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.
Highlights
Nowadays, consumers of mattresses cover product, demand high level of comfort, for protecting but to have an exquisite mattress fabric
Its comfort parameters are included as elasticity, softness, air permeability, aesthetic appearance like whiteness, thermal insulation and water vapor permeability
Fabric parameters such as fabric density, fabric thickness and fabric weight have been correlated to air and water vapor permeability, and to moisture management properties which includes accumulative oneway transport index and overall moisture management capacity
Summary
Consumers of mattresses cover product, demand high level of comfort, for protecting but to have an exquisite mattress fabric. Comfort is mainly affected by type of fiber, yarns properties and structure of fabric Fabric parameters such as fabric density, fabric thickness and fabric weight have been correlated to air and water vapor permeability, and to moisture management properties which includes accumulative oneway transport index and overall moisture management capacity. This is important to determine the overall thermo physiological comfort performance of knitted fabrics [1,2,3]. The use of different types of fibrous compositions (performing fibers or a suitable combination of natural and synthetic or artificial fibers) to improve the functional and comfort properties of mattress covers have been considered in our study. What we want to highlight in our experiment is the possible correlation between the whiteness values of the cover materials for bedding applications, type of raw material, fabric mass and the air permeability as performance of knitted fabrics
