Sodium Alginate
Sodium Alginate is a water-swollen, cross-linked polymer that is a product of a simple chemical reaction between monomers. It is a great water absorber, as structurally, the hydrophilic groups are attached to its polymeric backbone. It is resistant to dissolution because of the cross-linked network chains. It is a white or yellowish powder which is odourless, tasteless & slowly soluble in water. It reacts with calcium salt to form a thermo-irreversible form, because of which it is widely used in molecular gastronomy.
textile grade sodium alginate is an ideal thickener in reactive dye printing as it can not react with reactive dyes,as a water-soluble polymer,sodium alginate can be easily dissolved in water to form a viscous solution,in the printing and dyeing industry,sodium alginate has good washing out,high paste off rate,the film formed after printing on fabric has certain adhesion and flexibility,it does not react with dyes and other auxiliaries,the film formed after the film even after baking or bigh-temperature steam,it will be easily removed in the washing process,so that the hand feeling of the fabric is soft -
Sodium alginate use�? 1. In printing and dyeing industry, sodium alginate has unique properties, print out pattern bright-coloured, line is clear, the color yield high, colour and lustre is uniform, ink the drying speed is fast, easy desizing, permeability and feel is the best. Middle and low viscosity sodium alginate are suitable for dyeing and printing requirements.
printing sodium alginate very suitable for flat bed and rotary screen printing and handle printing Advantage: 1ã??High purity and stability. 2ã??Good filtration, high permeability rate. 3ã??Easy to color and good washing out. 4ã??The pattern is clear and bright. welcome to contact me !

It has been a long history that sodium alginate is used in starching, finishing and printing ,mainly printing .It ,as a reactive dye printing agent, has a special property.During reaction of fiber and reactive dye, the dye is fixed in fiber and printing agent do not attend this reaction .Otherwise, the agent will be fixed in fiber and make it hard,fragile and bad color.If you use sodium alginate as a printing agent,it not only affects the dyeing reaction but also makes the product outline clear, color bright,feeling smooth.This agent is also suitable for cotton,wool,silk and synthetic fiber. Sodium alginate advantage: 1,High purity and stability. 2,Good filtration, high permeability rate. 3,Easy to color and good washing out. 4,The pattern is clear and bright.
