Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard is the FZ/T 50010.4-1998 "a species of viscose fiber pulp cellulose content determination" amendment.
Instead of the standard FZ/T 50010.4-1998, compared with the original standard, in addition to editorial changes, the major technical changes are as follows:
--- The original scope of cotton pulp, cotton pulp wood pulp extended to wood pulp, bamboo pulp, hemp pulp, etc. (see Chapter 1);
--- Delete a chapter laboratory atmospheric conditions (see the 1998 edition Chapter 3);
--- Standard chapter references into normative references, and adds 1 GB Part textile material properties and test/T 3291.1 "
Score: fibers and yarns ", GB/T 3291.3" textile material properties and test - Part 3: General ", GB/T 4146.1
"Textiles chemical fiber - Part 1: generic name" (see Chapter 2, 1998 edition of Chapter 2);
--- Increase Terms and Definitions chapter (see Chapter 3);
--- Chapter reagent into reagent and material (see Chapter 5, Chapter 5 of the 1998 edition);
--- Test sample preparation into a Chapter General, preserve the contents of the original sample preparation and test environment go In this chapter, the term "temperature (20 ±
1) ℃; relative humidity (65 ± 3)% "to" temperature (20 ± 2) ℃ "(see Chapter 7, Chapter 7 of the 1998 edition);
--- Replaced by the following test procedure (see Chapter 8, 1998 edition of Chapter 8):
a) "with flat glass rod carefully stirring 2 ~ 3min" to "flat head with a glass rod and stirred carefully for about 30 laps 30s";
b) "Be careful stirring for about 1min" to "carefully stirred for 10 laps around 10s";
c) "Be careful stirring for about 1 ~ 2min" to "careful stirring for about 12 laps 12s";
d) "and then vacuum suction filtration slowly" to "open the vacuum suction filtration allowed to slowly";
e) "the previous washes each wash the filter that is added when the new lotion to do," to "the previous washes each wash the filter to make the
When that is added to the new lotion and flip the sample was washed to spread evenly, ";
f) All "(20 ± 0.2) ℃ distilled water" was changed to "(20 ± 1) ℃ distilled water";
--- Modifying the formula (1) (see Chapter 9, Section 9 of the 1998 edition).
The standard proposed by China Textile Industry Association.
This standard by the Shanghai textile industry technical supervision of the centralized.
This standard was drafted: Yibin Long Yi pulp limited liability company, the Shanghai textile industry technical supervision, Yibin Si Liya Group Co.
Company, People's Republic of China Shanghai Entry-Exit Inspection and Quarantine Bureau.
The main drafters of this standard: Xue Qin, Huang Jun, Xia Jian Qin, Li Li, Zhu Hongkun, Zhou Zhen Germany.
This standard replaces the standards previously issued as follows:
--- FZ/T 50010.4-1998.
Viscose fiber pulp
A species of cellulose content determination
1 Scope

3 Terms and Definitions
GB/T 3291.1, GB/T 3291.3 and GB/T 4146.1 and define the following terms and definitions apply to this document.
3.1
A species of cellulose α-celulose
Cellulose by 17.5% sodium hydroxide solution (20 ℃) 45min after treatment the degree of polymerization of the cellulose does not dissolve in the higher part. Also known as
α- cellulose.
Principle 4
At 20 ℃ with sodium hydroxide solution of 17.5% viscose fiber pulp, and then washed with 9.5% sodium hydroxide solution, and finally washed with water
Washed, dried, weighed, whereby the content of its Class A cellulose. Expressed as a percentage.
5 Reagents and materials
5.1 concentration (17.50 ± 0.15)% sodium hydroxide solution: the analytically pure solid sodium hydroxide dissolved in an equal amount of new boiling cooling are not just
Carbon dioxide-containing distilled water, allowed to stand for 5 to 10 days, to the residue and the deposited sodium carbonate. Then siphon the supernatant was aspirated. With a dense
Meter measured density at 20 ℃, according to the measurement results, adding an appropriate amount of carbon dioxide-free distilled water diluted, adjusted to the desired concentration
Sodium hydroxide solution (17.50% sodium hydroxide solution at 20 ℃ density of 1.192g/mL).
5.2 concentrations (9.50 ± 0.15)% sodium hydroxide solution: prepared in the same 5.1.9.50% sodium hydroxide solution at a density of 20 ℃
1.103g/mL.
Note: Use only analytical reagent, and use only distilled water or water of equal purity.
