Description
Technical field
The present invention relates to a kind of fabric test device, especially relate to a kind of Humid Permeability of Fabrics overall process proving installation.
Background technology
Humid Permeability of Fabrics is a complex dynamic process.At present, the method for testing about Humid Permeability of Fabrics mainly contains: vertical wicking method, fabric face drip method, water retention method, vertically absorb water method, sedimentation etc.Wherein vertical wicking method is to use the wet method of transmitting of wider a kind of test fabric.This method proving installation is as shown in Figure 1, fabric sample support 1 clamping fabric sample 2, and fabric sample 2 is about 300mm, the wide 30mm that is not less than.The upper end is by the clamping of folder appearance device, and the pretension device 5 of heavy 3g stretches the pretension of fabric sample in the lower end, then the fabric sample lower end is inserted in the water of water tank 4, immerses in the water when pretension device 5 upper ends, begins during the Humid Permeability of Fabrics tester.Then, when being defined in 30min,, read the wetted height of fabric, be called the Humid Permeability of Fabrics height, also claim the fabric measure wicking height with reference to gage 3; Also have when timing begins back 1min, 5min, 10min, 20min and 30min, read the fabric measure wicking height; For hydroscopicity fabric preferably,, when being increased in timing and beginning back 10s, 30s, read the fabric measure wicking height for the wet starting stage characteristic of transmitting of test fabric.According to the fabric measure wicking height that different time obtains, draw the Humid Permeability of Fabrics curve of measure wicking height-time, so that certain puts the wicking rate of tangent slope as this moment fabric on the curve.But there is following shortcoming in this method:
When (1) inserting in the water with the Humid Permeability of Fabrics tester, accomplish to keep strokes for two and have any problem by manually-operated fabric sample lower end;
(2) the fabric measure wicking height that is read by manual work reads in dynamically, and error is big, and is discrete big;
(3) inhale height owing to adopt manual work to read fabric core, less in the test data that regulation was obtained in the test duration, especially when the starting stage 10s of Humid Permeability of Fabrics, 30s, it is difficulty very that the manual read fetches data;
(4) inhale height owing to adopt manual work to read fabric core, when the polylith fabric was tested simultaneously, it was bigger to obtain the test data difficulty.
Zhuan Qinliang adopts image processing techniques, artificial the reading on the fabric core suction method highly of replacement breakthrough is arranged.But to of the dynamic change of fabric measure wicking height, adopt step motor control CCD cam movement, attempt fabric wicking image liquid forward position and shooting angle are consistent in vertical direction.Because the noncontinuity characteristic that the continuity of fabric wicking process and step motor are controlled, technically there is open defect and difficulty reaches re-set target.
The Jiang Xiao cloud is disclosed a kind of based on radial distortion modification method in the vertical wicking method image processing techniques, the CCD technology is obtained the Humid Permeability of Fabrics image continuously handle, and obtains the Humid Permeability of Fabrics curve of fabric measure wicking height-time.This Humid Permeability of Fabrics method of testing is simple, and data are reliable, but the CCD technology is obtained the checking that the device of Humid Permeability of Fabrics image is only applicable to said method continuously, also needs specific isoperibol to satisfy the environmental requirement of Humid Permeability of Fabrics performance test.
