Kool Wear
BEAT THE HEAT with a Kool Tie or Headband
Kool Wear is a very convenient and easy method of keeping cool during the summer heat.
Each Kool Tie incorporates super absorbent polymer crystals which are safe and non-toxic. Kool Ties work on the principal of evaporative cooling. Once the polymer is hydrated, the fabric surface of the Kool Tie draws the moisture from the polymer to the fabric surface, which evaporates resulting in an effective body cooler. When worn around the neck or head, the Kool Tie stays cool and moist for hours due to the polymer’s high amount of water-retaining properties. Brings great relief to the wearer in hot humid weather.
Science of Keeping "KOOL"
Evaporation of water is a very important means of heat loss. The latent heat of evaporation of water at normal body temperature is 0.58 kcal/g.
So with the evaporation of each gram of water from the body surface, the body loses 0.58 kcal of heat.
This water loss occurs mostly through sweating, but also through water that is breathed out or diffuses through the skin. The rate of evaporation depends on the relative humidity (RH) of the air, and only occurs when RH < 100% .
The application of a moist cloth, or in this case a bandanna or wristband that contains moisture holding polymers can assist in reducing the kcal/g of heat. The degree to which it is effective relates directly to both the ambient temperature as well as body temperature.
Kool Wear neck coolers are easy to prepare for use, easy to maintain while using them and can be washed for keeping good hygiene.
Non-toxic polymer granules often called crystals are concealed in the casing of a polyester filter fabric with an outer shell of cotton neck scarf. When the scarf is soaked in water the granules absorb the water, expand, and turn into a crystalline gel. The polymers release water through filter fabric due to osmotic pressure from the dryness of the surrounding environment and the cotton fabric absorbs the released water.
Materials in the Fabrication of Kool Wear
Super absorbent polymer, filter fabric, cotton fabric, thread, embellishments (beads, corporate logo, etc.), packaging materials.

Effect on Bodily Functions
Most body organs are most efficient at relatively constant body temperatures, near 37°C (98.6°F). The normal range of body temperature is from 35.5 to 40°C ( 96°F to 104°F). Beyond these boundaries, the human is susceptible to heat stroke (elevated temperature) or hypothermia, both of which are life threatening conditions.
Body temperature : For every increase of 0.5C in internal temperature of the body, the BMR increases by about 7 percent. The chemical reactions in the body actually occur more quickly at higher temperatures. So a patient with a fever of 42C (about 4C above normal) would have an increase of about 50 percent in BMR.
External temperature. Temperature outside the body also affects basal metabolic rate. Exposure to cold temperature causes an increase in the BMR. So as to create the extra heat needed to maintain the body's internal temperature, a short exposure to hot temperature has little effect on the body's metabolism as it is compensated mainly by increased heat loss.
Prolonged exposure to heat can raise BMR.An alert worker is a safer worker
Kool tie users experience less fatigue and are more aware of the job at hand • Will keep sun off their neck • Lowers perspiration rate • Reduces dehydration • Reduces stress from overheating • Cools the body and maintains blood flow to the brain • Allows clearer brain function • Helps reduce headache pain • Increases energy level
