Textile Chemistry
Acetic Acid 99%
Formula:
CH₃COOH
GOST/CAS:
CAS 64-19-7
Acetic Acid 99% (Glacial Acetic Acid) is a highly concentrated organic compound acting as a key reagent in the textile and light industries. The product is a colorless, transparent liquid with a sharp, characteristic pungent odor, completely miscible with water. Due to its high purity and optimal chemical properties, it is indispensable for precise pH regulation of processing media, dye fixation, and the finishing of textile materials made from natural, blended, and synthetic fibers.
Applications
pH Regulation in Dye Baths: Used to create and stably maintain an acidic environment when dyeing wool, silk, polyamide, and other fibers with acid, disperse, and reactive dyes.
Color Fixation and Intensification: Ensures deep penetration of the dye into the fiber structure and its reliable fixation, significantly increasing the brightness, shade saturation, and resistance of finished fabrics to wet processing and washing.
Neutralization After Alkaline Processing: Effectively and gently neutralizes residues of caustic soda and other alkalis on fabrics and yarn after mercerization, scouring, milling, or bleaching operations.
Textile Printing and Finishing: Applied in printing paste formulations and during final fabric finishing to improve the solubility of components, prevent spot formation, and impart softness to the material.
Key Advantages
High Concentration and Purity: An active substance content of ≥ 99% guarantees minimal product consumption per unit of output and eliminates the presence of foreign impurities that could distort the textile shade.
Gentle Effect on Fibers: Unlike strong mineral acids (such as sulfuric or hydrochloric acids), acetic acid acts gently without destroying the structure of even the most delicate natural fibers.
Eco-Friendliness and Biodegradability: The product is completely biodegradable, does not accumulate in the environment, and does not form toxic compounds, which significantly simplifies and reduces the cost of wastewater treatment.
Excellent Solubility and Compatibility: Mixes easily with water in any proportion and demonstrates excellent compatibility with most modern textile auxiliaries and surfactants.
Storage & Transportation
- Store in dry, cool, light-protected, and well-ventilated warehouses in tightly closed original packaging, away from oxidizing agents, alkalis, and combustible materials.
- Special Temperature Control: Given the freezing point +16.6℃, the product must be stored in heated rooms during the winter period at a temperature not lower than +18℃... +20℃ to prevent crystallization.
- Avoid exposure to direct sunlight, open flames, sparks, and high temperatures (the product is a flammable liquid).
- Transportation is carried out by all types of covered transport in strict accordance with the regulations for the transport of dangerous goods (belongs to Hazard Class 8 — corrosive substances).
- Guaranteed shelf life is 1 year from the date of manufacture.
