Let me tell you from the experience of a senior shirt fabric expert that pure cotton treated with liquid ammonia and moisture hinges can achieve anti-wrinkle and quick-drying effects. But is it expensive? It contains formaldehyde. The best thing is to use a CVC content of 80% cotton and 20% polyester, which is comfortable to wear, wrinkle-free and crisp. The polyester-cotton you are talking about is called polyester-cotton when the polyester content exceeds 50%. It is uncomfortable to wear and has poor breathability and comfort.
Nowadays, what many businesses call pure cotton is actually polyester-cotton cloth, because the two are indeed very similar, and polyester-cotton has a bright color and a tighter and finer fiber structure. Therefore, everyone must learn how to identify to avoid being fooled~~
Visually, polyester-cotton cloth has a brighter color than pure cotton cloth; if it is printed cloth, the color density contrast between the front and back of pure cotton cloth will be It is larger, and the colors of the front and back of the polyester-cotton fabric are closer.
In terms of hand feel, pure cotton fabric is soft but not smooth, while polyester cotton fabric feels a little slippery to the touch.
The combustion method is also the most intuitive method widely used by people in the industry. Pure cotton cloth ignites at a touch, the flame is yellow, and the burning smell is the same as burning paper. After burning, the edges are soft, leaving little gray-black flocculent ash; polyester cotton cloth will shrink and then melt when it is close to the flame. It emits thick black smoke and smells like low-quality aromatics. After burning, the edges become hard and the ashes are dark brown lumps, but they can be crushed.
