What are the disadvantages of polypropylene?
Polypropylene is a thermoplastic polymer, which was developed in the mid -20th century. Over the years, polypropylene has been used in a number of applications, especially as a fiber for carpets and upholstery for furniture and car seats. Polypropylene was also beneficial with the plastic industry and provided cheap material that can be used to create a variety of plastic products for home and office. Although there is no doubt that polypropylene has a lot to do, there are disadvantages of using polymers of this nature.
One of the main disadvantages of polypropylene is that the product has resistance to the addition of color or ink after the cooling process is complete. This can make it difficult to work with raw materials, especially in applications where polypropylene is used to create domestic products such as shelf organizers. Manufacturers must be very careful to add the correct amount of color at the right time in a cold process or the material will be much more susceptible to cracking.
Regarding the use of polypropylene in carpet and upholstery, textile manufacturers must constantly realize the temperature of the machinery, while the fiber passes through the process. If the thread is too hot, there is a tendency to break and get stuck on the cylinders of many types of textile machines. Breaking, spinning, twisting and deformation machines must be carefully monitored to ensure that the refined fiber does not bite and begins to collect around the cylinder. When this happens, the material tends to melt and harden a substance that is very difficult.
The finished product must also be given special care. Polypropylene tends to reduce the wondered pattern or design. The permission of the average polymer shrinking speed causes the Žessible for the manufacturer to accurately assess the amount of polypropylene yarn or woven leaves of material for purchase. When it is done, it is much easier to calculate the correct amount of trimming that can be done and still produced a product withThe right dimensions.
