Analysis of Depth of Shade on Mercerized and Unmercerized Fabric among Different Woven Fabric Structures

investigation of thermal comfort properties of woven sport fabric using blend of estabragh fibers

امروزه لباس در نظر ورزشکاران و کسانی که برای اوقات فراغت خود و یا برای رسیدن به اندامی متعادل، ورزش می کنند؛ بسیار با اهمیت است. احساس مطلوب از لباس در زمره خصوصیات راحتی پوشش می باشد. خصوصیات انتقال رطوبت لباس، در ارزیابی راحتی حسی و حرارتی منسوجات تولید شده از آن ها بسیار مهم است. هدف از این تحقیق، معرفی پارچه جدید است که متشکل از الیاف استبرق با خواص منحصر به فرد می باشد. استبرق لیف طبیعی تو...

Analysis of Woven Fabric Strengths: Prediction of Fabric Strength under Uniaxial and Biaxial Extensions

This study of woven fabric strength begins by focusing on the effects of the crossing points, where warp and weft yarns interlace with each other to form a fabric, towards the ultimate fabric tensile strength. When a fabric is under uniaxial or biaxial tension, the yarn-yarn interactions at the crossing points are found to consist of two components, a pressure-independent adhesive component and...

Thermomechanical Properties of Woven Fabric Composites

The in-plane thermo-elastic behaviour of woven fabric reinforced composites is analysed using a combination of published micromechanics and finite element techniques. The repetitive unit of an arbitrary woven fabric composite is divided into elements of which the thermo-elastic properties are determined using micromechanics. The properties of the repetitive unit are obtained using the finite el...

Influence of the Dry Woven Fabrics Meso-structure on Fabric/fabric Contact Behaviour

The first stage of the RTM process concerns the preforming of the part. During the preforming of multilayered reinforcements, frictions between the plies occur. An experimental device designed to analyse the ply/ply, ply/tool and yarn/yarn frictions has been set up. Specific contact behaviour for ply/ply friction is directly related to shocks taking place between overhanging yarns of each sampl...
