It is understood that at present, the maximum single-line capacity of large-scale polyester staple fiber complete sets of equipment in the world is 50,000 tons per year. Breaking this target has become the technical limit that all authoritative experts in various countries are concerned about and the targets of major manufacturers. China's annual output of 60,000 tons of short fiber domestic engineering technology and software package project is based on technology development. The production capacity of 200 tons per day is not only China's largest capacity for self-development, but also a leading position in the international community. The air blown tow cooling molding technology is the core of the annual production of 60,000 tons of short fiber production technology. The localization rate of a full set of technical equipment reaches 80%, which greatly reduces investment and brings valuable economic and social benefits.
China's chemical fiber industry was developed in the 1970s. During the period, the capacity of polyester staple fiber production lines redeveloped using imported equipment and domestic absorption technology reached an annual output of 15,000 tons. The annual production capacity of the production line introduced in the late 1980s and early 1990s was more than 30,000 tons. At present, China has become the largest producer of polyester fiber and chemical fiber in the world.
On July 7th, a project of polyester fiber staple technology --- an annual output of 60,000 tons of polyester staple fiber engineering technology development project, after six months of meticulous preparation and testing, a breakthrough in the Shanghai Petrochemical Corporation, The core technology of its research, the center blow-drying tow cooling molding technology has reached the desired goal. The success of this test indicates that China's polyester staple fiber large-scale production technology is in a leading position in the world.
