The main differences between the injection-molded hook (plastic hook) and the nylon hook (traditional woven hook)

I. Technology and Structure (The Most Fundamental)
- Projected hook (one-piece injection molding): Nylon/PP granules are injection-molded to form a hook that is integrated with the base; the hook shape is neat and uniform, with high density (approximately 900 hooks per square inch) and extremely thin (the gap for engagement is about 1mm).
- Nylon hook (traditional weaving): Nylon single filaments are woven into a loop → cut into hooks; the base is a fabric band, and the edge can easily release the yarn; the hooks are arranged sparsely and have a thick engagement (about 2–3mm).
II. Key Performance Comparison
- Tensile strength: The lateral pulling force of the ejected hook is stronger (≥ 1000g/cm²) and the peeling force is stable; the nylon hook has a weaker pulling force and is prone to deformation.
- Durability: The ejected hook is fatigue-resistant and has a long lifespan (good performance retention after 3000 cycles); the nylon hook is prone to breaking and falling off when repeatedly opened and closed.
- Appearance and feel: The ejected hook is ultra-thin and soft, making it easy not to hook the yarn, and has good sewing texture; the nylon hook is relatively thick and hard, and is prone to damaging the fabric.
- Processability: The ejected hook can be high-frequency pressed, without sewing, and can be cut in irregular shapes; the nylon hook can only be sewn and the edge trimming is rough.
- Materials: The ejected hook is commonly made of nylon/PP; the nylon hook is woven from pure nylon.
III. Applicable Scenarios
- Hooked Out: High-end shoes and clothing, sports protective gear, medical supplies, car interiors, infant products (ultra-thin, non-irritating to skin, not prone to falling off).
- Nylon Hooks: Ordinary clothing, backpacks, tents, home textiles (low cost, suitable for regular light to moderate use).
IV. One-sentence Summary
Ejection hook = Injection molding integration + Ultra-thin and strong pull + Durable and exquisite + High-end application;
Nylon hook = Woven tradition + Thick and soft average + Easy to remove threads + Low cost and wide application.
