Cotton fiber quality is determined by various parameters such as:
- Fiber Maturity Index
- Fineness
- Micronaire (mic)
- Fiber Length
- Length uniformity
- Elongation
- Strength
3 Types of Cotton fiber testing is widely used in the spinning industry. These are:
- High Volume Instrument (HVI)
- Advanced Fibre Information System (AFIS)
- Fibre Contamination Tester (FCT)
| Type | Length (mm) | Mic. | Strength (GPT) | Trash (%) |
| S-6 | 27.5 – 29 | 3.5 – 4.9 | 28 – 29 | 2 – 3 |
| MCU-5 | 30 – 32 | 3.5 – 4.9 | 29 – 32 | 2 – 3 |
| DCH-32 | 34 – 36 | 2.8 – 3.8 | 33 – 36 | 3 – 4 |
