Foreword

This standard is the FZ/T 51001-1998 of amendments. Instead of the standard FZ/T 51001-1998 "viscose fiber pulp." This standard FZ/T 51001-1998 compared to the main changes are as follows. --- Adds a chapter of terms and definitions; --- Canceled prosperity viscose fiber, viscose silk with cotton pulp strength quality index assessment; --- Cancel the intrinsic viscosity of the assessment project; --- Cotton pulp viscose filament quality index of canceled series classification, kinematic viscosity unified with the control center value, adjusting a species Cellulose, whiteness assessment indicators; --- Viscose staple fiber cotton pulp quality indicators, the dynamic viscosity with a unified control center value, adjust the brightness, response performance, large dust Assessment indicators angstroms; --- Classification has been modified wood pulp by N1, N2, NH three series is amended as N1, N2 categories, the corresponding assessment index values as Adjusted, where with the dynamic viscosity control center value; --- Assessment ash canceled (525 ± 25) ℃ when the evaluation index, uniform application of indicators (725 ± 25) ℃ for examination; --- Iron content of units unified mg/kg; --- Resin content, pentosan content as the two types of test items. The standard proposed by China Textile Industry Association. This standard by the Shanghai textile industry technical supervision of the centralized. This standard was drafted.
