PET Bottle to Dope-dyed Fiber 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.

Input material:
Post-consumed PET Bottles, RPET Flakes, RPET Chips, PET Lumps, PET Strap, Fiber Waste, Off-grade Chips

PET Bottle to Dope-Dyed Fiber Line

PET Bottle to Dope-Dyed Fiber Line
Process Intro
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 remove static electricity.
Drawing: Through drawing, the fibers have the fineness, strength and elongation required for textile processing.
Folding Machine: transform the original left and right chemical fibers into upper and lower distribution and reintegrate.
Relaxer: remove the fiber moisture, so that the fiber meets the required moisture content of the finished product, at the same time to avoid fiber becoming yellow as oil with moisture.
Baler: make PET fiber baled into baler.
