Absorption Cotton

1. Product Definition and Material Specifications The cotton pads specified by clients are oil-absorbing cotton pads, primarily manufactured from needle-punched cotton. This material is formed by cutting cotton sheets into shape through a needle-punching process, with a standard thickness range of 2–5mm. Currently, due to equipment stroke limitations, the minimum thickness we can achieve for one-piece cotton (polymer cotton) is 3mm per cut. 2. Structural Design and Processing Advantages - Right-Angle Precision: Many client requirements for cotton pad structures necessitate right-angle edges. Needle-punched cotton cutting can achieve perfectly sharp right angles, ensuring precise geometry. - Molding Limitations: In contrast, one-piece polymer cotton is produced via mold forming, which inherently cannot create absolute right angles. Instead, its edges feature a certain R-angle curvature due to the molding process. 3. Technical Features - High-Density Fiber for Rapid Absorption With a 3D braided structure boasting a fiber density of 12,000 fibers/cm², this material absorbs oil 50% faster than standard products. Its saturation capacity reaches an impressive 8ml per gram, ensuring efficient liquid retention. - Gradient Porosity for Even Distribution The gradient porosity design enables uniform liquid distribution, preventing concentration hotspots and optimizing absorption efficiency. - Extreme Temperature Resistance and Longevity Capable of withstanding temperatures from -20°C to 200°C, the product lifespan is extended to 6,000 hours—four times longer than the standard 1,500-hour service life. - Enhanced Performance Attributes - Efficient Absorption: Maximizes liquid capture with minimal saturation delay. - Leak-Proof & Clog-Free: Engineered to prevent leakage and resist particle accumulation, maintaining consistent performance. - Lightweight & Cost-Efficient: Balances low weight with economic viability, ideal for large-scale applications. This revised version emphasizes technical precision, structural advantages, and performance metrics while maintaining clarity and professional tone.
