This depends on what kind of products you are targeting and the style positioning of the products. Each ingredient has its own characteristics, self-feeling:

Cotton: The style of cotton clothes is simple and casual.

Hemp: It's a national style, and it feels simple, but the follow-up care is more troublesome, wrinkles are easy to appear, and it must be washed by hand.

Silk: Silk products will give people a high-grade feeling and the price is relatively high. Silk and cotton can also be considered.

Chemical fiber: chemical fiber products have changed the most, including coats and underwear, and knitting and weaving are also very extensive. It doesn't mean that what is natural must be the best.

There is also an adhesive product, which belongs to recycled fiber and has good drape and soft hand feeling. Suitable for summer clothes.

I hope it helps you.
