3.1 Hydrostatic Test Method
The size of the fabric after finishing by water repellent can withstand hydrostatic pressure of water to reflect the time to penetrate the fabric suffered resistance. In the present
Under standard conditions, the sample side of the fabric to withstand a gradual increase of pressure until the other side of the fabric there are three water penetration so far, remember
Pressure values recorded at this time, that is water repellent waterproof force. The resulting hydrostatic values are expressed in kPa.
3.2 Spray test
On the sample surface tension of water to spray, so to produce a wetted pattern. The size of the pattern depends on the waterproofing agent waterproof large small. The wet mode standard spray test level chart compares to assess the force of its water level.
4 Reagents or materials
4.1 Test fabric material
4.1.1 cotton poplin (65/35)
602/602 double strand, a density of 12070;
4.1.2 khaki cotton (65/35)
452/21 double strand single line density of 13,570.
Note. according to the specific need to use other fabrics.
4.2 Preparation of the sample water repellent
Preparation of water repellent padding solution. Weigh waterproofing agent several grams (weighing accuracy 0.1g). Depending on the formulation and preparation of various types of water repellent
Steps. Should Extemporaneous.
Padding 4.3 waterproofing agent
Process. Second Baptist Second rolling (water repellent formulated liquid) -> drying -> intermediate baking.
Mangle. general should be controlled at (60 ± 5)%.
Intermediate drying temperature and time. Usually about 100 °C, 1min.
Baking temperature and time. depending on the performance of waterproofing agent and selected.
4.4 Sampling and Sample Size
4.4.1 Static pressure test
The specimen should be minimal touch to avoid folding force, without any way of processing (such as iron). In big
Take place in different parts of the sample 5. Do not have a deep crease sampling.
Sample Size. 20cm × 20cm square.
4.4.2 Spray test
The specimen should be minimal touch to avoid folding force, without any way of processing (such as iron). From the big test […]
