Fantastic X-Static! - I

It is somewhat humbling to know that a Persian King touted the benefits of the active ingredient used in X-Static. X-static offers all of the benefits known to be inherent to pure silver, only in a new format - a textile fibre

The use of silver for its medical and therapeutic benefits dates back thousands of years. In fact, the Romans were the first to publish and document in “magical healing” powers of silver when used to cover wounds. Further, Cyrus the Great, in the 5th century BC, would only let his troops go to war if they carried water in silver vessels - something he knew would keep the water supply clean and safe.

Roman intuition proved to be correct. Modern Western medicine recognizes silver as the most effective antimicrobial agent, natural or otherwise. Today, silver is used for its broad-spectrum antimicrobial properties in healthcare products ranging from bandages to burn care treatments to catheters - almost any product where infection control is critical. The majority of Americans are first exposed to silver at birth, when silver nitrate eye drops are used to prevent infection. Silver is also widely used for industrial applications, most notably in drinking water filters and swimming pool filtration systems.

X-Static - The silver fiber

X-Static - The silver fiber, has a layer of pure silver permanently bonded to the surface of a textile fiber. The process is such that the fiber, with its silver layer, retains traditional textile and tactile characteristics. It can be used in knits, wovens and non-wovens as either a filament or spun yarn. X-static offers all of the benefits known to be inherent to pure silver, only in a new format - a textile fiber.

X-Static has been used primarily as an industrial and medical product for the last decade, servicing high-tech industries and the Department of Defense. More recently, however, X-Static has been thrust into consumer product markets as a result of the need for a safe and effective antimicrobial solution. X-Static is the best antimicrobial solution on the market, yet it is a fiber system that is uniquely suited to meet several additional market demands:

1. Antimicrobial: Eliminates odor-causing bacteria and athlete’s foot fungus.

2. All natural: Safe and non-toxic, containing no chemicals or pesticides.

3. Heat transfer: Cooler in the summer, warmer in the winter.

4. Anti-static.

5. Therapeutic: With its conductive properties (silver is the most conductive metal), the fiber system has many health benefits.

X-Static has been researched and tested by leading institutions around the world and is widely accepted in the medical community. X-static is used in many FDA approved products and is also registered as an antimicrobial with the EPA. The X-Static brand is growing rapidly in the worldwide consumer marketplace and X-Static products have won prestigious awards for outstanding performance and function.

ANTIMICROBIAL PERFORMANCE

The antimicrobial performance of X-Static has been validated by prestigious institutions throughout the world. In addition to independent laboratory and field tests, X-Static was the focus of numerous medical abstracts published over the past several years. A synopsis of these studies has been included in this document - all show that X-Static provides unparalleled antibacterial performance. Several studies prove that when someone wears an X-Static product, the fiber is so effective that sweat actually becomes antimicrobial. When you compare X-Static to other antimicrobial products, there are several distinct performance advantages:

  • Speed: X-Static eliminates 99.9 per cent of bacteria in less than one hour of exposure. (Most antimicrobial products test over 48 hours and still do not reach this level of effectiveness).
  • Catalysts: The hotter and wetter the environment, the more effective X-Static becomes. This is perfect, because bcteria are more prevalent in these environments.
  • Safe and natural: X-Static is made with pure silver, a naturally occuring element. There are no chemicals and there is no fear of toxicity for the consumer. Silver is one of the safest and most benign substances to mammals. (The use of chemical antimicrobial products has been clouded by fears of harmful side effects).
  • Permanent: X-Static is not a surface treatment. Silver is irreversibly bound to a polymer so it becomes a physical part of the fiber. X-St atic is permanent and performance does not diminish over time. In fact, X-Static has been tested for more than 250 washes with virtually no reduction in antibacterial performance.

ANTI-ODOR PERFORMANCE

Antimicrobial is not always synonymous with anti-odor. X-Static offers both antimicrobial and anti-odor performance.

Bacteria are only one cause of body odor. Ammonia and denatured proteins are also significant contributors to odor in apparel and hosiery products. Incredibly, both ammonia and denatured proteins bind most readily to silver. Because silver is on the outside of the fiber, X-Static allows for immediate binding with ammonia and denatured proteins - resulting in instant odor reduction.

HEAT TRANSFER

The biophysics of clothing has become an area of significant interest in recent years. It represents the marriage of physiology, physics, textile science and clothing design. The specific area of thermal performance has been the primary focus of this burgeoning area of study. Given the proper materials and constructions, it is now possible to use the existing energy of the body and the environment to actively regulate temperature through heat transfer. Because of the inherent properties of silver, X-Static is perfectly suited to this task.

Body heat is transferred by four basic mechanisms:

1. Radiation - the primary heat transfer mechanism in cold weather, contributing to approximately 90 per cent of body heat loss. (In warm weather, heat loss due to radiation will be very low or none). In order to increase body temperature in cold weather, it is critical to actively use the radiative energy generated by the body. The most efficient means of using this energy is to reflect it back to its source and/or to store it.

2. Conduction - the primary heat transfer mechanism in warm weather (because radiation contributes to little or no heat transfer). In order to transfer heat and reduce body temperature, it is necessary to actively move, or conduct, heat from the skin to the outside environment.

3. Evaporation - the change of a liquid into a gas. When the body can’t dissipate enough heat through conduction or convection, it will use evaporation, the result of which is sweat. Evaporation is active in warm and cold weather, depending on activity levels. In order tomain comfortable, the moisture generated by the body must be transported efficiently away from the skin

4. Convection - the movement of heat between a solid and a liquid or gas. Convection is noticeable in cold and warm weather. For example, wind will cool your skin, making you more comfortable in hot weather and less comfortable in cold weather. Convective heat transfer can be discouraged or encouraged by using or not using insulation and wind barriers.
