color fastness:

Because the color is formed inside the fiber, it typically has good color fastness. In short, "zero-dye spinning" represents a significant technological advancement in the textile industry's move towards green and sustainable development. It is one of the latest and most environmentally friendly production methods evolved from dyed fabrics, yarn-dyed fabrics, and yarn-spun fabrics.
