“…PU possesses a wide range of desirable properties such as high hydrophobicity, adjustable pore structure, and reinforced mechanical properties, which have already been used in manufacturing industry . However, the waterproofness of pure PU nanofibrous membranes remains insufficient to allow them to compete with commercial membranes in practical applications .…”

The polyurethane (PU)/hydrophobic silica gel (HSG) fibrous membranes with the hydrophobic and breathable surface was fabricated via electrospinning. By employing the HSG incorporation, mechanical properties, thermal stability, and waterproofness of the composite membranes could be improved. The porous structure of the membranes would be regulated by tuning the temperatures of thermal treatment. When HSG content increased to 3 wt%, the PU/HSG composite membranes possessed remarkable tensile strength of 6.3 MPa and high water contact angle (WCA) of 134°. Furthermore, the maximum WCA (142° ± 1°), good hydrostatic pressure (5.45 kPa), large water vapor transmission rate (8.05 kg/m2/day), and high air permeability (9.25 L/m2/s) of the composite membranes could be achieved by heat treatment at 120°C. The resultant membranes performed significantly better when compared to the pure PU membranes under the same conditions, such as the higher tensile strength (100%), better waterproofness (200%), and stronger breathablity (25%).

“…Zhang et al [15] also argued that once viscose or cotton are used on the outer side, the fabric knitted with fine polypropylene (PP) filaments as the inner side touching the skin, has enhanced water holding capacity, wicking, and moisture vapor transmission. [4][5][6]19,20] Li et al [21] demonstrated that a reasonable equilibrium of breathable (water vapor transmission rate) and waterproof performance can be achieved by hydrophobic fibrous membranes prepared based on electrospinning technique. The impact of raw materials and knitting structure on the dynamics of water absorption in double-layered weft knitted fabrics was investigated by Bivainyt and Miku cionienė.…”

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.

The blend polyethersulfone (PES)/cellulose acetate (CA) flat‐sheet microporous membranes were prepared by reverse thermally induced phase separation (RTIPS) process. The effects of CA content and coagulation bath temperature on membrane structures and properties were investigated in terms of membrane morphology, water contact angle, permeation performance, and mechanical properties. The cloud point results indicated that the cloud point decreased with the increasing content of CA. When the coagulation bath temperature was lower than the cloud point, the membrane formation process underwent nonsolvent induced phase separation (NIPS) process and dense skin layer and finger‐like structure were formed in membranes. These membranes had lower pure water flux and poor mechanical properties. But when the coagulation bath temperature was higher than the cloud point, the membrane formation process underwent RTIPS process. The porous top surface as well as porous cross‐section of the membranes were formed. Therefore, high pure water flux and good mechanical properties were obtained. The contact angles results indicated that the hydrophilicity of the prepared membranes improved obviously with the addition of CA. When the content of CA was 0.5 wt% and the membrane formation temperature was 323K, the PES/CA microporous membrane which was prepared via the RTIPS process displayed a optimal permeability of the pure water flux of 816 L m−2 h−1 and the BSA rejection rate of 49.5%, which showed an increase of 48.9% and 23.6% than that of pure PES membrane, respectively. Moreover, the mechanical strengths of the membranes obtained by RTIPS process were better than those membranes prepared by NIPS process. POLYM. ENG.
