Non-ironing finishing is a kind of chemical treatment, which often changes the excellent skin-friendly characteristics of pure cotton fabrics, leaving harmful chemicals (the environmentally-friendly reprocessing of harmful substances will offset some of the non-ironing effect, and the non-ironing effect will be lost after washing for 5-20 times at most), so high-end shirts sold in Europe and America are not ironed. High-grade fabrics should be washed gently and dried naturally (it is best not to spin dry). After drying, they can be worn with a little ironing, and they are very easy to iron. In fact, for high-end shirts, it is never a disadvantage to wrinkle easily. On the contrary, people who know how to wear can see the natural characteristics and expensive texture of fabrics at a glance, such as high-end shirts made of linen. Cotton+polyester blended fabric is easy to maintain, and the best cotton/polyester ratio is 7:3 ~ 6:4. This kind of fabric has the characteristics of wrinkle resistance and non-ironing of polyester fabric, and can be washed casually by machine. At the same time, it also has a good visual texture similar to pure cotton fabric. Can adapt to your needs to a certain extent, but want to keep a simple idea.
