Orco Buffer 14 Powder™ is a specially compounded buffer for use in nylon and wool dyeing to help control strike rates of most acid dyes.  Orco Buffer 14 Powder™ may be used in conjunction with various acid donor salts or acid exhaust methods.

Procedures

• Nylon             Use 0.5-1.0% Orco Buffer 14 Powder™ on weight of goods(owg ) to significantly slow strike rates when using dyes such as Orco Milling™ acid dyes.  Orco Buffer 14 Powder™ helps retard the first exhaust addition of acetic or formic acid promoting uniform and gradual exhausting of the dye.
• Wool              Use 0.5-1.0% owg Orco Buffer 14 Powder™ will slow down strike rates of various milling and neutral premetallized dyes.  Orco Buffer 14 Powder™  also performs a very important function of buffering excessive acid left over from carbonizing without the detrimental high pH shocks associated with soda ash or caustic soda.
