The Effect of Fabric Structure and Ultrasonic Welding Process on the Performance of the Spunlace Surgical Gowns

This study investigates the effects of fabric properties and ultrasonic welding on the performance of surgical gowns. For this purpose, eight spunlace fabrics with different structural properties were provided. 100% polyester, 100% viscose, and their blends were used as test materials. First, the fabrics' thickness, breaking force, elongation at break, air permeability, drape behavior, and surface friction properties were investigated. Then the fabrics were sewn with the ultrasonic sewing machine. Afterward, the sewn fabrics' seam strength, air permeability, and drape behavior were tested. The results were statistically evaluated. A detailed comparison was made based on the data obtained. The higher the polyester content in the fabric, the higher the fabric strength, seam strength, and air permeability. However, viscose-rich fabrics have a softer feel and are easier to drape compared to polyester fabrics. Moreover, the sewing process leads to a reduction in the air permeability of the fabrics.
