By combining modern textile technology with traditional Chinese medicine, supported by scientific studies, Back on Track creates products that help people, pets, and horses achieve a more active and comfortable life.

Welltex technology is a state-of-the-art textile technology found exclusively in Back on Track products. This technology uses a proprietary ceramic and mineral solution that reflects body heat as long-wave radiation, also known as far infrared radiation.

Research shows far infrared radiation has multiple benefits for humans and animals, and studies demonstrate wearing Back on Track products can produce these positive effects.

Body Heat and Energy Transfer

People and animals emit body heat, both at rest and during activity. Heat is a form of energy that can be transported in three ways: conduction, convection, or radiation.

Conduction

Conduction is the direct transfer of heat or energy between adjoining regions. Heat in a material spreads from one part to another. For example, a pot of water boils when heat transfers from the flame to the pot and the pot to the water.

Convection

Convection is the loss of heat when a heated liquid or gas is displaced, carrying the heat with it. Insulating clothing materials such as cotton, wool, and neoprene are designed to prevent convection and thus retain body heat in the air outside the skin.

Radiation

Radiation occurs when a source emits energy as electromagnetic waves that collide with another surface and heat it. The distance between these waves determines the wavelength of radiation.

All people and animals emit thermal radiation. Back on Track’s products work with this radiant warmth. Materials that don't depend on heat trapped through insulation maintain breathability while harnessing body energy.

Textile Technology

Textile technology uses scientific principles to design, produce, and apply materials for specific purposes. Engineers select the materials used in textile technologies based on their chemical and physical properties, which create the desired effect in the final product.

One important aspect of textile technology is how materials interact with radiation waves. Materials can transmit, reflect, or absorb radiant warmth. Different materials have a unique absorption and emission spectrum depending on the wavelength of the radiation.

Transmittance

Radiation waves can pass straight through the material, which is called transmittance. An example is when the sun’s heat rays hit a glass plate. The majority of the heat radiation passes through the glass. You would feel this effect if you were to stand in a room with the sun shining through the window.

Reflection

Some materials reflect radiant heat. Radiation waves bounce off the surface of the material and are reflected away. If all the heat is reflected, the material will not be heated as none of the rays radiate through it. However, no materials reflect all heat, only specific wavelengths.

Absorption

The material can also absorb heat radiant waves. Absorption transforms radiation into another type of energy, usually heat. Absorbing radiation increases the material's heat content.

Materials absorb different amounts of heat radiation depending on the wavelength of the radiation. This is called the material’s absorption spectrum.

Emission

An emission spectrum is the spectrum of wavelengths emitted by a material. Different materials radiate heat of various wavelengths at different temperatures.

The amount of radiation and the wavelength of the radiation varies depending on the heat source temperature and the emission spectrum of the heat source materials.

How Welltex Technology Works

Welltex is a textile technology by Back on Track that reflects radiant body heat as far infrared radiation. The technology uses the reflective properties and emission spectrum of ceramic particles in a proprietary solution found exclusively in Back on Track products.

Far Infrared Radiation

Radiation has different wavelengths depending on the temperature and source. The wavelength is the distance between individual radiation waves. Radiant heat is usually within the range of infrared radiation, which includes electromagnetic wavelengths between 760 nm and 1 mm.

Infrared radiation has a longer wavelength than visible light. Far infrared radiation (FIR) is the longest wavelength on the infrared spectrum. This type of radiation effectively transfers energy because many materials absorb far infrared radiation. ^[1]

Ceramic Textiles

Modern science revealed the ancient Chinese practice of using marble on sore muscles relieved pain because ceramics contain minerals that emit far infrared radiation at specific temperatures. When ceramic particles absorb the body’s heat, they reflect that energy as far infrared radiation.^[1]

Ceramic particles are fused into the fibers of textiles used to make Back on Track products. However, not all ceramic products emit the same amount of far infrared radiation.

What Makes Welltex Different

Welltex is a state-of-the-art technology that uses a proprietary ceramic and mineral solution to create the strongest far infrared radiation effect. The ceramic particles and minerals used in Welltex fabrics are selected based on their absorption and emission spectrum.

The most significant effects from far infrared radiation result from textile technologies with the highest emissivity value, which measures an object's ability to emit infrared energy as radiation.

Haematex and Iontex

Haematex and Iontex are versions of Welltex technology optimized for certain activities. Iontex offers flexibility, while Haematex provides high elasticity and light support.

Benefits of Far Infrared Radiation

Research shows far infrared radiation can benefit animals and people due to several physiological effects. Like other materials, the body’s tissues have their own absorption spectrum. Far infrared radiation can penetrate body tissues more deeply than other wavelengths.^[2]

Increased Circulation

Studies show exposure to far infrared radiation increases nitric oxide levels in body tissues. Nitric oxide is a critical chemical messenger in the body. Increased nitric oxide causes vasodilation, which widens blood vessels and increases blood flow.^[2]

Healthy circulation is essential for delivering oxygen and nutrients to tissues throughout the body. These effects support recovery and healing while reducing inflammation and pain.

Injury Prevention

In addition to increasing circulation, nitric oxide can activate other molecules in the body that aid muscle relaxation. Relaxation reduces muscle fatigue, while tight muscles can contribute to injuries caused by imbalances and increased strain.^[2]

Reduced Recovery Time

Some studies linked far infrared radiation to increased rates of healing due to bio-stimulation. Researchers in the studies found that exposure to FIR increased several biological processes involved in healing injuries, including growth factor production and collagen synthesis.^[3]
