About fabric knowledge
Many people ask why the price difference of the same 95% Cotton + 5% spandex is so big, while others say it is synthetic.
Here's a simple Science Popularization:
From spinning to finished products, there are many processing methods, which can make the fabric produce different sensory effects. For example, cotton yarn can be made into 21s, 26S, 32S, 40s, 50s… For example, 40s can be made into ring spinning, carding, combing, compact spinning, siro spinning and compact Siro spinning
Similarly, in the weaving, dyeing and finishing, singeing and other processes, different processes can be used to make the fabric present different sensory effects.
No matter how many processes there are, the fabric content is determined during spinning and cannot be changed. The yarn is spun in the proportion of (95% Cotton + 5% spandex) / ton, and the finished product is 95% Cotton + 5% spandex。
Why not use 100% cotton
The biggest disadvantage of 100% cotton is poor resilience and easy to deform. After washing for several times, it will become wrinkled and hard. Underwear is close to the body. It needs to be soft and comfortable. The 100% cotton fabric made by the same cotton yarn process is cheaper than adding spandex.
