In the wave of continuous upgrading of the textile industry, Polyester Yarn is reshaping the cost and efficiency pattern of the global textile industry chain with its advantages in large-scale production and technological iteration capabilities. From raw materials to finished product processing, this synthetic fiber provides the industry with both economical and sustainable solutions through full-chain optimization.
Controllable raw material costs: the core advantage of large-scale production of PTA
PTA (purified terephthalic acid), the core raw material of polyester fiber, accounts for more than 60% of its production costs. As the global leader in PTA production capacity (accounting for 92% of the world), China has achieved increased self-sufficiency and price stability of raw materials through integrated refining and chemical layout and process optimization. For example, in 2024, the price of PTA remained in the range of 5,700 to 6,050 yuan/ton, and the cost dilution effect brought by large-scale production was significant. Compared with textile companies that rely on natural fibers, polyester yarn users can avoid price risks caused by climate or supply chain fluctuations in raw materials such as cotton and wool, and achieve precise budget control.
Production efficiency leap: full process optimization from spinning to finished products
The industrialized characteristics of polyester fiber make it suitable for high-speed automated production. Taking vortex spinning technology as an example, when Wujiang Jingyi Company uses this technology to produce marine recycled polyester yarn, the daily output of a single machine reaches 1,200 kg, and the production efficiency is as high as 97%. The new winding device developed by Jiaxing Deyi Company reduces fiber loss by 15% and increases winding speed by 30% through air expansion shaft tension adjustment and pre-tightening component design 8. Such technological innovations shorten the process time of polyester yarn from spinning to weaving by 20%-40%, significantly reducing unit energy consumption and labor costs.
Functional expansion: Reduce investment in downstream processing links
The modifiable characteristics of polyester fiber further reduce downstream processing costs. By adding antibacterial, anti-UV masterbatch or special-shaped cross-section design, the yarn has the functions required for the end product in the spinning stage, reducing the chemical reagents and energy consumption in the subsequent printing and dyeing and finishing links. For example, the dyeing efficiency of functional polyester fabrics is 40% higher than that of natural fibers, and the color fastness is improved by more than 2 levels, which greatly reduces the rework rate and wastewater treatment costs.
Green transformation: the hidden competitiveness of long-term cost efficiency
Under the trend of low-carbon transformation in the global textile industry, polyester fibers show long-term cost advantages through the circular economy model. Marine recycled polyester yarn uses recycled plastic bottles as raw materials, and the production cost is 12%-18% lower than that of virgin fibers. At the same time, it meets the requirements of regulations such as EU carbon tariffs and avoids additional expenses caused by potential trade barriers. In addition, the durability of polyester yarn (such as wrinkle resistance and wear resistance) can extend the life cycle of textiles, reduce customer repurchase frequency and resource waste.
