Yarn Testing

The yarn represents the outcome of the fiber processing or yarn manufacturing part of the fiber-to-fabric textile pipeline. Before the yarn, it is still possible, within certain limits, to take corrective action should problems or mistakes have occurred during the earlier processing stages. Once the yarn has formed, any corrective action is limited to yarn clearing, up twisting, and singeing. The properties of the yarn largely determine subsequent fabric manufacturing performance and efficiency (also sewing performance) as well as the properties, aesthetic and functional, of the fabric and end-product. Yarn quality control, and the associated testing of those yarn properties which determine the yarn quality, are therefore crucial in ensuring that the yarn meets the requirements of the subsequent fabric manufacturing stages as well as of the fabric and end product.

STEMart provides comprehensive yarn testing services to provide inspection reports that meet relevant regulations and international standards, thus proving the quality and safety of textile products.
