Creating sunshade fabric is like dressing ordinary cloth in "protective armor," involving multiple meticulous processes to transform it into a special material that blocks sunlight, repels rain, and lasts long.
Workers first use polyester fiber or glass fiber to weave a base fabric, similar to making a fishing net. This mesh structure allows air to circulate while blocking most sunlight. To enhance sun protection, some fibers are mixed with sunscreen materials even before being spun into threads.
Brushing several layers of "sunscreen" onto the base fabric is a key step. These specially formulated coatings contain sun-blocking ingredients and are evenly applied to both sides of the fabric by machines. After each coating, the fabric is sent to a high-temperature oven to dry, ensuring the coating adheres firmly. Some factories also pre-treat the fabric surface with special technology for better adhesion.
Depending on the intended use, "superpowers" are added to the fabric. For example, a waterproof and breathable film may be laminated to keep out rain while preventing stuffiness on hot days; fire-retardant materials are incorporated for fire-resistant fabrics; and mildew-proof and anti-corrosion treatments are applied to fabrics used by the sea.
The finished fabric undergoes "tough tests": it is subjected to hundreds of hours in machines simulating wind and sun exposure to check for fading, deformation, or brittleness. Precision instruments are also used to measure the fabric’s strength, ensuring it remains intact after five to six years of use.
Today’s production processes are increasingly eco-friendly, using water-based coatings instead of chemical solvents and laser cutting to reduce waste. These improvements not only ensure the fabric’s durability but also minimize environmental impact. From rolls of ordinary chemical fiber to intelligent sunshade fabric that shields against elements, every step embodies the wisdom of modern manufacturing.
