Judgment criteria and advantages of non-woven fabrics

Non-woven fabrics are mainly used in sofas, mattresses, clothing, etc. Its production principle is that polyester fiber, wool fiber and viscose fiber are combined with low-melting fiber after carding and laying. The product features of non-woven fabrics are white, soft, self-extinguishing and other features that meet the American testing standards. When we all operate and use non-woven fabrics, do you know what standards are there for this kind of non-woven fabrics?

Determination criteria for non-woven fabrics:
1. The maximum heat release efficiency cannot exceed 80 kilowatts;
2. The total heat release in the first 10 minutes cannot exceed 25 MJ;
3. The time for the concentration of CO (carbon monoxide) released by the sample to exceed 1000ppm should not exceed 5 minutes;
4. The smoke density cannot exceed 75%.

Product advantages of non-woven fabrics:
1. Pure white, soft hand feel, excellent elasticity, good moisture absorption and ventilation.
2. Natural fiber is used, and there is no dripping phenomenon. Has a permanent self-extinguishing effect
3. A dense carbonized layer is formed during combustion. The content of carbon monoxide and carbon dioxide is low, and only a small amount of non-toxic smoke is produced.
4. Stable acid and alkali resistance, non-toxic, and does not produce any chemical effects.

The criteria and advantages of non-woven fabrics are mainly manifested in the above areas. Now everyone should be clear about such non-woven fabrics. We need to use this non-woven fabric in a correct way.
