Is dacron cloth waterproof?
The real waterproof finishing is not PU coating, but the use of hydrophobic finishing agent to deal with fabric, can improve waterproof, looking still or dacron cloth, not artificial leather! Advanced waterproof treatment, but also breathable. For example, the United States world famous brand, Gore Tex's fabric, widely used in outdoor products, such as assault clothes, assault pants, climbing shoes, etc., in ensuring the permeability of the premise, with waterproof performance.
The polyester fabric itself is waterproof, but if used for waterproofing, a PU coating is required because the PU coating blocks the fabric's pores.
Dacron fabric itself is not waterproof! Polyester fiber is hydrophobic, but not equal to polyester cloth will be waterproof, but not as absorbent as cotton cloth, infiltration.PU coating is a waterproof way, but this result, polyester cloth is no longer cloth, but artificial leather!
Dacron fabric is not waterproof. Polyester properties:1) high strength, impact resistance is 4 times higher than nylon, 20 times higher than viscose fiber.2) good elasticity. The elasticity close to wool, when stretched 5% ~ 6%, can almost completely recover. Wrinkle resistance over other fibers, that is, fabric does not wrinkle, good dimensional stability. The elasticity is 2~3 times higher than that of nylon.3) good heat resistance.4) good water absorption.5) good wear resistance. Wear resistance is second only to nylon, which is the most wearable, better than other natural and synthetic fibers.6) good light resistance. Light resistance is second only to acrylic fiber.7) corrosion resistance. Resistance to bleaching agent, oxidizing agent, hydrocarbons, ketones, petroleum products and inorganic acid. Resistant to dilute alkali, not afraid of mildew, but hot alkali can make it decomposition.8) poor staining. Polyester fiber based on its performance can be divided into standard type (HT high strength and low extension Series), low shrinkage (LS medium strength, low shrinkage Series), dimensional stability (HMLS high modulus, low shrinkage series).
