Buoyant swimwear is becoming more common in recreational swimming use, so the performance of buoyant fabric is important when designing functional swimwear. In this study, potential buoyant inlaid knitted fabrics for buoyant swimwear are investigated. Three types of knitted structures, half milano, full milano and 1 × 1 rib, are selected and various kinds of tubes and foam rods in different diameters are prepared for inlaying during the knitting process by using a 7 G hand-knitting machine. The mean differences among the levels of three independent variables, (1) inlaid material, (2) yarn and (3) knitted structure, on three dependent variables (net buoyant force, compression and tensile properties) are analyzed by using a multivariate analysis of variance. The result shows that the net buoyant force and mechanical properties of the fabric are significantly different due to the inlaid material and knitted structure, but not the yarn. The net buoyant force increases with fabric thickness and the outer diameter of the inlaid material. The inlaid fabrics are less compressible than the control fabric and show better recoverability with an increase in the diameter of the inlaid material. For the tensile properties, the inlaid material reinforces the fabric in both the wale and course directions, in which the stiffness in the course direction is significantly increased. The inlaid fabric is stronger and resistant to breakage in the course direction when the diameter of the inlaid material is increased. The findings of this study contribute to developments in the textile and sportswear industry.

浮力泳装在休闲游泳中变得越来越普遍，因此，浮力织物的性能在设计功能性泳装时很重要。在这项研究中，调查了用于浮力泳装的潜在浮力镶嵌针织物。选择半编织，全编织和1×1罗纹三种编织结构，并使用7 G手工编织机准备各种直径不同的管子和泡沫棒进行编织。通过对以下三个变量（净浮力，压缩和拉伸性能）分析三个独立变量（1）镶嵌材料，（2）纱线和（3）针织结构的水平之间的平均差异。方差。结果表明，由于镶嵌材料和编织结构的影响，织物的净浮力和机械性能存在显着差异，而纱线却没有。净浮力随织物厚度和镶嵌材料的外径而增加。镶嵌织物的压缩性低于对照织物，并且随着镶嵌材料直径的增加，其显示出更好的可恢复性。对于拉伸性能，镶嵌材料在纵行和横行方向都增强了织物的强度，在横行方向上的刚度大大提高了。当镶嵌材料的直径增加时，镶嵌织物更坚固并且在行进方向上不易断裂。这项研究的发现有助于纺织和运动服装行业的发展。
