Difference between polyester rope and nylon rope

The difference between polyester rope and nylon rope, the following will introduce the difference between polyester rope and nylon rope from the aspects of material, wear resistance, light resistance, corrosion resistance, wet performance, extensibility, combustion method and hand feel.

material

From the material point of view, polyester rope is made of polyester high-strength industrial yarn; Nylon rope is made of nylon high strength yarn. Through the experiment of monofilament tensile tester, there is basically no difference in the strength of these two kinds of fibers, and the strength is about 8.3CN/dtex.

That is to say, it shows that polyester rope and nylon rope bear the same load under the condition of the same thickness, the same twist and the same knitting method.

So, what’s the difference between polyester rope and nylon rope? Which is better, nylon rope or polyester rope?

Nylon wear resistance, polyester light resistance.

Nylon is alkali-resistant but not acid-resistant, and polyester is acid-resistant and alkali-resistant.

The wear resistance of nylon rope ranks first among synthetic fiber ropes, and the wear resistance is very good. Polyester rope has good light resistance and ultraviolet resistance: very good.

Nylon rope has the longest anti-aging and anti-corrosion time; Polyester rope is easy to get moldy in the rain.

Wet state

In the wet state, the breaking strength and elongation of nylon will decrease by about 10%. In the wet state, the breaking strength and elongation of polyester fiber can be consistent with that in the standard state.

tractility

When nylon rope is stretched, it has a “memory” of returning to its original length. For this reason, nylon rope is the best rope to absorb impact load, which can last 4-5 times longer than natural fiber. Therefore, the climbing rope, climbing rope, power rope, fall protection safety rope, lanyard, etc., which need to absorb impact, are made of nylon.

combustion method

The simplest difference between nylon and polyester is the combustion method: polyester can emit very strong black smoke when burning; Nylon burns with white smoke. There is also a look at the residue after burning: the residue of polyester will be crushed after burning, and the residue of nylon will become plastic.

feel

Polyester feels rough; Nylon feels smoother.

To sum up, polyester and nylon have the same strength, but each has its own advantages.

That’s the difference between polyester rope and nylon rope.
