Cationic pigment paste for fabric dyeing|keep improving
Fabric dyeing ways are divided into dyestuffs dyeing and pigment dyeing.
Fabric pigment paste dyeing is a special dyeing process that pigment particles is fixed on the fabric fiber surface by the action of matched adhesive in the water-based system.
Fabric pigment paste dyeing is finished in the aqueous system liquid, and pigment can't be dissolved in water, the dyed water is also easily separated. So it is environmental safety. Shanghai Caison Color is just a water based pigment paste manufacturer which is professional researching fabric pigment dyeing.
Fabric dyes dyeing is that fabrics are put into the dyeing liquid which is prepared by dyestuffs fully dissolved in water. The dyes particles react chemically with the fabric fibers under the high temperature and long time conditions. Textile adsorbs the dyes, and the chemical reaction to achieve the purpose of dyeing. Dyes can carry out the depth dyeing for fabrics, hand feeling is also very well, but the dyed wastewater is hard to separate. So dyes wastewater pollution and treatment is a world recognized difficult problem. Different kind of textiles also need different types dyestuffs finish the dyeing. However, pigment dyeing is suitable for wide range of fabrics, pigment paste dyeing process is simple relative to the dyes dyeing.But the fabrics should need grafting before dyeing. Hand feeling of pigment paste dyeing is worse than dyes dyeing, fabric softening is needed after dyeing.
Because this kind of dyeing mechanism is ion-dependent van der Waals force for dyeing! And there are many factors that affect the ion micro-movement, so many of the technical problems of cationic dyeing have not been well resolved until now!
Technology Department of Shanghai Caion Color has always researched the cationic pigment paste dyeing, which has been five years now. During the dyeing case in lab, the fabric which is dyed by cationic pigment paste, its hand feeling is better soft, because no grafting is needed. We are doing more experiments on different fabric dyeing , and hoping to improve the performance evaluation of more fabric cationic pigment paste dyeing. We sincerely hope that environmentally friendly cationic dyeing water-based pigment paste has a wider range of applications!
