WHY BREATHABILITY IS A BIG PROBLEM? The above summary shows problems and reasons of main sports bras. Among these, body sweating is the main problem.by using breathable materials excess moisture can reduces for some level. BREATHABILITY Garment Breathability is the process that moving air in and out through the garment (Textile center of excellence, 2017). in sport wear products, breathability is one of the most important key factor for increasing performance. Furthermore, sport market major driving force behind the development of new breathable fabric. We are engaging with sports activities water vapor will build up inside the garment and moisture condense on the inside surface on the wearer’s inner clothing. So, it’s discomfort to the …show more content…
Maintaining air circulation between the wearer and garment layer is more important to heat and moisture from the body Above figure 5/6 show how moisture vapors transition mechanism from skin to atmosphere through fabric. A garment can be become a breathable by using breathable fabrications. Also by garment construction. Also, breathable fabrics quickly absorb sweat speedily spreading it. It’s a main factor in breathable fabrics (shashi, 2017). Several techniques of breathable fabrics - Closely woven fabric - Microporous membranes & coatings - Hydrophilic membranes & coating - Combination of microporous & hydrophilic membrane & coating - Smart breathable fabric - Fabric based on bio mimetics (Choi, 1999). By using hydrophilic and microporous materials can allowtransmission of water vapor. Also, from garment constructions can achieve the breathability by adding ventilation panels(Choi, 1999). HOW A FABRIC OR GARMENT BECOME LOW-BREATHABLE AND IMPACTED OF LOW BREATHABILITY A material which prevents the passing of water vapor through it, is called as low-breathable. Several types of reasons can affect for the garments to become
In 1996 Kevin plank, the founder of Under Armour came up with the idea of moisture wicking fabric for shirts so that while playing sports you don't have to wear a sweat soaked shirt during the game. He gave the prototype shirt to a couple of his friends on the University Of Maryland’s football team to test and see if the shirt kept them dry,cool, and felt lightweight. As soon as the microfiber shirt was released Nike began to produce a similar shirt to compete with Under Armour,but it was too late, the Under ...

Regulation- Blood vessels help maintain a stable body temperature by controlling the blood flow to the surface of the skin (Terfera, David, and Jegtvi)
Elizabeth Forward High School is situated on top of hill with very little shade, leaving it vulnerable to the heat in the summer months and freezing temperatures in the winter months. The school’s brick construction traps the heat in the summer, and the poor air circulation and air conditioning units limited to computer rooms and administrative offices makes it hard for the building to cool down. Unfortunately, one of Elizabeth Forward’s more strict policies prohibits students from wearing tank tops; students must wear some type of sweater that covers their shoulders if ...
Before even exploring the internet, quite a lot of time was taken to figure out the topic for this report. Once the topic was selected, several questions and ideas were noted to research about. The University of Waterloo libraries online database was used to search for reliable sources for articles. PubMed and Google Scholar were selected as the primary sources for articles, as well as reliable and valid individual author websites. After short listing several articles related to the topic, each article was carefully read and evaluated for validity, reliability, and overall quality. After analyzing and interpreting the data of the articles, the selected topic of this report will be further explained. Three main articles were selected from three very respected journal including, Journal of Science and Medicine in Sport, Journal of Strength and Conditioning Research, and Fitness & Performance Journal. In order to increase experimental control as well as external validity, the articles chosen experimented in outdoors conditions which are exposed to climate conditions, as well as indoors on rubberized to minimize climate conditions (1*). References were later cited to give credit to the original author(s) of the articles.

One very important factor to look at when prepare to train in cold weather is attire. It is important to dress for the weather conditions, but it is even more vital that participants not over dress. The most common misconception when it comes to dressing for cold weather is that more is best. It is dangerously wrong to over dressing for the cold. Excessive clothing during weather exposure can lead to injuries ve...

The air in between the layers of glass should be thick and dense, so that it can save energy. One of the most common airs used in-between glass is argon. When argon is used heat loss is reduced. You could also use carbon dioxide or sulfur hexa-fluoride between glass.

The rate of evaporation can increase if the gas pressure decreases around the liquid. Heat energy is used to break the bonds that hold water molecules together, that is why water easily evaporates at the boiling point but evaporates much slower at the freezing point. Net evaporation happens when the rate of evaporation surpasses the amount of condensation. Saturation occurs when these two process rates are equivalent when the humidity of the air is at one-hundred percent. On average, a fraction of the atoms in a glass of water has enough heat energy to escape from the liquid. Evaporation from the ocean is the primary device for supporting the surface-to-atmosphere part of the water cycle. Evaporation is the pathway where water moves from the liquid state back into the water cycle as atmospheric vapor. Studies have shown that the major bodies of water are nearly ninety percent of the moisture in the atmosphere from the evaporation of the water, the ten percent left is contributed from plant transpiration. Evaporation can only occur when water is available. It also requires the humidity of the surrounding atmosphere to be less than the evaporating surface. At one-hundred percent relative humidity, there is no more evaporation. The wind chill effect is one of the
furnaces. By letting all these gases release into the air, it makes it harder to breathe.
In mammals. the skin excretes sweat through sweat glands throughout the body. The sweat, helped by salt, evaporates and helps to keep the body cool when it is warm. In amphibians, the lungs are very simple, and they lack the necessary means to the exhale like other tetrapods can. The moist, scale-less skin is therefore essential in helping to rid the blood of carbon dioxide, and also allows for urea to be expelled through diffusion when
According to the utilization of space between body and clothes, clothes can be either passive or active in its practical
As air humidity is in an instance of increasing, its ability to absorb water vapor decreases and evaporation rate slows down. For evaporation to undergo there must be a difference in humidity (Tenalem Ayenew and Tamiru Alemayehu, 2001; Fetter C.W, 1994).
From 2005 the textile segment has been made up of 2 companies, transforming raw materials into fabrics, from spinning to finishing and ennobling. Handicraft product quality and technological research development characterize this business segment which works with internationally recognized names of the apparel and fashion industry.
