I. Differences in Raw Material Sources

Conventional polyester is a chemical fiber. It is a fiber-forming polymer prepared by esterification, transesterification, and polycondensation reactions of polyethylene terephthalate (PET), then processed into fibers through spinning and post-treatment. Ocean recycled polyester, by contrast, is a new type of polyester fiber regenerated from recycled marine waste (such as waste fishing nets and ships) via special treatment. Therefore, there is a significant difference in the raw material sources of the two.

II. Differences in Environmental Friendliness

Since ocean recycled polyester is regenerated from marine waste, it boasts high environmental friendliness. The promotion and application of this material help reduce marine garbage and protect the marine ecological environment. In comparison, the production process of conventional polyester may have certain impacts on the environment. Thus, ocean recycled polyester has obvious advantages in terms of environmental friendliness.

III. Differences in Performance

Although ocean recycled polyester and conventional polyester are nearly identical in physical properties, the former exhibits superior performance in some aspects. For example, due to the special recycling process adopted in ocean recycled polyester, its fiber structure may be denser, thereby enhancing the fiber’s strength and wear resistance. Additionally, ocean recycled polyester has good moisture absorption and air permeability, making textiles more comfortable and durable.

IV. Differences in Application Fields

Conventional polyester is widely used in clothing, household goods, industrial products and other fields. Ocean recycled polyester, with its unique environmental friendliness and excellent performance, is gradually gaining a foothold in the textile market. Especially as environmental awareness grows, more and more consumers tend to choose products made of eco-friendly materials, giving ocean recycled polyester broad market prospects.
