Material Characteristics of Chenille Yarn
Chenille yarn is typically made from a blend of fibers such as acrylic, wool, nylon, and silk. It offers excellent breathability and a skin-friendly feel, but differences in the binding force between fibers can cause surface fuzz to detach during friction.
Analysis of the Causes of Pilling
Mechanical Friction: During daily wear or washing, the yarn repeatedly rubs against external objects, causing the fiber ends to break and tangle into balls.
Insufficient Fiber Strength: Low-quality yarns have a high content of short fibers, making them more prone to breakage under external force.
Process Defects: Excessively high knitting density or improper needle selection can exacerbate fiber damage.
Systematic Prevention Solutions
Tool Optimization: Use polished titanium alloy or ceramic knitting needles to reduce the coefficient of friction during knitting.
Process Control: Maintain a moderate needle pitch (5-6mm recommended) to avoid overstretching the yarn. Using denser knitting techniques such as double rib can enhance the structural stability of the fabric.
Scientific Maintenance
Keep water temperature below 30℃ and use a dedicated detergent with a pH of 7-8.
When using a front-loading washing machine, select a spin speed below 400 rpm.
Regular steam ironing (at least 20cm away from the fabric) can reshape the fiber arrangement.
Key Points for Quality Identification
When purchasing, prioritize yarns with a long fiber content exceeding 70%. Verify raw material quality through burning tests (high-quality acrylic fibers produce black smoke and molten droplets) and twist tests (≥80 twists per 10cm).
Through comprehensive control over the entire process from raw material selection and production to post-production maintenance, pilling issues in chenille yarn can be effectively controlled, enhancing the market competitiveness of end products.
