Description

Product Overview

PA hook & loop (Nylon Hook and Loop Fastener) is a high-quality hook and loop fastener product made primarily of nylon (Polyamide, PA). Nylon boasts excellent softness, abrasion resistance, and resilience, making it one of the most widely used hook & loop materials on the market. It is suitable for applications requiring repeated opening and closing, long-term fixation, and stable fastening force, and is a common standard specification in industries such as garment manufacturing, medical assistive devices, electronic wiring harnesses, and industrial assembly.

This product can be further subdivided into:

① Hard hook, brushed: The most common type of  hook & loop.

② Soft hook: Used for applications with low tensile strength requirements.

③ No brushed: The neatest appearance.

④ Hook and loop integrated: For a consistent appearance without distinguishing between hooks and loops.

① Hook and Loop Fasteners

Traditional hook and loop fasteners use PA66 nylon monofilaments for the hook side and PA6 for the loop side.

Characteristics:

• Stable Hook Shape: Nylon has excellent resilience and is not easily deformed or weakened by low usage.
• High Adhesion: The hook and loop counts meet the needs of most users, maintaining a certain level of tensile strength even after 10,000 repeated opening and closing cycles.
• Single Material: Offers the most consistent dyeing results.

Applications:

• Medical Products: Blood pressure cuffs, wristbands, knee pads, etc., providing comfort and preventing scratches.
• Baby Products: Baby diapers, bibs, children’s shoes, ensuring softness and preventing skin irritation.
• Electronic Products: Used to secure cables or accessories, preventing scratches on the plastic or metal casing of electronic devices.

② Soft Hook Fasteners

A variation of traditional hook and loop fasteners, featuring hooks formed by a finer diameter single yarn.

Characteristics:

• Soft and skin-friendly: The finer hooks are less likely to scratch or irritate the skin, making them suitable for items worn close to the body.
• Moderate adhesion: The fastening force is lighter than traditional hooks, making it easier to open and close repeatedly, suitable for applications requiring frequent adjustments.
• Worth protecting fabrics: More gentle on delicate fabrics (such as knitted fabrics and mesh).

Applications:

• Medical supplies: Blood pressure cuffs, wristbands, knee pads, etc., providing comfort and preventing scratches.
• Baby products: Baby diapers, bibs, children’s shoes, ensuring softness and preventing irritation to baby’s skin.
• Electronic products: Used to secure cables or accessories, preventing scratches on the plastic or metal casing of electronic devices.

③ Un-napped Loop Fasteners

By altering the weave and yarn selection, a more uniform nap is achieved.

Characteristics:

• Premium Texture: Visually neat, unlike the texture of traditional brushed surfaces.
• Moderate Adhesion: The fastening force is lighter than traditional napped surfaces, making it easier to open and close repeatedly, suitable for applications where appearance is paramount and tensile strength can be sacrificed.

Applications:

• Medical Products: Blood pressure cuffs, wristbands, knee pads, etc., providing comfort and preventing scratches.
• Baby Products: Baby diapers, bibs, children’s shoes, ensuring softness and preventing irritation to baby’s skin.
• Electronic Products: Used to secure cables or accessories, preventing scratches on the plastic or metal casing of electronic devices.

④ Uni-tape or Hook-and-Loop Hybrid Fasteners

Integrating the hook and loop into a single plane results in a simpler design and greater flexibility, revolutionizing the traditional hook and loop fastener system that requires two straps (hook and loop) for adhesion.

Features:

• Self-adhesive function: Folds in half and self-adheses, suitable for reusable straps.
• Convenience: No need to search for both sides or worry about storing the hook and loop separately.
• Fashion-resistant: The loop is slightly higher than the hook, reducing direct contact between the hook and fabric.

Medical Application (Tourette):

• Quick operation: The strap can be wrapped around the limb and fastened without length limitations. In emergencies, it can be quickly applied with one hand, buying precious time for hemostasis.
• Precise pressure adjustment: The entire surface of the strap can adhere, allowing users to adjust the tightness as needed for optimal pressure. Compared to traditional loop tourniquets with only a few fixed holes, it is much more convenient to use.
• Cleaning and hygiene: The material of hook and loop fasteners does not easily absorb water and is easier to clean and disinfect. It is environmentally friendly and reusable, which helps maintain the hygiene standards of medical supplies.

Based on the customer’s usage scenarios, the following processing options are available:

1. Appearance Processing: Rectangular, square, round, and special shapes can all be addressed with a practical solution from our consultants.

2. Special Functions:

• Self-adhesive Backing: A layer of adhesive is applied to the back of the hook & loop felt, allowing for bonding in situations where sewing is not feasible, such as with hard objects like glass and tiles. (Function x Self-adhesive Backing)
• High-Frequency Processing: For strong adhesion to PVC, a special adhesive layer is applied to connect the two materials. (Function x High-Frequency Processing)
• Flame Retardant Treatment: Designed for industries with higher safety requirements, such as automotive, aerospace, and military applications. (Function x Flame Retardant)
• Static Dissipation: Designed for the specific conductivity requirements of the electronics industry.

3. Binding and Fixing: For situations where items need to be bound together to prevent them from coming undone, or for marking functions. Closer to the end-user’s usage scenarios.

Some of these functions may conflict, while others are independent. Consult our sales team for the most reliable information.

Why Choose PA hook & loop fasteners Felt?

Compared to other materials, PA hook & loop excels in “softness”, “durability” and “cost balance”, making it the preferred material for most standard applications and particularly suitable for product designs that require long-term repeated use.
