Two-component Foldable Monofilament Yarn Manufacturers

BOSIDI bicomponent hot melt monofilament is an engineered two-component monofilament developed for applications where thermal bonding and structural stability are required in the same yarn. As part of our Two-Component Hot-Melt Monofilament range, it combines different thermal behaviors within one filament so that heat can activate the bonding component while the supporting component helps retain the required structure.

The current product is available in diameters from 0.11 mm to 1.5 mm, with a listed fracture strength of 6.7–7.1 N and fracture elongation of 20.6–23.1%. It can be considered for thermally bonded technical textiles, footwear structures, automotive textile components, nonwoven assemblies and other applications requiring heat-activated joining without relying entirely on liquid adhesive systems.

How Bicomponent Hot Melt Monofilament Works

• Thermal bonding: The heat-responsive component softens or melts during the heating process and helps bond adjacent textile structures.

• Structural support: The higher-temperature supporting component helps the yarn maintain the required form after bonding.

• Cleaner processing: Thermal bonding can reduce dependence on separately applied liquid adhesives in suitable textile constructions.

• Controlled textile structure: The monofilament can be woven, knitted or incorporated into engineered textile structures before thermal activation.

• Application-specific performance: Diameter, thermal response and mechanical behavior should be selected according to the substrate and bonding process rather than diameter alone.

Custom Bicomponent Monofilament for Your Process

For new projects, provide the following information with your inquiry:

• Target filament diameter

• Finished product or textile application

• Heating or thermocompression temperature

• Heating time or line speed

• Substrate materials to be bonded

• Required flexibility or stiffness

• Required breaking strength and elongation

• Woven, knitted, braided or nonwoven construction

• Sample quantity and estimated annual demand

Where to Use Bicomponent Hot Melt Monofilament

How to Select the Right Bicomponent Monofilament

The correct product should be selected according to your thermal process rather than by diameter alone.

• For low-stiffness textile structures, prioritize the smallest diameter that still meets the required mechanical strength.

• For shaped or foldable textile components, tell us the required bending behavior and whether the structure must remain flexible after thermal bonding.

• For thermal lamination, provide your actual processing temperature and dwell time so that the filament can be matched to the heating process.

• For woven or knitted applications, specify machine type, mesh or fabric construction and yarn position because filament stiffness and diameter directly affect processability.

• For applications exposed to repeated bending, also provide the expected flexing requirement so that mechanical performance can be evaluated before bulk production.

Bicomponent Hot Melt Monofilament vs Conventional Monofilament

FAQ

What is bicomponent hot melt monofilament?

It is a monofilament made with two functional material components. One component provides the required thermal response for bonding, while the other helps maintain the structural properties of the filament during and after heating.

What diameter can BOSIDI supply?

The current product page lists a diameter range of 0.11 mm to 1.5 mm. Please provide your required diameter and textile construction when requesting a quotation.

Is 220°C the recommended bonding temperature?

The current product data lists a melting degree of 220°C, but this should not automatically be treated as the recommended processing temperature. Actual bonding conditions depend on the component structure, substrate, heating method and dwell time. Send us your process conditions for evaluation.

Can this yarn replace glue?

In suitable textile constructions, heat-activated monofilament can reduce or eliminate separately applied adhesives. Whether it can fully replace adhesive depends on the required bond strength, substrate and production process.

What information is required for a custom specification?

Please provide diameter, bonding temperature, end application, substrate material, textile construction, required flexibility, mechanical requirements and estimated order quantity.

Can I test the monofilament before bulk production?

For thermal-bonding applications, sample testing is recommended because bonding performance depends strongly on the customer's actual heating equipment, textile construction and substrate materials.
