Abstract

In order to design thermally desirable pillows, the relation between the sensory evaluation of the coolness of pillows and their thermal transport properties was investigated. The perception value <I>Pv</I> of coolness was correlated with the dry heat loss <I>Qd</I> of the pillow. The pillows with a large value of <I>Qd</I> were regarded as cooler. The <I>Pv</I> value tended to correspond to the apparent thermal conductivity <I>Ke</I> of the padding material used in the top side of the pillow. Pillows with a large value of <I>Ke</I> were regarded as cooler. The pillows with a small value for the contact area <I>CA</I> of the head and pillow showed a cooler feeling. The temperature <I>Tm</I> between the head and pillow after 30 minutes of use was measured. A pillow that had larger values for <I>Qd</I> and <I>Ke</I> and a smaller value for <I>CA</I> showed a lower value for <I>Tm</I>, and was regarded as being cooler.
