Pb Buffer Solution

PB BUFFER SOLUTION PB BUFFER SOLUTION is a speciality chemical which acts as an acid buffer and dispersant for dyeing of polyester and its blends with cellulosics. Also, it can be used as a neutralising agent. GENERAL CHARACTERISTICS Physical Appearance: Clear brownship liquidIonic nature: AnionicpH of 10% solution: 2 - 4Miscibility: GoodStability to hard water and electrolytes: GoodCompatability : Good with anionic and nonionic products Properties Maintains a constant pH during the dyeing process.Reproducible dyeings even with pH sensitive and metal sensitive dyes.Addition of acids, acid salts or special dispersants is not necessary.Practically insignificant foam formation.Easy to handle.No obnoxious smell. APPLICATIONS For exhaust dyeing of polyester and polyester / cellulosic blends set the dyebath at 60o C with 1.2 ml PB BUFFER SOLUTION at pH 4.5 - 5.5. Run for 5 - 10 minutes, add dyestuff dispersion, run for 5 - 10 minutes further and continue dyeing as per usual method.The demand the textile industry for eco lables, e.g. certification according to is steadily growing. An important factor getting a certification according to is the pH value of the fabric which must lie between 4.8 and 7.5
