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-s… Show more
“…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].…”

Proprietățile de confort ale țesăturilor din nano-filament de poliester: evaluare senzorială În acest articol, este prezentată o lucrare experimentală pentru evaluarea proprietăților senzoriale ale țesăturilor din nano-filament de poliester. În acest scop, o țesătură din nano-filament de poliester a fost realizată și comparată cu țesături din: amestec poliester/bumbac (PC) şi, respectiv, poliester/viscoză (PV), utilizând sistemul de evaluare Kawabata (sistemul KES), cu scopul de a evalua tușeul pe baza caracteristicilor mecanice. Rezultatele au arătat că țesăturile realizate în amestec PC și PV au fost mai rigide decât țesătura din nano-filament de poliester. O valoare mai mare a tușeului (THV) a dus la o rigiditate mai mică (Koshi), la o netezire (Numeri) și la un grad de umplere (Fukurami) mai mari. Valorile tușeului țesăturii din amestec PV au fost mai apropiate de cele ale țesăturii din nano-filament de poliester față de cele ale țesăturii PC. Rezultatele generale ale caracteristicilor de rezistență la tracțiune, forfecare, încovoiere, compresiune și de suprafață ale țesăturilor din nano-filament de poliester au fost mai bune în comparație cu cele ale țesăturilor în amestec PC și PV.

Comfort properties of nano-filament polyester fabrics: sensory evaluationIn this article, an experimental work is presented to evaluate the sensorial properties of polyester fabric constructed by nano-filament yarn. For this purpose Nano Filament polyester fabric was fabricated and compared with the spun polyester/cotton (PC) and polyester/viscose (PV) blended fabric by using Kawabata evaluation system (KES-system) to assess the handle of the fabric based on mechanical characteristic. The results revealed that the fabric made from PC and PV blended fabric were stiffer than nano-filament polyester fabric. The higher hand value (THV) resulted in lower stiffness (Koshi), and higher smoothness (Numeri) and fullness (Fukurami).Hand values of PV blended fabric were close to nano-filament polyester fabric rather than PC fabric. The overall results of tensile, shearing, bending, compression and surface characteristics of nano-filament polyester fabric were found best as compared to PC and PV blended fabric.

Compression pressure exertion is strongly related to mechanical properties of compression socks deployed with various type of materials and machine adjustments. These socks work on the principle of highest pressure at the ankle and gradually decrease towards the calf portion. Compression socks are used for the prophylaxis and treatment of venous disorders. Venous disorders range from minor asymptomatic incompetence of venous valves to chronic venous ulceration. Current research work contains analysis of the force at practical extension compared to experimental pressure (Ps), the relationship between experimental pressure (Ps), force at practical extension, and tensile indices which include hysteresis (H), tensile resilience (TR), and tensile linearity (TL). Results showed that the force value at practical extension (FL) impart the significant influence on experimental pressure (Ps). It is also portrayed that the tensile indices (W, W′, H, TR, and TL) combined with force at practical and experimental pressure also shown to have contributed significantly to the explanation of experimental pressure (Ps) results. Compression sock tensile characteristics are highly significant and directly related to their productivity, effectiveness, and working life.
This research focuses on the integration between functional finishing and the performance properties of polyester fabric for comfortable clothes. The effects of nanofinishing (zinc oxide nanoparticles and nano-polyurethane nanocomposite) on the ultraviolet protection properties of polyester fabric, the whiteness index, and the Kawabata Evaluation System were studied. Under the optimum finishing conditions, excellent protection (150) was achieved at lower concentrations of the nanocomposite, and zinc oxide nanoparticles individually enhanced the whiteness index (73). The results of the Kawabata Evaluation System showed that the finishing processes improved mechanical and performance properties (tensile, shearing, bending, compression, surface roughness, thermal, and hand properties), indicating that all the finished fabrics offered enhanced functionality, thermal and comfort properties. Enhanced total hand value properties (3.7 for summer and 5.1 for winter) were realized by finishing, assuming the finished fabrics were applied to men’s shirts and women’s dresses for summer and winter apparel. Scanning electron microscopy and energy disperse X-ray spectroscopy analyses showed a uniform layer of zinc oxide nanoparticles and nano polyurethane on the fiber surface. Fourier transform infrared spectroscopy confirmed the structural changes in the finished fabric.
