Degree of Opening and Its Progression
topic
The degree of opening is measured as specific volume (cm³/g) and follows a logarithmic curve along the blowroom line. Research by Artzt, Schenek and Al Ali shows the curve flattens toward the end, indicating diminishing returns. The optimal blowroom line should end at machine No. 3 or 4; subsequent machines yield only marginal improvements at the cost of material stressing, fibre loss, and increased neppiness.
Role
Understanding the opening progression curve is essential for designing efficient blowroom lines. It guides the principle that modern high-performance lines use only 4 machines (bale opener, pre-cleaner, blender, fine cleaner) rather than longer conventional lines.
