摘要： Provided are a spinning apparatus capable of stably spinning fibers having a small fiber diameter with a high productivity, an apparatus comprising the same for manufacturing a nonwoven fabric, a process for manufacturing a nonwoven fabric using the nonwoven fabric manufacturing apparatus, and a nonwoven fabric produced by the process.The spinning apparatus of the present invention comprises one or more exits for extruding liquid, which are capable of extruding a spinning liquid, and one or more exits for ejecting gas, which extend linearly and are located upstream of each of the exits for extruding liquid and which are capable of ejecting a gas, wherein a shearing force by the gas and its accompanying airstream can be single-linearly exerted on the spinning liquid extruded. The apparatus of the present invention for manufacturing a nonwoven fabric comprises a fibers collection means as well as the spinning apparatus. The process of the present invention for manufacturing a nonwoven fabric is a process using the apparatus for manufacturing a nonwoven fabric. The nonwoven fabric of the present invention is a nonwoven fabric produced by the process.
