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感度复合织物提供基础数据。生产非织造布的方法有很多种。首先，结合本课题的研究目的，寻找最适合生产高感光性能非织造布的方法。水刺非织造布的特点是质地柔软、吸水性好、悬垂性高，因为该技术不需要热粘合或化学粘合工艺。因此，我们选择了水刺非织造布。接下来，我们尝试开发以水刺非织造布为主要原料的服装用真丝复合非织造布。真丝复合非织造布由四层组成，即两层真丝水刺非织造布为表层，一层网状非织造布为增强层，一层由普通纤维制成的吸水层。通过改变工艺参数，试制了几种真丝复合织物，研究了工艺参数对真丝复合织物结构和物理性能的影响。结果表明，工艺参数和复合元素影响真丝复合织物的孔径分布、物理性能和手感。特别是水射流二次压力和铺层结构对真丝复合织物的物理性能影响较大。最后，对真丝复合织物的耐洗性进行了评价。经洗涤试验，确认真丝复合织物可水洗20次左右。通过以上研究，得出了开发高感光真丝复合织物的基本思路。

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.
