Foreword
This Standard was drafted as per the rules specified in GB/T 1.1-2009.
This Standard revised FZ/T 50010.13-1998 Pulp Board for Viscose Fiber –
Determination for Reaction Property.
This Standard replaced FZ/T 50010.13-1998; compared with the original standard, this
Standard has the major technical changes as follows besides the editorial changes.
--- Expand the scope from the original cotton pulp to the cotton pulp board, wood
pulp board, bamboo pulp board, hemp pulp board, etc. (see Clause 1 of this
Edition);
--- Change the Quoted Standard into the Normative References; and add GB/T
3291.1 Textiles – Terms of Textile Material Properties and Test – Part 1. Fiber
and Yarn, GB/T 3291.3 Textiles – Terms of Textile Material Properties and Test
– Part 3. General, GB/T 4146.1 Textiles – Man-Made Fibers – Part 1. Generic
Names. (see Clause 2 of this Edition; Clause 2 of 1998 Edition);
--- Delete the Clause on Laboratory Atmospheric Conditions (see Clause 3 of 1998
Edition);
--- Add the Clause on Terms and Definitions (see Clause 3 of this Edition);
--- Change the Clause on Reagents into Reagents and Materials; and Change the
“chemically pure reagents” into “analytically pure reagents” (see Clause 5 of this
Edition; Clause 5 of 1998 Edition);
--- Change the Clause on Specimen Preparation into Test General, which is divided
into two parts, the first part is sampling, the second part is test environment;
thereof, change “viscose preparation and determination for reaction property
shall maintain the following conditions including temperature of (20±1) °C,
relative humidity of (65±3) %; temperature on working point of (20±0.5) °C.” into
“viscose preparation and determination for reaction property shall maintain the
temperature at (20±2) °C.” (see Clause 7 of this Edition; Clause 7 of 1998
Edition);
--- Delete partial contents in the Clause on Viscose Preparation of [the viscose
required to be prepared shall contain cellulose of 3.3%, sodium hydroxide of 13%
(the adding amount of carbon disulfide shall be 44% of the absolute dry mass of
the specimen)]; reserve the clause on specimen mass and viscose preparation;
change the formula (1) (see 8.2, 8.3 of this Edition; 8.2 of 1998 Edition);
--- Change, in viscose preparation, “adding 5mL of carbon disulfide” into “adding
certain volume of carbon disulfide (recommended short-yarn cotton pulp board
Pulp Board for Viscose Fiber

3 Terms and Definitions
The following terms and definitions and those ones stipulated in GB/T 3291.1, GB/T
3291.3 and GB/T 4146.1 are applicable to this document.
3.1 Reactivity property
It indicates the reactivity index of the pulp board (cellulose), which is expressed by the
time difference used by the prepared viscose liquid passing through the filter hole with
7.2.2 During the determination of the reaction property, the liquid level shall be kept
uniform (250mm).
7.2.3 The determination of reaction property shall be performed under ventilation
conditions.
8 Test Procedures
8.1 Determination of specimen’s analysis moisture
It shall be performed as per the provisions of FZ/T 50010.2.
8.2 Specimen mass
Calculate the specimen mass as per the Formula (1) (the specimen’s absolute dry
mass is 14.4g).
Where.
m – mass of required specimen, in g;
W – analysis moisture of specimen through humidifying, in %;
14.4 – specimen’s absolute dry mass, in g.
8.3 Viscose preparation
Take the specimen m through humidifying (convert into absolute dry mass of 14.4g,
accurate to 0.01g as per 8.2), place it into 500mL brown jar; add 361mL of sodium
hydroxide solution with temperature (20±0.5) °C, concentration of 13.7%. Install the
stirring rod of the electric stirrer into the bottle; the lower end of the stirring rod shall be
about 0.5cm~1cm away from the bottle bottom; stir the specimen into paste state at
