Understanding Carded Chem-Bond and Thermal Bond Nonwovens: The Essential Guide

 In today’s manufacturing world, nonwoven fabrics play a critical role across various industries. From hygiene products to automotive interiors, nonwovens provide cost-effective, versatile solutions. Two common techniques used in the production of nonwoven fabrics are carded chem-bond and thermal bond. Both methods have unique properties that make them suitable for specific applications. In this blog, we will delve into the differences, benefits, and applications of these bonding techniques, helping you make informed decisions for your projects. Let’s explore how these processes work and why Sommers Inc. is your trusted partner for nonwoven materials.



What is Carded Chem-Bond?

Carded chem-bond refers to a process in which fibers are aligned and bonded using a chemical adhesive. The fibers are first carded, which involves disentangling and orienting them in parallel to form a web. Afterward, a chemical adhesive is applied to bond the fibers together, giving the material strength and durability. This process is particularly useful when manufacturers require nonwovens with specific properties like softness, high tensile strength, or moisture resistance.

Key Benefits of Carded Chem-Bond Nonwovens
  • Durability: The chemical adhesive provides strong bonding between fibers, making the material more durable for applications like automotive linings or filtration.
  • Customization: Different adhesives can be used to create nonwovens with specific characteristics, such as softness or resistance to moisture.
  • Versatility: This process works well with a variety of fiber types, including synthetic and natural materials, allowing for tailored solutions.

Carded chem-bond nonwovens are commonly used in applications such as hygiene products (e.g., diapers), wipes, medical fabrics, and upholstery. Their customizable properties make them a go-to choice for manufacturers looking for high-performance fabrics.

What is Thermal Bond?

In contrast to the chemical bonding method, thermal bonding involves the use of heat and pressure to fuse fibers together. This technique typically uses thermoplastic fibers, which melt when heated and bond upon cooling. The fibers are carded similarly to the chem-bond process, but instead of using adhesives, heat is applied to create the bonds between fibers. The result is a fabric that is lightweight yet strong, with a smooth finish.

Key Benefits of Thermal Bond Nonwovens
  • Eco-Friendly: Since thermal bonding does not rely on chemical adhesives, it is a more environmentally friendly process. This makes it ideal for products like disposable wipes, hygiene products, and packaging materials.
  • Cost-Effective: The absence of chemicals reduces the cost of production, making thermal bonding a budget-friendly option.
  • Strong and Lightweight: The thermal bond process creates nonwovens that are both strong and lightweight, making them ideal for applications like automotive interiors, insulation, and even apparel.

Thermal bond nonwovens are frequently used in applications where strength, lightweight, and eco-friendliness are priorities. These include packaging materials, insulation, and hygiene products like face masks and medical gowns.

Choosing Between Carded Chem-Bond and Thermal Bond

When deciding which bonding method is best for your application, consider the following factors:

  1. End-Use Requirements: If you need a fabric that is highly durable and can withstand wear and tear, carded chem-bond may be the right choice. On the other hand, if you’re looking for lightweight, cost-effective materials, thermal bond might be the better option.

  2. Environmental Considerations: For applications that require eco-friendly solutions, thermal bonding is a greener option since it eliminates the use of adhesives.

  3. Customization Needs: If your product requires specific characteristics such as moisture resistance or a high level of softness, carded chem-bond can be tailored to meet these requirements through the selection of different adhesives.
