1. Production of Polypropylene Polypropylene fibers produced by solution polymerization method. The thermal decomposition temperature of 350 ~ 380C, melting point of 150 ~ 176C, so the use of soft spinning method.
2. Characteristics and Uses of Polypropylene Relative Density: Polypropylene is the smallest of all synthetic fibers in terms of total relative density, so it is the lightest, and the weight per unit of fiber can cover the largest area.
Strength: The strength of polypropylene is similar to that of high-strength polyester and nylon in synthetic fiber, but its strength does not change in the wet state. This is better than nylon.
Abrasion Resistance: The flat wear resistance of polypropylene is second only to nylon, but the resistance to abrasion is slightly inferior. Corrosion resistance: It has remarkable stability to inorganic acid and alkali.
Hygroscopicity: Polypropylene's moisture absorption is minimal, fabric shrinkage is small.
Disadvantages: poor lightfastness, poor dyeability, high electrostatic, poor flame resistance.
In addition, polypropylene, like other synthetic fibers, is not susceptible to mildew, rot, and insects. Polypropylene is mainly used for carpets (including carpet backings and suede), decorative fabrics, geotextiles, non-woven fabrics, various ropes, strips, fishing nets, building reinforcements, and packaging materials. Among them, polypropylene nonwovens have drawn attention due to their large number of applications in baby diapers and sanitary napkins.
