check the pocket cloth pocket fabric(pocketing fabric) tail skew
1.Definition of latitude:
Usually refers to the weft (coil) direction of the machine (needle) fabric, the yarn from the side perpendicular to the selvage causes one or several bending phenomena in the full width range.
In a broad sense, the weft also includes the presence of one or more bows on the full width of the pattern, such as the pattern, the strip, etc. in the processing steps such as printing, jacquard, embroidering, and gold-plating. The latter are sometimes referred to as flower skews. The test method is similar.
2,the type of latitude: divided into bow, double bow, double hook bow, anti-double bow, hook bow and so on
Latitude = latitude / width * 100%
3.Determination of the latitude:
At the time of inspection, check each fabric for defects. When calculating the latitude, it is generally necessary to measure each time in the head, middle and tail of the cloth to reflect the change of the latitude in the longitudinal direction.
For each type of fabric, each factory forms its own method of operation according to its actual inspection conditions, and there is no clear plan. This should be improved as follows:
(1)The measurement should be carried out on the platform. Pay attention to the flat fabric and test the weft inclination without accidental tension to prevent the system error caused by the suspension measurement on the inspection vehicle.
For the new inspection vehicle, the gauge device is usually pressed and rotated on the cloth surface, and the fabric is blocked at the contact point to form a zonal arch.
