夹层式静电纺丝喷头及制备再生丝素纳米纤维纱的方法
摘要：
本发明公开了夹层式静电纺丝喷头及制备再生丝素纳米纤维纱的方法，夹层式静电纺丝喷头包括至少1个单喷头，所述单喷头又包括中空的喷管，所述喷管内同心嵌套有至少2个中空内喷管。制备再生丝素纳米纤维纱的方法为将凝固液与再生丝素纺丝液相间注入喷管及各内喷管并由所述喷口和内喷口喷出，在静电作用下拉伸细化形成再生丝素纳米纤维纱。本发明结构简单、操作方便、工艺流程短，且制备的再生丝素纳米纤维纱无需进行后处理并且具有不溶于水的特性。
摘要（英）：

The invention discloses a sandwich type electrostatic spinning spraying head and a method for manufacturing a regenerative fibroin nanofiber yarn. The sandwich type electrostatic spinning spraying head comprises at least one single spraying head which comprises a hollow spraying pipe, and at least two hollow inner spraying pipes are concentrically nested inside the spraying pipe. The method for manufacturing the regenerative fibroin nanofiber yarn includes the steps that coagulating liquid and regenerative fibroin spinning liquid are injected into the spraying pipe and the inner spraying pipes in an alternating mode and are sprayed out from a spraying opening and inner spraying openings, and under the electrostatic interaction, stretching and refining are conducted to form the regenerative fibroin nanofiber yarn. The sandwich type electrostatic spinning spraying head and the method for manufacturing the regenerative fibroin nanofiber yarn are simple in structure, convenient to operate and short in technological process, aftertreatment is needless in the regenerative fibroin nanofiber yarn, and the manufactured regenerative fibroin nanofiber yarn has the water-fast characteristic.
