**3.5 Other fabric properties related to sensorial comfort**

It is evident from studies on the subjective evaluation of fabric handle that warm-cool feeling of a fabric very often makes an important contribution to the perception of its over-all handle and quality in the context of a given end use (Bishop, 1996). Alambeta instrument developed by Hes can be used for measuring the warm-cool feeling (Bishop, 1996; Özçelik et al., 2008; Mazzuchetti et al., 2008; Hes, 2004). This feeling, which is generated when fabric initially contacts the skin, is related to the heat flow between the skin and the contacted object. Rough fabric surface reduces the area of contact appreciably, and a smoother surface increases the area of contact and the heat flow, thereby creates a cooler feeling. The correlation between transient heat flux and the warm/cool feeling was investigated by several researchers (Barker, 2002; as cited in Rees, 1941; as cited in Hollies et al., 1953; as cited in Kawabata et al. ,1985). It has been reported that transient heat flux significantly affects clothing comfort in next-to-skin fabrics (Barker, 2002; as cited in Kawabata et al., 1985).

Prickle is a rather negative attribute associated particularly with fabrics containing a proportion of coarse animal fibres, having diameters of about 30 µm or more. When evaluating the handle and quality of wool containing fabrics, there has been obtained good correlation and therefore prickle characteristics of the fabrics should also be taken into consideration in objective handle measurements (Bishop, 1996). Although the luster and fuzzes of the fabric surface are not generally included in objective handle measurements, since the appearance of fabrics make an important contribution to consumers` garment preferences, the measurement of these properties should also be of interest in handle evaluation. The fabric noise and odour are not redundant in the subjective evaluation of textiles but these properties can be useful to evaluate fabric handle (Mitsuo, 2006).

Fabric handle according to fabric sound has been investigated in recent days. Fabric sound in the forms of sound spectra through Fast Fourier Transform analysis was analyzed (Mitsuo, 2006; as cited in Yi & Cho, 2000). Level pressure of total sound, level range and frequency differences of fabric sound were compared to mechanical parameters measured by KES system (Mitsuo, 2006; as cited Cho et al., 2001, 2005). The physiological responses evoked by friction sounds of warp knitted fabrics to that of electroencephalog, the ratio of high to low frequency were also studied (Mitsuo, 2006).
