As the best-selling functional fibers in recent years, water-soluble yarn and hot-melt yarn should be familiar to everyone. Both are related to temperature, and both are yarns, but what is the difference?
Different concepts
1. Water-soluble yarn is a kind of soluble yarn spun from vinylon staple fiber by ring spinning. Simply put, it is a kind of thread that the yarn can melt like salt when it is fully contacted with water. It has better water solubility and can be dissolved in water of about 0-100 degrees according to different needs. A thread that dissolves like salt when fully touched by water.
2. Hot fusible filament, also known as low melting point filament or fusible filament, is one of the most rapidly developing functional fibers in recent years. As the name suggests, when the temperature reaches the melting point, the thermal fuse gradually melts, bonding the other yarns together. Hot fuse is divided into two types: polyester hot fuse and nylon hot fuse. The melting point can be controlled between 85°C and 180°C by adjusting the characteristics of raw materials.
The nylon hot fuse is made by spinning low-melting polyamide. Low-melting polyamide is a modified polyester. The nylon hot-melt yarn made from low-melting polyamide has the advantages of low melting point, high thermal bonding strength and stable physical and chemical properties.
