There are several disadvantages of hot melt yarn, including:

Limited variety: Hot melt yarns are typically only available in a limited range of colors and fiber types, which can restrict their use in certain applications.
Limited strength: Hot melt yarns may not have the same strength and durability as other types of yarns, which can limit their use in heavy-duty applications.
Limited heat resistance: Because hot melt yarns are designed to melt at high temperatures to create bonds, they may not be suitable for use in high-heat environments.
Environmental concerns: The use of hot melt yarns can lead to waste and emissions during the manufacturing process, which can have negative environmental impacts.
Cost: Hot melt yarns may be more expensive than other types of yarns, which can make them less cost-effective for some applications.
