Mass Confirmation
Technical audits of finished textiles ensure that the fabric weight per square meter meets the contractual agreement. This GSM verification involves taking multiple circular samples from different points across the width of the cloth roll. These samples are weighed on a precision balance to determine the average mass of the material.
Audit Procedure
Processors perform these checks after the final finishing and drying stages to account for any shrinkage or chemical additions. The GSM verification confirms that the weaving density and yarn count have produced the intended fabric substance. In many Chinese export contracts, a deviation of more than five percent from the target weight triggers a price renegotiation.
Technicians must calibrate the scales daily and ensure the samples are cut with a specialized circular die to maintain precision. This step is a standard part of the pre-shipment inspection.
Quality Threshold
Consistency across the entire batch is more important than a single high reading. While a heavy cloth might seem better, a failed GSM verification indicates a lack of control in the loom settings or the finishing range. Buyers rely on this data to calculate the yield of garments they can cut from a single shipment.
