Our textile grade Sodium alginate with the brand of Lotusea has three major features that are better than other paste materials.        

1. The pulp rate of color paste is extremely high and rheology, printing permeability, printing uniformity and hygroscopicity are all excellent; and
the paste film formed on the textile is soft and firm and the desizing will be easy even after going through baking.

2. The color paste has very strong permeability and uniformity, which can make reactive dyes very easily attach to the textile fibers, while the
paste itself does not react with the reactive dyes, and therefore it will not affect the printing process of the reactive dyes and the textile fibers,
completely avoiding the attachment of reacted color paste on the textile fibers which gives a hand feel of hardness, embrittlement, and
bad color.

3. The pattern color printed by the color paste is very fresh, with clear and bright outline and pattern, high color yield and good hand feel, and
the dyed textile is soft and elastic.

Choice of Lotusea sodium alginate can make your dyed and printed goods easily upgraded, and it is the most ideal partner of reactive dyes
and disperses dyes
