• Global Supply Capability: Sinrylion’s products are exported to over 100 countries and regions worldwide.

• Timely Delivery: Our global distribution network ensures that every customer’s needs are met promptly.

Recycled Polyester Yarn Production Process

Sinrylion's recycled polyester yarn production process has been optimized over many years, ensuring the stability and high performance of each batch of products.

Raw Material Sourcing and Cleaning

The first step in the recycled polyester yarn production process is sourcing high-quality recycled polyester materials. These materials are primarily derived from post-consumer and post-industrial waste, such as used plastic bottles, polyester fabric scraps, and other recyclable polyester products.

• Sourcing: We partner with certified global suppliers who provide high-quality, clean, and recyclable polyester waste.

• Cleaning: Before the raw material can be used in production, it must undergo a multi-step cleaning process to remove impurities such as dirt, oils, dyes, and adhesives. This is done through 4 cleaning cycles to ensure that the polyester is thoroughly purified and ready for processing.

Melt Spinning

The next step is the core process of producing recycled polyester fibers, known as melt spinning. During this process, the polyester pellets are melted at a high temperature and then extruded through a spinneret (a device with many tiny holes) to form continuous filaments of fiber.

• Melting: The polyester pellets are heated to their melting point in an extruder, where they are turned into a liquid state.

• Extrusion: The liquid polyester is forced through the spinneret to form fibers. These fibers are then rapidly cooled as they pass through air chambers, solidifying into long continuous strands of polyester filament.

Drawing and Stretching

Once the polyester fibers are extruded, they are still in a relatively soft state and must be drawn out to increase their strength, elasticity, and durability. This step is called drawing or stretching.

• Drawing Process: The fibers are stretched by passing them through rollers moving at different speeds. This process aligns the molecules within the fiber, enhancing its tensile strength and making it suitable for further textile applications.

• Stretching Ratio: Sinrylion ensures that the stretching process is carefully controlled to avoid over-stretching, which could lead to poor yarn quality. The stretching ratio is optimized to balance strength and flexibility.

Quality Inspection and Testing

Before the yarn is ready for sale or further use, it undergoes a series of rigorous quality checks to ensure that it meets the required specifications.

• Physical Properties Testing: Sinrylion tests the yarn for essential properties, such as tensile strength, abrasion resistance, and elasticity.

• Diameter and Uniformity Checks: The diameter of each yarn is checked to ensure uniformity. Variations in diameter can affect the quality of the finished fabric.

• Color Matching: For applications requiring specific colors, the yarn is dyed and tested for color consistency and fastness.
