I. What is waterproof, oil-proof and dirt-proof fabric?
Waterproof, oil-proof and dirt-proof fabric (referred to as three-proof fabric) is a composite functional fabric treated with special technology. Its core principle is to form a nanometer-level protective layer on the surface of the fibre, so that the liquid will present a ball effect when it comes into contact, instead of seeping into the fibre. Commonly used substrates include polyester fibre, nylon and other synthetic fibres, and fluoro-containing compounds and other auxiliaries are added through immersion or coating processes to achieve protection. This kind of fabric can not only block liquid infiltration, but also reduce stain adhesion, which is more convenient to take care of at ordinary times.
II. Frequently asked questions about waterproof, oil-proof and dirt-proof fabrics
Question 1: Is this fabric permanently waterproof and dirt-proof?
Answer: It is not permanent protection. Its protective effect is mainly achieved by surface coating. Long-term friction, washing, exposure or high-temperature ironing will cause the surface auxiliary to slowly lose, the coating will wear out, and the protective performance will gradually weaken. This is a normal phenomenon, not a problem of fabric quality. Good quality three-proof fabric, as long as you pay attention to maintenance at ordinary times, you can still maintain the basic protective effect for a long time.
Question 2: Does the fabric need to be cleaned completely if it is stained?
Answer: It is not exempt from cleaning. This kind of fabric can resist liquid oil, water and dust stains, but long-term adhesion of stubborn stains, viscous dirt and pigment stains will cover the fabric protective layer, block the fibre pores, and destroy the performance over time. Slight stains can be wiped directly, but stubborn stains still need to be cleaned regularly.
Question 3: Is this fabric harmful to human skin?
Answer: Compliance high-quality waterproof, oil-proof and dirt-proof fabric is safe and harmless. Regular manufacturers use environmentally friendly fluorine-free three-proof auxiliary agents. After passing the safety test, there is no odour, no harmful substance residue, and it is skin-friendly and safe.
As the mainstream choice of functional fabrics, waterproof, oil-proof and dirt-proof fabrics continue to empower many industries such as clothing and home textiles to upgrade with the core advantages of practicality, durability and comfort. Correctly recognise the performance of the fabric and avoid misunderstandings in use, which can maximise the protective value of the fabric and extend the service life of the product.
