1. Structural composition
Polypropylene monofilament rope: It is a rope made of a single polypropylene fiber. This type of fiber is thicker and has a relatively larger diameter per filament. It is usually made by extruding, stretching, or other processes from polypropylene resin to form a single continuous filament, which is then twisted or woven into a rope.
Polypropylene multifilament rope: composed of multiple thin polypropylene monofilament fibers. These monofilaments are first made through spinning technology, and then multiple monofilaments are combined together by twisting or weaving to form ropes. The diameter of a single filament in multifilament is much smaller than that of a single filament rope.
2. Physical properties
strength
Polypropylene monofilament rope: The monofilament is relatively thick, and at the same diameter, the strength of the monofilament rope mainly depends on this monofilament. Its strength is generally not as high as that of multi filament ropes, because if there are local defects inside the single filament, it is easy to become a stress concentration point, leading to a decrease in overall strength.
Polypropylene multifilament rope: As it is composed of multiple single filaments, when subjected to external force, the force will be dispersed onto multiple single filaments. Even if a few of the monofilaments have defects or fractures, the other monofilaments can still withstand a certain load, so the overall strength is relatively high.
flexibility
Polypropylene monofilament rope: Poor flexibility, relatively stiff. This is because the monofilament is relatively thick, and the fibers inside the monofilament are not easily able to slide against each other to adapt to the bending shape when bent.
Polypropylene multifilament rope: good flexibility. Multiple single fibers in multifilament can slide and displace with each other, and can better adapt to shape changes when bent, so the rope is relatively soft and easy to bend and knot.
3. Appearance and Touch
Polypropylene monofilament rope: It has a relatively smooth appearance and a relatively simple surface texture because there is only one monofilament. The touch is relatively hard and may have some plastic texture, similar to thicker plastic threads.
Polypropylene multifilament rope: It has a certain plush or fibrous appearance because it is composed of multiple single filaments. The touch is soft, and you can feel the gaps and interweaving between the fibers when you touch it.
4. Application scenarios
Polypropylene monofilament rope:
Due to its stiff nature, it is commonly used in situations where high requirements are placed on maintaining the shape of the rope. For example, in the agricultural field, as a support rope for climbing plants such as grape stands and bean stands, it can maintain a good straight shape and help plants climb.
In some simple hand woven or decorative scenes, the stiffness of single wire ropes can make the woven items more three-dimensional.
Polypropylene multifilament rope:
Due to its good flexibility, it is widely used in situations that require frequent bending and knotting. For example, as a fishing net rope in the fishing industry, it can be easily woven and knotted, and can also withstand a certain amount of tension; In outdoor sports, it is easy to carry and use as a climbing rope, camping rope, etc.
In the packaging industry, multifilament ropes can be used to bind various irregularly shaped items and can fit the contours of the items well.
