Major Warping Defects- On Sectional warping
Snarlings and Overlappings
These are caused by irregular yarn tension. The broken end is not tied-up by the operative with the yarn end on the drum.
Different lenghts of sections, High Wastage Rate
This is caused by over-or-under warping of sections, untimely laying of lease cords due to faulty operation of the counter and the carelessness of operative.
The sections overlap each other or there is an excessive distance between them. This is caused by support improperly set and the careless of warper operative.
Stripiness in the Warp
This is caused by improper mixing of raw material
Irregular winding on the warper's beam which is displaced towards one end. This is due to improper position of the weaver's beam in warp beaming.
Different lenghts of Ends
It also includes irregular distribution of the section in the weaver's beam width. This is caused by improper fixing of section ends to the weaver's beam.
Excessive or insufficient number of yarn ends in the warp
This is caused by improper calculation at gaiting.
Warp Beaming on a defective weaver's beam
This is caused by carelessness of the assistant foreman and the warper operative.
Incorrect Laying of lease cords, or their absence in some sections
Again this is caused by carelessness of the warper operative.
