A coated fabric is a fabric that increases its performance and function by coating a special material on the surface of the fabric. The quality of coated fabrics mainly depends on the type and quality of coating materials, the technical level of coating process and the quality of the fabric itself. Here are some ways to judge the quality of coated fabrics:
1. Touch check: Touch the surface of the fabric to see if it is soft and smooth and comfortable to feel. If the surface of the fabric has a rough feeling, it may indicate that the quality of the coating is not good, which will affect the comfort and service life of the fabric.
2. Color check: Observe whether the color of the fabric is uniform, whether there are spots or color differences, and whether it is consistent with the specified color. The color is uniform and consistent with the specified color, indicating that the dyeing process of the coated fabric is good, the color fastness is high, and the color is durable.
3. Strength test: Stretch the coated fabric to see its tensile strength. The strength of the coated fabric refers to the maximum force that the fabric can withstand when it is subjected to tension, which is related to the strength of the coated material and the bonding process. High strength coated fabrics have long service life and good wear resistance.
4. Water resistance check: Soak the coated fabric in water to check whether the surface is permeated with water. A good coated fabric should have good waterproof performance, the surface is not easy to permeate water, and can effectively prevent rain penetration.
5. Anti-fouling performance inspection: the coated fabric should have a certain anti-fouling performance, which can prevent stains from entering the fabric and is easy to clean. Some common stains can be applied to the fabric to see if it is easy to clean and remove stains.
6. Heat resistance check: Place the coated fabric in a high temperature environment to check whether it is melted, deformed or fuzzed. High-quality coated fabrics should have high heat resistance and can remain stable at high temperatures.
7. Air permeability inspection: By observing the air permeability of the coated fabric to judge its quality. The coated fabric with good air permeability can maintain comfort and will not feel damp and breathable because of long-term wear.
8. Environmental protection inspection: the coated fabric should meet the requirements of environmental protection and does not contain substances harmful to the human body. You can judge the environmental performance of the product by viewing the environmental protection mark, test report, etc.
9. Durability evaluation: Determine the durability of coated fabrics through service life tests and tests simulating real conditions of use. Durability Good coated fabrics can maintain their function and appearance for a long time.
10. Material testing: The coating fabric can be sent to a professional laboratory for material testing to detect its physical properties, chemical composition, etc. This allows for a more accurate assessment of the quality and performance of the coated fabric.
To sum up, the methods for judging the quality of coated fabrics include touch inspection, color inspection, strength test, water resistance inspection, anti-fouling performance inspection, heat resistance inspection, air permeability inspection, environmental protection inspection, durability assessment and material testing. By comprehensively evaluating the performance of these aspects, the quality of coated fabrics can be more comprehensively understood.
