Material: Vegetable parchment paper (sulfuric acid-treated parchment); made from 100% virgin wood pulp processed via parchmentization (not of animal origin); specifically designed for the outer wrapping of chemical fiber and textile paper tubes.
This colored or white parchment paper is supplied in rolls and wrapped around the outer surface of paper tube cores. It serves as the specialized outer-layer paper for paper tubes used with POY, DTY, and FDY chemical fibers, continuous filaments, and elastic yarns during spinning and texturing processes.
Standard Technical Specifications
• Basis weight: 50–90 gsm (predominantly 60–70 gsm)
• Moisture content: 6–7.5%
• Width: Slit to customer specifications; master rolls 600–1550 mm
• Form: Jumbo rolls (rewinding into smaller rolls available)
• Color: Natural white or custom colors (Pantone)
Product Applications
• Outer wrapping for POY paper tubes, DTY texturing tubes, and spandex yarn tubes in chemical fiber plants
• Edge wrapping and flanging for paper tube ends to prevent fraying or snagging of yarn at the rim
• Surface layer for paper cores used with filament, polyester, nylon, and elastic yarns
• Specialized outer wrapping paper for yarn tubes used in textile and texturing plants
Processing Specifications
After the paper tube is formed, the outer layer is wrapped with parchment paper; the parchment paper at the tube ends can be folded inward to create a hem. This effectively prevents dusting, fuzzing, and snagging at the ends during storage, and ensures the strand does not break during high-speed unwinding.
