6. Suggestions

After the cloth sample with treatment results 1-3 was washed five times, the water repellency test showed that the cloth layer was almost soaked, and was given a rating of 0 at that time. After several repeated water repellency tests, the final rating was below 70. This situation occurs mainly due to insufficient penetration and low washing resistance. Penetrant should be appropriately supplemented during waterproofing treatment.
