In textile dyeing and finishing, pH control is critical for dye uniformity and fiber strength. To lower the pH of dye baths, many mills rely on strong acids like glacial acetic acid, hydrofluoric acid, or phosphoric acid. But these traditional acids have clear downsides. Acetic acid is flammable and volatile. Hydrofluoric acid is highly corrosive. They also have high COD and BOD values. This creates safety risks and adds to wastewater treatment costs.
TEXNOLOGY®UB bio‑acid from Lianzhuang technology offers a better alternative. It works as a pH regulator for dyeing processes. It effectively replaces most high‑concentration acids like acetic acid and hydrofluoric acid. It balances both environmental performance and pH adjustment efficiency.
Core advantages of TEXNOLOGY®UB bio‑acid
1. No irritating odor, non‑flammable
TEXNOLOGY®UB bio‑acid has no sharp smell. Workers do not suffer from inhaling unpleasant fumes. Unlike glacial acetic acid, it has no flash point, no corrosivity, and does not burn. It is not classified as a dangerous good. This makes storage and transport easier. It lowers accident risks and insurance costs for your mill.
2. Extremely low COD and BOD
TEXNOLOGY®UB bio‑acid has a COD of 23,000 mg/L and BOD of 6,100 mg/L. Compared to glacial acetic acid (COD 1,070,000 mg/L, BOD 760,000 mg/L), this represents a reduction of over 98%. This greatly reduces the burden on wastewater treatment. It helps mills cut treatment costs and improve environmental compliance.

3. Excellent performance and safe storage
TEXNOLOGY®UB bio‑acid performs similarly to 84% acetic acid. It meets the pH adjustment needs of textile dyeing processes. It does not evaporate or corrode. Its storage stability is better than glacial acetic acid. It adapts well to temperature changes.
TEXNOLOGY®UB bio‑acid is becoming the ideal choice for replacing traditional strong acids in dyeing and finishing. It offers no odor, non‑flammability, low COD/BOD, and superior safety. As a stable pH regulator, it helps mills achieve safer and more sustainable production.
