Textiles –
Testing and evaluation for anti-mosquitoes properties
1 Scope
This standard specifies the method of using repellent method AND forced
contact method to measure the textile’s anti-mosquitoes properties, AND
provides the anti-mosquitoes properties evaluation.
This standard applies to the woven fabrics, knitted fabrics, non-woven fabrics
and other textiles.
2 Normative references
The following documents are essential to the application of this document. For
the dated documents, only the versions with the dates indicated are applicable
to this document; for the undated documents, only the latest version (including
all the amendments) are applicable to this Standard.
GB/T 12490-2007 Textiles – Tests for color fastness – Color fastness to
domestic and commercial laundering
3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Anti-mosquitoes properties
It refers to the product features of knocking down, killing, and repelling
mosquitoes, etc.
3.2
Control fabric
It refers to the fabrics used to compare the anti-mosquitoes properties with
the samples to be tested.
4 Safety precautions
When using this method, it is required to contact with mosquitoes, and has the
mosquito breeding conditions, so it shall, under the specified test conditions,
ARRANGE the trained personnel to conduct test.
5 Principles
Repellent method. PLACE the mosquitoes which has certain offensive power
into the space containing the sample, which is attached to the human body OR
blood providing device;
6 Equipment and materials
6.1 Constant temperature and humidity laboratory
It can maintain a certain test temperature and relative humidity; the
temperature accuracy is ± 1 °C AND the relative humidity accuracy is ± 10%.
6.3 Repellent tester
6.3.1 The repellent tester is rectangular, 18 cm (length) x 5cm (width) x 4 cm
(height); its top is fabricated by the gauze the mesh of which is 20 mesh ± 10
mesh; whilst its side surface, end plate, and bottom surface are fabricated by
transparent materials; REFER to Figure 2.
Figure 2 Repellent tester
6.5 Forced contactor
Forced contactor complying with GB/T 13917.1-2009.it is used to knock down
AND kill test.
6.6 Other
6.6.1 Mosquito suction tube.
6.6.2 Commonly used laboratory equipment such as measuring cylinder AND
flask, etc.
6.6.3 Stopwatch, counter.
6.6.4 Scissors.
6.6.5 5% sucrose solution.
7 Test mosquitoes
7.1 Mosquito species
Aedes albopictus, the female adult mosquito which is 4 d ~ 7 d after
emergence AND does not suck blood;
7.2 Indicated information
The mosquitoes used for test purposes shall be indicated of the following
information.
8 Sample preparation
8.1 Sample size and quantity
8.1.1 Repellent tester method
SELECT representative samples from each sample; CUT a 4 cm x 4 cm
square as a sample. Respectively TAKE 8 anti-mosquitoes fabric samples to
be tested AND 8 control fabrics.
8.2 Sample pretreatment
After placing the sample at 26 °C ± 1 °C for 10 min, CONDUCT test.
8.3 Treatment of anti-mosquito effect washability sample
If evaluating the fabric’s anti-mosquito washable performance, WASH the
sample to be tested in accordance with the sample conditions A1M of GB/T
12490-2007;
9 Test conditions
Temperature 26 °C ± 1 °C; relative humidity 65% ± 10%.
10 Test procedures
10.1 Repellent method
10.1.1 Repellent tester method
10.1.2 Blood-sucking insect feeding device method
In the 2 blood feeding boxes of the blood-sucking insects feeding device (6.4),
respectively ADD 10 mL of blood; USE artificial membrane to seal the blood;
respectively COVER the sample to be tested AND the control fabric over the
artificial membrane of the blood feeding box.
10.2 Forced contact method
USE the forced contactor to conduct test in accordance with the steps as
specified in 4.3.3.1 of GB/T 13917.1-2009.The test mosquitoes are Culex
pipiens pallens, and USE the sample to substitute the reagent contact surface.
11 Result calculation and evaluation
11.1 Result calculation
Based on the selected test, USE the equation (1) to calculate the sample’s
repellent ratio against mosquitoes; USE the equation (2) and (3) to calculate
the sample’s knock-down ratio and kill ratio against mosquitoes; KEEP one
decimal place.
