Effects of Defective Spinning Cans on the Performance of Spinning Machinery

Effects of Defective Spinning Cans on the
Performance of Spinning Machinery
2
Introduction

• 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.

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

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

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

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.

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

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.

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!
