Prediction of the Shearing Property of Worsted Fabrics Using BP Neural Network

In this paper, three layers of BP neural network were used to model the shearing properties of worsted fabrics. We train the neural network models with 27 kinds of fabrics, and then use 6 kinds of fabrics to validate the accuracy of the model. The result shows that the predicted accuracy of the models is about 85%.     

Wet Permeability Characteristics of Double-layer Knitted Fabrics

In order to solve the problem that sweat flows back into the internal layer from the external layer in doublelayer knits, a fabric structure model is set up and the conditions that keep the sweat from flowing back into the internal layer from the external layer are presented. It can be used to improve the design of the double-layer knitstheoretically.     

Gray Synthetic Evaluation on Moisture Comfort of Sportswear Fabrics under the Condition of Heavy Sweating

Moisture and water transfer under the condition of heavy sweating are analyzed. Four different experiments are made to test moisture resistance, water-keep, wicking effect and drying ability of samples. Then gray analysis method is introduced to evaluate the comprehensive comfort of these fabrics. Result shows chemical fiber with high moisture transfer performance has advantage in water transfer and diffusion, which is suitable for human under the condition of heavy sweating. Though natural fiber can absorb moisture well, it cannot transfer fluid sweat. Therefore natural fiber fabrics such as cotton, wool are unsuitable to make functional sportswear.

关用“蛋白质织物”成功修补动物伤口

美国俄勒冈激光治疗中心科研小组在大鼠体内成功完成的一项修补试验，向人们展示了“蛋白质织物”的医疗前景，据称，对人体的试验有望明年进行。科学家说，如果“蛋白质织物”疗法的人体试验进展顺利，不久以后，人类也许只需用“蛋白质织物”即可修复难以恢复的内脏伤口。     

安全气囊织物气流充胀变形的研究

对气囊织物承受0～50 kPa的气流充胀过程进行了有限元模拟.得到了其充胀后的变形曲线及其薄膜应力分布,并通过实测中心挠度验证了数值模拟的有效性.研究表明.气囊织物受气流充胀后近似球形.中心处的薄膜应力最大,固定边界处的薄膜应力最小,且薄膜应力随气体压力的增大呈非线性增加;织物中心处径向薄膜应力与切向薄膜应力近似相等,固定边界处两者的差值最大,且切向薄膜应力减小为零.
