Non woven fabrics are mainly used in sofas, mattresses, clothing, etc. Its production principle is to mix polyester fibers, wool fibers, viscose fibers, which are combed and laid into a mesh, with low melting point fibers. The product features of non-woven fabric are white, soft, and self extinguishing, which meet the testing standards of the United States. Do you know the standards for non-woven fabrics when we operate and use them? Today, the non-woven fabric manufacturer will introduce you.
Criteria for determining non-woven fabric
1. The maximum value of heat release efficiency Z cannot exceed 80 kilowatts;
2.The total heat release in the first 10 minutes should not exceed 25 megajoules.
3. The time for the concentration of CO (carbon monoxide) released from the sample to exceed 1000ppm cannot exceed 5 minutes;
4. The smoke density cannot exceed 75%.
Advantages of non-woven fabric products
1. Pure white, soft to the touch, excellent elasticity, good moisture absorption and breathability.
2. Using natural fibers without any dripping phenomenon. Has a long-lasting self extinguishing effect
A dense carbide layer is formed during combustion. Low levels of carbon monoxide and carbon dioxide can only produce a small amount of non-toxic smoke. 3. Stable acid and alkali resistance, non-toxic, and does not produce any chemical reactions.
Inspection standards for non-woven fabrics
Due to its practicality, non-woven fabrics have become increasingly widely used in agriculture and landscaping, and many non-woven fabric manufacturers have emerged as a result. So how should we make product choices in this environment? How to identify differences within the same product and how to purchase a product that meets one’s own requirements? This requires non-woven fabric manufacturers to inform you of the inspection standards for non-woven fabrics.
1. The actual color of non-woven fabric should have no significant color difference compared to the engineering sample color. If there is a color difference, it may be due to camera sensitivity or product quality issues.
2. On the appearance, the surface should have uniform color, good thickness and flatness, and no obvious defects such as glue spots, cloud spots, wrinkles, deformation, damage, etc.
3. Size specifications. The weight tolerance standard for non-woven fabric is+2.5% (per square meter), and the width tolerance is+0.5cm. Before purchasing, carefully read the product instructions, etc.
4. There should be no delamination or fuzzing on the upper structure of non-woven fabric. The tensile strength is generally 75g/100g230N, and the penetration power is generally 75g ≥ 1.01 and 100g>1.5J. 6. Packaging. Generally speaking, the packaging of non-woven fabric is 350-400Y/roll, packaged in transparent PP plastic bags, and requires observation of a complete and standardized factory qualification certificate.
When choosing non-woven fabric, analyze step by step whether the product is what you need based on these aspects. While ensuring that it meets your needs, you also need to ensure the quality of the product. The two pronged approach is the effective way in the selection process.
