In actual use, the rope will be affected by various environmental loads such as light, humidity, temperature and chemicals. When the conditions of use, environmental conditions and duration of use change, important properties such as the breaking capacity and elongation of the rope will also change.
1. The influence of light on the rope
The atmospheric environment affects all textile fibers and fiber ropes. Atmospheric environmental factors include wind, rain, light, temperature, and dirt deposits on the ropes, among which solar radiation has the greatest impact, especially related to the aging of synthetic fibers. Ropes are exposed to sunlight, ultraviolet and infrared rays are the most harmful.
2. The effect of moisture absorption on ropes
Water is the most important environmental factor affecting the performance of synthetic fiber ropes. In water, the physical and mechanical properties of the rope, such as breaking capacity, elongation, diameter, and mass, change. The rope absorbs moisture when it is immersed in water. For plant fiber ropes, water not only penetrates into fiber cells, but also penetrates into the gaps between fibers, rope yarns and strands. When the rope is dry, these gaps filled with air are replaced by water.
3. The influence of temperature and chemicals on ropes
Synthetic fiber materials are thermoplastic materials, so their physical and mechanical properties depend on temperature to some extent. If the temperature reaches the softening point of the material, irreversible damage will occur.
