Fabric Inspection Guide

Fabric quality control involves the control of a series of characteristics, such as dimensional stability, shade uniformity, colour stability at fusing and ironing temperatures, light and stain removal fastness, weft squareness, consistent tensile strength, wear resistance, resistance to seam sliding pressure. Finishing products must not hinder fusing, and must not cause fabric stripiness and creases; selvedge must be regular, not too loose, not too tight or too large.
To make these controls easier Italian inspection machine makers offer a series of options, suitable both for woven and knitted/elasticised fabrics. Programmable automatic winding machines are also offered for cutting optimisation. An interesting development is a final control for measuring and controlling colour directly on any type of inspection table for any type of textile product. Thanks to an advanced system of colorimetric quality control an exact interpretation and evaluation of the readings is provided. Advantages include automatic calculation of tolerances, instrumental control of colour differences (center/selvedges, header/end), no need of tests for sample sets, and speeding up of the control process.
