How many kinds of production processes are there for PP high-strength yarn?
There are two process routes for PP high-strength yarn, namely two steps for spinning and drawing on two equipment and one step for spinning and drawing on the same equipment. One - step method has short spinning and FDY production line, and divided into horizontal and vertical two processes. Generally speaking, in one step method, compared with horizontal type, vertical has the advantages of high spinning and winding speed, can choose cheaper flat filament grade polypropylene as raw material, and horizontal type generally uses fiber grade polypropylene slice as raw material, the cost is higher. The two - step method has two kinds: horizontal cluster drawing and vertical single ingot drawing.
