Embodiment 1

[0066] Embodiment 1 viscose moisture regain measurement

[0067] The steps for measuring the moisture regain of viscose are as follows: ①Weigh the mass of the sample cylinder 4 without the sample to be 11.000g; connect and couple the sample cover 41 with the sample cup 42 side, and take the sample and put it in the sample cup 42; 2. the starter motor 56 drives the worm screw 55 and the screw mandrel 54 to rotate, and drives the third hollow tube 51 and the slide block 53 to move horizontally to the right limit position 94; the starter motor 26 drives the worm screw 25 and the screw mandrel 24 to rotate, Drive the Y-shaped bracket 21 and the slider 23 to move upward to the upper limit 91; place the sample container 4 on the Y-shaped bracket 21 on the lifting mechanism 2; ③ start the motor 56 to drive the worm 55 and the screw 54 to rotate, Drive the third hollow tube 51 and the slider 53 to move horizontally to the left, and push the sample container 4 to move horizontally to t...

Embodiment 2

[0070] Embodiment 2 Wool moisture regain measurement

[0071] According to the test method of embodiment 1, first weigh the quality G of the sample holder 4 without sample 0 It is 11.000g; weigh the sample container containing the sample 4 mass G 1 is 15.910g; adjust the suction flow area of ​​input mechanism 2 to 150cm 2 ;Start the induction cooker 15 through the driving system to heat and draw in the gas, and the temperature of the heating gas is 105°C±5°C; start the fan 13 and the fan 62 to adjust the gas flow rate to 0.1 m / s; ⑦After setting t1 to 360 seconds, weigh and install the test Sample container 4 quality G 2 It is 15.395g; ⑧ after setting for 120 seconds; repeat steps ⑦ and ⑧ until the weighing quality of the sample cylinder 4 is constant weight G 3 It is 15.400g. The quality-time curve corresponding to wool regain measurement is shown in the figure below. The correction coefficient a is -0.9961, and the moisture regain of the loose wool fiber aggregate can be...

Abstract

The invention relates to a device and a method for measuring the moisture regain of a loose fiber assembly. The device consists of an input mechanism, a lifting mechanism, a weighing mechanism, a sample barrel, a holding mechanism, an exhaust mechanism, a box body, a base and a stopper, wherein the sample barrel is arranged in the box body; the input mechanism is arranged on the left of the box body; the holding mechanism is arranged on the right of the box body; the lifting mechanism and the weighing mechanism are arranged below the box body; the weighing mechanism is arranged above the lifting mechanism; and the exhaust mechanism is arranged on the right of the holding mechanism and is connected with the holding mechanism. The method comprises: intensively blowing high-temperature hot air onto the loose fiber assembly at high flow rate to evaporate water; and measuring the mass of the dried loose fiber assembly and calculating the moisture regain. The invention can solve the problem of quick and effective measurement of the moisture regain of the loose fiber assembly.

Description

technical field [0001] The invention belongs to the technical field of moisture drying of fiber aggregates, in particular to a measuring device and method for moisture regain of loose fiber aggregates. Background technique [0002] Fiber aggregates are mostly stored and traded in loose form, and their moisture regain can significantly affect the quality, performance and shape of fibers, thereby affecting the quality of fibers; especially related to the interests of commercial transactions. Therefore, the study of moisture regain is extremely important, and it is also one of the important detection indicators. One of the methods for measuring the moisture regain of fiber aggregates is the indirect test method, that is, by establishing the relationship between the moisture regain and some indicators, such as electrical resistance (Wang Jianjun, Li Xiaofeng, Chen Rixin. Measuring the moisture content of textile fibers by AC impedance hygrometry .Sensor Technology, 2003, 22:65-...
