FAMOUS VB

Famous VB is a unique high temperature stable acid buffer and core alkali neutralizer specially developed for use during process of polyester fiber/fabric. Famous VB can be used during heat setting, dyeing and reduction treatment. Famous VB is a high performance low foaming auxiliary which eliminates the need for any acid addition to the process bath.

ADVANTAGES

• It is a powerful acid buffer which is stable over wide temperature rage (30⁰c -200⁰c).

• Famous VB is a viscose Safe Buffer which does not damage or burn viscose component under normal condition of dyeing and printing process.

• It ensures & maintains consistent pH even at elevated temperatures encountered during the dyeing / print fixation of disperse dyes on polyester.

• It enables use of even those disperse dyes which are sensitive to alkali or reduction.

• It improves shade consistency and brightness of the shade.

• It is biodegradable.

APPLICATION

1. During core alkali neutralization at jet dyeing machine 0.5% to 0.75% Famous VB is suggested.

2. During printing of polyester with viscose or cotton 0.5% to 1% Famous VB is suggested to maintain required pH.

3. During dyeing of polyester 0.5 to 1.0 gpl Famous VB is suggested
