Description
Technical field
The invention belongs to the testing fields of fabric property, and in particular to a kind of fabric moisture tester and its measurement side
Method.
Background technique
Comfortable features of clothing is exactly the characteristic that human body feels comfortable when clothes are worn in simple terms, but it is related to many fields,
Psychology, physiology, physics, materialogy and anthroposociology etc..Wherein, Fabric Wetting Characteristics, that is, water absorption of fabrics amount,
Rate of water absorption is the important parameter for reflecting comfort of fabric, and the method for testing and studying in the prior art the performance indicator is as follows:
A kind of test method of moisture absorption performance of wool fabric as disclosed in Chinese patent literature CN102519844A, step is such as
Under: step 1: take two pieces of sample of 10cm × 10cm to be used as test sample on the fabric sample that 40cm leads to width；Step 2: will
Sample is placed in washing appearance device, and 300ml tetrachloro-ethylene is added as dry cleaning agent, is put into dry-cleaning instrument and dry-cleans 30 minutes after sealing
After take out, then wash repeatedly twice；Step 3: the sample after dry-cleaning being flat on desktop, is laid flat naturally, dropper (precision
0.1ml) apart from 5 ± 0.5cm of cloth cover, instill 3ml distilled water to cloth cover, press stopwatch (precision >=0.1 second), record drip when
Between；Step 4: water droplet penetrates into inside fabric on cloth cover, will form water stain circle printing on cloth cover, after dripping 10 seconds, measurement circle
The minimum and maximum diameter of print, is accurate to 0.1mm, test result is the average value of minimum and maximum diameter, and the revision of the convention arrives

Diameter easily facilitates the fluid change observed in the liquid-adding tube 1.
Further, the internal diameter of the air inlet pipe 3 is 0.5-1cm, and in the present embodiment, the internal diameter of the air inlet pipe 3 is
0.5cm easily facilitates the liquid exudation controlled in the liquid-adding tube 1, on the one hand keeps away by controlling the internal diameter of the air inlet pipe 3
Exempt from that internal diameter is excessive, cause the liquid velocity oozed out in the sepage disk 5 too fast, is difficult to control, on the other hand avoids internal diameter too small,
Cause the liquid velocity oozed out in the sepage disk 5 excessively slow, time-consuming for detection.
Further, the aperture of the liquid-leadage hole 8 is 0.1-0.3cm, in the present embodiment, the aperture of the liquid-leadage hole 8
The liquid exudation controlled in the liquid-adding tube 1 is easily facilitated, on the one hand by controlling the aperture of the liquid-leadage hole 8 for 0.1cm
It avoids aperture excessive, causes the liquid velocity oozed out in the liquid-leadage hole 8 too fast, it is too big with perspiring situation difference, it cannot
Better simulated human sweat situation, on the other hand avoids aperture too small, leads to the liquid velocity mistake oozed out in the liquid-leadage hole 8
Slowly, time-consuming for detection.
Further, 4 internal diameter of outlet tube is 1-2cm, and in the present embodiment, 4 internal diameter of outlet tube is 1cm, into
The liquid that one step controls in the liquid-adding tube 1 flows in the sepage disk 5.
Further, the liquid-penetrating area 7 is round or rectangular, and the size of the liquid-penetrating area 7 is 30-100cm2,
