An internal laboratory plays an important role in quality control and assurance in Čateks. The laboratory controls all input raw materials before use in production. The input control of raw materials before use in production. The input of raw materials is an important stage of production, since early detection of defects in raw materials, reduces unsatisfactory quality.

During the development of a new product, it is necessary to examine and determine the quality of the item at each stage. Based on the analysis of the laboratory testing, decisions are made about what will be changed and how depending on which properties of the item are to be achieved.

Laboratory tests are also regularly carried out in all phases of regular production, which enables the control of the uniform quality of products, all allowing monitoring of the stability of the technological process.

The Čateks Laboratory has the role of monitoring all production centers in Čateks, as well as R&D department with its tests and analysis. The laboratory examines the input control of raw materials (yarn, knitwear, fabric, dyeing), then the interphase control, and the output control of finished products.
