What's Merino Wool and how does it make a difference in everyday life? It's the heart and soul of every SmartWool productl; it's natures finest Merino Wool. Used properly, we think it's the best fiber available for outdoor apparel — manages moisture better than cotton, smarter than synthetics and more comfortable in any weather condition. In our hands, it becomes extraordinary.
Wool fiber is a complex structure that, believe it or not, behaves remarkably similar to our skin; naturally cooling and heating as the body needs.Predominantly made of interlocking protein molecules known as keratin, the same protein present in our own skin and hair, individual wool fibers have the ability to be bent, flexed and stretched in any direction 30,000 times or more without damage. Now that's one strong fiber!In addition, wool fibers have a natural curl called the "fiber crimp" which improves the elasticity and over all resilience of the fiber.
Because of wool's ability to effectively manage moisture, odor-causing bacteria don't have the moist environment they need to thrive. You can wear wool during intense activity and over extended periods of time without having to worry about odor.
Wool is a natural dirt repellent, too. The scales and crimp that give wool its shape also prevent dirt from penetrating the fiber surface. And, because these fibers are naturally static resistant as well, they're less likely to attract dust and lint.
Keratin, the same protein that gives wool its great elasticity and strength, is also responsible for wool being a natural water repellent. It's able to shed away small quantities of moisture from its surface with ease
Wool's ability to retain moisture is also responsible for its static resistance. The retention of moisture within the fiber prevents a build-up of static electricity and the spark or "cling" associated
with it.This feature is especially important in safety areas where it's necessary to prevent sparking.
Wool is a very durable natural fiber. The interlocking protein molecules within individual wool fibers have the power to elongate, stretch and recover, creating an extremely strong and resilient fabric that resists degradation over years of use and abuse.
Wool is infamous for being an itchy fabric. Merino wool however, is a different story.The "itchiness" people associate with wool is determined by the diameter of the fibers used. Larger, broader fibers are less flexible and have less ability to bend, which results in a prick when pressed against the skin, causing the sensation of itch.Merino wool is able to ditch the itch thanks to its fiber's smaller diameter, or being "finer". These fibers are more flexible and softly bend when pressed against the skin and, therefore, don't itch like other wool.These finer fibers also enhance wool's elastic nature, making garments made with Merino wool more able to conform to the shape of the body they're on, enhancing the garment's performance and the wearer's comfort.
The drying time of a fabric is controlled by two factors: 1) the amount of liquid moisture held between the fiber matrix when it starts to dry and 2) the humidity and temperature of the surrounding atmosphere.Generally, the thicker the fabric, the more moisture it's able to retain and the longer it takes to dry. Our fine-spun Merino wool fabrics dry as quickly as any performance synthetic fabric of comparable weight.
SPF and UPF are often thought of similarly. UPF stands for UV Protection Factor and is a measurable of how much UV light a fabric blocks. In a paper first published in BMC Dermatology 2001, Consultant Dermatologist Dr. Thilo Gambichler investigated 236 apparel textiles used in spring and summer clothing collections.Only one textile in the study had all its samples pass the test,
and that was Merino wool. In fact, Merino's poorest sample produced a result of UPF 40+, while more than 70% of the Merino samples had a UPF 50+.
Merino wool has hygroscopic characteristics that allow it to absorb and release moisture from the air. The movement of moisture through wool fabrics is controlled by the difference in the moisture content of the air between the skin and the fabric and the moisture content of the fabric itself.Wool "breathes" by maintaining the equilibrium of moisture between itself and the surrounding environment. Its fibers constantly absorb or release moisture from one environment (such as inside your shirt during exercise) to another (outside your shirt).
Wool fibers move this moisture while it's still in a gaseous form. Meaning, as your body heats up, the moisture vapors will be absorbed by the wool fiber, and released to the drier environment outside of the fabric; releasing heat and keeping the wearer dry and comfortable.A Merino fiber can absorb and retain up to 35% of its own weight in moisture and still feel dry to the touch.
Wool doesn't absorb moisture like a sponge, which is a mechanical process similar to holding water in a bucket. Instead, wool absorbs and releases moisture through a natural chemical process. Water molecules actually bond to the protein molecules that make up the wool fiber.When wool undergoes moisture absorption, negatively charged oxygen atoms in the water vapor molecule are attracted to the positively charged hydrogen atom in the wool's protein backbone. This is called bonding, or what chemists refer to as polar covalent bonding.
Also, as wool absorbs moisture, a bond is established between the atoms, and as a result, energy is released in the form of heat. This is one reason wool does such a good job keeping you warm while you're exerting yourself in cold weather.Conversely, it takes energy to break that same bond, so as wool releases moisture to a drier environment, it is absorbing heat from its surroundings, creating a natural cooling effect. This is why wool robes keep you comfortable in the heat of the desert.
You know how wool moves moisture vapor before it turns to sweat. But, what happens when we perspire faster than the vapor can be transported? At this point, wool will move liquid mechanically, just like synthetics do...Both synthetics and wool have the ability to wick, but only wool has the ability to wick away moisture in its vapor state.
