The use of the three-dimensional (3D) printing technique is gaining popularity due to its ability to produce products with minimum waste. 3D printing can be used to add polymers onto woven fabrics to produce novel structures. This research work concentrated on the study of the fabric properties affecting the adhesion of Polylactic Acid (PLA) polymer onto selected fabrics. Different fabrics made from cotton, polyester and acrylic, were selected and using 3D printing, PLA polymer was printed onto the fabric surface. Regression models were used to study the effect of selected fabric properties on the adhesion of PLA polymer onto the woven fabrics. The results obtained in this research work indicated that fabric areal density, warp count (Tex), weft count (Tex), fabric thickness and fabric handle indicated a positive correlation with adhesion of PLA onto woven fabrics. On the other hand, warp ends/inch and weft picks/inch showed a negative correlation with the adhesion of PLA polymer onto woven fabrics.

使用回归研究织物参数对3D打印PLA聚合物在机织织物上的附着力的影响

三维（3D）打印技术的使用由于其能够生产最少浪费的产品而受到欢迎。3D打印可用于将聚合物添加到机织织物上以产生新颖的结构。这项研究工作集中在对影响聚乳酸（PLA）聚合物在选定织物上的粘附力的织物性能的研究。选择由棉，聚酯和丙烯酸制成的不同织物，并使用3D打印，将PLA聚合物印刷到织物表面。回归模型用于研究所选织物特性对PLA聚合物在机织织物上的附着力的影响。这项研究工作获得的结果表明，织物的面密度，经纱数（Tex），纬纱数（Tex），织物的厚度和织物的手感与PLA在机织物上的附着力呈正相关。另一方面，经纱末端/英寸和纬纱纬纱/英寸与PLA聚合物在机织织物上的粘附力呈负相关。
