How to identify the quality of gauze block? Myth: the thicker the better The gauze block is woven from cotton yarn on air jet / shuttle loom, degreased and bleached, dried, cut and folded into required size and thickness, and then packaged. The thickness of gauze has a great relationship with the number of layers and the thickness of yarn. Yarn index of gauze block 1. British yarn count (NE) - under the constant moisture regain, the multiple of 840 yards of 1-pound yarn length, that is to say, 1-pound yarn is 840 yards long, which is a yarn, the length of 1-pound yarn is 21 × 840 yards, and the yarn fineness is 21, which is written as 21s. The British count is fixed weight system, so the larger the

What is the difference between medical masks and ordinary masks? 1. The number of layers is different Medical mask is composed of 2113 mask body and tension belt, 5261 of which the mask body is divided into 4102 inner, middle and outer layers.

The protective effect is different The ordinary mask is used to filter the air entering the mouth and nose, so as to prevent harmful gases, odors and droplets from entering and leaving the wearer's mouth and nose. Medical mask, comfortable, tasteless, without glass fiber, has no irritation to the skin and is waterproof.
