Polyester is a synthetic fiber made from the reaction of ethylene glycol with dimethyl terephthalate in high heat. It is melted into strips, which are spun through the spinneret to create fibers. These fibers are then twisted together to form yarns that can be used for many different types of textile fabrics and products. The demand for polyester is growing worldwide, particularly in Asia, where the construction industry is booming. The use of polyester in these applications saves cement and fly ash, which makes it an attractive option for manufacturers.
The market for polyester poy is expected to grow at a CAGR of 7.7% shortly. The key drivers of this growth are the rapidly increasing construction, textiles, and automotive industries in Asia-Pacific, especially China and India. Furthermore, the availability of cheap labor in Asia and increasing consumer spending are also contributing to the growth of this market.
Partially Oriented Yarn (POY) is the first form of polyester yarn produced directly from PTA MEG or by spinning Polyester PET Chips. When a high-speed spinning process is applied to this yarn, it can be elongated up to five times its original length. The result is a yarn with high orientation and moderate crystallinity. This type of yarn is known as polyester pre-oriented yarn.
This yarn is then spooled and wound into large bobbins for subsequent processing. During this stage, the polyester filaments are mechanically stretched and treated with heat to partially align in parallel formation, allowing them to be twisted or drawn into a variety of textures and shapes. For example, a polyester filament may be twisted or drawn into a filament that is softer or duller than the original POY. This is referred to as drawing false twisted textured yarn, or DTY. The DTY is then spun into fabric.
DTY is a versatile yarn that can be used for a wide range of textile applications, including weaving and knitting. It is used to produce fabrics for clothing, such as suits and shirts, as well as home furnishings, such as bed sheets and draperies. It can also be used for making car interiors and upholstery, as well as industrial and medical textiles.
The new aesthetics of techno fashion helped to popularize the use of polyester, a substance that had been used in industrial textiles for over a century by the time it reached the fashion industry. Its high-strength, water-resistant, and crease-repellent qualities have since been used in a variety of contemporary designs. The polyester fiber is also being increasingly used to create new fabrics for outdoor sportswear and apparel. Its durability and comfort are matched only by its versatility.
