3D Spacer Fabrics – Innovative, Engineered, and Performance Driven


3D spacer fabrics go above and beyond to provide solutions for a wide variety of applications. If you’re looking for an innovative fabric that’s breathable, cushioned, absorbent, resilient, soft to the touch, and pleasing to the eye, then look no further.

A sustainable alternative to foam, spacer fabrics offer greater durability, retain their cushioning properties, and are recyclable, making them better for the environment. Checking every box, Apex Mills is the expert at constructing the perfect spacer fabric for your product.

What Is 3D Spacer Fabric?

3D spacer fabrics have three layers. These include two surfaces — a face and a back — that sandwich a layer of vertical filler yarns to provide varying levels of thickness for volume and cushioning. Each layer can possess unique characteristics, making the possible variations virtually limitless.

3d spacer fabric example

Considered a technical textile, spacer fabrics are engineered based on their end-use, with three main variables to consider. The first is fabric construction – the face and back of the fabric can be a solid knit or a mesh design. A mesh face allows for greater airflow, while a solid knit would enable the textile designer to apply a performance-enhancing additive to the center fibers, perhaps for insulation or molding properties. The fabric’s thickness can also be modified based on the application’s needs. Our spacers typically range from 1.5mm up to 10mm in thickness.

The next variable is the choice of yarns selected to address the performance goals of the textile. You might want a polyester or nylon fabric for strength and durability or a yarn with silver, copper, or zinc for inherent antimicrobial attributes. Yarns can be sustainable, made from recycled plastic chips, or even biodegradable.

The process used to dye and finish the fabric is the third way to create the ideal fabric for its intended use. The finishing process selected can impact a fabric’s utility, texture, and color. You can learn more in our Guide to Fabric Finishes.

How Is Spacer Fabric Made? 

Spacer fabrics are made on double-needle bar (DNB) machines. These machines have two independent needle bar systems, each used to knit a side of the fabric. By traversing yarns, called spacer yarns, between the two fabric faces, the machine creates the innermost layer. Monofilament yarns are often used for the innermost, or pile layer, as they are more resilient and stiffer, enabling a greater separation of the two faces. Multifilament yarns can also be used, but they are softer and limit the thickness of the spacer to about 4mm.

Physical Properties and Benefits of 3D Spacer Fabrics

Due to its physical attributes, combining lightweight construction, durability, and enhanced performance, 3D spacer fabric is suitable for various applications.

The unconventional three-layer structure of 3D spacer fabrics offers:

  • Durability and strength: Spacer fabrics are strong and wear-resistant, made from synthetic fibers like polyester. 
  • Breathability: The open, airy structure minimizes weight. The gaps allow excellent airflow, improving comfort and reducing heat buildup.
  • Moisture management: Spacer fabrics made from polyester and nylon wick away moisture, keeping surfaces dry.
  • Cushioning and impact resistance: The spacer structure offers shock absorption and cushioning.

Customization Offers More Benefits

Several aspects of 3D spacer fabrics are customizable for enhanced performance in specialized applications:

  • Thickness: The thickness of the spacer fabric can be adjusted by altering the distance between the outer layers to meet cushioning, thermal insulation, or structural strength needs.
  • Material: Different fibers, like polyester, nylon, or natural blends, can be used to optimize durability, breathability, or eco-friendliness.
  • Pattern: The weave or knitting structure enhances the fabric’s flexibility, stretch, and aesthetic. You can customize these elements by adjusting the pattern of the weave or knit.
  • Shape and size: Spacer fabrics can be cut, molded, or sewn into intricate shapes, making them ideal for unique designs like medical braces, insoles with arch support, or automotive seat panels.

Customization can enhance the performance of 3D spacer fabrics in several ways:

  • Improved ventilation
  • Targeted cushioning and support 
  • Thermal regulation
  • Enhanced moisture management
  • Increased fire resistance

Dyeing and Finishing 3D Spacers

Apex Mills delivers advanced, customized 3D spacer fabrics for various industries and applications, including aeronautics, military, health care, apparel, automotive, and many more. All our 3D knitted spacer fabrics are crafted from 100% polyester materials certified under STANDARD 100 by OEKO-TEXT, and ISO 9001:2015 ensuring safety, quality, and compliance.

The acquisition of our Insight Textiles facility in Virginia strengthens our ability to produce innovative fabric solutions. This advanced facility offers state-of-the-art fabric dyeing, finishing, and surface treatments, such as fire retardant, moisture-wicking, antimicrobial, temperature control, and abrasion-resistant solutions. A standout feature is the facility’s cutting-edge dye lab, a hub for color innovation and development. The lab enhances our efforts to create custom colors and pioneer finishes like our eco-friendly antimicrobial treatment.

What Are Some Uses for Spacer Fabric?

Because spacer fabrics are highly customizable, they appeal to product designers across industries.

  • Footwear and Apparel: From running shoe uppers to orthotic padding and other shoe insoles, 3D fabrics help support feet and increase comfort. Spacers used in intimate apparel and athletic wear promote higher breathability, temperature regulation, and drapability.
  • Architectural: Spacer fabrics are soft, porous, and voluminous, making them ideal for sound absorption. Many buildings include insulation materials made from 3D fabrics to control noise indoors.
  • Automotive: While foams are common cushioning materials for automotive interiors, spacer fabrics are rising in popularity for this application, as they are lightweight and stay in good condition for more extended periods. Spacer fabrics are often used in car seat construction for their breathability, ideal for ventilation and passenger comfort.
  • Furniture: In place of foams, several furniture manufacturers use spacer fabrics for cushion pads, mattresses, and other body support furniture.
  • Medical: Spacer fabrics can be breathable and gentle, making them ideal for pressure wound protection products used in the medical field.
  • Geotextiles and Filtration: We have seen an increase in the use of warp knit spacer fabrics in the geotextile and environment protection sectors. With the ability to create each layer for a specific goal, spacers are becoming more widespread in erosion control, soil reinforcement, separation, filtration, and drainage applications.

Want to Know More? Spacer Fabric FAQs

Is It Water Resistant?

You can customize select spacer fabric faces to be water resistant. Though 3D fabrics are naturally porous, you can coat them to increase their moisture resistance. Water-resistant spacer fabrics are especially valuable in the medical industry, as health professionals use them to dress and protect wounds from getting wet.

Is It Machine-Washable?

Spacer fabrics are machine-washable, so products made from 3D spacers can easily integrate into everyday life.

Is It Environmentally Friendly? 

3D spacer fabric is a viable replacement for foam in many industries. Foam degrades quickly and creates large amounts of waste. For a more sustainable option, you can choose spacer fabrics made from organic yarns, biodegradable yarns, or recycled yarns. For greater ecological sensitivity you can create colors with low eco-impact dyes. Find a textile manufacturer that will work with you to create quality products while reducing your environmental footprint.
