Textile process controllers perform textile process operations, technical functions in various aspects of design, production and quality control of textile products, and cost control for processes. They use computer aided manufacturing (CAM), and computer integrated manufacturing (CIM) tools in order to ensure conformity of entire production process to specifications. They compare and exchange individual processes with other departments (e.g. cost calculation office) and initiate appropriate actions. They analyse the structure and properties of raw materials used in textiles and assist to prepare specifications for their production, analyse and interpret test data.
