Structural Count
Weft yarn count per unit of length in a woven fabric. Loom settings determine picks per centimeter by controlling the speed of the take-up motion relative to the insertion rate. The measurement ends at the count of the filling yarns along the warp direction.
Counting Method
Verification occurs by using a calibrated magnifying glass or a pick counter to count the yarns across a specific distance. Multiple readings across the width of the fabric ensure that the density is uniform from selvedge to selvedge. Variation in this count alters the weight and the cover of the textile.
Machine Calibration
Mechanical adjustments to the loom gear ratio or electronic control systems set the desired density during the weaving process. If the loom operates with too few yarns, the fabric becomes loose and may fail strength tests. Excessive density can cause yarn breakage or fabric stiffness during processing.
Commercial Standard
Specifications for bulk orders always include a target count and an allowable tolerance range. Quality inspectors check these figures against the approved master sample before authorizing a shipment. Maintaining consistent density is essential for matching the color and drape of different production lots.
Correct pick density is necessary for meeting the physical performance requirements of the cloth.
