Appearance characteristics
All are natural white modified heterogeneous hairs. Hair tufts are composed of more than two fiber types. The bend is large or not obvious. There is oil and sweat. There are medium or coarse groups
4.2 Fine wool and semi-fine wool are evaluated based on fineness, length, oil sweat, coarse cavity hair, dry and dead hair content, and the lowest among the four indicators is A fixed and equal branch. Improved wool is graded based on length, coarse hair, dry and dead hair content, and the lowest of the two indicators is used to grade. Appearance characteristics are reference indicators.
4.3 The fleece is divided into lengths after trimming. 70% (by mass) or more of the length of special-grade wool must comply with these regulations. For the rest of the wool length, fine wool must not be shorter than 60mm, semi-fine wool must not be shorter than 70mm, and 70% or more of the length of first-class wool must comply with this regulation. It is stipulated that the length of the remaining wool shall not be shorter than 40mm (fine wool shall not be shorter than 40mm~50mm wool), and semi-fine wool shall not be shorter than 60mm (of which 60mm~70mm wool shall not exceed 10%); second-class wool must have 80% and above comply with this regulation. The length of the remaining wool shall not be shorter than 30mm for fine wool and 50mm for semi-fine wool. 4.4. Fine wool and semi-fine wool are classified according to fineness indicators. The average fineness must comply with this requirement. 4.5 Oil and sweat index of fine wool and semi-fine wool. The wool that meets these requirements shall not be less than 70% of the wool or fleece of this batch. 4.6 Improved wool with a rough, dry and dead hair content of less than 5% or a hair tuft length less than 40mm and an improved wool shape shall be treated as an out-of-class product and packaged separately.
4.7 improved black floral hair, regardless of color depth or grade, packaged individually. 4.8 Single flower hair (white flower hair), packaged separately. 4.9 Loose hair and off-cut hair are graded according to their fineness, length, oiliness, and appearance characteristics, and are packaged separately. 4.10 Head, leg, tail hair and other defective hair with useful value must be packaged separately and must not be mixed with grade hair. 4.11. Asphalt hair and paint hair must be wiped out, and it is strictly prohibited to mix them with wool. 4. Fine wool and semi-fine wool of grade 12 and above are not allowed to have weak knots in the middle of the pile. 5
Inspection method
5.1 Level quality inspection
5.1.1 Sampling quantity
Take 1 pack for every 20 packs, less than 20 packs will be counted as 20 packs, more than 100 packs For every additional 50 packages, add 1 package. If the quantity is less than 50 packages, it will be calculated as 50 packages.
5.1.2 Sampling method
Samples for grade quality inspection are taken by unpacking, and samples that are sufficient to represent the quality of this batch of wool are randomly picked from both ends and the middle of the wool bale. The total amount of samples in each batch shall not be less than 20kg, and the weight of samples taken from each sampling package shall not be less than 3kg. 5.1.3. Inspection
Divide the collected wool sample into three equal parts, one of which shall be inspected for grade quality according to this standard. If there are different opinions, another copy can be used for repeated inspection. Finally, the grade of the batch of wool is determined based on the average of the two inspection results, and the remaining sample is reserved for reference. 5.1.4 Fineness inspection
Inspection shall be carried out against the wool fineness standard sample. If there is any dispute, objective inspection shall be carried out according to GB10685. 5.1.5 Inspection of natural length of hair

Inspection according to GB6976.
5.1.6 Oil and sweat test
GB 1523-93
Sampling according to B6976, measure the length from the bottom of the hair clump to the end of the contaminated layer, and calculate the ratio of the natural length of ancient hair 5.1. 7. Inspection of coarse cavity hair, dry and dead hair content shall be carried out according to GB/T14270.
5.2 Metric Inspection
5.2.″ Sampling
In batch transactions, the sample collection of net gross metric inspection samples must be carried out at the same time as the raw wool is weighed one by one. Metric inspection samples are The drilling method is supported, and the ratio of the number of drilled wool packages is shown in Table 3. The total amount of samples in each batch is not less than 1.2kg. Table 3

5.2.2 Inspection
5.2.2.1 Use a 500kg weighing (gradation value 0.5kg) scale that has been calibrated to weigh this batch of wool one by one and record it. Package weight.
5.2.2.2 While weighing each package, drill holes and cut out the net gross rate inspection samples according to GB/T14271. The final inspection is required. During re-inspection or arbitration inspection, the net gross rate inspection shall be carried out according to GB6978
5.2.2.4 Calculate the net gross weight according to the following method: W--.xu\y
Wuzhong;w\net gross. Rate, %
Wn Total net weight of raw wool, kg,
W standard weight of net wool, kg.
The standard moisture regain of fine wool is 16%, semi-fine wool, improved wool The official moisture regain rate is 15%. 5.2.2.5 When the content of vegetable impurities in the net wool is less than or equal to 2%, no increase in the amount of net wool will be made; if the content of vegetable impurities in the net wool is greater than 2% or less than 4%, the rate is 1:1.5. Check and reduce the net wool content: When the content of vegetable impurities in the net wool is greater than 4%, the net wool content shall be inspected according to GB6977
While inspecting the net wool content, a professional fiber inspection agency shall Make and affix test marks on each package. 5.2.2.7 To determine the net gross amount at the time of purchase, instrument testing of the net gross rate should be actively promoted in areas where conditions permit. In other areas, subjective inspection methods can be used, but it should be frequently corrected by instrument test data. 6 Inspection Rules
6.1 The inspection is based on fleece.
6.2 Small batch trade at the grassroots level shall be inspected according to physical standard samples. 6.3 Wool of the same type, same count and corresponding count shall be packaged in batches. , Inspection is carried out on a batch basis. 6.4 For raw wool traded in batches (above 2000k), the grade quality inspection and measurement inspection shall be subject to the statutory notarized inspection system. A professional fiber inspection agency shall conduct pre-sales inspection and issue a quality inspection certificate. 6.5 If one party to the transaction has objections to the inspection results and requires re-inspection, he or she should apply to the original inspection unit within fifteen days after receiving the inspection certificate. The re-inspection must be done by the original inspection unit within fifteen days after receiving the re-inspection application. The sample preparation is carried out. If you still have objections to the re-inspection results and need to apply for a second re-inspection, you should apply for a second re-inspection to the same second-level professional fiber inspection agency in the administrative divisions of both parties to the transaction within 15 days after receiving the re-inspection certificate, and re-inspect according to the standards. After submitting the sample, the second re-inspection is the final re-inspection. The final re-inspection will be carried out within 15 days after receiving the application.
