Which fabric is best for you depends on your application. We stay current with newly emerging technologies and keep up with the any new finishes and additional fibers that continue to be developed to address any potential shortcomings in the global market place. Of course, budget is the first thing to be cared about as well as comfort and enough protection for your employees. There is a balance to be well calculated between these two factors. Secondly, work wear must withstand the abrasion of everyday, especially for outdoor work wear. Traditional work wear fabric choice: cotton and polyester 100% cotton is a fully breathable fabric, which means that it can be cooler to wear in hot conditions. However, as the thickness increases, the breathability decreases. 100% cotton tends to rip and wear out easily, depending on the weave. Among them, cotton canvas is a very durable and abrasion-resistant fabricPolyester does not breathe and has a tendency to stick to the skin once perspiration begins. In regard to durability, polyester is a more elastic fiber and therefore tends to be tear resistant. And it is usually considerably cheaper than 100% cotton. Poly cotton blends are breathable, tear-resistant, and can be fashioned into abrasion-resistant fabrics, like canvas. And they do tend to cost less than comparable garments made of 100% cotton while providing much more comfort. 65/35 blend of cotton and polyester is the most popular for work garments. If employees work indoors around machinery, the tear-resistance of poly cotton may be favorable. If the work is in an outdoor setting, particularly in hot climates, 100% cotton fabric could be the better choice. Before deciding, make sure to take all environmental factors into consideration. Cooling Technology Up to now, there are many brands of cooling technology for polyester fabric. There are generally two kinds: fiber-built-in and post-processing with chemicals. With fiber-built-in cooling tech such as coolmax，cooldry，cool-T, with special architecture of fiber the polyester material shows unique cooling performance than cotton. They are proven to dry faster than other performance fabrics, and considerably faster then cotton. HERE'S WHY: ---Unique engineered fibers quickly move moisture to the outer surface of the fabric. ---Larger surface area of fibers allows for faster evaporation. ---More open fabric yarn structure provides outstanding breathability. Comparing with chemical post-processing the fiber-built-in tech enjoys permanent cooling feature, while the fabric of chemical treatment will lose the cooling feature when washed out over time. Of course, fiber-built-in fabric is much more expensive than chemical treatment. Wearing these polyester fabric will give you excellent dry touch with breath and cool effect. Flame Retardant Technology Understanding the basic differences between "inherent" and "treated" flame resistant technologies is very important for those responsible for evaluating, selecting, and wearing flame resistant garments. Blended fabrics, which contain blends of treated and inherently flame resistant fibers, attempt to balance the strength and weaknesses of each fiber type. In inherently flame-resistant fabrics, flame resistance is an essential characteristic of the fiber from the textile is made. Because the actual structure of the fiber itself is not flammable, the protection it affords is permanent, it can never be worn away or washed out. When exposed to flame, inherently flame resistant fiber swells and becomes thicker, forming protective barrier between the heat source and the skin. This protective barrier stays supple until it cools, giving the wearer vital extra seconds of protection to escape. Treated fabrics are treated with a flame retardant chemical to make them flame-resistant. The fibers used in these fabrics, such as cotton, are not normally considered protective and become flame-resistant because of the treatment. The durability of the treatment can vary from very limited life to the life of the garment. Unlike fabrics made with inherently flame resistant fibers, chemically treated flame resistant fabrics may have their flame resistant properties diminished or removed completely depending on how these fabrics are laundered and/or which chemicals they are exposed to in the work environment. However, fabrics made from treated synthetic fibers-which are extruded with a flame retardant chemical in the fiber-forming process-become flame-resistant for the life of the garment because the flame retardant cannot be removed by wear of laundering. ---Nomex? IIIA by DuPont, a blend of 93% Nomex?, 5% Kevlar? and 2% static dissipative fiber, is an inherently fiber-flame-resistant fabric and provides excellent protection from fire and arc flash hazards. The lightweight, durable fabric resists abrasion, tears and chemicals, lasting three to five times longer than other standard and protective fibers. ---Chemical Treated FR techs have many brands, as Proban, Pyrovatex，protex and etc.. The fabric can be divided into mainly two categories: fiber treated and fabric treated. Comparing with Nomex, it is cheaper but its FR performance varies from 60 washes to lifetime of the garments according to different processing methods.
