Optimization of Fiber Laydown During the Fiber Spinning Process by Utilizing the Coanda‐Effect
Abstract: The laydown of aerodynamically stretched fibers during fiber spinning is a key feature of the non‐woven quality. The desired properties of the produced non‐woven are mostly determined by the mechanical properties of the single fiber and the homogeneity of the spunbond. While the former is studied widely, the homogeneity is mostly studied by simulations and not experimentally. Cloudiness or formation of non‐wovens is a known phenomenon that describes deviations from the ideal laydown. Thin areas have a huge impact on the mechanical properties of the spunbond; And subsequently, the investigation of the fiber laydown is of great interest. This work presents an experimental approach to optimize the fiber laydown of a pilot plant fiber spinning device consisting of two aerodynamic stretching devices (aspirators) that stretch eight single fibers each. Due to fiber accumulation on the lay‐down belt under each of the aspirators, a metal rod is placed in‐between to deflect the fibers into the center utilizing the Coanda‐effect to achieve a broad homogeneous fiber distribution.
