Hydrophobic Nanofiber Layers

Investigation of thermal comfort properties of electrospun thermoplastic polyurethane fiber coated knitted fabrics for wind‐resistant clothing

“…[ 2 ] In knitted fabrics, less permeable structures with smaller pore size can be simply produced by reducing the stitch length, increasing the number of stitches per unit area, and increasing the fabric thickness or using double‐layered structures. [ 2,3 ] However, every kind of textile material has its own limitations [ 4 ] and unlike weft and warp yarns, it is also not possible to achieve too much close connections with knitting technique when compared to weaving technique. There is always a gap in the middle of the loop because of the specific shape of the loop.…”

“…In lamination, first an adhesive is applicated as a coating, then layers are bonded to form the laminate. [ 4 ] Commonly polymer‐based membranes are used. In many outdoor clothing, the aim of utilizing these membranes is to achieve high hydrostatic resistance, low air permeability, high vapor permeability, and wind resistance properties.…”

“…In many outdoor clothing, the aim of utilizing these membranes is to achieve high hydrostatic resistance, low air permeability, high vapor permeability, and wind resistance properties. [ 11 ] So that, wind permeation inside the clothing's microclimate and consequently body heat loss could be prevented. [ 12 ] However, such low air permeability usually results in low water vapor transmission, which make these clothing uncomfortable especially when the wearer generates a lot of heat and sweat.…”

“…[ 16 ] In recent years, some research has been done using nanofibers to fabricate protective clothes. [ 4,9,12,17–25 ]…”

“…They evaluated the hydrostatic resistance, air permeability, and steam permeability of four different laminates and showed that the nanofiber layer worked as a barrier layer. [ 4 ] Hong et al prepared functional fabrics by coating laminated multilayer nanoweb membrane with a water born polyurethane resin. They assessed the abrasion resistance, breathability, and waterproofness of the developed structure and compared with Gore‐Tex XCR.…”
