growth rate of DTY machine in recent decade

According to the growth rate of DTY machine in recent decade, capacity expansion peak appeared in 2017-2018 and 2021. In 2017-2018, new DTY machine peaked as apparently increasing fabric mills integrated with DTY production. In 2019-2020, small DTY plants were less competitive compared with big plants with falling prosperity. New DTY machine mainly came from PFY plants and some fabric mills. Few small DTY plants expanded capacity. As a result, the growth rate of DTY machine fell back. In 2021, the increment of DTY machine hit historic new high as small DTY plants showed high investment enthusiasm and PFY producers further increased DTY production amid good profit in the fourth quarter of 2020
