The difference between a cold-proof suit and a jacket is that both have the function of cold-proofing, but they correspond to the working environment and the time accepted is different.
The fabric of jackets is generally divided into the outermost maintenance layer, the center waterproof and breathable layer and the lining.
The maintenance layer and the waterproof and breathable layer are pressed together, and the lining is separated from them, usually nylon silk, mesh cloth or some kind of sweat-absorbing material, mostly black. The rubber strip at the seam is blocked by the lining and cannot be seen (unless it is through the mesh).
Three-layer fabric: the maintenance layer, the waterproof and breathable layer and the lining are pressed together, which looks like a layer of fabric, and the general lining color is mostly silver gray. You can see the rubber strips at the seams of the lining. Generally speaking, the breathability and warmth of the two-layer fabric is slightly better than that of the three-layer fabric, but the three-layer fabric is lighter in weight, comfortable to wear (the second layer is a bit wacky), and the folding volume is small (the jackets of spring, summer and autumn are mostly put In the bag). So unless you only consider using it in winter or snowy mountains, it is generally better to choose a three-layer fabric.
There are two main types of jackets:
(1) One kind is ePTFE laminated microporous fabric. At present, most of them are GORE-TEX, DENTIK, EVENT, 3TO1-TEX in China. Its waterproof and breathable function is to compound a layer of microporous film on the outer fabric of the garment. The micropores in between are smaller than water droplets and larger than gas molecules, which can evaporate their own sweat while blocking rain.
(2) The other is a hydrophilic fabric coated with PU or TPU (or laminated). Its function is achieved by a non-porous waterproof layer and a hydrophilic molecular chain structure.
The difference between winter clothes and jackets
Winter clothes, tops with warm materials such as cotton lining. The style is not restricted. The finished cold-proof clothing is actually stitched together two parts of the cold-proof clothing-the inner part is cold-proof, and the outer part acts as a windshield. The inner layer mainly uses a layer of nylon fabric, and then adds the key ingredients: a film that stabilizes and maintains the heat insulation material, plus a thick layer of polyester thermal insulation material. At this time, the warmth layer is larger than the fabric-this ensures that every part of the jacket is warm.
The outer fabric of the cold-proof clothing is generally made of thick nylon fabric. The fabric is a special fabric with some small holes on it. The moisture in the clothes can pass through these small holes and prevent water droplets and wind from penetrating in. The zipper is Made of corrosion-resistant nylon, the life of the nickel-plated zipper slider is 7 times longer than that of the ordinary zipper slider. Before this process, the workers mainly choose the craft from inside to outside. Now they want to turn over the winter clothes for final processing. These large snaps are strong and strong. They are located between the fiber materials, so they will not damage the fabric if they are reused. Its secret is the hidden warm layer. It makes the air stay in the surface of the human body, and then heats it up, creating a kind of heating mat that resists the severe winter cold. Generally, it is composed of thermal insulation layer, windshield layer and thick nylon.
