Developing Breathable Double‐Layered Fibrous Membranes Equipped with Water Pulling Mechanism Toward Clothing with Enhanced Comfort

Abstract

Quick transfer of sweat from skin to atmosphere and dryness of textile inner surface are of scientific and commercial interests. However, creating a balance between these two parameters remains a serious challenge. In this work, electrospun double-layered membranes constructed of poly(vinylidene fluoride) fibrous layer (as inner hydrophobic layer) and nylon6 nanofibrous layer (as outer hydrophilic layer) are produced. Once a thin hydrophobic layer is considered, the enhanced water pulling mechanism is balanced out by increased wetted area in the inner surface. This is handled through selecting an optimum thickness for the inner layer. The designed double-layered membrane is a promising candidate for developing modern breathable textiles with enhanced moisture management properties such as sportswear.

Tailoring double‐layered fibrous mat of modified polypropylene/cotton fabric for the function of directional moisture transport

“…Compared with the AOTI value of DPP 2.5 /DCotton fibrous mat (spinning time of 2.5 hr), there is a decrease in DPP 3 / DCotton and certain quantity of water is retained in the top layer, ascribed to highly thick PP layer hindering water penetration. [30,31] 3.4 | Comprehensive analysis on directional moisture transport in fibrous mat Figure 7a visibly demonstrates the water transport progress in designed fibrous mat. It can be observed that when certain amount of droplets (200 μl) are dripped onto the surface of hydrophobic side, the droplets smoothly passes through the top layer rather than spread much on this side owning to its hydrophobic property, and only small ink stain appears on the surface.…”

Waterproof and Breathable Electrospun Nanofibrous Membranes

“…Conventional direction water transport fabrics are capable of transmitting body water and moisture mono‐directional, thus the perspiration is pulled away from the skin to the atmosphere rapidly. However, they are typically devoid of effective waterproofness in the inverse direction, resulting in poor protective function . Recently, W&B nanofibrous membranes have been successfully applied to solve this problem.…”

“…However, they are typically devoid of effective waterproofness in the inverse direction, resulting in poor protective function. [130] Recently, W&B nanofibrous membranes have been successfully applied to solve this problem. A typical example was given by the study of constructing trilayered W&B nanofibrous membranes with progressive wettability, transferring human sweat for quick evaporation and hindering outside liquid water penetration simultaneously.…”
