| Résumé : |
This paper mainly analyzes the moisture permeability of different parts of sheepskin based on microscopic and water contact angle. Firstly, the moisture permeability of the neck, belly, back and hip of natural sheepskin was tested and the change rule of moisture permeability was analyzed. Then the SEM electron microscope pictures and water contact angle data were obtained. Through the analysis of the fibre distribution, the tight arrangement of fibres and the tension of leather surface in different parts of natural sheepskin, the reasons for the formation of this moisture permeability rule were explained. The study found that under the same temperature and humidity conditions, the moisture permeability of sheep skin in different parts is different. On the whole, the moisture permeability of different parts of sheep skin showed the order of belly > hip > back > neck. Microstructure analysis showed that the order of fibre tightness in different parts was neck > back > hip > belly. The natural sheepskin fibres in the belly and hip are loosely arranged, and their water contact angles are also small, which facilitates the passage of water vapour, so they have excellent performance in moisture permeability; the fibres on the back and neck of natural sheepskin are closely arranged, with less voids, and the water contact angle of the skin is also large, which affects the passage of water vapour. Therefore, the performance of moisture permeability is not as good as that of the belly and hip. |
