14、ganic cotton. But the percentage of organic cotton in the global market is currently still small (about 25%), due partly to the higher production costs (due to lower yields and increased cultivation work) and the fact that it is not possible to get higher market prices for organic cotton garments.

22、se, they remain creased for the duration of wear. The two primary causes of wrinkling in fabrics are water moisture and heat. There are ways to reduce it from wrinkling.

32、, natural color or color-grown fabrics are the best choice for people. man： I dont think so. I think material is much more important than color when associated with health. Clothes made of natural fibers are usually healthier to wear, but not all synthetic fabrics go straight into the “no” column, s

33、ome of them are even more skin-friendly than others. woman： So you mean one could not take it for granted that all natural fibers are better than synthetic fibers. man： Yes.

34、 silk and many synthetics are not. woman： There are also some people who think that clothing style has a big effect on health. man： I quite agree with it.
