单轴天然织物扁担杆处理与氢氧化钠，乙酸，聚（乙烯醇）（PVA），聚碳酸酯（PC）的解决方案，并通过各种技术的特点。采用差示扫描量热法和热重法对织物的热性能进行了表征。采用衰减全反射-红外光谱法对织物成分进行了表征。利用扫描电子显微镜技术研究了织物的形态。进行X射线衍射研究以确定织物的结晶度。并对织物的化学组成和拉伸性能进行了研究。在各种处理的织物中观察到显著的变化。经PVA和PC处理后，织物的拉伸性能得到改善。织物的拉伸强度被发现在碱和乙酸处理上降低。作者在治疗前后进行了所有这些测试，除了化学成分。
The uniaxial natural fabric Grewia tenax was treated with sodium hydroxide, acetic acid, poly(vinyl alcohol) (PVA), and polycarbonate (PC) solutions, and characterized by a variety of techniques. Differential scanning calorimetry and thermogravimetry were used to characterize the thermal behavior of the fabric. Attenuated total reflectance-infrared spectroscopy was used to characterize the fabric constituents. The morphology of the fabric was studied using scanning electron microscopy technique. X-ray diffraction studies were carried out to determine crystallinity of the fabric. Chemical composition and tensile properties of the fabric samples were also studied. Significant changes were observed in the fabric with various treatments. Tensile properties of the fabric were observed to have improved with PVA and PC treatments. The tensile strength of the fabric was found to be decreased on alkali and acetic acid treatments. The authors conducted all these tests before and after treatments except the chemical composition.
