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. Cuvinte-cheie: confort senzorial, tușeul țesăturii, țesătură din nano-filament de poliester, țesătură 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.

“…The Kawabata Evaluation System (KES) was designed for the standard evaluation of fabric hand [6]. It is composed of four instruments [13]. Six characterization tests can be performed thanks to these different devices: tensile and shear tests, pure bending test, compression test, and friction and roughness measurements.…”

Fabric-to-fabric friction is involved in the action mechanism of medical compression devices such as compression bandages or lumbar belts. To better understand the action of such devices, it is essential to characterize, in their use conditions (mainly pressure and stretch), the frictional properties of the fabrics they are composed of. A characterization method of fabric-to-fabric friction was developed. This method was based on the customization of the fourth instrument of the Kawabata Evaluation System, initially designed for fabric roughness and friction characterization. A friction contactor was developed so that the stretch of the fabric and the applied load can vary to replicate the use conditions. This methodology was implemented to measure the friction coefficient of several medical compression bandages. In the ranges of pressure and bandage stretch investigated in the study, bandage-to-bandage friction coefficient showed very little variation. This simple and reliable method, which was tested for commercially available medical compression bandages, could be used for other medical compression fabrics.

This paper discusses a strategy by which a robotic hand can use the physical properties of a fabric to pinch the fabric. Pinching may be accomplished by using a wiping motion, during which the movement and deformation of a deformable object occur simultaneously. The wiping motion differs from the displacement of a deformable object. During the wiping motion, there is contact, but no relative movement, between the manipulator and the object, whereas, during displacement, there is both contact and relative movement between the object and the floor. This paper first describes wiping motion and distinguishes wiping slide from wiping deformation by displacement of the internal points of an object. Wiping motion is also shown to be an extended scheme of pushing and sliding of rigid objects. Our strategy for pinching a fabric is accomplished with a combination of wiping deformation and residual deformation of the fabric under unloaded conditions. Using this strategy, a single-armed robotic hand can pinch both surfaces of the fabric without handover motion.
