The price of polyester yarn is influenced by several factors, and one crucial factor is the grade of the yarn. The grading system categorizes polyester yarn into different levels of quality, with lower grades typically associated with lower prices. As the grade decreases, there may be variations in the yarn's characteristics, such as strength, uniformity, and color consistency. Lower-grade polyester yarn may exhibit slight imperfections or inconsistencies, which can impact its overall price.
These grades cater to a range of market needs, with higher grades fulfilling the requirements of premium applications, while lower grades offer cost-effective options for applications where specific performance or aesthetic demands are not as critical. Manufacturers and consumers alike can choose from a range of polyester yarn grades, finding the balance between quality and affordability that best suits their needs.
