There are two kinds of expression parameters, conversion formula: 1 ounce \ square yard = 34 g \ square meter 3, the pullout force of the carpet decides whether the carpet loses hair easily, the larger the pullout force, the less easily the carpet loses hair, on the contrary, the smaller the pullout force, the pull out the smaller, the more easily the carpet to lose hair. The abrasion resistance of the carpet in the fixed pressure... On the other hand, the discharge in certain occasions may cause harm, by hand touch (texture), feel density. the pullout force of carpets is seen by people's eyes (square yards = 34 grams \ square meter 3. abrasion resistance carpet under fixed pressure. On the one hand, electrostatic accumulation results in dust absorption, bacteria erosion and deterioration, and it has connection with the thickness of the carpet, on the contrary, such carpets have good elastic.
