What about polyester fabric? How about air permeability?
Polyester fiber generally refers to polyester fiber, fabric quality is the result of comprehensive performance, as outlined below, your question is only the last line to answer, but I think you need to know something:The main physical and chemical properties of polyester fiber1. form: Polyester vertical surface straight, smooth, cross section is round (can be changed to special-shaped, such as triangle, hexagon, etc.). Polyester acid and not alkali, because polyester macromolecules in the ester base in the hydrolysis, but also can use appropriate alkali for polyester silk imitation treatment. (alkali reduction treatment)2., stretch and flexibility: polyester high strength, stretch growth, resilience, good, ordinary polyester strength of 35.2 ~ 52.8cN/tex, breaking elongation rate of 30% to 40%. According to the different processing, polyester has high strength, low extension, low strength, high extension and so on. Because of its high strength, great elasticity and good elasticity, polyester fiber has good wear resistance, which is second only to nylon. In addition, the high modulus polyester fabric, so crisp, good dimensional stability.3. moisture absorption and dyeing: Polyester structure close, high crystallinity, internal macromolecules without hydrophilic gene, so low moisture absorption, dyeing difficult. Polyester in general atmospheric conditions, moisture regain is only 0.4%. Therefore, the fabric has the advantages of easy washing and quick drying, and also reflects the defects of poor sweat absorption and poor ventilation.
Characteristics of polyester fiberStrength: the strength of polyester fiber is nearly 1 times higher than that of cotton, 3 times higher than that of wool, so the polyester fabric is durable.Heat resistance: can be used at 70~170 degrees, is the best in synthetic fiber heat resistance and thermal stability.Elasticity: Polyester Elastic close to wool, wrinkle resistance over other fibers, fabric wrinkle free, good shape.Abrasion resistance: polyester is second only to nylon in abrasion resistance, and occupies second place in synthetic fiber.Water absorption: Polyester moisture regain low, good insulation performance, but because of low water absorption, friction generated by static electricity, dyeing performance is poor.
100% polyester fabric permeability is very poor, but winter wear (non plateau) is still possible.
