> The Polyester staple fiber machinery LHV801 and LHV802 Series were manufactured in early 1970s.LHV902 series were manufactured in middle 1980s.All the three series took nearly 1/2 Chinese market at that time.
> In middle 1990s,we began to research and develop 100t/d production line;and in 2002,this line was put into production.
> In 2003,we developed the whole set of 120t/d polyester staple fiber equipment.
> From 2005 to 2011,the 150t/d product line was put into batch production.
> In 2012,the 200t/d product line ran successfully.
> Recent max.capacity of one line:225t/d
> Up to now,we have manufactured more than 200 lines to manufacture various kinds of polyester staple fiber,in which more than 100 are with large capacity. We are the unique company that can produce 225t/d PSF product line.Till now,first-class fiber rate can reach over 98%and that of high-class fiber is over
95%.Because of the above achievement,the product lines are praised highly by users.

Comparison between the two processes
| Items | Small Capacity Line Process | Large Capacity Line Process |
| Capacity | 25t/d-70t/d | 75t/d-225t/d |
| Characteristics | It is suitable for producing differential products | For large capacity of high tenacity solid fiber production |
| Advantages | Flow is short,take small area | Large Capacity,fewer manpowercost |
| Disadvantages | Capacity is small | Take large area |
