What are the best clothe material for the tropic climate? October 20 2014

High temperatures combined with high humidity (these are characteristics of our tropical climate) can make life uncomfortable, and because fashion is basically supposed to be comfortable be fitting. Humans keep cool mainly by sweating: the evaporation of liquid takes heat away from the body. Sweat evaporates less quickly when humidity is high, and so has less of a cooling effect. For this reason, fabrics for tropical climates should maximize the flow of air through the clothing, allowing heat and moist air to escape. It also helps if clothing is loose fitting.

Some fabrics tend to trap heat by providing an insulating layer over the skin. Others tend to reflect heat back to the body and inhibit the outward flow of warm, moist air; this is often true of synthetic fibers, such as polyester. Another important factor is the ability of a material to absorb water. Synthetic fibers tend to be water-repellent; they allow sweat to build up, reducing evaporation, and causing discomfort and irritation. Natural fibers are generally better at soaking up moisture from the skin and allowing it to evaporate from the outer surface.

As a general rule, the best fabrics for tropical climates are those made from natural materials such as cotton, linen and rayon. Strictly speaking, rayon is a semi-synthetic fiber, but it is made from natural raw materials and resembles natural fibers in its properties. These materials tend to “breathe” more than synthetics such as polyester. Wool and silk are not good choices, as they tend to retain heat, and silk can lose some of its strength through exposure to strong sunlight and perspiration.

 

Cotton is an excellent material for a tropical climate because it permits movement of air from the skin through the fabric, allowing heat to dissipate and reducing humidity. It also absorbs moisture well, keeping the skin dry and increasing evaporation. This tendency to soak up water could potentially also be a problem: it can become damp and stay damp for some time. Anyone who has worn denim cotton jeans in wet weather will know that they absorb a lot of water and take a long time to dry out. These, however, are made of relatively coarse, thick material; cotton clothing for hot, humid parts of the world should be made of thinner, lighter fabric.

Another useful property of cotton is that it can be machine washed and dried. As sweat accumulates in a hot climate, the ability to wash clothing quickly and easily is a definite advantage. Cotton is also easily ironed and reasonably durable.
