Environmental Aspects in Textile Industry: Ecological Hazards and Remedial Measures
A study on environmental impact of textile industry and its remedies
If spinning tension is greater than yarn strength in the Ring frame, then end breakage is occurred and also due to roller lapping.
A. Technical causes
- An insufficient twist in the yarn
- If traveler fly off
- Subbing thorough
- Stretched roving
- Faulty drafting roller setting
- Faulty traveler selection
- Excessive yarn tension
- Improper atmospheric condition
B. Mechanical Causes
- Faulty drafting system
- Worn out ring and traveler
- Faulty gear and wheels
- Worn out top rollers
- Faulty apron
- Spindle vibration
- Eccentric ring
