The Manufacturing Process of Polyester DTY Yarn

Polyester DTY yarn is a multifilament synthetic yarn that offers strength, elasticity, and softness - three essential qualities when designing high-quality textile products such as apparel. Polyester DTY yarn's versatility has made it popular among manufacturers and designers who seek to produce long-wearing textiles at an economical cost. Furthermore, Polyester DTY yarn represents an economical alternative to many natural fibers while still offering similar performance at more reasonable costs.
DTY yarn manufacturing begins with the spinning of Partially Oriented Yarn (POY). This yarn is produced with colored and white polyester chips using modern machines that ensure consistent results of high-quality yarns. Once dyed in various shades using a sizing system that evenly disperses color throughout its entirety, then cooled down for proper cooling processes, it forms the core of DTY.
Once a POY yarn is ready to undergo further processing, it is subjected to texturization - a post-spinning operation that modifies its surface to add texture and bulkiness - usually on POY; FDY may also be texturized. When this occurs, draw texturized yarn (DTY) results from multi filar yarn that exhibits soft textures with gentle crimps while having substantial textural bulkiness.
Once texturized, the yarn is then twisted for further processing. Twisting techniques depend on specific applications and machines and may vary according to needs - non-intermingled (NIM), low or softly intermingled (LIM/SIM), or high intermingled (HIM). Intermingled DTY yarns combine light and heavy twisted yarns which are intermingled using an intermingling nozzle, then permanently thermo-set with its twist set permanently into place.
DTY fabric's versatility enables it to be woven into an array of fabrics. Most often found in apparel applications due to its softness and comfort properties, DTY can serve as an ideal substitute for natural fibers like wool or cotton. Being quick-drying helps wick sweat away faster than other fabrics while being lightweight makes DTY ideal for activewear and outerwear applications as well as home textiles (bedsheets/curtains) and automotive textiles (seat covers/headliners) applications as well as fashion accessories like scarves/ties etc.
