Hot-melt yarn and water-soluble yarn are two different functional fibers. Their main differences lie in their dissolution characteristics and application fields.
1. Solubility properties:
- Water-soluble yarn: a soluble yarn spun from vinylon staple fiber through ring spinning. It can be dissolved in water of about 0-100 degrees when fully exposed to water, and dissolves like salt.
- Hot melt yarn: also known as low melting point yarn or fusible yarn. When the temperature reaches the melting point, the hot melt yarn will gradually melt and bond other yarns together. The melting point of hot melt yarn can be adjusted between 85℃ and 180℃.
2. Material and production:
- Water-soluble yarn is mainly made of vinylon staple fiber, which has good water-soluble properties and can be dissolved in water according to different needs.
- Hot melt yarn is usually made of polyester, polyamide and other materials and has the characteristics of high strength, chemical corrosion resistance and easy molding.
3. use:
- Water-soluble yarn: often used for embroidery positioning, water-soluble non-woven fabric raw materials, companion spinning fibers, etc. It can increase yarn strength, improve weaving efficiency, and is used to produce water-soluble worsted yarn and high-grade pure wool fabrics.
- Hot melt yarn: widely used in outdoor sports uppers, casual uppers, sofa fabrics, curtains and window screens, carbon fiber cloth shaping, chenille yarn, Bondi yarn, high-end suit linings, lace and glove overlock yarns, etc. .
4. Environmentally friendly features:
- Water-soluble yarn is naturally biodegradable. After being dissolved in water, it can be naturally biodegraded or rapidly degraded in activated sludge without causing any pollution to the environment.
- Hot melt yarn is an environmentally friendly material that can effectively reduce environmental pollution and has pollution-free characteristics.
5. Other features:
- Water-soluble yarn has good mechanical properties, including strength, plasticity, hardness, impact toughness and other characteristics. It has good weather resistance and has better hygroscopicity than vinylon short fiber.
- Hot melt yarn has the characteristics of high strength and wear resistance, waterproof performance, chemical corrosion resistance, and easy molding.
In summary, although water-soluble yarn and hot-melt yarn are both functional fibers, their dissolution mechanisms, materials, uses and environmental protection characteristics are obviously different. Water-soluble yarn focuses on water solubility and is suitable for applications that require dissolution in water; while hot-melt yarn focuses on thermal bonding and is suitable for scenes that require thermal bonding.
