Hot melt yarns with different melting temperatures have different properties and are used for different applications. The melting temperature of a hot melt yarn determines its viscosity, strength, and bonding ability.
Here are the key differences between hot melt yarns with different melting temperatures:
Low melting temperature (less than 150°C): Hot melt yarns with low melting temperatures have a low viscosity and are best used for applications where a strong bond is not required. They are often used in packaging and labeling applications.
Medium melting temperature (150-180°C): Hot melt yarns with medium melting temperatures have a moderate viscosity and are best used for applications where a strong bond is required. They are often used in textiles and non-woven fabrics.
High melting temperature (180-220°C): Hot melt yarns with high melting temperatures have a high viscosity and are best used for applications where a very strong bond is required. They are often used in industrial applications, such as filters and technical textiles.
In general, the melting temperature of a hot melt yarn affects its bonding properties and determines the conditions under which it can be used. Hot melt yarns with higher melting temperatures are typically stronger and more durable, while those with lower melting temperatures are more flexible and easier to work with. The choice of hot melt yarn will depend on the specific requirements of the application and the desired end result.
