  1. Effects of Defective Spinning Cans on the Performance of Spinning Machinery

  2. Textile mills aim to optimize yarn quality, but defective spinning cans can hinder this goal. Defective spinning cans can damage original sliver parameters and final yarn quality. Can defects can also impact the functionality of spinning machinery over time. Common types of can defects include problems in HDPE sheet welding, incorrectly fixed bottom plates, can tilting, wrong spring load, and sub-standard caster wheels. Using defective spinning cans can lead to various issues in the production process. Introduction

  3. PROBLEMS AT THE CARDING PHASE • Carding machines must be used with glitch-free spinning cans for optimal performance and longevity • Accidental can tilting can lead to hampered silver coils and quality, causing higher sliver wastage and deteriorating efficiency • Not selecting the correct spring load in spinning cans can result in greater unevenness in sliver coils, increasing CVm% and U% • Using sliver cans with jammed or damaged caster wheels can lead to labor fatigue, delays, and hindered transportation on mill floors

  4. PROBLEMS DURING BREAKER DRAW FRAMING • Inappropriate spring load of cans can lead to problems at the breaker draw frame - Increase in U% significantly impacts the overall quality of sliver • Lap Forming Machine receives sliver from breaker draw framing cans and prepares laps for combing • Erratic or unstable spring load of cans can cause rise in sliver weight in creel zone, leading to sliver stretching - Risks of breakage in creel zone increase with defective cans • More piecings due to defective cans result in adverse effects on lap quality, increased labor load, and significant loss of production time/quality

  5. PROBLEMS AT THE COMBING PHASE • Carded sliver vs. combed sliver: combed sliver is heavier and requires higher spring load in comber cans • Incorrect load setup leads to decreased fibre-to-fibre cohesion, increasing risks of sliver breakages • Higher volume of sliver breakages results in more piecings, labor loads, and faults in sliver • Inefficient comber machine performance due to sliver breakages • Defective spinning cans lack stability, causing tilting and non-uniform movements inside coiler system • Non-uniform can movements lead to increased U% and CV% of sliver, more entanglements, and coil damages

  6. PROBLEMS DURING FINISHER DRAW FRAMING • Fibre cohesion levels in combed sliver are low, which affects sliver strength. • Defective can springs with inaccurate spring load further impact sliver strength. • Insufficient spring load causes sliver to hang with its own weight, increasing sliver separation and stretch percentage. • The quality of the final yarn is compromised as a result. • The spring load of spinning cans directly affects the U% and CVm% of sliver. • Problems with spring load lead to thin faults, increased CV%, and more breakages in the speed frame creel zone. • The gap between the creel and the top coils of the sliver becomes higher in such cases.

  7. PROBLEMS AT THE ROVING PHASE • Incorrect spring loads in spinning cans can lead to issues in output quality and mechanical performance • Higher storage time of sliver in cans than necessary can result in greater unevenness and higher CV% (strength & count) • Roving quality decreases when spring load of cans is not at the required level • Problems arise in winding phase when spring load of cans is lower than needed • Proper spring load ensures greater assurance regarding sliver strength

  8. HOW JUMAC HELPS IN ELIMINATING THE PROBLEMS? • Jumac is an industry leader in sliver handling, offering advanced tools and solutions to prevent can defects and ensure optimal mill performance. • Cans, trolleys, and accessories are manufactured in-house, adhering to strict quality parameters. • A systematic and reliable method is followed for assembling cans at Jumac, minimizing can tilt risks. • Anti-static HDPE sheets and nylon caster wheels with SS frame ensure smoother can movements and easier operator handling. • It is crucial to source spinning cans from a reliable manufacturer and regularly inspect them for damages to prevent system compromise. • Malfunctioning cans can have a significant impact on the entire sliver handling system, which is unacceptable in today's competitive mill landscape.

  9. “Malfunctioning cans can result in the entire sliver handling system getting compromised – and in the increasingly competitive landscape of today, mills simply cannot afford that!”
