increase of DTY machine and fabric manufacturing machine in recent 5 years

Comparing the increase of DTY machine and fabric manufacturing machine in recent 5 years, there are various types of fabric manufacturing machine, which is converted into the consumption of chemical fibers. Downstream capacity expanded intensively in 2017-2018. DTY machine and the consumption of chemical fibers among fabric manufacturing machine both extended higher. However, the profit of DTY and fabrics apparently declined in 2018 after new capacity rose. That meant falling growth rate in 2019 and the reduction of DTY machine was more apparent. In 2020 and 2021, the growth rate of chemical fiber consumption among fabric manufacturing machine was basically flat with that in 2019, while that of twisting machine gradually ascended, especially in 2021. The growth rate of DTY machine even outpaced that of chemical fiber consumption of fabric manufacturing machine mainly because DTY market witnessed obviously soaring profit since the fourth quarter of 2020
