  • What will influence cationic dyes in dyeing


    The cationic dye has a large affinity for acrylic. When dyeing, it spreads slowly due to fast adsorption, which is prone to dyeing uneven phenomenon. Once the dyeing is incomplete, it is difficult to correct it by extending the dyeing time. When dyeing the cation dye, in order to obtain a uniform dy Read More
  • What is the leveling agent for cationic dye


    The sustaining agent is often added to the dyeing of cations to reduce the upper dye rate and obtain a uniform dyeing effect. The sustained dye dyes of cationic dyes include cationic sustained dyeing agents and anion -ion slowly dyeing agents.Catalogeny -dye is the most commonly used slow -dye dye i Read More
  • What are the influencing factors of cationic dye dyeing


    1. TemperatureTemperature is an important factor in controlling uniform dye. When acrylic dyeing with cationic dyes, there is very little dye below 75 ° C. When the vitrification temperature (75-85 ° C) of the dyeing temperature reaches the fiber, the upper dye rate of the dye increases rapidly. The Read More
  • How to dye polyester (ECDP) fiber?


    In the ordinary PET polymerization process, adding a small amount of the fourth monomer can produce the normal temperature and pressure dyeable polyester ECDP. This is mainly due to the introduction of polyethylene glycol flexible segments in the PET macromolecular chain, which makes the molecular s Read More
  • Several dyeing methods of acrylic fiber


    Under normal circumstances, a reasonable dyeing process can be formulated. Common dyeing methods include constant temperature rapid dyeing method, saturated dyeing method and ordinary dyeing method. Constant temperature rapid dyeing method refers to dyeing at a temperature above the glass transition Read More
  • What is cationic dye?


    Cationic dyes are a kind of textile dyes, also known as basic dyes and basic dyes. Dissolved in water, it is in cationic state. Cationic dyes are soluble in water and ionize in aqueous solution to generate dyes with positively charged colored ions. The cation of the dye can combine with the acidic g Read More
  • A large acrylic fiber manufacturer in Peru


    Background: A large acrylic fiber manufacturer in Peru, before used the products which is internationally renowned brands, and has very strict requirements for dyes. There demand is three container of cationic black dyes each year, and they are increasing year by year.Challenge: The cationic dye required is a color mixed product. One of the raw materials is not stable, and it is prone to agglomeration when exposed to moisture, which affects the accuracy of the dosage, but this raw material is indispensable. In addition, bulk cargo is generally shipped by sea, and the route to Peru generally takes around 30 days, which increases the possibility of caking. Read More
