- Low Profile Knit Loop - By The Yard

Compare

Looking for a thinner, more flexible loop material that still delivers dependable engagement strength? Low Profile Knit Loop is engineered for applications where bulk, weight, and stiffness must be kept to a minimum. It pairs with a wide range of VELCRO® Brand hook options to create secure, repeatable fastening systems for soft goods, displays, straps, medical devices and more.

Why Choose Low Profile Knit Loop?

Low Profile Knit Loop (VELCRO® Brand 3610 and 3905) offers a streamlined alternative to traditional woven loop. It delivers a softer hand and a flatter profile. This makes it ideal for:

  • Soft goods manufacturing: apparel panels, removable pads, children’s products, sports gear.

  • Medical & orthopaedic applications: patient straps, positioning devices, compression wraps where comfort against skin is essential.

  • Display & packaging: lightweight closures, header cards, point-of-sale attachments.

  • Commercial and industrial use: instrument wraps, cable management, low-bulk fastening systems.

Its lower loft helps reduce overall assembly thickness while still providing reliable shear and peel performance when paired with compatible hooks such as HTH 830 and HTH 805. The knit construction offers durability through repeated cycles and drapes easily over contoured surfaces.

iTapeStore offers Low Profile Knit Loop by the yard with no minimum order quantity, making it accessible for prototyping, small production runs or full-scale manufacturing.
Knit Loop Data Sheet

Technical Specifications

While tensile and shear values vary depending on the hook style used, Low Profile Knit Loop typically delivers consistent performance across a broad range of applications. Key characteristics include:

  • Material: 100% nylon knit loop.

  • Profile: Low loft for reduced bulk and improved drape.

  • Recommended Hook Pairings: VELCRO® Brand HTH 830, HTH 805 and other standard hook constructions.

  • Cycle life: Designed for repeated openings/closures without significant loss of holding force.

  • Temperature Performance: Suitable for typical indoor environments. Nylon loops are generally stable in moderate outdoor conditions though long-term UV exposure may reduce life.

  • Substrate Compatibility: Can be sewn, stapled, ultrasonically welded or laminated. Works well in both textile and non-woven assemblies.

If you require adhesive-backed loop instead of sew-on loop, iTapeStore can add acrylic adhesives suitable for plastics, metals and high-surface-energy substrates.

Custom Converting Options

iTapeStore provides Made-in-USA converting services to meet the exact requirements of your build. Options include:

  • Slitting to custom widths for straps, packaging, or device assemblies.

  • Die-cutting into shapes, tabs or mounting patches.

  • Kitting & private-label solutions for OEMs and contract manufacturers.

  • Laminate-to-adhesive options for peel-and-stick loop assemblies.

Application Guide

To achieve optimal fastening performance:

  1. Choose the correct hook: Low Profile Knit Loop works best with HTH 830 or 805 for balanced shear and peel strength.

  2. Prepare the substrate:

    • For sew-on applications, use a consistent stitch pattern to maintain loop integrity.

    • For adhesive-backed assemblies, ensure surfaces are clean, dry and free of oils.

  3. Consider load direction: Shear loads maximise holding power compared to peel loads.

  4. Avoid excessive heat: Nylon loops may soften at elevated temperatures.

  5. Test before production: Always evaluate hook/loop engagement, cycle life and environmental exposure for your specific application.

FAQs

Is Low Profile Knit Loop weaker than standard loop?

Not necessarily. While it has a thinner profile, the knit construction still provides reliable engagement when paired with the correct hook. Strength varies by hook type, load direction and size.

Does it work on curved or flexible surfaces?

Yes. The soft nylon knit conforms well to contoured shapes, making it ideal for straps, wraps and soft goods.

Can I get it with adhesive backing?

Absolutely. iTapeStore can laminate acrylic adhesives suitable for metals, plastics, foams and textiles depending on your substrate.

Is this suitable for medical applications?

Low Profile Knit Loop is commonly used in medical soft goods. However, regulatory requirements differ by product class. Test and validate for your device before commercial use.
