Partially Oriented Yarn (POY):
POY (Partially oriented yarn) is largely used in shirtings and suitings, sarees, ladies’ dress material, and knitwear. POY is preferred in men’s wear due to its higher crease recovery, wrinkle resistance, better drape, longer retention of prints and colors, and better abrasion as compared with competing fibers, such as PSF, VSF, and NFY. The use of POY in sarees has increased due to the development of crimping, twisting, texturizing, and wet processing technologies. POY is a substitute for cotton and other synthetic yarns.

Partially oriented yarn is produced from the melting and extrusion (melt spinning) of the polyester chip or flake. During the spinning process, the filaments are stretched or drawn as much as five times their original size to orient the polymer to meet the desired evenness, strength, shrinkage, and elongation properties. So the term POY refers to a multi-filament that is only partially stretched. POY is generally lower in tenacity and less uniform than fully oriented yarn (FOY). POY is mainly used in texturizing to make textured yarn and can also be used in draw warping for weaving and warp knitting of fabrics.
Semi-Dull is a white and slightly opaque polyester type with 0.35 wt% of titanium dioxide (TiO2) content. Whereas, POY is a type of yarn produced from polyester fibers derived from continuous filament using molten spinning. The used filament fibers have low strength with a very high percentage of elongation. This study aims to analyze the elongation properties of the yarn produced during the molten spinning process of raw materials.
