Coating is a technique widely used in the textile industry for different purposes, mainly in coloring and functional finishes. Graphene is usually applied to fabrics using coating techniques to provide such fabrics with properties like thermal or electrical conductivity. All woven fabrics have peaks and valleys in their structure, generated by the warp and weft threads interlacing. When spreading the graphene coating, the paste is placed in the fabric’s interstices, and the connection between conductive particles is only produced when the height of the coating is sufficient to connect the different areas where it is deposited. This article analyzes three types of satin weave with three interlacing coefficients (ICs) (0.4, 0.25, 0.17) and two sets of weft yarns each (20 and 71.43 tex). For a blade gap of 1.5 mm, the electrical resistance of samples with weft yarn count of 20 tex and IC of 0.4 is 534.33 Ω, while for IC = 0.25 electrical resistance is 36.8% higher and for IC = 0.17 this parameter increases 249.3%. For samples with weft yarn count of 71.43, the sample with IC = 0.40 exhibits an electrical resistance of 1053 Ω, for IC = 0.25 this value rises to 33.9% and for IC = 0.17 the electrical resistance value increases a total of 78.9%. This finding can be of interest for coatings where continuity is crucial, and for the application of substances that need to be protected from external factors, for which fabrics with deep interstices can be designed to house said products.

织物结构对石墨烯涂层纺织品电阻的影响

涂层是一种广泛用于纺织工业的技术,用于不同目的,主要用于着色和功能性整理。石墨烯通常使用涂层技术应用于织物,为此类织物提供导热或导电等特性。所有机织织物的结构都有峰谷,由经纱和纬纱交织而成。在铺展石墨烯涂层时,将糊状物放置在织物的空隙中,只有当涂层的高度足以连接其沉积的不同区域时,才会产生导电颗粒之间的连接。本文分析了具有三个交织系数 (IC)(0.4、0.25、0.17)和两组纬纱(20 和 71.43 tex)的三种缎纹组织。对于 1.5 毫米的刀片间隙,纬纱支数为 20 tex 且 IC 为 0.4 的样品的电阻为 534.33 Ω,而 IC = 0.25 的电阻高 36.8%,IC = 0.17 该参数增加 249.3%。对于纬纱支数为 71.43 的样品,IC = 0.40 的样品显示出 1053 Ω 的电阻,对于 IC = 0.25,该值上升到 33.9%,对于 IC = 0.17,电阻值总共增加了 78.9%。这一发现可能对连续性至关重要的涂层以及需要保护免受外部因素影响的物质的应用感兴趣,为此可以设计具有深空隙的织物来容纳所述产品。对于纬纱支数为 71.43 的样品,IC = 0.40 的样品显示出 1053 Ω 的电阻,对于 IC = 0.25,该值上升到 33.9%,对于 IC = 0.17,电阻值总共增加了 78.9%。这一发现可能对连续性至关重要的涂层以及需要保护免受外部因素影响的物质的应用感兴趣,为此可以设计具有深空隙的织物来容纳所述产品。对于纬纱支数为 71.43 的样品,IC = 0.40 的样品显示出 1053 Ω 的电阻,对于 IC = 0.25,该值上升到 33.9%,对于 IC = 0.17,电阻值总共增加了 78.9%。这一发现可能对连续性至关重要的涂层以及需要保护免受外部因素影响的物质的应用感兴趣,为此可以设计具有深空隙的织物来容纳所述产品。
