Fabric type and water resistanceFeatured science projectScience project video

Conclusion

Our first hypothesis - that amongst the fabric types, polyester is the most water resistant – has been proven to be false. Our second hypothesis - that all fabrics demonstrate better water resistance after a layer of Scotch Guard is applied – has been prove correct.

Waterproof  fabrics can be made from natural or synthetic materials. Their ability to resist water droplets makes them suitable for use in manufacturing raincoats, tents and swimming attire  . They are normally given a coating of waterproofing chemicals like PVC, rubber or wax.

Also consider

The science fair project can also be repeated using different types of fabrics besides the ones that we tested.

Try to repeat the science project experiment by immersing the fabric in water and comparing the time taken for them to dry.
