Examples
Embodiment 1
[0023] Example 1: The dehydration experiment of cotton, according to the characteristics of cotton: ① good hygroscopicity; ② wet strength is greater than dry strength, but overall firm and durable; ③ poor wrinkle resistance, large shrinkage. Therefore, the applicant chooses as figure 2 Shown pressure curve adopts device and method of the present invention, compares with traditional centrifugal dehydration, obtains following data:
[0024]
Embodiment 2
[0025] Embodiment 2: For the dehydration experiment of hemp, according to the characteristics of hemp: 1. good air permeability; 2. easy to wrinkle and poor drape; Therefore, the applicant chooses as image 3 Shown pressure curve adopts device and method of the present invention, compares with traditional centrifugal dehydration, obtains following data:
[0026]
Embodiment 3
[0027] Embodiment three: for the dehydration experiment of wool, according to the characteristics of wool: 1. protein fiber; 2. soft to the touch, more elastic than other natural fibers such as cotton, hemp, silk, etc., and good wrinkle resistance. Therefore, the applicant chooses as Figure 4 Shown pressure curve adopts device and method of the present invention, compares with traditional centrifugal dehydration, obtains following data:
[0028]
moisture content 1
Moisture content 2
Moisture content 3
Moisture content 4
The device of the present invention
44.5%
44.4%
44.6%
44.4%
centrifugal dehydrator
63.3%
62.2%
63.9%
62.8%
[0029] Based on the data of the above examples, the moisture content of the fabric after dehydration by the dehydration device and method of the present invention is less than 50%, and the dehydration effect is better than that of the centrifugal dehydrator.
