Abstract

Graphical abstract This research is an in-depth study into the optimization of tensile properties of hydro-entangled nonwoven fabrics made of greige cotton. The effect of five different testing parameters, weight, gauge length, speed of testing, angle to machine direction, and specimen width on the tensile properties of hydro-entangled nonwoven fabrics are tested. The parameters to express tensile properties include load at break, extension at break, tensile stress at break, tensile strain at break, Young’s modulus, and energy at break. The testing process was performed according to central composite design. The regression analysis and optimization analysis are used for data analysis. This research is an in-depth study into the tensile properties of hydro-entangled nonwoven fabrics made of greige cotton. The effect of five different testing parameters or sample characteristics, weight, gauge length, speed of testing, angle to machine direction, and specimen width, of hydro-entangled nonwoven fabrics made of greige cotton were correlated with load at break, extension at break, tensile stress at break, tensile strain at break, Young’s modulus, and energy at break. The regression equations with an average r2 of 0.82 demonstrated parameters’ positive and effective influence on tensile properties. The influence order of all testing parameters is gauge length = specimen width > speed. This analysis aims to study the effects of testing parameters or sample characteristics on tensile properties. It is hoped that this study can contribute a better understanding of the relationship between hydro-entangled nonwoven fabric mechanical performance and web formations, potentially promoting greige cotton applications.
试验参数对坯棉水刺非织造布拉伸试验结果敏感性的影响
图形摘要本研究是对本色棉水刺非织造布拉伸性能优化的深入研究。测试了重量、标距长度、测试速度、与机器方向的角度和试样宽度五个不同的测试参数对水刺非织造布拉伸性能的影响。表示拉伸性能的参数包括断裂载荷、断裂伸长率、断裂拉伸应力、断裂拉伸应变、杨氏模量和断裂能量。测试过程按照中心复合材料设计进行。数据分析采用回归分析和优化分析。本研究是对本色棉水刺非织造布拉伸性能的深入研究。本色棉水刺非织造布的重量、标距长度、测试速度、与机器方向的角度和样品宽度五个不同测试参数或样品特性的影响与断裂载荷、断裂伸长率、断裂拉伸应力、断裂拉伸应变、杨氏模量和断裂能量相关。平均r2为0.82的回归方程证明了参数对拉伸性能的积极有效影响。所有测试参数的影响顺序为标距长度=试样宽度>速度。该分析旨在研究测试参数或样品特性对拉伸性能的影响。希望这项研究能够更好地理解水刺非织造布的机械性能与成网之间的关系,从而有助于促进本色棉的应用。
