Highly Durable Janus Fabrics Based on Transfer Prints for Personal Moisture Management

Abstract

Janus fabrics with moisture management ability have great potential for improving both physiological and psychological comfort of human body. However, current methods for creating Janus fabrics are typically complex, environmentally unfriendly, and costly. More importantly, the prepared Janus fabrics have demonstrated insufficient mechanical properties and poor fastness, rendering them unsuitable for practical applications. Here, this work proposes a method for constructing Janus fabrics through thermal transfer printing of hydrophobic transfer prints onto a superhydrophilic cotton fabric, followed by creation of a conical micropore array on the fabric surface. The as‐prepared Janus fabrics exhibit excellent unidirectional liquid transport capacity, capable of transporting 50 µL water completely in 11.6 s in the positive direction. Attributed to the durable property of the transfer prints, the Janus fabrics are capable of withstanding over 900 friction cycles and 250 home laundry cycles, which is a great advance in this research field. Additionally, the fabrication process has no detrimental effect on the fabric's breathability, elasticity, and flexibility. Furthermore, the Janus fabric can maintain human body temperature 3.6 °C cooler than that worn with cotton fabric. The fabrication method can provide useful insights for the design and creation of durable Janus fabrics to maximize personal comfort.

Graphene Oxide Nanopowder-Based Hydrophobic Fluid Diode Fabric with Passive Radiative Warming for Simultaneous Thermal and Moisture Management during Cold Weather

“…The tests were stopped when the test fabric had warming properties similar to those of the TMMF2.4/1.5 (i.e., the minimum GO nanopowder concentrations required to produce the passive radiation warming effects in this experiment). The fabric was placed on 1000 mesh sandpaper and moved horizontally and vertically along the sandpaper for 10 cm while a 100 g weight was pressed down on it for one cycle . The WCA of the coated side and the temperature of the uncoated side remained constant at 122.7 ± 1.8° and 30.5 ± 0.1 °C, respectively (and were similar to unworn test results for theTMMF2.4/1.5), after 120 abrasion cycles despite the progressive increase in the number of abrasion cycles (Figure a).…”

Nanotechnology for High‐Performance Textiles: A Promising Frontier for Innovation

“…Zhou et al. explored an environmentally friendly method for creating Janus fabric with improved moisture management ability through thermal transfer printing of hydrophobic transfer prints onto a superhydrophilic cotton fabric, resulting in Janus fabrics capable of unidirectional liquid transport, durable against friction and home laundry cycles, while maintaining breathability, elasticity, flexibility, and providing a cooling effect of 3.6 °C compared to regular cotton fabric [227] . In sports textiles, nanotechnology is making significant improvements in thermal and moisture management over conventional routes.…”

Composite Warp-Knitted Textile with Wet–Thermal Comfort, Support, and Antimicrobial Activity for Personal Long-Term Healthcare

“…to avoid skin or wounds soaked in moisture, resulting in eczema, skin inflammation, infection, ulceration, etc. , Moisture management materials as an emerging functional material have attracted wide attention. − They can quickly drain liquid away from the skin to avoid moisture accumulation, keeping the skin dry and comfortable while reducing the occurrence of diseases. , For example, a Janus wettability gauze could unidirectionally transfer the wound exudate away to accelerate healing . A textile with conical micropores allowed the export of sweat to cancel out the wet and sticky feeling . These excellent properties show that moisture management textiles have great potential for long-term care protection.…”
