Garment design

Garment design influences the thermal resistance and evaporative performance of clothing. Tight fit garment shows more thermal resistance than loosely fitted garment. In case of loosely fitted garments due to body movement, pumping action forces out the worm air and moisture reducing thermal resistance of clothing. Mesh structure or vent may be used in the clothing both in the lining and shell fabric in various position. During body movement those mesh structure allows heat and moisture to pass through due to pumping effect. Thus thermal comfort is maintained. Figure 3.3

Some designer invented three dimensional vents for improving the body ventilation. An example is the use of flap over the mesh structure design of clothing. If the flap is used at arch position ventilation will be more than normal position use. Use of Velcro facilitates to form arch position. The arch shape provides a tunnel over the mesh and hot air could come out of the clothing.

SLEESEN designed a scoop like vent on the shoulder of a jacket for the motor cyclist. During cycling the air entering through the scoop like vent at the shoulder position comes out at the hem area taking out body heat and moisture away ensuring comfort. This design is shown in

Location of the vent or mesh panels has also effect on heat and moisture transfer from the body. If the vents or mesh panels are placed in the two side seam areas, best ventilation effect is found. Arm and sleeve movement improves the pumping effect at the side seam areas.
