Problems solved by technology

In practice, the resulting composition cannot be used in shoe applications due to poor mechanical properties, especially toughness, elongation and hardness
[0007] The prior art does not disclose the use of 3D spacer fabric reinforced PU composites in shoe materials (especially in soles)

Embodiment

[0070] 1. Measurement method

[0071] During the experiments, the toughness, density, hardness and mechanical properties of the 3D fabric-reinforced PU composites were measured.

[0072] The density of the 3D fabric-reinforced PU composite was measured from the top layer to the bottom layer by using a DPX300LTE density analyzer. According to the test standard, a sample with a size of 5cm (length) x 5cm (width) x 1cm (thickness) should be prepared, then placed in the chamber and scanned by X-rays. Thus, a density profile is obtained.

[0073] The hardness of the 3D fabric-reinforced PU composites was measured in the direction of spaced yarns according to the test standard of ASTM D 2240 by using an Asker C durometer obtained from KOBUNSHI KEIKI Co, Ltd.

[0074] The tensile strength of the 3D fabric-reinforced PU composites was measured in the direction of spaced yarns according to the test standard of DIN 53504 by using a Zwick / Roell testing machine obtained from Zwick Roell...

Abstract

The invention relates to a 3D spacer fabric reinforced composite, to a process for producing it, to its use as in footwear, in particularly in shoe sole, and to a footwear, in particularly a shoe solecomprising it.

Description

technical field [0001] The present invention relates to a 3D spacer fabric reinforced PU composite material, its preparation method, its use in a shoe material (in particular a shoe sole) and a shoe material (in particular a shoe sole) comprising said composite material. Background technique [0002] Polyurethane (PU) foam is an important material and is widely used in various fields. PU foam has excellent properties, such as good thermal insulation performance, light weight, high specific strength and easy handling. In addition, PU foam has characteristics such as thermal, acoustic and electrical insulation, heat resistance and solvent resistance. Accordingly, PU foams are widely used, for example, as heat insulating materials in refrigerators and industrial equipment such as storage containers and pipes, as construction materials such as vehicle roofs, and as interior trims in automobiles. [0003] More specifically, PU foam is used in shoe materials as soles due to its ...
