Furthermore, the monofilament fineness of the superfine cellulose is 0.3 dtex-1.0 dtex.

Experiments show that the sampling time of the fiber bundle 201 provided by the embodiment is within 10s, and is greatly reduced compared with the original sampling time of 3 min. But also the tow 201 that this embodiment provided can plug the setting, and the sample is convenient and the sample volume is few.

Referring to fig. 1 and fig. 3, in the embodiment, a first limiting boss 105 and a second limiting boss 108 are fixedly disposed in the housing slot 104, wherein the second limiting boss 108 is located on a side of the first limiting boss 105 away from the test paper 3, and the second limiting boss 108 is provided with a plate passing gap 1081.

The exterior of the sampler 2 is provided with a clamping plate 203 which can pass through the plate passing notch 1081 and enter the limiting gap between the first limiting boss 105 and the second limiting boss 108.
