INVESTİGATİNG THERMAL COMFORT AND SURFACE PROPERTİES OF 3/1 Z TWİLL WEAVED DENİM FABRİCS

Denim fabrics are used in jean production, it is a very preferred product because it is easy to use and does not require ironing, especially in daily wear. But there is a limited study about the thermal and sensorial comfort of denim in the literature. In this study, four fabric types were provided from the manufacturer to be used in the tests. The aim of this paper is to investigate the effect of construction on thermal comfort and sensorial comfort properties of denim fabrics. For this purpose, air permeability, thermal comfort, and water vapor permeability properties of 3/1 Z twill weaved denim fabrics have been examined. Also, the Kawabata KES-FB4 system was used for the evaluation of the surface properties of tested fabrics. It was found that the fabric with high surface roughness (F2) had a low thermal absorptivity value, and the fabric with low surface roughness (F3) had a high thermal absorptivity value. On the other hand, the lowest friction coefficient (MIU) was found in the lowest thickness value F4 coded fabric.

INVESTİGATİNG THERMAL COMFORT AND SURFACE PROPERTİES OF 3/1 Z TWİLL WEAVED DENİM FABRİCS

Denim fabrics are very preferred in recent years because it is easy to use and does not require ironing. But there is a limited study about the thermal and sensorial comfort of denim fabrics in the literature. The aim of this paper is to investigate the effect of the denim fabric composition on thermal comfort and sensorial comfort properties of denim fabrics. For this purpose, air permeability, thermal comfort, and water vapour permeability properties of 3/1 Z twill woven denim fabrics have been examined. Also, the Kawabata KES-FB4 system was used for the evaluation of the surface properties of fabric samples. It was found that the fabric with high surface roughness (F2) had a low thermal absorptivity value, and the fabric with low surface roughness (F3) had a high thermal absorptivity value. On the other hand, the lowest friction coefficient (MIU) was found in the lowest thickness value F4 coded fabric.
