How to identify the quality of the gauze pad
How to identify the quality of the gauze pad?
Myth: The thicker the better
The gauze pad is woven from cotton yarn by air-jet / shuttle loom, and then degreased and bleached. After drying, it is cut and folded to the required size and thickness, and then packed. The thickness of the gauze and its layers and the thickness of the yarn are very different Big relationship.
gauze pad yarn index
1. Inch count (Ne)-at a constant moisture regain, a multiple of 840 yards in length for a pound of yarn, which means that a pound of yarn is exactly 840 yards long, which is 1 yarn and 1 pound of yarn The thread length is 21 × 840 yards long, and the fineness of the yarn is 21 counts, written as 21s. The imperial count is fixed weight, so the larger the count, the finer the yarn. The imperial count is not the legal yarn fineness index in China today, but it is still widely used in enterprises, especially the cotton textile industry.
2. Metric count (Nm)-under the definite moisture regain rate, a multiple of the length of a gram of yarn, which means that a gram of yarn is exactly 1 meter long, which is 1 (metric) yarn and 1 gram The yarn length is 200 meters long and the yarn fineness is 200 counts. Metric counts are also fixed weight, so the larger the count, the finer the yarn. It is used in the cotton and wool industries.
3, Tex (also known as "number") refers to the weight in grams of 1000 meters of yarn at given moisture regain. It is a unit of fixed length. The larger the weight, the thicker the yarn. , Commonly used to represent wool yarn.
4. Denier (D)-also known as "denier" or (denier: denier), refers to the weight in grams of 9000 meters of yarn or fiber at given moisture regain, such as 100D. It is also the same Units of fixed length. The larger the weight, the thicker the yarn or fiber. It is often used to indicate chemical fiber filaments and silk.
5. Count—One pound (453.5 grams) of cotton is spun into an 840-yard length cotton yarn; it is spun into 8400 yards, which is 10 yarns. The larger the number of yarns, the finer the yarn and the better the quality of cotton Well, there are 21, 32, 38, 42, 46, 60S / 2 and so on. S / 2 is a double-stranded mark. The higher the number, the better the quality.
