- Product Description
Printing & Dyeing Solid Potassium Formate — High-Purity Reducing Agent for Textile Processing
Printing & Dyeing Solid Potassium Formate (HCOOK, CAS 590-29-4) is a high-purity organic salt engineered for demanding textile applications. It has a purity of ≥98% and serves as an excellent reducing agent and dyeing auxiliary that immediately solves the most typical pain points in current fabric processing – equipment corrosion, irregular dye absorption, and excessive wastewater loads. Shanxi Zhaoyi Chemical Co., Ltd., founded in 1988 with over 30 years of experience and an annual production capacity of 150,000 tons, supplies this product to textile mills and chemical distributors worldwide.

What Makes This Product Different from Standard Industrial Grades
Generic industrial potassium formate is formulated for oilfield or de-icing applications. This edition is specially designed for the printing and dyeing business, with stringent control of impurities, which generic grades cannot meet.
Conventional choices like sodium sulfate or sodium chloride lead to large COD and BOD loads to the effluent, increase the possibility of equipment damage due to chloride ions and are often ineffective in processes with high liquor ratios. The product handles all three problems simultaneously.
Improved water solubility allows for high-concentration liquid formulations, which are crucial to low-liquor dyeing techniques that are becoming more popular with energy-efficient textile mills.

Core Performance Advantages in Textile Processing
Precise pH control
The product accurately brings the pH of the dye solution to the ideal range of 7.5-8.5. This precision boosts dyeing uniformity by 15%-20%, reducing batch-to-batch variability that leads to colour inconsistency.
Increased Dye to Fibre Bond
It enhances the binding power between the dyes and the textiles which in turn means that the colour fastness is improved and the washing fade rate is considerably lowered.This result is reproducible repeatedly for reactive, vat and dispersion dyes.
Shorter Cycle Times
Dye penetration improved, reducing overall dyeing time by 10%-15%. That efficiency increase translates into considerable capacity and energy savings during a month of production.
High temperature stability
The product is fully effective in high-temperature dyeing and does not decompose as other organic auxiliaries do under heat. It is well suited for polyester, cotton-polyester blends and other fibres requiring greater processing temperatures.
Environmental Bylaws
The low concentration of impurities causes COD and BOD of the effluent to be lower than the limits allowed by the industry. This helps you avoid environmental penalties and meet the increasingly stringent compliance requirements of clients in export markets.

Application Scenarios
Potassium formate powder 590-29-4 in solid form is primarily used across the following textile processing steps:
- Dyeing of cotton, linen, and chemical fiber fabrics — acts as a reducing agent and pH buffer throughout the dye bath
- Color-fixing treatment — strengthens dye-fiber interaction after dyeing to lock in color
- Dye liquor pH adjustment — stabilizes the bath at 7.5–8.5 for optimal reactive dye performance
- Printing mordant preparation — provides reliable reducing conditions for specialty printing formulations
- High-temperature dyeing processes — maintains chemical stability at elevated temperatures where other agents may break down
Potassium formate is also utilised in oilfield drilling fluids, as a masking acid in leather processing, road snow melting agents, cement early-strength additives and leaf fertilisers, in addition to textiles, showing its extensive chemical application.
