A novel approach for developing high thermal conductive artificial leather by utilizing smart electronic materials

Abstract

Nowadays, artificial leather is an important commodity in daily life, especially in the fields of apparels, stationery and furniture. However, due to the maturity of producing technology and market segmentation, the industry trends to be saturated. Leather product manufacturers face intense competition and increasing production costs to survive on feeble profits. Thus, everyone is seeking a solution to break this predicament. Thanks to technical advancement and diversified intelligent electronics, a promising market opportunity has emerged that looks for innovative functional leather. This leather can exhibit high thermal conductivity and act as an essential component of electronic outside packages to prevent over-heating.This study aims to develop a high thermal conductive artificial leather (HTCAL). It incorporates smart electronic textile material (conductive yarn) into traditional artificial leather production through modifying the material and structure of its base layer. The result showed that the thermal conductivity of HTCAL was improved by 19.6% and, when wearing directly, a significant temperature gap between skin and the inner side of the leather occurred, which could offer a comfort cool feeling when worn in summer. This approach is a breakthrough to seize a new opportunity and offer an advancing direction. Further, this HTCAL can free the industry from periodical demand restriction, that is, seasonal limitation, and broaden product research and development into more fields. Thus, this approach can not only improve manufacturers' competitiveness and break them out of the current predicament, but also it creates new business opportunities.

Synchronization of thermal properties and constituents in Nanocomposite: Manufacturing, characterization, adjustable properties

“…Co., Ltd, Japan), See S10. 33 It should also be noted that, this study test 3 replicates per sample for thermal conductivity. Therein system, a 1 cm × 1 cm foam piece was cut from the middle of a 5 cm × 5 cm × 2.5 mm polystyrene foam plate.…”

The effect of PVC’s resin K-value on the mechanical properties of the artificial leather

“…There is some research that already discussed on artificial leather such as on surface modification (Sakmat et al, 2015), processing (Roh et al, 2014), thermal and mechanical properties modification (Ma et al, 2019;Maia et al, 2017;Pimapunsri et al, 2017;Yang et al, 2017). And some paper has also studied the effect of k-value into the rheological behavior of plastisol (Zadhoush et al, 2004) and molecular weight distribution (Pepperl, 2000).…”

The anisotropic structure of electro conductive leather studied by Van der Pauw method

“…Furthermore, the four-probe method is used by Schnabel [10] for evaluating anisotropy on parallel-plane crystals. Investigation of anisotropy of electrical properties of textile fabrics was the focus in Azoulay [11]. The author analysed the electrical properties in different weaving directions of the textile material.…”
