摘要
适应色纺纱线个性化、高档化的市场需求,开发一种基于数控耦合牵伸理论的色纺技术。其技术关键在于两组合后罗拉由两个伺服电机驱动,与中罗拉形成相互独自的两个后牵伸区。通过调节伺服电机速度控制两根粗纱随机且相互耦合的牵伸比,在前罗拉钳口处形成具有等线密度的色纺段彩纱。分析了双组份耦合牵伸的基本原理,推导了其配色花型分布控制的基本方程,用实验验证了等线密度段彩纱随机性花型的可设计性与再现性。
To adapt to the market requirement of personalized and high-end colored spun yarn, this research develops a colored spinning technology based on NC coupling drafting theory. The key of this technology is that two combined back rollers are driven by two servo motors and form two independent drafting zone with middle roller. Segment color yarns with equal linear density are formed at the jaw of front roller by adjusting the speed of servo motor to control the random and coupled draft ratio of two thick yarns. This paper analyzes the basic principle of bi-component coupling drafting, infers the basic equation of distributed control of color pattern and verifies the designability and reproducibility of random color pattern of segment color yarn with equal linear density with an experiment.
