Which is stronger for safety vests, Velcro or zips?

Zips are usually more reliable than Velcro when it comes to firmness.

1. How to use Velcro and zips
Velcro and zips are both common closures for Safety Vests. Velcro usually requires the wearer to stick the two together directly, while zip requires the wearer to slide the zip bar up or down along the teeth of the zip chain to open or close the zip.

2. Structural principles of Velcro and zips
Velcro usually consists of two main parts, i.e. the velour and the hook. The velvet and the hooked hairs are able to intertwine with each other to form a strong structure when they are bonded. Zips are usually made up of two main parts, the teeth and the slider. When the slider moves along the teeth of the zip chain, the gap between the teeth and the slider is filled, forming a structure that can be firmly closed.

3. Influence of material on the firmness
The firmness of Velcro and zips is also affected by different materials. Velcro is usually made of nylon, synthetic fibres, etc., in which the harder hooked hair can be better bonded and remain stable. Zips are usually made of plastic or metal, of which metal zips have higher abrasion resistance and firmness.

4. a comprehensive assessment of the degree of firmness

Although Velcro sounds convenient, after a period of time, the long fluff is easily deformed and loses its adhesion, thus affecting the sealing effect. Zips, on the other hand, are more reliable than Velcro and can better protect items from external interference. Therefore, in the case of high requirements for firmness, it is recommended to use zips.

To sum up, although both Velcro and zips have their characteristics, zips are usually more reliable in terms of firmness. Whether it is in bags and cases that need to be sealed in daily life, or in products that need to be sealed strictly in the professional field, zips can bring us better protection.
