What should technicians do to reduce the possibility of fiber distortion while hot melt seaming?

To minimize fiber distortion during hot melt seaming, it is essential to avoid excessive heat. High temperatures, particularly those approaching or exceeding 300 degrees, can compromise the integrity of the fibers in the carpet or flooring material being worked on. At elevated temperatures, fibers can soften, leading to distortion or melting, which ultimately affects the appearance and performance of the installation.

Keeping temperatures below this threshold ensures that the adhesive performs effectively without compromising the structure of the fibers. Therefore, maintaining a lower temperature is key to preserving the quality of the material and achieving a successful seam.

The other options either imply practices that could lead to increased risk of damage or do not directly address the fiber distortion concern. For instance, using a higher adhesive temperature could exacerbate the issue, while increasing pressure might not necessarily resolve the problem of fiber distortion. Additionally, maintaining high humidity levels might influence adhesive curing but does not directly correlate with minimizing heat-related fiber damage. Hence, the focus on avoiding extreme temperatures is crucial in this context.
