ISO Certification Textile Testing Machine , Textile Lab Equipment For Clothing
Product introduction
Textile Testing Machine mainly applies to the pilling & abrasion
resistance test of textile the similar fabric.Testing the samples
as per the standard, test can be classified as dry test and wet
test. And test the samples Lissajous-oriented for the regulated
times, then observe the difference between it and the original
samples and decide the grade of scrubbing resistance.

Principle
A standard aerosol of NaC1 particles is generated by an aerosol
generator, and enters the test room to maintain a relatively stable
state. The test subject wears the test protective clothing to
perform a test action according to a predetermined plan in the test
room. The aerosol concentration of NaC1 particles in the protective
clothing under test was measured at the sampling point, and the
overall protective performance of the protective clothing against
particulates was evaluated by the following indicators:
——Single inward leak rate at each sampling location Lijm
——Total inward leakage rate of each protective clothing tested LS
——Total inward leakage rate of each measured object LH
——Total inward leakage rate for each test action le
——Total inward leakage rate at each sampling location LP
——Average total inward leakage rate L

Correlation traceability index
1,Particle aerosol generator;
The air volume is not less than 100L/min, and the concentration of
NaC1 aerosol (10±1)mg/m³ is ≤ ±10% in the effective space of the
test chamber.The aerodynamic particle size distribution of
particles should be (0.02-2)μm, and the mass median diameter is
about 0.6μm.
2,Particulate detector;
Two detectors were used to detect the concentration of NaC1 aerosol
particles in the test room and the protective clothing
respectively.The dynamic range is (0.001-200)mg/m³, the precision
is ±1%, and the detector's response time is ≤ 500ms.
3,Horizontal pedal drive test-bed;
1pc,the operation speed is (5±0.5)km/h , install inside of the test
room.
4,Sampling pump and air line;
2pcs are used to collect NaC1 aerosol in the test room and the
protective clothing.Flow range (0.05-4) L/min, flow fluctuation
<± 0.2L /min.It can ensure that the sampling probe can sample at
a flow rate of (2±0.5) L/min inside the protective clothing under
test.
In order to ensure that the reduced pressure generated by sampling
in the protective clothing under test does not cause an additional
inward leakage rate, it should be delivered in the sampled
colleagues at a rate of (2±0.5) L/min to the protective clothing
under test.Clean air can be fed to one of the two other sampling
probes in the sampling interval according to the sampling sequence
of the schematic.
5,Sampling probe;
There were 4 sampling probes, one of which was used to detect the
concentration of NaC1 aerosol particles in the environment of the
test room, and the other 3 were used to measure the concentration
of NaC1 aerosol particles in the protective clothing under test.The
sampling probe is connected to a transparent plastic tube with an
inner.
