Warping gathers yarns from a number of bobbins and wound them close
together on a reel or spool. From there they were transferred to a warp
beam, which was then mounted on a loom. Warp threads were those that
run lengthwise on the loom.
At warping, the goal should be to avoid missing ends. Number of thread breakages should not exceed seven per 10 million meters. This can be achieved by ensuring a top quality yarn package and by following the warping process parameters mentioned below :
At warping, the goal should be to avoid missing ends. Number of thread breakages should not exceed seven per 10 million meters. This can be achieved by ensuring a top quality yarn package and by following the warping process parameters mentioned below :
- Precise Creel Alignment
- Reliable stop motion on creel and on warping drum, so that broken ends are traceable for knotting.
- Minimum wobbling of warping beams.
- Uniform selvedge with good flanges.
- Yarns should by preferably warped on spindle driven machines to avoid thermal damage due to abrasion.
- Warping machines such as Benninger or Hacoba are preferable.
- Frictional drum should be kept in a polished state.
- Brake should be ver y efficient.
- Aluminium cast flanges should be used to get faulteless selvedges.
- Breakages rate should not exceed 0.3~0.5 breaks per 1000 m / 500 ends.
- For wider width looms, wider warping machines are preferred.
