Biodegradable Polyester Fiber : ECO-AN®PSF(with CiCLO®)
(1) The polyolefin and polyester raw materials are modified and spun into fibers, which have the ability to biodegrade under aerobic and anaerobic conditions.
(2) In addition to the degradability of ECO-AN ®, the subsequent processability is not affected by it, which is consistent with the general fiber use method. There is no need to change the process at all, and it can be used with confidence.
(3) The degradability of ECO-AN ® will not affect other fibers shared with it.

Under certain environmental conditions, the degradable additives in PET will generate free radicals to break the chain of the ester groups in PET. The ester groups in PET are oxidized and reduced to terephthalic acid, and then the macromolecular chain segments in PET are cracked, the molecular weight decreases, and small molecules (about 10-50 carbons) are produced at the same time. At this time, the microorganisms in the environment will decompose these small molecules according to their own preferences and produce some excretions. These excretions are the so-called CO2, H2O, CH4, O2, N2 and salts. Therefore, the method of evaluating the degradability is to convert the amount of these gases into moles, and then calculate the degradation percentage of the fiber.
The degradation performance of ECO-AN ® PET fiber is shown in the figure. After testing the standard ASTM D5210, the degradation rate can reach 88% (847 days); the test standard ASTM D5988, the degradation rate can reach 88% (742 days); the test standard ASTM D6691, the degradation rate can reach 92% (844 days); the test standard ASTM D5511, the degradation rate can reach 91% (1278 days). In addition to good degradation ability, the physical properties and appearance of the fiber are not much different from that of ordinary fibers.
