Three types of fabric blends, viz. polyester/modal, polyester/cotton and polyester/viscose, are selected. The selected fabrics are initially pretreated (scoured) to remove the impurities and then padded with a thermo-regulating finish (HeiQ Adaptive AC-06) at 2%, 4% and 6% concentrations. The coated materials are then characterized for geometrical properties and functional characteristics. The polyester/modal fabric coated with 6% finish concentration exhibits excellent thermal conductivity, thermal resistance, and thermal absorptivity characteristics.

A comparative analysis shows that the cues perceived by flattened fabrics are insufficient to stimulate the perception of softness during the purely visual condition. At the same time, the spatial deformation caused by the action significantly stimulates the perception of softness in the purely haptic state. While in the visual-haptic dual condition, the spatial deformation causes a folding formation that stimulates the perception of softness by matching the visual and haptic cue information. The study outcomes are theoretically defined as Perceptual Conflict of Interest (PCI), which further focuses on the PCI model of fabric perceptual prediction. Accordingly, this study also discusses different concepts of sensory cue tracking and their impact on cloth modality assessment.

The dyed yarns produced from singed and unsinged cone yarns, which, in turn, are produced with different levels of removal of comber noil have been converted into fabric. The pilling resistance, drape, and low-stress mechanical properties of fabric samples are studied. The fabrics produced from singed yarn possess higher pilling grades. The singeing of yarn increases the drapability of the fabric. The fabric produced from singed yarn shows a higher total hand value as compared to that of the fabrics produced from unsinged yarns. The results show that the removal of more amount of comber noil to produce yarn with lesser imperfection at the ring cop yarn stage does not necessarily result in the fabric with better pilling resistance and handle, whereas it can be achieved by the singeing process.

A three-factor three-level Box-Behnken factorial design has been employed to analyse and optimise the carding parameters. The work focuses on the comprehensive exploration of the functional properties in the light of nonwoven fabric structures. Regression models of nonlinear process are developed to establish the relationship between specific properties of nonwoven fabric and structural indices. The optimised carding parameters specific to fibre denier result in improved filtration performance of the nonwoven fabric having lower values of fabric thickness, mean flow pore size and pressure drop, besides acquiring higher filtration efficiency.
