ABSTRACT

In this work, an attempt has been made to develop nonwoven fabrics by needle punching technology and comfort characteristics of needle punched nonwoven fabrics are analyzed with respect to thermal conductivity, water absorbency, and air permeability. Box-Behnken experimental design was used to study the influence of parameters such as needle punch density, needle penetration depth and fabric areal weight on thermal conductivity, water absorbency, and air permeability. From the responses, it was noted that the maximum water absorbency of 494% and air permeability of 79 cm³/cm²/s and minimum thermal conductivity of 0.0251 W/mK was achieved at needle punch density 75 punches/cm², 8 mm needle penetration depth and fabric areal weight 150 g/m².

摘要

在这项工作中，尝试通过针刺技术开发无纺布，并分析了针刺无纺布的舒适特性，包括导热性、吸水性和透气性。Box-Behnken实验设计用于研究针刺密度、针刺深度和织物面积重量等参数对导热性、吸水性和透气性的影响。^{从响应中可以看出，在针刺密度为 75 针/cm 2}、8 mm时，最大吸水性为 494%，透气性为 79 cm ³ /cm ² /s，最小热导率为 0.0251 W/mK针刺深度和织物面积重量 150 g/m ².
