How to Control and Improve Problems in the Dyeing Process of CD-Type Cationic DyesCD-type cationic dyes can dye acrylic fibers at 100°C and CDP (cationic dyeable modified polyester) at 125-130°C.However, these dyes are relatively prone to color stains and uneven coloring.Let's discuss how to avoid t Read More

Points to Note in Actual Production of SD-Type Cationic DyesSD-type cationic dyes are dyes specifically designed for particular fibers and processes. Their key characteristics are their "disperse" nature and relatively wide chemical mixing temperature range. Dye Type and CharacteristicsSD-type cat Read More

The Impact of Solvent Dye Solubility on InkDifferences in the solubility of solvent dyes directly determine the performance, stability, and final application results of inks. The specific impacts are as follows: 1. Ink Stability and Shelf LifeHigh solubility: The dye dissolves completely and stably Read More

Storage and Management of Chemicals in Dyeing and Printing EnterprisesTable of ContentsXinhua News Agency, Dhaka, October 15 (Reporter Sun Nan) -- According to Bangladeshi media reports on the 15th, the death toll from the fire at a garment factory and chemical warehouse in Dhaka, Bangladesh's capit Read More

Solvent Dyes vs. Solvent-Free Dyes In the world of color, dyes are not all the same. Based on their solubility characteristics, they can be broadly divided into two categories: solvent dyes and solvent-free dyes (usually water-soluble dyes). The key difference between the two lies in the medium in w Read More

Why Choose Our Highly Washable Disperse Dyes？I. Analysis of the Factors Contributing to Price DifferencesThe price advantage of Indian dyes stems primarily from the following factors:Raw Material and Production Costs: Using standardized dye intermediates, the production process is relatively simple, Read More

Does disperse dyed polyester require reduction cleaning?1. IntroductionPolyester is a synthetic fiber primarily dyed with disperse dyes. These non-ionic, poorly water-soluble dyes diffuse into the hydrophobic polyester polymer at high temperatures (120-130°C). While the dye molecules within the fibe Read More

The Role and Precautions of Sodium Hydrosulfite in Dyeing Role of Sodium Hydrosulfite in Dyeing Sodium hydrosulfite, also known as保险粉 in Chinese, plays a crucial role in the dyeing process. Firstly, it acts as a powerful reducing agent. In the dyeing of vat dyes, these dyes are insoluble in water in Read More

The Principle of Vat Dye Printing ProcessVat dyes are a unique class of dyes widely used in textile printing due to their excellent color fastness and durability. The printing process of vat dyes relies on reduction–oxidation (redox) reactions, combined with proper printing techniques and after-trea Read More
