Inspection rules for grey yarn of cotton, man-made
fiber or their blend
1 Scope
This Standard specifies the terms and definitions, acceptance, sampling
quantity, inspection assessment, reinspection rules for inspection rules for grey
yarn of cotton, man-made fiber or their blend.
This Standard is applicable to acceptance and re-inspection of grey yarn of
cotton, man-made fiber, and other fiber or their blend.

3 Terms and definitions
For the purposes of this document, the terms and definitions defined in GB/T
sampling plan of GB/T 2828.1. The general inspection level is I. The acceptance
quality limit (AQL) is 2.5.
5.2.5 When the net weight of the package is less than 2t, take 2 packages
(boxes) for inspection. When it is 2t and above, take 5% of the total number of
packages (boxes), not more than 15 packages (boxes).
5.2.6 The number of tests for each acceptance item shall be implemented in
accordance with the relevant test methods or product standards.
6 Inspection assessment
6.1 The quality level of the acceptance items of the grey yarn is assessed
according to the requirements of the respective product standard (or
agreement). If the quality indicators of all assessment items are qualified, the
quality of the batch of products shall be accepted. If the quality indicators of an
assessment item is unqualified, the quality of the batch of products shall be
rejected.
6.2 For the yarn that has been heat-fixed and twisted (with a fixed-twist
temperature of 40°C and above), the breaking strength of the single yarn
(thread) is reduced by 5% according to the specified indicator.
6.3 In the inspection of package net weight of cheese yarn, when the moisture
regain is inconsistent with the electric heating oven and the bobbin moisture
meter, the moisture regain measured by the electric heating oven shall prevail.
6.4 The range of linear density deviation rate of singeing yarn is assessed and
graded based on the absolute value specified in the corresponding standard
plus 0.5.
6.5 The inspection of the net weight of the package shall be based on the weight
at the time of the regular moisture regain. When the actual moisture regain
exceeds or falls below the public moisture regain, it shall be converted into the
weight at the regular moisture regain. The specific inspection method shall be
implemented in accordance with Annex A. The allowable deviation of the
package net weight of cheese yarn (fixed weight) is -0.2% and less. The
allowable deviation of net weight of the package skein yarn and cheese yarn
(fixed length) (after removing the influence of the difference in the Tex series on
the weight) is -0.5% and less.
6.6 The yarn defect acceptance shall be carried out in accordance with Annex
B.
6.7 The forming appearance inspection of yarn is carried out in accordance with
the agreement between the two parties.
Annex A
(normative)
Acceptance of yarn package net weight
A.1 Sampling
Sampling is conducted according to 5.2.5 of this Standard, or according to the
method agreed by both parties.
A.2 Weighing and sample extraction
A.2.1 Weigh the gross weight and packaging material weight of each package
one by one. The cheese yarn needs to be weighed by the bobbin (tube).
A.2.2 Six cheese yarns are randomly selected from each package as a group
of specimens for moisture regain determination.
A.2.3 Randomly select skein yarns with a total weight of not less than 150g
from each package as a set of specimens for moisture regain determination.
A.3 Determination of moisture regain
A.3.1 The moisture regain of the yarn is determined by the oven test method,
which is implemented in accordance with GB/T 9995.
A.3.2 Moisture regain specimen of cheese yarn: Remove the outer layer of a
group of cheese yarn specimens by more than 6mm. Then strip the yarn (total
weight is not less than 150g) and weigh it as the specimen weight before baking.
Put it in the oven to bake till the constant weight. Then weigh it. Calculate the
moisture regain.
A.3.3 Moisture regain specimen of skein yarn: Weigh a group of skein yarn
samples directly as the specimen weight before baking. Put it in the oven to
bake till the constant weight. Then weigh it. Calculate the moisture regain.
When the moisture regain specimen weight is greater than 120g, it shall be
dried in baskets.
A.4 Calculation of package net weight
A.4.1 The net weight of the yarn in the package at the regular moisture regain
is calculated according to formula (A.1). If there are multiple packages, the net
weight of a single package shall be calculated separately. Calculate the average
net weight of the batch of specimens. The calculation result is rounded to two
