partially oriented yarn (POY) is produced by melting polyester granule chips.
In the melt spinning process, the polyester granule is melted at high temperature and then converted into filament. Finally, the filaments are put together and form the POY yarn.
POY yarns are produced with different filament cross-sections, including circular, triangular, multi-ply and square or flat. Each of the cross-sections creates a different feature in the yarn, which is important in different applications. For example, the shape of the cross section of the filament is effective on the properties of compressibility, polish and luster of the yarn and the final product.
The low arrangement of molecular chains in this yarn determines its physical and mechanical properties. Due to the low elongation and strength of POY yarn, it is not directly used in weaving and knitting industries.
POY yarns are used in the production of other filament yarns including DTY, FDY, ITY, ATY and lycra. Therefore, the melting conditions of POY yarn will be effective in the production process and the quality of other filament yarns and the final fabric.
Mr Yarn produces semi-dull and super bright yarns in different grades.
