摘要：

为更好地了解涤/棉混纺机织物起毛起球过程,基于对织物起球过程表面毛羽测量得到的毛羽分布特征,借助PYTHON语言建立了织物及其表面毛羽的几何模型,同时利用有限元软件ABAQUS研究了涤/棉混纺机织物表面毛羽的起球过程,分析了涤纶弹性模量对涤/棉混纺机织物起球过程的起球等级、能量吸收形式的影响规律,并将有限元仿真的起球结果和实测起球结果进行对比分析。结果表明:涤纶弹性模量的增加使得涤/棉混纺机织物的起毛起球等级降低;摩擦耗散能是涤/棉混纺机织物起毛起球过程的主要能量吸收形式,织物起毛起球等级的仿真结果与实验结果的差异在7.4%以内,证明有限元仿真的可行性。

Abstract:

In order to better understand pilling of polyester/cotton woven fabrics, a geometric model of the fabric showing hairiness was established by using PYTHON language with ABAQUS, on the basis of the measured the distribution characteristics of hairiness during pilling. The finite element simulation model for fabric pilling were validated using experimental data, and the differences in pilling grades between the simulated and the experimental results is about 7.4%, which proves the feasibility of finite element simulation. The effects of elastic modulus of polyester fibers on pilling grades and energy absorption form of pilling were analysed. The results indicate that when the elastic modulus of polyester fibers is increased, the pilling grade of polyester/cotton woven fabric is reduced. Friction dissipation energy is the main form of energy absorption during pilling of polyester/cotton woven fabrics.

Key words: polyester/cotton woven fabric, balling and pilling, finite element simulation, fiber elastic modulus, friction dissipation energy
