Testing lab
Testing Lab area supports Customers in the process of quality control of textile and non-textile materials, in defect prevention or resolution, in the study of materials and in certificates of compliance to tender specifications or sector regulations.

The analytical testing field of the Testing Lab area includes fibers, yarns, fabrics, garments and related accessories in textile, leather, plastic or metal.
High professionalism, instrumental equipment and accreditation system* allow Ritex to provide companies of the textile and apparel supply chain with a highly reliable service, both in the standard control of materials and in the study of product defectiveness.
