DFN-25106 Spacer Mesh — Protective Vest Backpack Padding 4mm

1. Product Core Advantages

3D Spacer Structure — Impact Absorption for Active Gear

The DFN-25106 is a warp-knitted sandwich construction with a ribbed top face, a vertical fiber spacer core, and a fine-mesh backing. The 4mm spacer core acts as a shock-absorbing buffer layer, spreading impact forces and preventing hard surfaces or pack frames from transferring pressure directly to the body — the same cushioning principle used in professional protective equipment.

Ventilated Air-Channel Core — All-Day Wear Without Heat Build-Up

The vertical connecting fibers create continuous micro air channels between the ribbed face and the mesh backing. For people wearing protective vests, sport supports, or heavy backpacks for extended periods, this ventilation system continuously dissipates body heat and moisture — eliminating the sweat-soaked discomfort that solid foam and EVA padding cause inside enclosed gear.

High-Density 430gsm Support — Holds Form Under Load

At 430±30 grams per square meter, this fabric provides firm, even support for heavy loads. The dense warp-knit structure resists compression from pack weights and equipment pouches, maintaining its cushioning thickness over extended service — no permanent flattening like conventional foam that degrades after weeks of regular use.

Elastic Ribbed Face — Conforms, Grips, and Recovers

The parallel raised ribs with an elastic knit base give the fabric two-way stretch that conforms to body curves and curved pack panels, holding inserts and pads firmly in place. The elastic recovery returns the fabric to its original profile after repeated compression cycles — critical for equipment that is packed, worn, and unpacked daily.

Durable Warp-Knit Construction — Tear-Resistant and Washable

The warp-knit construction delivers high tear and abrasion resistance compared to woven fabrics and foam laminates. The dark matte finish minimizes reflection, and the fabric withstands the rough handling and field abuse that outdoor and professional gear endures. Fully machine-washable for daily hygiene and easy care.

3. Application Scenarios

Sports & Protective Vests

The primary application is as the breathable backing and padding layer in sports protective vests and body-support gear. The 4mm spacer core separates the hard outer shell from the body, absorbing impact energy while the air channels keep the wearer cool during extended activity — the two factors that most affect comfort and wear compliance.

Outdoor & Travel Backpacks

For backpack back panels, shoulder strap padding, and hip belt liners, this fabric distributes load pressure across a wider area, reducing strap-digging during heavy carries. The elastic face conforms to the wearer's back, while the mesh backing against the pack frame stays breathable — essential for multi-hour hikes with full equipment.

Impact Protection Inserts

Cut to shape, the fabric serves as a flexible impact-absorbing insert for elbow pads, knee pads, helmet liners, and chest protection. Unlike rigid foam that cracks with repeated impacts, the spacer knit absorbs and recovers — the insert returns to full thickness after every hit.

Professional & Work Equipment

From tool belt cushioning to camera bag lining and work harness padding, the 4mm profile fits into tight spaces where thick foam cannot. The matte black finish suits the understated requirement of professional gear and everyday carry items.

OEM Outdoor Gear Production

For gear manufacturers, this fabric is supplied in 150cm-wide rolls for efficient cutting — vest panels, pack frames, and strap liners cut cleanly with standard dies. Consistent 430gsm density and thickness across rolls ensures uniform cushioning in every production batch.

5. FAQ

Q: What is the minimum order quantity (MOQ)?

A: Standard MOQ is 500 meters per roll (single color). Sample orders of 30–100cm swatches are available for evaluation. Die-cut panel customization starts at 500 units per part number.

Q: Can this fabric be used next to the skin?

A: Yes. The fine-mesh backing is smooth and low-irritation, suitable for direct skin contact in vest and strap applications. The 3D air channels keep the contact surface dry. For hygienic applications, the fabric is machine-washable without loss of cushioning performance.

Q: How does this compare to foam padding?

A: Three decisive advantages: (1) Breathability — foam traps heat and sweat; the spacer core ventilates continuously; (2) Recovery — foam permanently flattens under load; the warp-knit returns to full thickness; (3) Weight — spacer fabric provides equivalent cushioning at a fraction of foam's weight, critical when every gram of carried gear matters.

Q: Can you supply cut pieces to our specifications?

A: Yes. We offer die-cut and CNC-cut panels to your exact dimensions for vest panels, pack frames, and strap liners. Cut pieces are supplied with clean sealed edges that resist fraying. Custom cutting requires a 1–2 week tooling lead time.

Q: Does this fabric offer flame-retardant options?

A: The base fabric is a polyester/spandex warp knit. Fire-retardant (FR) treated versions and flame-retardant yarn options are available for contract and specialized applications — please specify your standard (e.g., NFPA, EN) when ordering so we can match the correct treatment.
