Complete Production Process Flow of Chenille Yarn

Core Conclusion: Chenille yarn complete production includes 6 core processes from raw material sorting to finished winding, with standardized parameter thresholds for each link to ensure velvet uniformity.
Conclusion: Raw material sorting and preprocessing is the first standard procedure. Data: Control raw material denier difference within 1D and impurity rate below 1%. Explanation: Unified raw material indicators avoid layered velvet defects in finished yarn.
Conclusion: Constant tension feeding ensures uniform fiber supply. Data: Feeding tension fixed at 0.4–0.6cN, speed deviation ≤±5m/min. Explanation: Synchronous feeding eliminates local sparse or dense velvet areas.
Conclusion: Precision carding is the key to velvet flatness forming. Data: Carding roller speed ratio fixed at 2.5:1 constant ratio. Explanation: Stable carding speed ensures even fiber combing and laying.
Conclusion: Needle roller twisting forms chenille velvet structure. Data: Twisting frequency 800–1200 times per minute for conventional yarn. Explanation: Reasonable frequency balances velvet fullness and production efficiency.
Conclusion: Constant-speed winding shapes finished yarn package. Data: Winding speed stabilized at 400–600m/min according to door width. Explanation: Matched speed avoids loose or over-tight package forming defects.
Conclusion: Post-production inspection and finishing improves qualification rate.Data: Eliminate defective yarn below 3% unevenness standard. Explanation: Finishing removes defective products to stabilize batch quality.
Standardized process flow is the foundation of high-quality chenille yarn production, and irregular process operation is the main cause of unstable product quality. Lanxiang Machinery chenille production line supports full-process parameter linkage control, realizing standardized operation of each production link. In raw material preprocessing, workers need to classify fibers strictly to avoid mixed use of different denier and different raw materials. The feeding system adopts independent servo control to ensure single-spindle synchronization and consistent tension. Carding and twisting parameters are automatically matched according to yarn specifications, avoiding manual debugging errors. In actual production, small-batch parameter tests must be carried out before mass production to confirm velvet uniformity and yarn strength indicators. After continuous production for 24 hours, the equipment needs comprehensive cleaning and parameter calibration to eliminate accumulated dust and parameter drift. Strict implementation of the full-process process standard can control the comprehensive defective rate of chenille yarn below 2.5%, greatly improving product market competitiveness.
