Fabric Selection for the Reference Clothing Destined for Ergonomics Test of Protective Clothing—Sensorial Comfort Point of View

Abstract

The main purpose of this study is the selection of a proper fabric for the reference clothing for ergonomic tests of protective clothing. For research, seven fabric of different raw material content and different structure were chosen. We studied the handle of fabrics produced from blend of polyester/cotton and polyester/Tencel, which were designated by letters from A to G. The assessment of handle of the fabric was performed based on the mechanical properties of fabrics using Kawabata evaluation system (KES-system). It was proven that one of the tested fabrics (F) made of polyester and cotton fibers (85% PES / 15% cotton) with the reinforced twill weave is characterized by the highest total hand value (THV).The high THV results from the low value of koshi (stiffness) and the highest value of numeri (smoothness) and fukurami (fullness). However, in terms of physiological comfort, the lower value of fukurami is more preferred. It turned out that the fabric with the higher value of fukurami (including fabric F) is characterized by the lower air permeability and higher water vapor resistance. At the end, we decided that the reference clothing will be made of cotton/polyester fabric G with the lowest mass per square meter because of the very good physiological comfort parameters and the satisfactory sensorial comfort parameters.

Comfort properties of nano-filament polyester fabrics: sensory evaluation

“…Both the samples (sample 01 and sample 02) tensile strains were compared with already done studies. Both these samples exhibit higher values of tensile strain (EM) and tensile energy (WT) are greater than polyester/viscose blended suiting fabric and polyester/cotton blended fabric, portray our samples are best in comfort properties [18][19]. Linearity of tensile (LT) property of nano-filament polyester fabric is almost same as of polyester/ viscose fabric and less than polyester/cotton fabric [18][19].…”

Linearity of tensile (LT) property of nano-filament polyester fabric is almost same as of polyester/ viscose fabric and less than polyester/cotton fabric [18][19]. In case of tensile resilience (RT), the average values are lacking with better handle than P/V and P/C for both nano-filament fabrics [18][19].…”

“…Likewise bending rigidity value, bending hysteresis should be lower results in more fabric elasticity [17]. The values of bending rigidity (B) and bending hysteresis (2HB) are somehow less than polyester/ viscose blended suiting fabric and significantly less than polyester/cotton blended fabric which showed its better fabric handle [18][19].…”

“…For this we compared these two samples with polyester/viscose blended suiting fabric, the values of compression property LC (linearity of thickness/compression) and WC (compression energy) of nano-filament fabric are non-significantly greater than PV blended fabric. However; RC (compressional resilience) of PV fabric and PC fabric is almost doubled than nano-filament fabric samples [18][19].…”
