Abstract:
Fabric hand forms a significant component of clothing comfort. It is defined by the quality, aesthetics and appeal of a material. A good fabric feel creates asatisfying interaction between the garment wearer and their external environment. One form of fabric hand assessment is the subjective rating of fabrics when people use their five sensory modalities. This method forms an important aspect of fabric quality assessment and relies mostly on the spontaneous preference of a person whilst he examines the fabric. Another form of assessment is the use of FOM [Fabric Objective Measurement] technology with instruments like the KES-FB [Kawabata Evaluation System for Fabrics] to objectively measure textile parameters. However, the relationship between subjective rating and objective measurement has not been studied widely with regard to the direct role of the human sensory system and its contribution towards fabric hand. An attempt has been made to use the bio-medical engineering imaging technique, the functional Magnetic Resonance Imaging Technique to study human perception towards fabric textures. The study was conducted to identify and create a sensory paradigm suitable for fMRI scanning of fabrics. The experiment attempted to verify the use of passive touch [no finger movement] for four different fabric hands. These fabric hands were classified as smooth-unpleasant, smooth-pleasant, rough-unpleasant and rough-pleasant. The perceptual response of eight, healthy, right-handed male volunteers was studied for the specified textures. The prime hypothesis was that the somatosensory area in the brain responds to different textures. The project aimed to create a relationship linking subjective descriptions, sensory perception and objective measurements of textile materials. The parietal lobe was activated for all textures especially in Sl areas BA1, BA2 and BA3. Maximum activation was seen while rubbing the fabric on the fingers, followed by placement of fabric on fingers. These two conditions were compared to the baseline condition when there was no placement of fabric on fingers. The perception of pleasant fabrics was felt in the temporai lobe and parietal lobe. The perception of unpleasant fabrics was felt more in the frontal lobe and parietal lobe. The KES-FB was used to measure the mechanical parameters like roughness, bending, shear, compression and friction to support the fabric hand using fMRI and subjective rating of the fabrics.
