Chemical properties of polypropylene monofilament The scientific name is polypropylene fiber, the nearby flame melts, flammable, slowly burns in the fire, emits black smoke, the upper part of the flame is yellow, the lower part is blue, exhales the smell of oil, after burning the ash is hard and light yellow brown particles, the hand is easy to break. Physical properties of polypropylene monofilament 1, the shape of the end face of polypropylene flat and smooth, cross-section is circular. 2, density polyester has the advantage of light texture. Its density is only 0.91g/cm3. Because it is a small density variety of common chemical fibers, the same weight of acrylic fibers can get a higher coverage area than other fibers. 3, strong elastic acrylic acid high strength, large tensile, high initial coefficient, good elasticity. So propylene has good wear resistance. In addition, the humidity of propylene is basically the same as that of dry steel, so it is an ideal material for making fishing nets and cables. 4, moisture absorption and dyeing characteristics light and good heat preservation. Although there is almost no hygroscopicity, the heart has a strong absorption capacity and obvious hygroscopicity and perspiration. The hygroscopicity of propylene is very small, almost no hygroscopicity, and the humidity rate under general atmospheric conditions is close to 0. However, there is a core suction effect, which can transfer water vapor through the capillary tubes of the fabric, but it has no absorption effect itself. The chromaticity of propylene is not good and the spectrum is incomplete, but it can be made up by the method of stock solution coloring. 5, acid-alkali polypropylene has good chemical resistance, in addition to concentrated nitric acid, strong caustic soda, propylene resistance to acid and alkali is good, so suitable for use as filter materials and packaging materials.
