As an innovator in high-performance thermal bonding materials, nylon thermal fuse with its characteristics of low-temperature melting, efficient bonding, environmental friendliness and stability, is becoming the preferred solution in the textile, footwear and apparel, automotive and other industries. The following elaborates on the core technology of melting point, application advantages and scenarios:

1. Melting point characteristics: Scientific proportioning, precise temperature control

Low-temperature melting, high efficiency and energy saving

The melting point of nylon thermal fuse can be precisely controlled within 85°C-130°C (customized according to customer requirements), which is significantly lower than that of traditional fibers. This characteristic enables it to melt rapidly during dry heat or wet heat processing, avoiding damage to other fibers (such as polyester and cotton) caused by high temperatures, while reducing energy consumption costs.

Hydrogen bond regulation ensures stable performance

Through the design of modified polyamide (PA) molecular chains, the ratio of methylene groups to amide groups is optimized, and the hydrogen bond density is adjusted to achieve precise control of the melting point. For instance, the even-numbered methylene structure can increase the hydrogen bond density, enhance the crystallinity and thermal stability, and ensure the stability of the bonding strength after melting.

Environmentally friendly and pollution-free

The melting process does not require chemical adhesives, avoiding the release of volatile organic compounds, meeting the EU environmental protection standards, and is suitable for the export of high-end products.

Ii. Application Scenarios: Adaptable to the demands of multiple fields

Weaving of shoes and clothing

Feizhi upper/sock shoes: 85°C low-melt-point filaments quickly bond during wet heat setting, maintaining the fabric's breathability and three-dimensional effect, and solving the problem of traditional glue hardening.

Elastic webbing/lace: The 110°C melting point filament provides high adhesion, is resistant to repeated stretching, and is suitable for sportswear and underwear accessories.

Industry and Automobiles

Automotive interior/airbag: The high-temperature resistant (130°C) model maintains adhesive stability in a humid and hot environment and has passed the anti-yellowing test (≥ level 4), avoiding discoloration over long-term use.

High-strength Bondi thread: The polarity of 85°C filament and nylon fiber is matched. After bonding, the strength is increased by 30%, and it is resistant to water washing and dry cleaning agent corrosion.

Home Furnishings and Decoration

Chenille yarn/wool carpet: The melting point and fiber blending ratio are coordinated to achieve seamless shaping, prevent fiber shedding, and extend product lifespan.
