25T/D PET Bottle to PSF Production Line
This is a solution recycle post-consumer bottles to synthetic fiber. All the fiber from waste PET bottles is recycled and eco-friendly.
Normally, BoReTech provides the fiber production line design which can make two or three types of fiber, such as good hollow conjugated fiber and regular tenacity solid fiber, or hollow conjugated fiber, regular hollow fiber and normal tenacity solid fiber.
We recommend customer to produce customized regenerated polyester staple fiber (PSF) with minimum power consumption and waste discharge. And we also coordinate with our customer to develop innovative downstream products with special fibers.
Post-consumed PET Bottles, RPET Flakes, RPET Chips, PET Lumps, PET Strap, Fiber Waste, Off-grade Chips
Specification and Capacity of Various Polyester Staple Fiber
One-stage service from PET bottle to Polyester staple fiber (PSF) ensures the final quality.
With the highest optimization of proposal to reduce the cost of project and achieve the maximum benefits.
Fully integrate the market resource, production technology and engineering experience into practical production system, and implement the technology transfer. Various Products would conform to the requirement of the customers and increase the competitive of the product in the market.
Steel platform design of spinning building reduces the height and cost of construction.
Automatic design of flakes feeding and drying system saves manpower and conversion cost as well as increasing the drying efficiency and flake quality.

*Configuration are optimized due to different types of fiber and capacity
Drum Drying: drying input recycled PET flakes and remove dust. After vacuuming, PET flakes water content will reach the required index;
Melting, extrusion, metering: PET flakes are fed into screw extruder, and moves forward by screw rotation. They are experienced a series of complex changes such as temperature, pressure, viscosity, etc. during moving.
Filtration: Filter impurities of PET flakes to prolong the service life of the components.
Spinning: Spinning is the most core section of polyester staple fiber production. rPET material are melted and extruded, under the action of pressure and heating, which are sprayed out through spinning holes, then cooled to form primary fibers.
Spinning Beam & Spinning Pack: it is mainly composed of metering pump and spinning pack, PET melt is fed into spinning pack through metering pump.
The spin pack has the function of filtering and pressurizing, removing impurities in the melt and evenly conveying the melt to the spinneret.
Quenching: The quenching device is the most important device in the spinning and cooling process. It can cool the yarn flowing out of each spinning hole uniformly, and reduce the sway and bonding to ensure a good spinning condition.
Take up: Take up bringing the tow together, drawing and fed into tow cans by sunflower feeding machine.
Creel: According to the process requirements, the polyester primary fibers are drawn out of the yarn head, and passed through tow guide, it is assembled into a bunch of fiber, which are be drawing later.
Crimper: Crimper can improve fiber friction coefficient, elasticity, feel, and thermal performance.
Oiling (anti-static) System: Add antistatic fluid to the oil tank to
