1. Waterproof finishing

Waterproof finishing - means that the fabric is difficult to wet, penetrate and absorb water. Through waterproof finishing, a continuous impermeable and water-insoluble film is coated on the surface of functional fabrics to prevent water from penetrating into the fabric and making it difficult for air and water vapor to pass through.

2. Water repellent finishing

Water-repellent finishing - refers to changing the properties of the fiber surface so that the hydrophilicity of the fiber surface becomes hydrophobic. However, there are still a large number of gaps between the fibers and yarns in functional fabrics. This is both breathable and not easily wetted by water. Water permeability will only occur when the water flow is quite large, similar to the water-repellent nature of lotus leaves.

Oil repellency is similar to water repellency, which means that the fabric is not easily soaked by oil and can prevent oil and oil stains from contaminating the fabric.

3. Easy to clean and decontaminate

Easy decontamination finishing - refers to the performance of functional fabrics that can easily shed dirt after finishing and prevent dirt from re-staining the fabric during washing. Compared with natural fibers, chemical fibers such as polyester have high strength, good cloth texture, bright colors, cheap prices, and easy processing. However, because polyester is a hydrophobic fiber, although fiber manufacturers continue to improve the shape and structure of the fiber, it is still difficult to achieve breathable, moisture-permeable, moisture-absorbing and quick-drying properties, and it has poor stain resistance, anti-fouling, and anti-static properties. It is easy to absorb dust when wearing, and the static electricity generated by friction makes the clothes close to the skin, giving people an uncomfortable feeling.

With the development of hydrophilic and easy-to-remove finishing agents, this kind of finishing can absorb the sweat discharged by the human body to the surface of clothing and evaporate quickly, keeping people dry and comfortable. It is also easy to remove and prevent stains. , anti-static and other properties, which can keep clothes as clean as new for a long time.
