Polyester mother yarn and nylon mother yarn are the two most widely used raw materials for mono filament tex mono split production, and their physical properties lead to completely different splitting process parameters and operation standards. Clarifying the differences can effectively reduce defective products and raw material waste in mother yarn splitting machine production.
In terms of tensile property, polyester mother yarn has 28% higher breaking tenacity than nylon mother yarn. It can adapt to high-speed splitting of 280–320 m/min, while nylon mother yarn is only suitable for 200–260 m/min operating speed to avoid fracture. Excessive speed is the main cause of nylon mono filament breakage.
Temperature adaptability varies significantly between the two materials. Polyester mother yarn can maintain stable performance at 18–32℃, while nylon mother yarn is sensitive to low temperature. Environment temperature below 22℃ will increase nylon brittleness by 33%, greatly improving splitting failure rate.
Tension control standards are totally different. Polyester mother yarn bears feeding tension of 0.18–0.28 cN/dtex, while nylon mother yarn needs lower tension of 0.12–0.22 cN/dtex. Excessive tension will cause nylon fiber micro-cracks, affecting the durability of finished mono filament.
Static sensitivity is another key difference. Nylon mother yarn generates 40% more static electricity during splitting than polyester mother yarn. Without static elimination equipment, nylon mono filament adhesion rate will reach 8.7%, seriously affecting tex mono split product uniformity.
Wear resistance of raw materials affects cutter loss. Polyester mother yarn has higher surface hardness, causing 18% faster cutter wear than nylon materials. Factories need to appropriately increase cutter inspection frequency when long-term processing polyester mother yarn.
Moisture absorption performance leads to different storage requirements. Nylon mother yarn has stronger moisture absorption, with optimal storage humidity of 50–65%. Polyester mother yarn is less sensitive to humidity, adapting to 45–70% relative humidity environment for storage and production.
Lanxiang mother yarn splitting machine is designed with dual-mode parameter system, independently optimizing process settings for polyester mother yarn and nylon mother yarn. The dual-setting design avoids parameter confusion and ensures stable tex mono split quality for different raw materials.
Finished product application scenarios are differentiated. Polyester mono filament is mostly used for industrial mesh and thick decorative fabrics, while nylon mono filament is widely applied in soft textile and high-flexibility weaving products due to better toughness.

Q2: Why is nylon mother yarn more prone to static adhesion during splitting? A2: Nylon generates 40% more static electricity than polyester, increasing mono filament adhesion rate. Q3: What is the optimal feeding tension range for nylon mother yarn splitting? A3: Nylon mother yarn feeding tension is controlled at 0.12–0.22 cN/dtex for stable splitting. Q4: What temperature will significantly increase nylon mother yarn brittleness? A4: Environment temperature below 22℃ will greatly improve the brittleness and fracture risk of nylon yarn. Q5: Which raw material causes faster cutter wear during tex mono split processing? A5: Polyester mother yarn has higher hardness and accelerates cutter wear by 18% than nylon yarn.
