Density and count can be said to be some professional problems in textile industry. Count is actually a way of yarn expression. Generally, the higher the count, the thinner the yarn will be, the thinner the woven fabric will be, and the fabric will feel relatively comfortable. 140 cotton four-piece suit should feel good, and the product already contains cotton, which has better breathability and comfort, but it will require high cotton quality and equipment technology in the cotton mill, so the quilt cover cost is relatively high.
There is no uniform standard for the number of cotton in a four-piece suit. Comfort is related to fabric and finishing process. Generally choose a four-piece suit with high count, the texture will be smoother and the price will be higher. Moreover, there are a large number of four-piece sets, and many raw materials are used, which will feel much thicker.
Finally, I want to say that the higher the count does not mean the better the product, but the fabric with high count costs more than the fabric with low count. I suggest you buy a four-piece product in combination with actual demand and economic situation.
