GB/T 9337-2009Disperse dyestuffs - Determiation of dye-uptake at high temperature dyeing (English PDF)

Foreword

This standard replaces GB/T 9337-2001 "Determination of disperse dye color temperature rate." This standard and GB/T 9337-2001 major changes are as follows.

--- The standard name be changed to "disperse measured color temperature dyeing rate";

--- On the validity of the standard reference again to confirm;

--- Modify the presentation method for determining the content. The standard proposed by China Petroleum and Chemical Industry Association.

1 Scope

This standard specifies the method for determination of disperse dye color temperature and relative color yield on the polyester fiber.
