Classification and appearance of FDY YARN

FDY yarn stands for Fully Drawn Yarn. It is a type of polyester filament yarn that is produced by a continuous filament spinning process. During the spinning process, the polyester chips are melted and extruded through spinnerets to form filaments. These filaments are then stretched or drawn to orient the polymer chains in a particular direction, which increases the strength and tenacity of the yarn.FDY yarn has a smooth and lustrous appearance and is available in a wide range of deniers, from fine to coarse. It is commonly used in textile applications such as weaving, knitting, and embroidery. FDY yarn is also used in the production of fabrics, home furnishings, and carpets.

FDY is commonly used in the textile industry for a variety of applications such as apparel, home textiles, and industrial textiles.FDY yarns can be classified based on several parameters such as:Denier: FDY yarns are available in a range of deniers, which refers to the thickness of the yarn. Common deniers for FDY yarns are 50D, 75D, 100D, 150D, 300D, and 600D.Luster: FDY yarns can be categorized based on their luster or shine. They are available in two main types: semi-dull and bright. Semi-dull yarns have a matte finish, while bright yarns have a glossy finish.Cross-section: FDY yarns can have different cross-sectional shapes, which can affect their properties and performance. Some common cross-sections for FDY yarns include round, trilobal, and hollow.Twist: FDY yarns can be twisted or untwisted. Twisted yarns have better abrasion resistance and strength, while untwisted yarns are smoother and have a better drape.Color: FDY yarns are available in a wide range of colors, including solid colors, heather colors, and multi-colored yarns.Stretch: FDY yarns can also be classified based on their stretch or elasticity. Some FDY yarns have low stretch, while others have high stretch, making them suitable for different applications.

Overall, the classification of FDY yarns depends on various factors, and the selection of a particular type of FDY yarn depends on the specific application requirements.
