Hot melt yarn and hot melt thread are two types of textile products with thermoplastic properties, which might be confused in certain applications but are actually different products with distinct characteristics and uses.
Here are the main differences between hot melt yarn and hot melt thread:
Form and Structure:
Hot melt yarn: Typically refers to yarns with thermoplastic properties, which can be monofilament, multifilament, or plied yarns made from one or more types of fibers, at least one of which has thermoplastic properties.
Hot melt thread: Usually monofilament or multifilament with thermoplastic properties, mainly used for sewing, bonding, and other purposes.
Material Composition:
Both hot melt yarn and hot melt thread can be made from various materials, including but not limited to polyester, nylon, polypropylene, etc., but they may have different melting points and thermoplastic properties.
Application Fields:
Hot melt yarn: Widely used in textiles, clothing, shoe materials, furniture, automotive interiors, medical and health fields, providing functions such as adhesion, shaping, reinforcement, etc.
Hot melt thread: Mainly used for sewing, bonding, embroidery positioning, etc., especially when high-temperature adhesion or fixation of materials is required.
Process Characteristics:
Hot melt yarn may undergo specific thermal treatment processes during production to ensure its thermoplastic properties.
Hot melt thread may be specially designed during production to adapt to specific thermoplastic processes, such as hot melt bonding or hot melt sewing.
Performance Requirements:
Hot melt yarn needs to have good thermoplastic adhesion performance, sufficient strength, and appropriate melting points.
Hot melt thread, in addition to having thermoplastic properties, also needs to have good sewing performance and durability.
Environmental Characteristics:
Both can be environmentally friendly materials, but their impact on the environment and recyclability during production and use may differ.
Market Positioning:
Hot melt yarn may be more of a supplementary textile material, providing specific functionality.
Hot melt thread is more of a sewing material, used to improve the production efficiency and quality of products.
Technical Development:
The technical development of both hot melt yarn and hot melt thread focuses on improving thermoplastic performance, reducing production costs, and enhancing product durability.
In summary, although hot melt yarn and hot melt thread both have thermoplastic adhesion properties, their form, structure, material composition, application fields, and performance requirements are different. When selecting for use, it is necessary to determine which product to use based on specific application needs and process conditions.
