Dew-Retted Heilongjiang Line Fiber Processing Parameters for Ring Frames
Optimize wet ring frame trough temperatures to 72°C and hold draft ratios below 17 for Heilongjiang dew-retted line flax to limit end breaks.
Traveler Mass Selection
Spinning Load
Centrifugal force dynamics determine the physical interaction between the ring traveller and the spinning ring during the transformation of flax fibre into yarn. Traveler mass selection manages the friction heat and vibration levels produced at high rotational speeds to prevent yarn breakage. This process operates under specific mechanical conditions where the mass of the traveller must counterbalance the tension of the yarn as the bobbin diameter increases.
It defines the operational boundary of the spinning frame by limiting the maximum speed achievable before the heat generated at the contact point degrades the integrity of the flax fibres.
Engineering Constraint
Manufacturers calculate the required weight based on the count of the yarn and the speed of the spindle. Traveler mass selection follows strict guidelines in the mill documentation to ensure the friction between the traveller and the ring remains within a range that avoids thermal damage to the fibre. Operators adjust the weight to account for the increasing tension as the yarn package builds up from the base of the tube to the top.
Proper selection prevents the premature wear of ring surfaces while maintaining consistent twist levels throughout the entire spinning cycle.
Acceptance Protocol
Quality control records detail the technical specifications required for each lot of yarn produced on the spinning frames. Traveler mass selection undergoes verification against internal mill standards rather than buyer acceptance criteria because the choice directly influences the immediate output of the machines. The production log notes the weight of the travellers used for every frame run to ensure traceability across different batches of raw material.
Consistent adherence to these mass parameters allows a mill to maintain uniform yarn regularity while reducing the downtime associated with frequent end breakages during the spinning stage.
