开发具有优异的单向汗液输送能力的Janus织物是在运动期间提供舒适感和保护健康的有吸引力的方式。在这项工作中,首先提出了3D润湿梯度Janus织物（3DWGJF），以解决女性乳房汗液积聚过多的问题，然后与海绵垫集成，形成3D润湿梯度Janus运动胸罩（3DWGJSB）。3D润湿梯度使制备的织物能够以单向模式（x/y方向）控制汗液的水平迁移，然后单向向下（z方向）渗透，最终将3DWGJF(皮肤侧)内侧的含水量保持在约0%。此外,制备的3DWGJF具有良好的水蒸气透过率(WVTR:0.0409gcm-2h-1)和优异的水分蒸发率(0.4704gh-1)。由于转移印花对织物的高附着力及其优异的机械性能，3dwgjf是非常耐用和能够承受超过500洗涤周期和400磨损周期。这项工作可能会激发下一代水分管理面料的设计和制造，具有有效的排汗功能，为女性的健康。
Developing Janus fabrics with excellent one-way sweat transport capacity is an attractive way for providing comfort sensation and protecting the health during exercise. In this work, a 3D wetting gradient Janus fabric (3DWGJF) is first proposed to address the issue of excessive sweat accumulation in women\'s
breasts, followed by integration with a sponge pad to form a 3D wetting gradient Janus sports bra (3DWGJSB). The 3D wetting gradient enables the prepared fabric to control the horizontal migration of sweat in one-way mode (x/y directions) and then unidirectionally penetrate downward (z direction), finally keeping the water content on the inner side of 3DWGJF (skin side) at ≈0%. In addition, the prepared 3DWGJF has good water vapor transmittance rate (WVTR: 0.0409 g cm-2 h-1) and an excellent water evaporation rate (0.4704 g h-1). Due to the high adhesion of transfer prints to the fabrics and their excellent mechanical properties, the 3DWGJF is remarkably durable and capable of withstanding over 500 laundering cycles and 400 abrasion cycles. This work may inspire the design and fabrication of next-generation moisture management fabrics with an effective sweat-removal function for women\'s health.
