“…Glazing is a phenomenon where (usually after 8-10 years of use) the surface of the ceramic friction disk becomes smooth like glass, which leads to a less effective surface roughness and less friction that can be applied to the yarn. This is due to deposits of polymer and spin finish debris that accumulate in the pores of the ceramic [1,49]. They see the solution as either restoring the discs by plasma coating or disposing of the old and producing new ones.…”

The annual demand for fibres continues to rise worldwide. Consequently, more and more fibres must be produced to meet this demand, most of which are melt-spun polymeric man-made fibres. Smooth filaments made of polymers are mainly used for technical applications in industry. For use in clothing or home textiles, for example, a texturing process is used to give the filaments a crimp and thus a feel like that of natural fibres. In this state, they can be processed together with natural fibres and used in textiles. Partially oriented yarns (POY) are of great importance in texturing. The yarns are mainly crimped with the help of the so-called false-twist texturing process (FTTP). Since POY accounts for about 60% of the melt-spun filament yarn produced worldwide, the FTTP is the most important texturing process in the textile industry. In this paper, the main components of false-twist texturing (FTT) machines are explained, along with the state of the art and research for each component and its influence on the process. Relevant patents are discussed, as well as process optimisation techniques, innovative polymers, and yarn types recently used in FTT, followed by a conclusion and an outlook for the process.

“…The researchers achieve this porosity by using a high-speed sprayer. This gives the disc a surface roughness R a of less than 3 µm, which is improved to 0.63 ≤ R a ≤ 1.25 µm through further mechanical post-processing [49].…”

“…This is due to deposits of polymer and spin finish debris that accumulate in the pores of the ceramic. [4,49] They see the solution as either restoring the discs by plasma coating or disposing of the old and producing new ones. The biggest problem with restoration is applying a new surface without changing the actual shape of the pane.…”

The annual demand for fibres continues to rise worldwide. Consequently, more and more fibres must be produced to meet this demand, most of which are melt-spun polymeric man-made fibres. [1] Smooth filaments made of polymers are mainly used for technical applications in industry. For use in clothing or home textiles, for example, a texturing process is used to give the filaments a crimp and thus a feel like that of natural fibres. In this state, they can be processed together with natural fibres and used in textiles. Partially oriented yarns (POY) are of great importance in tex-turing. The yarns are mainly crimped with the help of the so-called false-twist texturing process (FTTP). [2] Since POY accounts for about 60 % of the melt-spun filament yarn produced world-wide, the FTTP is the most important texturing process in the textile industry [3]. In this paper, the main components of false-twist texturing (FTT) machines are explained along with the state of the art and research for each component and its influence on the process. Relevant patents are dis-cussed as well as process optimisation techniques, innovative polymers and yarn types recently used in FTT, followed by a conclusion and an outlook for the process.
