Polyester POY Paper Tube

For manufacturers specializing in polyester POY (Pre-Oriented Yarn) production, the Polyester POY Paper Tube is a specialized core accessory engineered to master low-tension winding processes. Featuring a composite structure with a low-friction inner layer (friction coefficient ≤0.15) and high-strength outer layer, this tube eliminates fuzz caused by tension fluctuations-one of the most common quality issues in POY production. With an inner diameter range of 200-300mm and wall thickness of 4-6mm, the Polyester POY Paper Tube undergoes special softening treatment, enabling tight spool formation with a filament density of 0.52g/cm³-8% higher than standard paper tubes. Its excellent temperature resistance shines in 80-100℃ environments, with a thermal shrinkage rate of only 0.2%, perfectly adapting to the heat-setting process in POY production. A major chemical fiber factory in Jiangsu achieved remarkable results: after adopting the Polyester POY Paper Tube, the fuzz rate of polyester POY filaments dropped from 1.2% to 0.3%, the breakage rate in subsequent DTY texturing processes decreased by 40%, and annual raw material loss costs were reduced by approximately 650,000 yuan. Ideal for conventional polyester POY production, especially 200D-800D medium to coarse denier POY filaments, this tube seamlessly matches the low-tension winding systems of POY spinning machines. It enhances product consistency, cuts waste, and boosts downstream processing efficiency-making it the smart choice for manufacturers aiming to elevate quality and profitability in the competitive polyester yarn market.
