Investigation of Thermal Comfort Properties of Electrospun Nanofiber Mats

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

“…It was known that thinner nanofibers would result higher wind resistance (resistance to air permeability) though still breathable. [ 14 ] However, thinner nanofibers would show less strength and would breakdown easily because of the elasticity of the knitted fabrics. Thus, we selected to coat the fabrics with relatively thick (800 nm) nanofibers.…”

“…It was known that thinner nanofibers would result higher wind resistance (resistance to air permeability) though still breathable. [14] However, thinner Pore size measurements of raw, blind, 10, 20, and 30 min nanofiber coated CO, CV, CMD, and CLY single jersey fabrics were given in Table 4. Raw CO, CV, CMD, and CLY fabric MFPs were ranged between 45.2 and 84.2 μm.…”

“…The complete electrospinning apparatus was enclosed in a glass box, and the electrospinning of the fibers was carried out at room temperature. In our previous study, [ 14 ] the 1, 3, and 5 hr' trials of TPU and poly(vinyl alcohol) coated nanofiber membranes showed that the deposition time did not create a significant change in water vapor permeability and the mass per unit area (fabric weight) of the nanofiber layer was lower than 1–2 g/m 2 . Thus, 10, 20, and 30 min deposition times were selected for various nanofiber thicknesses.…”

“…[ 13 ] For this aim, coating of nanofibers or nanofiber membranes onto knitted fabric could be used to improve the wind‐resistance properties. Nanofibers could dramatically decrease the air permeability without influencing the water vapor permeability [ 14 ] (Figure 1). Because of their thin fiber diameter, nanofibers have high surface area [ 15 ] providing water vapor transmission and along with the resistance to pressured air.…”

Tailoring the Porosity and Breathability of Nanofiber Webs with Mesh Size of the Deposition Material

“…Electrospun nanofiber webs show controllable high porous character with high interconnectivity [11]. These nano and micropores of the electrospun webs provide good moisture vapor transmission rate, while it maintains resistance to pressured air and resistance to liquid for some type of clothing [12].…”
