Nylon FDY Paper Tube

Our Nylon FDY Paper Tube is a special paper tube built for nylon fully drawn yarn production, with all-round optimization for the characteristics of nylon yarn such as fine texture, high elasticity and easy snagging. Nylon FDY has high spinning speed and fine tow, which requires much higher inner wall smoothness and concentricity of paper tubes than ordinary chemical fiber paper tubes. We have carried out ultra-precision polishing treatment on the inner wall of this Nylon FDY Paper Tube, with no burrs, no protrusions and no fiber precipitation on the surface, which can completely eliminate snagging and yarn breakage during high-speed winding, and ensure the surface quality and yield of nylon yarn.

In terms of structural precision, Nylon FDY Paper Tube implements strict tolerance standards in the industry. The inner diameter tolerance is controlled within ±0.05mm, and the radial runout is ≤0.06mm. It has excellent dynamic balance performance during high-speed rotation, which can effectively reduce equipment vibration and extend the service life of spinning machine bearings. The tube body is made of high-strength long-fiber paper through multi-layer winding, matched with a fatigue-resistant material formula, which can withstand the repeated stress of high-tension winding of nylon FDY and is not easy to lose roundness or deform during long-term use. As a National High-tech Enterprise with 16 years of R&D experience in chemical fiber paper tubes, each batch of our Nylon FDY Paper Tube is verified by actual nylon spinning machine tests to ensure that product performance matches customers' high-speed spinning production lines.

• Nylon spinning production: suitable for winding stations of high-speed nylon FDY spinning machines

• Nylon yarn post-processing: used for intermediate winding with texturing, covering and other processes

• High-end chemical fiber export: standardized export packaging of finished nylon filament

We have been deeply engaged in the chemical fiber paper tube field for 16 years. Our production base covers an area of 15,000 square meters, with a dedicated nylon paper tube production workshop and on-machine test laboratory, equipped with multiple high-precision automatic tube winding production lines. There are nearly 20 people in the technical R&D team focusing on process development of fine denier chemical fiber paper tubes. As a National High-tech Enterprise, we hold multiple structure and process invention patents related to nylon paper tubes, and have in-depth mastery of the full-process process pain points of nylon spinning. At present, we have established long-term cooperation with many leading domestic nylon chemical fiber enterprises, and our products are exported to Southeast Asian nylon textile industry clusters, making us one of the professional suppliers of nylon FDY paper tubes in China.

For the high-precision requirements of Nylon FDY Paper Tube, we have established an exclusive quality inspection process. The base paper is selected from high-purity long-fiber wood pulp paper to reduce the risk of fiber falling off from the source. During winding, we monitor inner wall smoothness and dimensional accuracy throughout the process, and sample for roundness and runout testing every hour. At the finished product stage, inner wall highlight inspection and friction test are added to ensure no burrs, no protrusions and smooth tow sliding. All finished products undergo 100% full inspection before packaging, and any products with subtle defects are rejected. Meanwhile, on-site inspection by third-party authoritative institutions is supported. Each batch of products can be issued with a complete test report, and the quality is fully traceable.

We have passed ISO9001:2015 Quality Management System Certification. The production process and performance indicators of Nylon FDY Paper Tube comply with international chemical fiber industry consumable standards. All raw materials used in the product meet EU ROHS environmental protection requirements, no harmful substances are precipitated, and will not affect the subsequent dyeing and setting processes of nylon yarn. We are a National High-tech Enterprise and a Zhejiang Science and Technology Enterprise, hold multiple invention patents for chemical fiber paper tubes, and our product quality has been recognized by many world-renowned chemical fiber brands. Complete qualification documents and material test reports can be provided to meet customers' compliant procurement needs.
