How to buy clothes
Release time:2020-12-24
As we all know, the jacket is generally divided into soft shell (Softshell) and hard shell (Hardshell) two kinds. The so-called hard shell is generally worn as the outermost layer and plays a role in protecting wind, rain and snow. Some, such as ice climbing, snowy mountain climbing and professional exploration, often encounter extreme weather conditions, which requires that the clothing fabric should be durable, windproof, waterproof and breathable. Hard shell assault clothing is more suitable for professional outdoor sports. Generally speaking, the soft shell is a waterproof layer on the warm windproof fabric, which is more flexible and has good air circulation characteristics, but it can only be used for routine protection and is not suitable for use in polar environments.
1, waterproof index: waterproof index is an important policy to measure the waterproof function of fabric. Refers to the maximum water pressure that the fabric can withstand, in mmH2O. Taking the fabric with the waterproof index of 10000mmH2O as an example, under the pressure of 10000mm high water column, the water droplets seeping out of the fabric within 24 hours do not exceed 3 drops. The waterproof index is "5000mm", which means that the fabric can withstand a high water column pressure of 5000mm, which is equivalent to wearing the charge garment under heavy rain without getting wet.
2. Breathability index: Breathability index is an important policy to measure the breathability of fabrics. Refers to how many grams of water vapor can be transmitted per day in an area of one square meter, in g/m 2/24hr. Generally speaking, the air permeability index of a charge garment is above 3000 g/m 2/24hr and the water resistance index is above 5000mmH2O, which can ensure that the wearer will not get wet in heavy rain and satisfy the air permeability and moisture permeability during moderate exercise and perspiration.
3. Windproof: This policy seems to be compatible with the air permeability index, but in fact it is not. Many windstopper fabrics have achieved a good combination of windproof and air permeability. Personally, I feel that this policy is more suitable for soft shells and has little effect in the purchase of hard shells.
