Fiber and production method therefor, biodegradable polyester for fiber production and production method therefor, and nonwoven fabric |
| abstract |
A fiber according to the present disclosure has an average fiber diameter of at least 0.1 μm and no more than 6 μm and contains a biodegradable polyester having a weight average molecular weight of at least 1.0×104 and less than 1.0×105, and a melt viscosity of at least 1.0×100 Pa⋅s and no more than 2.0×102Pa⋅s at a temperature of 200°C and a shear rate of 0.1 s-1. The biodegradable polyester is suitable for use in fiber production applications. A fiber production method according to the present disclosure includes a step for spinning the biodegradable polyester by means of the melt blowing method or the melt electrospinning method. The present disclosure also provides a method for producing a biodegradable polyester for fiber production by means of hydrolysis or alcoholysis. |
