Loptex is the first company in the market that introduced the concept of sorting out contaminants from a free fibers stream through pneumatic valves with minimum loss of lint. The application refers to preparation lines at the beginning of the process before carding machines. This concept led to the design of a unique system to be integrated in existing and in new blow room lines of any brand. Loptex, through in-house embedded technologies, faces the critical environment conditions of the opening process. The modular design, the high resolution and accuracy of the color camera system and the use of multiple light sources, enhance the comprehensive detection and the elimination of all type of contamination. The unique Loptex know-how optimizes the combination of multiple embedded technologies. Harmful contamination visible on fabrics follows spinnability and non-dyeability criteria. Loptex, as leading company on contamination control in cotton Spinning Mills, is present in all the major textile areas in the world assuring sale and after sales support to its customers.
