Introduction
Analysis of the core content of the standard
| Technical elements | Requirements of this standard | Differences in traditional processes |
|---|---|---|
| Dust control | ≤5mg/m³ (on-site) | Usually 8-10mg/m³ |
| Grinding rate | ≥80% | No quantitative standard |
| Unit energy consumption | ≤320kW·h/ton | 350-400kW·h |
Detailed explanation of key technical requirements
4.1 Raw material control
It is explicitly prohibited to use hazardous debris such as medical waste, and raw cotton is required to comply with the GB/T 35932 grading standard. A typical case shows that in 2021, a company was investigated and punished for using recycled cotton, which resulted in excessive bacteria in its products.
5.2 Process innovation
For the first time, the speed of the net yarn machine and the parameters of the tire curtain were matched and written into the standard, solving the 30% yarn defect problem in the traditional process. After implementation by a company in Xinjiang, the product qualification rate increased to 98.7%.
Implementation suggestions
Equipment configuration plan
It is recommended to configure a combination of Mars detection device + dust removal system. A company in Anhui Province adopted it and the number of fire accidents dropped to zero the year after.
Quality control nodes
Establish a key process checklist:
- Cotton laying uniformity (tested every 2 hours)
- Gauze adhesion (sampling for each batch)
Standard evolution analysis
Compared with the 2008 version of the industry practice, this standard adds:
- Energy consumption limit indicator
- Digital production parameters
- Occupational health protection clauses
