Characterizing bulkiness and hairiness of air-jet textured yarn using imaging techniques

Control of product characteristics during production is very important to achieve improvement in quality. This importance come into consideration in yarn texturing because of high demand for textured textiles. In this investigation, new methods are introduced for the determination of air-jet textured yarn's structure, applying computer vision and image analyzing techniques. Since the size, density and distribution of loops are very important factors in air-jet textured yarns,they are determined measuring yarn diameter, hairiness and torque indexes and applying imaging techniques. The measured features are successfully utilized in the proposed method to quantify texturing characteristics.
