Abstract: In recent years, because of its unique advantages, laser engraving process is not only widely used in electronics, packaging, advertising, and other industries, but also more and more widely used in textiles, especially in the soft decoration industry in the home space. Combining the laser engraving process with the form of fabric wall, the fabric can present a multi-layer three-dimensional effect through laser engraving, breaking the previous two-dimensional flat pattern method and making the indoor space picture variable. The gloss and softness of the flannelette fabric can create a modern light luxury style. Therefore, this paper uses laser engraving technology to innovatively carry out appearance feature engraving experiments on flannel cloth to explore the effect form achieved by laser engraving on flannel.
By analyzing the influence of laser engraving on the appearance and characteristics of flannel at different levels, the three-dimensional effect of laser engraving on flannel was further explored. Experiments were carried out on 11 engraving levels on flannel, and the effect analysis was carried out from the color, thickness, and surface morphology of the fabric. The laser engravement process was applied to the flannel, and the three-dimensional layered effect of laser engraving on the flannel was realized through multi-level experimental exploration. Then the influence of laser engraving process on the appearance effect of flannel was analyzed. The results show that the layers of laser engraving have a great influence on the color brightness value of flannel, and four distinct categories are obtained through chromatic difference and cluster analysis, and no significant differences between B0-B50, B60 and B70, B90 and B100 engraving levels are found. The thickness of the fabric decreases as the engraving level increases, reaching its thinnest at B0 and its thickest at B90. At the same time, the change in the thickness of the fabric is also accompanied by the change in the brightness of the fabric. As the layers of laser engraving deepen, the fibers are gradually melted into flat surfaces, accompanied by tiny holes. The results of this study provide a basis for the application of laser engraving technology in flannel.
This paper chooses to study the impact of laser engraving process on the appearance effect of flannel, through laser engraving level analysis and thickness analysis, can make layered decorative paintings or wall cloth and other household practical products, which also provides new development ideas for the soft decoration industry. The research results can provide practical reference value for the subsequent application practice of laser engraving on different fabrics, and can be applied to more diverse scenarios.

摘要： 为了分析不同层级下的激光雕刻对绒布外观和特征的影响,探索激光雕刻在绒布上呈现的立体效果,在绒布上进行11个雕刻层级的实验,分别从织物的颜色、厚度与表面形态进行效果分析。结果表明:激光雕刻的层级对绒布的色彩明度值影响较大,并通过色差与聚类分析得出4个层次分明的类别;织物的厚度随着雕刻层级的增大而减小;随着激光雕刻的层级加深,纤维逐渐被熔融成平面,伴随着细小孔眼。该研究结果为激光雕刻技术在绒布上应用提供了依据。
