Earloop usually referred to in the field of masks as ear hanging wires, are important components used to fix masks to the ears of the wearer.
I. Types,Elastic ear line
Advantages: It has good elasticity, can adapt to the wearer of different head and face shapes, is more comfortable to wear, and is not easy to produce scratches. After stretching, it can be easily hung on the ear, convenient and quick.Disadvantages: Elasticity may be weakened after prolonged use.
Inelastic ear line,Advantages: more durable, not easy to deform. The length can be adjusted according to the needs, suitable for different wearing needs.
Disadvantages: For some people with a larger head or a wider face, it may feel tighter and less comfortable to wear.
Second, material,Spandex material
Features: Spandex has the characteristics of high elasticity, not easy to deform, and is often used to make elastic ear wire. Its tensile recovery performance is good, and it can ensure the stability of the mask to a certain extent. At the same time, spandex material is soft and skin-friendly, less irritating to the skin.
Polyamide material,Features: Nylon has high strength and wear resistance, suitable for making non-elastic ear wire. It also has good corrosion resistance and can maintain good performance in different environments. Nylon ear lines are usually smooth, and it is not easy to produce friction when wearing.
3. Production process,Weaving technology
For some elastic ear wire, it is usually made by braiding process. The elastic fiber such as spandex is braided through the braiding machine to form the ear line with certain elasticity. The weaving process can make the structure of the ear wire tighter, improving its strength and durability.
Injection molding process
Inelastic ear wires can be produced by injection molding. The plastic particles such as polyamide are heated and melted and injected into the mold to form the ear line with the required shape. The injection molding process can achieve large-scale production, and the dimensional accuracy of the product is high.
Fourth, quality requirements,Strength requirement
The ear line should have enough strength to withstand the tension of the mask during wearing, and it is not easy to break. Especially in some occasions that require frequent removal and wearing of masks, the strength of the ear line is particularly important.
Comfort requirement,The ear line should be soft and comfortable, and will not cause discomfort when in contact with the skin. For elastic ear lines, avoid being too tight or too loose, so as not to affect the wearing experience. The length of the inelastic ear line should be moderate to meet the needs of different wearers.
Environmental protection requirement
The material of ear wire should meet environmental protection standards, non-toxic and tasteless, and harmless to human health. In the production process, the pollution to the environment should be minimized.
5. Application fields,Ear wires are widely used in various types of masks, including medical masks, civil masks, industrial protective masks, etc. Different types of masks can choose the appropriate ear line material and type according to their use scenarios and needs.
