Textile Pretreatment Processes

Role

Determines success of all subsequent processes—inadequate pretreatment causing uneven dyeing (unlevel dyeing worth 10-20% of production rejected/downgraded), poor color yield (increasing dye consumption 15-25%), and finishing defects. Quality pretreatment achieving 95%+ wettability, residual wax <0.3%, pectin <0.5%, whiteness index >70 (for bleached goods) enables consistent, reproducible dyeing and finishing critical for meeting customer specifications and minimizing re-processing costs.
