01. The grey fabric is treated with pure NaOH 3% and surface-active detergent 1% before dyeing, at a temperature of 130°C for 60 minutes.

The pre-dyeing treatment method has a certain erosive effect on polyester fibers with a ratio of 1:10 to 1:15, but is highly effective in removing oligomers.

Beneficial for reducing "glow" in polyester long fiber fabrics and improving pilling in medium to short fiber fabrics.

Maintain dyeing temperatures below 120°C and employ an appropriate carrier dyeing method to reduce the production of oligomers.

And enjoy the same dyeing depth.

03. By adding a dispersant protective gum additive during dyeing, we achieve both even dyeing effects and prevent oligomers from settling on the fabric.

Tianchi.

After dyeing, the dye solution is rapidly discharged from the machine at high temperature, with a discharge time of 5 minutes. Due to the oligomers at temperatures between one hundred to one hundred and twenty degrees

Evenly distributed in the dye solution, it is prone to accumulate and precipitate on the dyed material below 100 degrees Celsius, but this approach has

Heavy fabrics tend to wrinkle easily.

05. Utilizing alkaline dyeing conditions can effectively reduce the formation of oligomers, remove residual oils from the fabric surface, but it is essential to select

Dyes suitable for coloring under alkaline conditions.

After dyeing, clean with a reducer, add 3-5ml/L of 32.5% (380Be) NaOH, 3-4g/L of sodium metabisulfite, at 70°C.

Process for 30 minutes, followed by cold rinse, hot rinse, and cold rinse, neutralized with acetic acid.
