As a supplier of bump interlining fabric, one question I often encounter from customers is whether bump interlining fabric is waterproof. This is a crucial concern, especially for applications where protection against water is necessary. In this blog post, I'll delve into the characteristics of bump interlining fabric, explore its waterproof properties, and discuss various factors that influence its performance in wet conditions.
Understanding Bump Interlining Fabric
Bump interlining fabric is a type of interlining that is commonly used in the garment industry to add structure, shape, and stability to clothing. It is typically made from a combination of fibers, such as polyester, cotton, or a blend of both. The fabric is known for its unique bumpy texture, which is created through a special manufacturing process. This texture gives the fabric its name and provides it with several advantages, including increased loft, improved drape, and enhanced durability.
Bump interlining fabric comes in various types and weights, each designed for specific applications. For example, lightweight bump interlining is often used for delicate garments, such as blouses and shirts, while heavier weights are suitable for outerwear, such as jackets and coats. The choice of bump interlining fabric depends on the desired effect, the type of garment, and the specific requirements of the project.
Is Bump Interlining Fabric Waterproof?
The short answer is that bump interlining fabric is not inherently waterproof. Most bump interlining fabrics are made from natural or synthetic fibers that are porous, meaning they allow water to penetrate through them. However, this does not mean that bump interlining fabric cannot be used in applications where water resistance is required. There are several ways to make bump interlining fabric more water-resistant, which I'll discuss in the following sections.
Factors Affecting Waterproofness
Several factors can affect the waterproofness of bump interlining fabric. These include the type of fibers used, the fabric construction, the finish applied to the fabric, and the presence of any additional waterproofing treatments.
- Type of Fibers: Natural fibers, such as cotton and wool, are generally more absorbent than synthetic fibers, such as polyester and nylon. This means that bump interlining fabric made from natural fibers is more likely to absorb water and become wet. Synthetic fibers, on the other hand, are less absorbent and can provide better water resistance.
- Fabric Construction: The construction of the fabric can also affect its waterproofness. Fabrics with a tight weave or a high thread count are generally more water-resistant than fabrics with a loose weave or a low thread count. Additionally, fabrics with a laminated or coated finish are more likely to be waterproof than uncoated fabrics.
- Finish: The finish applied to the fabric can also improve its waterproofness. Water-repellent finishes, such as fluorocarbon coatings, can help to prevent water from penetrating the fabric. These finishes work by creating a barrier on the surface of the fabric that repels water.
- Additional Waterproofing Treatments: In some cases, additional waterproofing treatments may be applied to bump interlining fabric to enhance its waterproofness. These treatments can include the use of waterproof membranes, such as Gore-Tex or eVent, or the application of a waterproof spray or coating.
Making Bump Interlining Fabric More Waterproof
While bump interlining fabric is not inherently waterproof, there are several ways to make it more water-resistant. Here are some common methods:
- Choose a Synthetic Fiber: As mentioned earlier, synthetic fibers are generally more water-resistant than natural fibers. When selecting bump interlining fabric, consider choosing a fabric made from polyester or nylon. These fibers are less absorbent and can provide better water resistance.
- Look for a Tight Weave: Fabrics with a tight weave or a high thread count are generally more water-resistant than fabrics with a loose weave or a low thread count. When shopping for bump interlining fabric, look for fabrics with a tight weave or a high thread count.
- Apply a Water-Repellent Finish: Water-repellent finishes can help to prevent water from penetrating the fabric. These finishes work by creating a barrier on the surface of the fabric that repels water. You can apply a water-repellent finish to bump interlining fabric using a spray or a coating.
- Use a Waterproof Membrane: Waterproof membranes, such as Gore-Tex or eVent, can provide excellent waterproofing performance. These membranes are typically laminated to the fabric to create a waterproof barrier. If water resistance is a critical requirement, consider using a bump interlining fabric with a waterproof membrane.
Applications of Waterproof Bump Interlining Fabric
Waterproof bump interlining fabric can be used in a variety of applications where protection against water is necessary. Here are some common applications:


- Outerwear: Waterproof bump interlining fabric is commonly used in the production of outerwear, such as jackets, coats, and rainwear. The fabric provides structure and shape to the garment while also protecting the wearer from the elements.
- Sportswear: Sportswear, such as running jackets, cycling jerseys, and ski pants, often requires water resistance. Waterproof bump interlining fabric can be used to enhance the performance of these garments and keep the wearer dry and comfortable.
- Upholstery: Waterproof bump interlining fabric can also be used in upholstery applications, such as outdoor furniture and boat seats. The fabric provides durability and water resistance, making it suitable for use in wet or damp environments.
