Underwear fabric ~ Which is the best, modal, bamboo fiber or tencel?

Modal is the best underwear fabric. Bamboo fiber and Tencel are generally suitable for bed sheets, curtains, scarves, coats, tops and skirts.

Modal is a cellulose fiber, so it is a cellulose fiber like cotton and is a pure man-made fiber. The fiber is soft, smooth, bright in color, the fabric feels particularly smooth, the cloth surface is bright, and the drape is better than the existing cotton, polyester, and rayon. It has a silk-like luster and feel. It is a natural mercerized fabric. It has the strength and toughness of synthetic fibers, and its strength is higher than that of pure cotton and polyester cotton, which reduces breakage during processing. It has good shape and dimensional stability, making the fabric naturally wrinkle-resistant and non-ironing, making it more convenient and natural to wear.

The dry strength of Modal is close to the strength of polyester (35cn/tex), and the wet strength is slightly lower than cotton. It is soft and smooth, with a silky feel. The wet elongation is small, and the dry elongation of the fiber is between that of cotton. Compared with viscose, its wet elongation is similar to that of cotton, but smaller than that of viscose; its washing shrinkage rate is low, its good moisture absorption capacity is 50% higher than that of cotton, and it absorbs moisture very quickly. The dyeing characteristics of Modal fiber are that it absorbs pigments faster than combed cotton and carded cotton, and has a high absorption rate. The color is bright after dyeing and has good breathability.
