The melt direct spinning becomes the most advanced leading process in the world

due to the features of its large capacity

low energy consumption

high efficiency and low cost. However

the melt direct spinning is facing the homogeneous structural problem of the equipment

techniques

products and market. In order to unify the large scale

low cost

high added value and high quality in the fiber products

it eager to develop the production equipment and techniques of low energy

flexibility

automation

and informatization. Combining the polyester fiber formation and engineering technologies at home and abroad

the newest research progress is introduced through the flexible preparation of the melt direct spinning polyester fiber

melt transportation and online addition

the spinning box design

engineering simulation model

energy saving and intelligent management. It suggests that large capacity

low cost

melt direct spinning

flexibility

multi-varieties are the development direction for polyester enterprise in China. At last

the prospect of is discussed in this paper. Based on the theory of polymerization and spinning

engineering technologies on large capacity polymerization

online addition

compact spinning

energy conservation and intelligent logistics are becoming the future trends of polyester industry in China.
