Continuous spinning of viscose filament yarns
1 Scope
This standard specifies the classification and labeling, technical requirements,
test methods, inspection rules and labeling, packaging, transportation, storage
requirements of continuous spinning of viscous filament yarn.
This standard applies to natural color viscous filament yarn which is produced
by the raw materials of cotton pulp, wood pulp or mixture of cotton pulp and
wood pulp, using the continuous spinning process, which has a linear density
range of 55.0 dtex ~ 335.0 dtex and the monofilament linear density of 2.0 dtex
~ 7.0 dtex. Other continuous spinning of viscous filament yarns can use it as a
reference.

3 Terms and definitions
The terms and definitions as defined in GB/T 3291.1, GB/T 3291.3, GB/T 4146,
GB/T 4146.1, GB/T 4146.3 apply to this document.
4 Classification and identification
4.1 According to the different matting agents during production, continuous
spinning of viscose filament yarn products are divided into shiny yarn and
matting yarn.
4.2 Product specifications are expressed by linear density (dtex) and the
number of monofilaments (f).
Example: For a filament with a linear density of 133.3 dtex and a monofilament
number of 30f, the specification is expressed as 133.3 dtex/30 f.
4.3 Product identification shall be based on product specifications, raw material
pulp used in production, gloss, production process.
Example: 133.3 dtex/30 f cotton pulp (bright) continuous spinning of viscose
filament yarn.
5 Technical requirements
5.1 Product grading
6.1.2.1 When the moisture regain of the specimen exceeds the predetermined
moisture regain, pre-conditioning is required. The pre-conditioning conditions
are as follows:
- The temperature is less than or equal to 50 °C;
- Humidity 5% ~ 25%;
- The time is greater than 30 min.
6.1.2.2 The standard atmosphere for humidity conditioning and test of
laboratory samples shall be in accordance with GB/T 6529.
6.1.2.3 Random inspection of the manufacturer can refer to Appendix B for
quick humidity conditioning.
6.2 Linear density
Take the specified length of sample according to GB/T 14343. Perform de-sizing
(washing), rinsing and drying according to the method B of GB/T 6504 before
testing; then test the linear density according to GB/T 14343.
6.3 Breaking strength and elongation at break
It is performed according to the provisions of GB/T 14344.
6.4 Number of monofilaments
It is performed according to the provisions of GB/T 14343.
6.5 Residual sulfur
It is performed according to the provisions of FZ/T 50014. Among them, take
the laboratory samples according to the provisions of GB/T 6502. After
removing tens of meters from the surface of the laboratory samples, cut the
filament yarns into pieces of about 2 cm. Mix them evenly. Put it into a ground-
mouth bottle to keep moisture and save for testing purpose.
6.6 Dyeing uniformity
It is performed according to the provisions of FZ/T 50015.
Among them, the evaluation rules for blue pattern stripes, bands, patterns and
light pattern stripes, bands and patterns are as follows:
a) The samples with blue pattern stripes, bands and patterns are regarded
as qualified products;
b) The samples with light pattern stripes, bands and patterns are regarded
R - Measured moisture regain rate, %;
A - The deviation rate of the average net mass of the package and the official
mass, %.
7 Inspection rules
7.1 Inspection type
The inspection types are divided into type inspection and exit-factory inspection.
Type inspection shall be carried out in the following cases:
a) During the specified periodic inspection;
b) When there are changes in production design, process, and raw materials
that may affect product quality;
c) When the results of the exit-factory inspection are significantly different
from the previous type inspection;
d) When the national inspection agency requires type inspection.
7.2 Inspection items
7.2.1 All items in Table 1 are type inspection items, wherein serial numbers 1 to
8 are exit-factory inspection items; the tests shall be carried out according to
the corresponding test methods as specified in Chapter 6.
7.2.2 The visual inspection items shall be inspected according to the
requirements of 5.4 and the test methods specified in this standard.
7.2.3 The mass difference shall comply with the requirements of 5.5 and shall
be implemented in accordance with the provisions of this standard.
7.3 Group-batching rules
Use periodic sampling to form an inspection lot within a certain range. A
production batch can consist of one inspection lot or several inspection lots.

the other items are sampling inspection. Laboratory samples shall be taken
according to the provisions of GB/T 6502.
7.4.2 All appearance items are inspected.
7.6.5 Evaluation rules
