Design, Development and Preparation of Pouched Scuba-Knitting Spaced Fabric

Abstract Objective To improve the protection of human joints and avoid the injury caused by falls in the elderly. By testing and evaluating the wearability and mechanical properties of the pouched scuba-knitting fabric with no filling material, filled with EPS and POM, this paper provides a theoretical basis for the development of the protection products for the elderly. Methodology Using nylon filament and spandex stretch yarn as raw materials, two kinds of cushioning materials, EPS and POM, are respectively filled into pouched scuba-knitting weft-knitted structure. Results Due to the limit of 3mm spacing between front and rear needle beds of the computerized flat knitting machine, among all kinds of samples tested, the air permeability of EPS is stronger than that of POM with the increase of EPS sphere diameter. Because EPS spheres are more easily attached to water, the moisture permeability is shown to be the best. The mass loss of non-filled fabric is the greatest in the wear resistance test. Due to the characteristics of weft-knitted fabrics, there is no obvious difference among the three kinds of knitted fabrics in the tests of bursting, stretch recovery, pilling. Conclusion The pouched scuba-knitting structure filled with EPS is more suitable for the design and production of the protective fabric for the elderly afterwards.
