1. It has strong hygroscopicity and a large shrinkage rate of about 4~10%.
2, alkali resistance is not acid resistant. Cotton cloth is extremely unstable to inorganic acids, even if it is very dilute sulfuric acid, it will be destroyed, but the organic acid is weak and hardly destructive. Cotton cloth is more resistant to alkali. Generally, dilute alkali does not affect cotton at normal temperature, but the strength of cotton will decrease under strong alkali. The "silked" cotton cloth can be obtained by treating the cotton cloth with 20% caustic soda.

How to buy towels
(1) Look at the loops. The towel of good quality is used. The loops in each square of the front and back are long and long, rich and soft, and have the advantages of easy water absorption and storage; the poor quality of the towel is short and the loop is short.
(2) Look at the weight. A good quality towel is not only long and thick, but also heavy in weight.
(3) Look at softness and fastness. The main difference is whether the towel is a mature yarn product or a raw yarn product. The cooked yarn is soft and durable, has strong sweat absorption, and has a strong raw yarn feel and weak water absorption. If the hand feeling is not obvious, a little water can be taken, and the towel is dripped from a height of 30 cm. The water droplets are absorbed by the towel immediately, and the slow absorption is the raw yarn.
(4) Look at the quality of weaving. The towel is tiled or viewed from the sun to see if there are any weaving defects such as broken, broken weft, exposed bottom, napped, thin road, uneven loops, raw edges, curling, tooth edges and jump stitches. Finally, it depends on whether it has bleed. Appearance defects such as stains, skews, and blurring.
