Products and Recommended Use
Borregaard LignoTech dyestuff dispersants are recommended for Disperse, Vat, Reactive and Acid dyes.
|Disperse dyes||Typically offered in paste (liquid) and powder form. Classified by energy level. Usually require a primary dispersant.|
|Vat dyes||Typically offered in paste (liquid) and powder form. Vanisperse CB is an ideal dispersant for liquid vat dyes.|
|Reactive dyes||Reactive dyes have traditionally been standardised with naphthalene sulphonates. Ultrazine NA is popular in this application, due to its purity and low staining properties.|
Our dyestuff dispersants are used either alone or in blended formulations to meet the specific requirements of a customer’s operation. The choice of dispersant(s) is dyestuff and process dependent.
Primary dispersants, such as Ufoxane 2 , Dynasperse LCD and Vanisperse CB are mainly used to enable dyeing performance at higher temperatures.
Secondary dispersants, like Ultrazine NA, Borresperse 3A and Borresperse NA are used for milling and standardization. Ultrazine NA has a very low insolubles and calcium content and is among the least staining of Borregaard LignoTech’s products.
Milling with dispersant combinations/blends is an effective technique to reduce cost. The combination of a primary dispersant along with Borresperse 3A or Borresperse NA at a ratio of 1:1 to 1:3 is recommended.
