Foreword
FZ/T 01057 "Test Method for Identification of Textile Fibers" includes nine parts.
— Part 1. General Introduction;
— Part 2. Burning Behavior;
— Part 3. Microscopy;
— Part 4. Solubility;
— Part 5. Qualitative Observation of Color-production for Chloring and Nitrogen;
— Part 6. Fiber Melting Point;
— Part 7. Density Gradient Column Method;
— Part 8. Infrared spectrometry;
— Part 9. Birefraction.
This part is the fourth part of FZ/T 01057.
This Part replaces FZ/T 01057.4-1999 "Test Method for Identification of Textile Fibers
- Solubility".
Compared with FZ/T 01057-1999, 11 parts in the former standard are integrated to 9
parts presented in a new sequence. Part 5 "Dye and Stain Tests" and Part 11
"Comprehensive Method" in the former standard are canceled; the former part 6
"Qualitative Observation of Color-production for Chloring and Nitrogen" is re-located
to part 5; the former part 7 "Fibre Melting Point" is re-located to part 6; the former part
9 "Density Gradient Column Method" is re-located to part 7, and the former part 10
"birefraction" is re-located to part 9.
There are the following revisions to FZ/T 01057.4-1999.
1) Change the name of the standard to "Test Method for Identification of Textile
Fibers - Part 4. Solubility";
2) Add chapter "Normative References";
3) Add chapter "Test Report";
4) Integrate "Test Number" into chapter "Procedure";
5) Add the method for preparation of copper-ammonia solution in chapter
Test Method for Identification of Textile Fibers –
Part 4. Solubility
1 Scope
This Part of FZ/T 01057 specifies a test method for textile fiber identification -
solubility method.
This Part is applicable to qualitative identification for textile fibers.

FZ/T 01057.1 Test Method for Identification of Textile Fibers - Part 1. General
Introduction
3 Principle
A fiber may be identified by utilizing the different solubility property at different
temperature and in different chemical agents.
4 Reagent
The reagents to be used are analytically pure or chemical pure; they include.
concentrated sulphuric acid, concentrated nitric acid, formic acid, glacial acetic acid,
fluohydric acid, sodium hydrate, sodium hypochlorite, potassium rhodanate,
N,N-dimethylformamide, cyclohexanone, dimethylketone, phenol, tetrachloroethane,
1,4-butyrolactone, dimethylsulphoxide, dichloromethane, carbon tetrachloride,
tetrahydrofuran, cupric hydroxide, ammonium hydroxide (stronger ammonia water)
and acetic ether.
