Studies on composite Journal of the Textile Machinery Society of Japanfabric with high sensibility by using silk nonwovens

本研究的目的是为利用真丝非织造布生产高灵敏度复合织物提供基础数据。生产非织造布的方法有很多。首先，结合这个项目的目的，我们试图找到最适合的方法来生产具有高敏感性的非织造布。水刺非织造布的特点是质地柔软，吸水性能好，悬垂性高，因为该技术不需要热和化学键合工艺。因此，我们选择了水刺非织造布。其次，尝试开发以水刺非织造布为主的服装用丝绸复合非织造布。蚕丝复合非织造布由两层蚕丝水刺非织造布作为表层，一层网状非织造布作为增强层，一层由普通纤维制成的吸收网层组成。通过改变制造参数，制作了几种试制的复合织物，研究了制造参数对真丝复合织物结构和物理性能的影响。结果表明，制造参数和复合元素对真丝复合织物的孔径分布、物理性能和手感都有影响。特别是水射流的二次压力和铺设结构对真丝复合织物的物理性能影响较大。最后，我们尝试评价真丝复合织物的耐洗性。经过洗涤测试，我们确认真丝复合面料可以洗涤20次左右。综上所述，我们可以得出结论，我们获得了制作高灵敏度丝绸复合织物的基本指导。

The purpose of this study is to obtain the basic data to produce the composite fabrics with high sensibility by using silk nonwovens. There are many methods to produce nonwovens. Firstly, we tried to find the most suitable method to produce nonwovens with high sensibility properties along with the purpose of this project. The characteristics of spunlace nonwovens are soft texture, good absorbent property and high drapeability, because this technology does not need thermal or chemical bonding processes. Therefore, we made a choice the spunlace nonwovens. Next, we tried to develop the silk composite nonwovens for apparel uses composed from spunlace nonwovens mainly. The silk composite nonwovens is composed of four layers, such as two silk spunlace nonwovens as surface layer, one mesh nonwovens as reinforcement layer and one absorbent web layer made from ordinary fibers. We produced several composite fabrics built as trial by changing manufacturing parameters, and investigated how manufacturing parameters affect the structure and physical properties of silk composite fabrics. As a result, manufacturing parameters and composite elements influenced the pore size distribution, physical properties and handle of silk composite fabrics. Especially, the second pressure of water jet and laying structure influenced the physical properties of silk composite fabrics. Finally, we attempted to evaluate the washability of silk composite fabrics. As a result of washing tests, we confirmed that the silk composite fabrics can be washed about 20 times. From the facts described above, we may conclude that we obtained the basic instructions to make the silk composite fabrics with high sensibility properties.
