The yarn mercerizing equipment is mainly skein mercerizing machine, which is completed by soaking alkali, alkali extrusion, roller stretching and water washing. It is famous for its Italian company Jeaggle. The fabric mercerizing machine generally uses the roller to repeatedly soak the alkali and then through the needle plate. Stretched, finally washed structure, more famous manufacturers are Benninger of Switzerland, Dornier of Germany. However, the two types of mercerizing machines are not suitable for the mercerization of cellulose fibers, mainly because the cellulose fibers are in a state of no tension after being discharged from the machine, and when the mercerizing alkali is absorbed, a large amount of alkali liquid is absorbed to cause excessive swelling and dissolution, so the market has been There is no mature cellulose fiber rayon equipment, which restricts the development of cellulose fiber such as cotton fiber.
