The difference between AB cotton and cotton
The difference between AB cotton and pure cotton, AB cotton is also called AB yarn, which is a composite yarn made by the siro spinning technique. Pure cotton should be said to be the preferred material for custom T-shirts, so pure cotton will definitely be T's answer.

What material is a HEPA filter?
HEPA filter: HEPA (High Efficiency Particulate Air Filter) filter, namely high-efficiency air purifier, is a multi-layer purification technology that can filter more than 99.97% of dust particles with a particle size exceeding 0.3 μm. HEPA filters have the characteristics of good filtering effect, good sealing performance and long service life, and are widely used in semiconductor manufacturing factories, liquid crystal electronics factories, modular clean rooms and other occasions requiring ultra-high cleanliness.
HEPA filter media is a kind of synthetic fiber material, which is made of high-performance, high-strength fibers. At the same time, advanced production technology is used to ensure its highly deepened dust holding capacity and ideal low-resistance performance. HEPA filter media compared with other filter materials, high-efficiency filter cotton has higher filtration efficiency and better performance. High-efficiency filter media has its own special structure, which can not only effectively accommodate more dust, but also effectively improve the efficiency of filtration.

The structural feature of the AB yarn is that the siro spinning is twisted in the same direction to make the yarn have a special structure. The surface of the siro spinning yarn is arranged neatly, the yarn structure is tight, the hairiness is small, and the pilling is good.
The siro spinning is fed into the spinning drafting zone by two strips with a certain spacing, which are respectively drawn and then twisted into yarn. To put it simply, two rovings are spun out of a spun yarn. Such yarns have the nature of strands and have less hairiness. They were originally used on woolen fabrics, and now there are many cotton spinning.
Compared with the strand fabric, the siro textile is soft and smooth. Siro spinning can be used for woven and knitted fabrics, and can also be used for high-density and high-density fabrics instead of strands.
