Embodiment 1
[0032] Utilizing recycled polyester bottles to manufacture polyester staple fibers with specifications of 1.56dtex×38mm mainly includes the following steps:
[0033] 1) Sorting and sorting the purchased bottles of polyester components, and sorting out the bottles mainly for different colors and some non-polyester components such as miscellaneous bottles, sawdust, sand and stones before entering the machine. Bottles of different colors are stored separately, and used as raw materials for different primary color varieties; through the conveyor belt machine, they enter the labeling machine equipment for label removal and preliminary water cleaning, and then enter the crusher table through the conveyor belt device to be crushed into upper-machine materials and molding materials. After the size of the sheet is square and about 14mm×14mm, it will be cleaned later.
[0034] 2) The broken bottle flakes enter the grinding machine with water spray through the feeder equipment for fricti...
