Mattress plays an important role in the quality of human sleep, warp-knitted spacer fabric (WKSF) is a rather important mattress material, this paper explored the indentation state of WKSFs of 20 mm thickness and 0.12, 0.15, 0.18, and 0.25 mm spacer filaments under the action of curved surface pressure by using spherical compression tests and finite element simulations, with the combination of three-dimensional and non-uniform pressure characteristics exerted on the mattress by the human body when lying down. Tests and simulations analysis would be shown in four aspects: firstly, when the spherical indenter acts on the WKSFs, the compressive stress, Indentation Force Deflection (IFD) and support factor (SF) of the WKSFs increase as the spacer filament fineness increases; secondly, the compression depth of WKSFs should be controlled within 40% when used as mattresses to obtain good compression comfort; thirdly, A warp-knitted spacer fabric with a 0.25 mm spacer filament fineness provides both comfort and pressure resistance and better meets the needs of most people for a spacer fabric for mattresses.

“…Many other special structures have also been developed and studied. [108][109][110][111][112][113] Spacer fabrics also known as three dimensional fabrics, consists of two separate textile sheets (which are kept connected vertically with spacer yarn), have positive qualities for their potential use in edema treatment. 108,109 These spacer fabrics can be manufactured with different methods i.e.…”

Background: Compression bandages, stockings, and pneumatic compression devices are common classifications of compression products, used alone or in combination. The structure of these compression products is complex: they are typically multi-layered, overlapped, stretched and applied to a three-dimensional curved surface part of the body. This research aims to review the materials, designs, and fabrication processes/technologies of a variety of compression devices used in management of chronic edema by considering contributions of materials/textiles, as well as prototyping technologies. Method: Relevant papers/patents for review were identified using keywords associated with materials, designs, and fabrication processes of textile-based compression devices/products for treatments of the edematous lower limb. Results: Modern Compression therapies employ textile materials with a variety of fiber types, yarns and fabric structures, and wide range of elasticity and extensibility (i.e. inelastic to elastic, short stretch to long stretch) to provide the required pressure to the lower leg. Compression fabrics are fabricated using a variety of production technologies and machineries, and they have a wide range of physical and performance attributes. Conclusions: Appropriate selection of materials and fabrication technologies for use in compression therapy is essential to enhance the success in the management of chronic edema. This review might aid in the development and implementation of textiles/materials, and improvement in design of the textile-based compression devices to increase the efficacy of compression therapies in the management of chronic edema, allowing patients to improve their long-term health.

“…The suitability of WKSF for pressure ulcer protection has been studied by several research groups. Hepburn et al [17] compared the pressure relieving cushion effect of WKSF and PU foams and found that WKSFs retained their thickness over longer periods to a larger extent than PU foams under both static and dynamic loading conditions. This is mainly due to superior resilience of the fiber material in the WKSFs.…”

Many pressure wound protection products, such as pressure redistribution supports and exuding wound dressings, are made of polyurethane sponge. However, polyurethane sponge does not possess a desirable combination of air permeability, moisture management and mechanical properties required by pressure redistribution supports and exuding wound dressings. This study explores the optimization of a 3D warp-knitted spacer fabric (WKSF) structure for pressure ulcer protection. The influence of construction and material parameters on the compression performance and air permeability of WKSFs was investigated by numerical simulation and then validated with experiments. The moisture transport and wetting properties of WKSFs were characterized by a moisture management tester. The numerical simulation and experimental results indicate that the WKSF structure can be tuned to achieve compressional properties, air permeability, and moisture management performance that are more suitable for pressure ulcer protection than polyurethane sponge. WKSFs constructed with a low-density surface layer, coarser spacer yarns, and larger spacer yarn inclination-angle are more suitable for pressure redistribution support surfaces, while WKSFs constructed with dense surface layers and coarse spacer yarn can better meet the performance requirements of exuding wound dressings.
