Fabric water repellent treatment and test method

There are many examples of textile waterproofing in everyday life, such as umbrellas and diving suits.

How are textile fabrics waterproof?
The commonly used fabric waterproofing treatment is divided into water-repellent treatment, hydrostatic pressure-resistant treatment and moisture-permeable waterproof treatment.
qinsun has associated waterproof testing equipment.

1. Water-repellent treatment
After the fabric has undergone a water-repellent treatment, the surface tension changes and the fabric changes from hydrophilic to hydrophobic. The water drops that drip on the fabric can drip just like on the lotus leaf, roll but not get wet.

The spray testing machine can carry out a spray test to measure the resistance of fabric to water surface wetting. Syringe quantificationf distilled water on the sample with a bracket (45 degree angle, less than 150 mm) hard nozzle. Then use the standard map to compare and evaluate the surface of the sample.

2. Hydrostatic treatment
The surface of the fabric is coated with an impermeable continuous film that blocks the voids in the fabric and prevents the passage of water droplets. This method is also known as coating finishing.

Digital hydrostatic head tester is used to test the waterproof performance of fabrics, such as through waterproofing work Canvas, coated cloth, hooded cloth, tarpaulin, tarpaulin, geotextile.

3. Moisture-permeable and waterproof treatment
Garments are usually worn without
