The standard covers the classification, technical requirements, test methods and quality assessment of yak wool, providing a scientific basis for the production, trading and processing of yak wool.
2. Comparative analysis of standard frameworks
| Standard dimensions | GB/T 12412—2007 | GB/T 12412—2024 |
|---|---|---|
| Definition of terms | Definitions of some impurities and net down rate are not clarified | New terms such as impurities and net down rate are added |
| Technical indicators | Technical requirements are relatively general | Refined to key parameters such as average diameter and roughness content |
| Test methods | Some test methods are not clarified | Newly added requirements for sample preparation of combed yak wool laboratory |
3. Interpretation of the core content of the standard
3.1 Definition of terms and product classification
Yak wool refers to fibers with a diameter of 35 μm or less obtained from yaks, including four types: extra-fine, fine, coarse and extra-coarse. According to color, it is divided into white yak wool, green yak wool and purple yak wool.
3.2 Technical requirements and quality assessment
The technical indicators of combed yak wool include average diameter, coarseness content, etc., among which the coarseness content is defined as the percentage of the mass of yak hair fibers that have not been completely removed to the total mass. The clean cashmere rate refers to the percentage of clean cashmere mass after removing impurities.
4. Implementation suggestions and precautions
- Inspection rules: Yak wool is inspected for quality and weight in batches, including fiber category, quality characteristics and other items.
- Packaging mark: Clearly specify product name, color, model grade and delivery unit to ensure clear and traceable information.
- Transportation and storage: Use moisture-proof and corrosion-resistant transportation tools and store in a dry and ventilated warehouse.
