【摘要】 为解决服装领域3D打印涂层图案易于剥离的问题，探究几何拓扑结构对涂层与织物界面黏合强度的影响。基于几何拓扑设计理念，构建圆柱、圆锥、圆台、圆顶柱4类特征单元三维模型，结合光固化立体成型(Stereolithography Apparatus,SLA)技术，采用分层实验设计方法在同一材质混纺基材上制备系列试样，依据GB/T2790—1995《胶粘剂180°剥离强度试验方法 挠性材料对刚性材料》检测界面黏合性能。结果表明:圆柱拓扑结构因无直接着力点且垂直应力均匀分布，界面黏合强度达120.2 kN/m，较圆锥(109.1 kN/m)、圆台(80.8 kN/m)、圆顶柱(78.7 kN/m)分别提升10.2%、48.8%、52.8%;基于该结构打印的3D服装涂层图案，黏合强度显著优于ISO 13935《纺织品接缝强力性能测定第2部分》中功能性服装辅料的要求，可有效提升3D打印涂层与织物的结合牢度。更多还原

【Abstract】 To address the issue of easy peeling of 3D-printed coating patterns in the clothing field,and to explore the influence of geometric topological structures on the adhesion strength between the coating and the fabric interface,four types of feature units,namely cylinder,cone,frustum,and dometopped cylinder,were constructed in three-dimensional models based on the geometric topological design concept. Combined with the combined with light-curing printing technology,a layered experimental design method was used to prepare a series of samples on the same material blended substrate. According to GB/T 2790-1995 " Test Method for 180° Peel Strength of Adhesives-Flexible Materials against Rigid Materials",the interface adhesion performance was detected. The results show that,due to the absence of a direct force application point and the uniform distribution of vertical stress,the cylinder topological structure achieves an interfacial adhesion strength of 120.2 kN/m,which is 10.2%,48.8%,and 52. 8%higher than that of the cone( 109.1 k N/m),frustum( 80.8 k N/m),and dome-topped cylinder( 78.7k N/m),The adhesion strength of the 3D fabric printed based on this structure is significantly better than the requirements for functional garment accessories specified in the ISO 13935-2 standard,and can effectively improve the bonding fastness between the 3D-printed coating and the fabric.更多还原
