All of these lead to conditions which are favorable to end breakage, an occurrence which should be minimized.
Occasionally during weaving, one of the many warp ends may break.
It is essential that the warp threads should not be damaged by the rapiers and that the rapier head should meet clearly for weft transfer. By eliminating guides, there is the advantage of reducing end breaks due to knot failure
The result of the trial operation shows that weft crackiness and end breakage decrease greatly.
Polyester Cotton Blended Fabric has good comfortability and high product added value, produce difficulty is existing for high broken ends percentage by using domestic equipment.
If the yarn contains too much size by weight, it will tend to be brittle and, as a result, an excessive number of end breaks will occur.
These breakage could be the result of excessive tension or, perhaps, a weak spot in the yarn.
This resulted in endless breakages in the yarn.
If the yarn contains little or no size, then none of the benefits of sizing the yarn will be realized and again there will be excessive end breakage.
When a break occurs the fault zone can be retrieved from storage and this enables higher warping speeds to be used.
In any event, if this break were to go undetected, the broken end would eventually be absent from the fabric, resulting in a defect in the fabric.
During filling insertion a yarn can possibly break or the filling supply package might run out of yarn.
New Function of Weft Broken-end Stop Motion in Shuttleless Loom
It is necessary to have a stop motion since a good warp should not contain many broken ends.
testing methods for breaking force and elongation at break of yarn : single-end method
These form a protective coating over the yarns and keep them from chafing or breaking during weaving.
Time Warp~ A ribbon is displayed and cut into pieces, then visually restored.
