What is the meaning of the micronaire value of the cotton clone?
What is the cotton clone value? What does micronaire mean? The intrinsic quality indicators of cotton fiber mainly include fiber length, fiber linear density, fiber strength and fiber maturity. In the identification of cotton grades, plus the micronaire value index, the quality dispute between buyers and sellers can be reduced, and the shoddy phenomenon can be effectively prevented.
Micronaire values ​​are also graded. Divided into three levels A, B, C, and B is the standard level. Class A ranges from 3.7 to 4.2, with good quality; Class B ranges from 3.5 to 3.6 and 4.3 to 4.9; Class C ranges from 3.4 and below to 5.0 and above, with poor quality. The specific measurement method is to use an air flow meter to measure the gas permeability of a constant weight cotton fiber after being pressed into a fixed volume, and is expressed by the scale value. The larger the value, the thicker the cotton fiber and the higher the maturity.
The micronaire value is also related to the quality of the yarn, but it cannot be generalized and is closely related to the thickness of the yarn. The high yarn has a high micronaire value, and the fiber has good yarn quality; the fine yarn, especially the ultrafine yarn, requires a relatively low micronaire value, and the yarn quality is good; the number of the fiber number is large, and the fiber strength is directly affected. The yarn is strong, the number of fibers in the fine unit section of the yarn number is small, and the number of fibers directly affects the yarn strength.

The tops with sleeves generally come in two styles: long sleeves and short sleeves, each suitable for different occasions. Short-sleeved tops are usually worn in the summer and provide a cool feeling when worn. Long-sleeved tops are typically worn in the spring or autumn, bringing a touch of coolness in the mild seasons. There are various styles of tops with sleeves available for women to choose from, including printed tops, solid-colored tops, and many others, catering to the different dressing needs of women.
