FAST Fabric Assurance by Simple Testing System
topic
The FAST system measures four key mechanical fabric properties — extensibility, bending rigidity, shear rigidity, and dimensional stability — using simplified, robust instruments designed for practical use in fabric mills and garment manufacturing quality control rather than research-level precision, providing sufficient mechanical characterisation to predict fabric behaviour during garment making and to assess suitability for specific garment construction processes. The system generates a FAST profile chart plotting the measured properties against reference zones defining ideal mechanical behaviour for particular garment types, enabling immediate visual identification of fabrics that are too stiff, too extensible, dimensionally unstable, or prone to seam pucker and collar curl. The simplified measurement approach and low instrument cost make FAST widely adopted in commercial fabric finishing operations for production quality control.
Role
The FAST system provides the practical quality control handle measurement that commercial fabric finishers and garment manufacturers need to prevent costly manufacturing problems caused by incorrect fabric mechanical properties — identifying fabrics prone to seam pucker, fusing distortion, collar roll, and dimensional instability before they enter cutting and sewing operations where fabric defects cause expensive rework and garment rejection.
