As global sustainability efforts intensify, an increasing number of textile manufacturers are turning to recycled PET materials to address the challenges of resource scarcity, environmental responsibility, and rising production costs. Boretech was among the early pioneers in this field, launching a mature Bottle-to-Polyester Staple Fiber (B2F) solution years ago.
This solution encompasses the entire process—from PET bottle recycling, material blending, and melt spinning to final fiber baling —and has already been implemented widely across the globe. It has become a key enabler for developing local recycled fiber production capacity.
Building on this well-established platform, Boretech recently introduced its latest innovation—the ECOSPIN polyester staple fiber production system. This next-generation system significantly enhances the performance of the B2F solution in terms of operational efficiency, fiber quality, and return on investment, offering customers a more competitive and sustainable solution.
Boretech’s B2F Solution: A Proven Platform for Recycled Polyester Staple Fiber Production
The Boretech B2F solution stands out for its flexible configuration, high efficiency, and intelligent control. Designed to meet the needs of various regions and portfolios, the solution offers customized capacity options ranging from 15 to 100 tons per day, and supports a wide variety of fiber specifications—including cotton-type, nonwoven, hollow conjugate fiber, hollow fiber, and dope-dyed fibers (ranging from 1.2D to 25D).
Covering the full production process—from PET bottle processing and additive dosing to mixing and final fiber output—the B2F solution ensures process continuity and product consistency. Its integrated intelligent control system enables quality traceability, remote diagnostics, and process optimization, minimizing operator interference while improving operational efficiency.
ECOSPIN: Next-Generation Spinning System that Empowers B2F
ECOSPIN, Boretech’s newly developed spinning platform, is designed to improve fiber production efficiency while significantly reducing energy consumption and construction cost. Seamlessly integrating with the B2F line, ECOSPIN helps customers achieve more sustainable and economical fiber production.
Key Advantages:
- Lower Energy Consumption: The system enables large throughput, low heating power, and excellent devolatilization and impurity removal. Compared to conventional drying systems, ECOSPIN reduces energy consumption by 30–50%.
- Low Investment Cost: The dynamic drying system minimizes requirements for building area and load-bearing structures, reducing construction cost to just 45% of that required for conventional spinning setups.
- Superior Melt Quality: With a residence time of just 28 seconds, significantly shorter than standard systems, which mitigrates the melt deterioration. Simultaneously, it delivers excellent moisture and VOC removal performance.
- Wide Product Compatibility: Suitable for various fiber types, including cotton-type, hollow conjugate fiber, and high-tenacity, ECOSPIN is highly versatile.
- Automation Control: The system features intelligent process control that automatically matches spinning positions, feeding rates, and system parameters to ensure stable and optimized operation.
The ECOSPIN system is available in 30–100 TPD capacity configurations, making it an ideal solution for medium and large-scale recycled fiber projects, especially those targeting a balance between energy efficiency, cost control, and product quality.
Empowering the Region’s Green Transition
With its proven B2F solution and cutting-edge ECOSPIN spinning technology, Boretech is delivering real, scalable green manufacturing capabilities to textile customers . From raw material supply and equipment integration to after-sales support, Boretech provides a one-stop engineering solution that enables local enterprises to build sustainable production capacity and expand recycled fiber applications in various products.
