Fully Drawn Yarn (FDY) is produced directly from the melting of polyester spinning chips. Its production process is similar to the production method of POY With the difference that by applying more tension during production, it reaches a perfect makeup. This yarn is also called FOY which means Fully Oriented Yarn.
According to the production conditions of POY yarns (see the article on POY yarns), due to its low arrangement and poor physical and mechanical properties, POY yarn is usually not used directly in the weaving and knitting industry. Because FDY has a complete makeup, it is used directly in the weaving and knitting industry.
FDY is usually produced in a semi-dull, glossy form with various cross-sections such as round and triangular, raw white or in various colors as self-dyed (Dope Dyed).
FDY yarn is used in weaving and knitting. The shiny type with its triangular cross-section is usually used in the production of curtain fabrics, sheets and spun FDY in embroidery and sewing. In general, FDY yarn is used in home furniture fabrics, clothing fabrics, jeans and towels.
Features of FDY yarn are:
High strength: FDY yarns are preferred due to their high strength in producing durable and strong products.
Smooth surface: The completely smooth and flat yarn structure makes FDY yarns have a smooth surface, which makes the fabrics have a better texture and shine.
High Gloss: FDY yarns have a naturally glossy surface and therefore provide bright and vivid colors in fabrics.
High dyeability: FDY yarns are very suitable for dyeing and provide lasting colors in dyed yarns.
High elasticity: FDY yarns have good elasticity, which provides comfort and flexibility in clothing.
