Background
Why self contained heated clothing?
Background
Negative effects from cold weather exposure
Hazards caused by temperature, winds, dampness, and cold water
Temporary solutions were not that helpful Multiple layers of clothing Chemical hand and feet warmers Reduce productivity
Background - Heat Loss
Alpine Education Guidebook Book2
Although there are outside factors acting on the body, the body itself loses heat. People turn to alternate solutions to retain body heat.
Alternate Solutions
Chemical heating: time frame safety issues non-controllable heat
Better insulation or more layers: already used same problems too bulky on occasions
Take frequent breaks: cuts down productivity not always an option
Criteria
SafeSelf containedEfficientAble to maintain a stable
temperature
Materials - Wool
Resists WrinklesResists soilingDurable Repels Moisture Retains ShapeResists Flames Wool is comfortable in all seasons
Materials – Nylon/Synthetic polymers
Is stronger yet weighs less than any other commonly used fiber.
It is elastic and resilient and responsive to heat setting.
Fibers are smooth, non-absorbent and dry quickly.
Dirt doesn’t cling to this smooth fiber nor is it weakened by chemicals and perspiration.
Extensive washing and drying in an automatic dryer can eventually cause piling.
Melts at high temperatures
Materials
Because of the durability of these fibers when incorporated in certain weaves they can be tear resistant and yet comfortable and cause little agitation.
Many other materials can be used to provide comfort for the wearer like elastic bands around the waist and at the cuffs. The suits can also contain padding or extra layering at areas of increased wear.
Insulation Material
Compared to other materials, like wool, fiberglass, polyurethane, and others, thinsulate is the best choice.
Thinsulate can control
the temperature held
within depending on the
thickness of the material.
Insulation
Ideal for trapping insulating and reflecting back the body’s heat.
It does not wear down, even after it is machine washed and/or dried.

Insulation
When thinsulate becomes wet, it still retains it’s strength and performance.
The material absorbs less then 1% of it’s weight in water therefore retaining it’s strength.

Future Research
Adapt many more sensors through out the jacket
Separate heating zones into many more strategic sections
Obtain stronger batteries to power more sensors and more heating coils.
Future Applications
The jacket will contain a heating and cooling system.
Heating and cooling pants will be available to accommodate the jacket.
Once the batteries are more advanced, cell phone and other chargers may be fitted into a pocket of the jacket or pants.
