Abstract

The comfort and performance of textile products used as mattress covers is analyzed in terms of physical characteristics, so air permeability and whiteness are investigated for different knitted assemblies with different compositions. The knitted system analyzed consists of two knitted surfaces assembled by a filling thread, finally obtaining a consistent composite material. Several samples of different fibrous composition were tested, analyzing their behavior during future use. A connection has been experienced between permeability, thickness, and whiteness of composites knitted of cotton, bamboo, wool, viscose and polyester. Samples tested for air permeability were tested face up and face down, using Static Air Permeability Tester. The whiteness of the knitted samples was checked using the Reflection Spectrophotometer trough the method that defines white and yellow indices. Samples containing bamboo and wool blended polyester have higher yellow markings. Thus, it may be recommended that future composite mattress knitted fabrics be treated with anti-aging to extend the product life cycle, as well as other friction wear-related experiments.
