Outdoor work in the rainy season in the south, how to balance waterproof and moisture permeability of jacket work clothes?

? From April to May every year, the south enters the continuous rainy season. For outdoor workers, the jacket overalls they wear are simply "second skin".

But many corporate purchasing executives have encountered such troubles: the jackets they bought are either waterproof but stuffy, and the inside will be soaked after wearing them for a while; or they are breathable, but after a heavy rain, the clothes inside are all wet. How to balance waterproof and moisture?

If this problem is not solved, employees will feel uncomfortable wearing clothes and their work efficiency will plummet.

To clarify the balance, we must first understand a core principle: water resistance and moisture permeability are essentially contradictory.

Waterproofing relies on the microporous film or coating on the surface of the fabric to prevent liquid water from entering. Moisture permeability relies on water vapor being discharged through the micropores. In theory, the smaller the micropores, the better the waterproofing, but the worse the moisture permeability. So the key to balance lies in "micropore size" and "fabric process".

The current mainstream solutions are PU membrane, TPU membrane and PTFE membrane.

PU membrane has low cost, good waterproof, but average moisture permeability. TPU membrane has good elasticity, environmental protection, and medium moisture permeability. PTFE membrane (also known as Gore-Tex) is very moisture-permeable and waterproof, but the price is high. For enterprises to purchase in bulk, the cost pressure is not small.

How to choose the southern rainy season?

The technical team of Shenzhen Yasenman Apparel Co., Ltd. gave a very practical suggestion: consider the intensity of the operation and the environment.

If it is a medium-to-low-intensity operation, such as inspection, logistics, and outdoor installation, it is enough to choose a jacket with TPU film + mesh lining. Waterproof above 5000mm, moisture permeability is about 3000g/m ²/24h, which is the most cost-effective, and employees will not be too stuffy to wear for a day.

If it is a high-intensity operation, such as power repair or building construction, then you must choose PTFE membrane or high-moisture-permeable PU membrane, with a moisture permeability of at least 5000g or more, and with an armpit breathable zipper, in order to truly achieve "heavy rain outside, no sweat inside".

In addition to the fabric, the process details also determine the balance effect.

For example, the rubber strip. In the rainy season in the south, there is a lot of rain, and the pinhole is not glued, so the water will seep into the suture. In the customization of jacket work clothes, all splices of Yasen Man clothing use a three-layer gluing process to ensure that the waterproof of the suture is not invalid.

Another example is the lining design. Some jackets have thickened linings to keep warm, resulting in a great reduction in moisture permeability. Yasenman's approach is: removable fleece liner + mesh liner. In the rainy season, a single shell has good moisture permeability. When cooling down, add a liner to keep warm, and wear more clothes to balance the needs of different seasons.

There are also necklines and cuffs. Velcro cuffs + stand-up collar design can prevent rainwater from pouring back, while not strangling the neck, ensuring comfort.

Finally, let's talk about an easily overlooked point: maintenance.

No matter how good the jacket work clothes are, if they are not cleaned properly, the waterproof and moisture permeability will be out of balance. It is recommended to wash them by hand with neutral detergent, do not wring them out, and dry them naturally. Regularly use professional waterproof spray to repair the water repellent layer on the surface.

Shenzhen Yasenman Apparel Co., Ltd. has been focusing on enterprise tooling customization for many years. For outdoor operation scenes in the southern rainy season, it provides a one-stop customization solution for jacket work clothes. From fabric selection, version design to pressing process, it can be adjusted according to the actual operating environment of the enterprise.

Don't pile on parameters, just look at the actual wearing effect. Let employees be dry outside and breathable inside in the rainy season, this is the real balance.

If your team is also worried about the rainy season tooling, it is advisable to start from the two sources of fabrics and craftsmanship to find the right balance.
