Polypropylene is the trade name of polypropylene fiber, which is a fiber obtained by polymerization and melt spinning of propylene as a raw material. Polypropylene officially began industrial production in 1957, and is a rising star in synthetic fiber. Because polypropylene has the advantages of simple production process, low cost, high strength and light relative density, polypropylene has developed rapidly. Polypropylene is currently the fourth largest variety of synthetic fibers.
Polypropylene production includes short fibers, filaments and split fibers. The polypropylene film fiber is obtained by first forming a film into a film, and then stretching the film to split it into a network of fibrils. Polypropylene is widely used in the manufacture of industrial fabrics, nonwoven fabrics, and the like. Such as carpets, industrial filter cloth, ropes, fishing nets, building reinforcements, oil absorbing blankets and decorative fabrics. In terms of civilian use, polypropylene can be purely spun or blended with wool, cotton or viscose to make a variety of clothing. In addition, polypropylene film fibers can be used as packaging materials.
The main physical and chemical properties of polypropylene
1. The longitudinal direction of the polypropylene is flat and smooth, and the cross section is circular.
2. The biggest advantage of density polypropylene is its light weight. Its density is only 0.91g/cm3, which is the lightest of the common chemical fibers. Therefore, the same weight of polypropylene can obtain higher coverage than other fibers.
3. The strong stretch polypropylene has high strength, large elongation, high initial modulus and excellent elasticity. Therefore, polypropylene has good wear resistance. In addition, the wet strength of polypropylene is basically equal to dry strength, so it is an ideal material for making fishing nets and cables.
4. Hygroscopic and dyeable polypropylenes have little hygroscopicity and are almost non-hygroscopic, and the moisture regain under atmospheric conditions is generally close to zero. However, it has a wicking action that transfers water vapor through the capillary in the fabric, but does not itself absorb any absorption. The dyeability of polypropylene is poor, and the chromatogram is not complete, but the method of coloring the original liquid can be used to make up for the deficiency.
5. Acid-resistant and alkali-resistant polypropylene has good chemical resistance. In addition to concentrated nitric acid and concentrated caustic soda, polypropylene has good resistance to acid and alkali, so it is suitable for use as filter materials and packaging materials.
6. The light resistance and other polypropylene fibers have poor light resistance, poor thermal stability, easy aging, and are not resistant to ironing. However, it is possible to improve the anti-aging property by adding an anti-aging agent at the time of spinning. In addition, polypropylene has good electrical insulation, but it is easy to generate static electricity during processing.
Microfiber Washing gloves is mainly using chenille fabric as a positive to wipe clean work, chenille biggest characteristic is tiny fiber can clean and package more dirt and dust, security is not paint, can absorb a large number of moisture at the same time, with a few washing liquid, foaming, make cleaning easier, based on these characteristics, microfiber chenille has become a car washing gloves The mainstream choice for beauty .
