Preparation and Characterization of Knitting Fabrics with Good Tactile Comfortability for Automotive Seat Application
Automotive seating fabrics, that come into direct contact with the human body, which have increased requirements for their tactile comfort properties, but it is still a great challenge to clear the relationship between structures and its performances. Hence, 44 knitting fabrics with the different structural parameters were prepared first, and then the properties such as tactile, bending and compressive performance were tested, and the intrinsic correlation between their performance indexes and the structural properties was analyzed. The results showed that the toughness of the fabrics varied greatly, and the main score was concentrated on 75 to 90. As for the bending stiffness, the warp bending hysteresis of fabrics was concentrated in the range of 0–0.15 gf·cm cm?1, while that of the weft bending hysteresis was mainly concentrated in the range of 0–0.1 gf·cm cm?1. Moreover, the compression behaviors of fabrics were 0.7 to 1.5 gf·cm cm?2, 47.5 to 55% and 0.25 to 0.65, respectively. Tactile analysis of fabrics was carried out by establishing a comprehensive evaluation model, the average composite ratings of weft-plane fabrics, mesh fabrics, jacquard fabrics, and pile fabrics are 0.14, 0.176, 0.175, and 0.15, respectively. The mesh and jacquard fabrics were observed to have the better tactile comfort properties. In conclusion, the toughness, softness, and bending stiffness of the fabrics had a great influence on the tactile comfort, providing a reference for the development of automotive seat fabrics with good comfort performances.
