Abstract

The article tackles the problem of modern polymer materials and ultrasonic coupling application in footwear industry. During the study of ultrasonic connections of shoe parts it turned out that the low strength of the seams is an important problem. The purpose of the study is to increase the strength characteristics of the ultrasonic connections of summer shoe parts. Ethylene vinyl acetate, medium and low-density polyurethane, as well as belt tape that are used in summer shoes manufacture, were used as research objects. The study was carried out with the use of standard methods and techniques for determining the breaking load, and breaking load in shear. The equipment of the materials and technologies of textile industry department of the Kazan national research technological University was used for the research. The experiments results showed the influence of one of the main parameters of ultrasonic welding. The results of strength tests of the obtained samples allowed us to conclude that, in the area of sound waves impact of on the materials’ welding process used in shoe production, the optimal mode is the action of an ultrasonic wave for 3 seconds in the preliminary fastening. the characteristics of of A set of tests was carried out on the selected samples that made it possible to choose the best material for summer shoes production and the optimal mode of ultrasonic wave operation, which ensures high strength characteristics of the welded joint. The research results were used at the Taezhnik enterprise (Kazan) that specializes in the manufacture of products intended for use in various climatic conditions, including humid environment (clothes, backpacks, summer, demi-season, winter shoes, accessories for sports, outdoor activities and tourism).
超声波冲击时间对夏鞋接合件强度特性影响的研究
本文论述了现代高分子材料与超声耦合在鞋业中的应用问题。在鞋件超声连接研究中,发现接缝强度低是一个重要问题。研究的目的是提高夏季鞋件超声波连接的强度特性。以乙烯醋酸乙烯酯、中低密度聚氨酯、夏季制鞋用胶带为研究对象。研究采用标准的方法和技术来确定断裂荷载和剪切中的断裂荷载。采用喀山国立研究技术大学纺织工业系材料与工艺设备进行研究。实验结果表明了超声焊接的一个主要参数对焊接效果的影响。所得样品的强度测试结果使我们得出结论,在鞋类生产中使用的材料焊接过程中,在声波影响方面,最佳模式是在初步紧固中施加3秒的超声波作用。对所选样品进行了一组试验,为选择最佳的夏鞋生产材料和最佳的超声波操作方式提供了可能,从而保证了焊接接头的高强度特性。研究结果在Taezhnik企业(喀山)使用,该企业专门生产各种气候条件下使用的产品,包括潮湿环境(衣服,背包,夏季,半季节,冬季鞋,运动配件,户外活动和旅游)。
