摘要:
The purpose of this study is to investigate the correlation of fiber emissions during washing with the fabric properties such as fabric structure and finishing. Furthermore, we studied the biodegradability of fibers in marine environment compared to those in soil burial and the impact of fabric properties on the biodegradability. The results showed that the fabric which has the higher density of yarn and fabric and the more compact weave structure released less amount of fibers and the length of released fibers tend to be shorter. Peach skin finish with microfibers exposed on the surface released more and longer fibers whereas water-repellent finish reduced the fiber emission and fiber length. It was confirmed that an average of 16wt% of fiber was filtered through the washing machine, and the filtration rate increased as the length of the discharged fiber increased. The structural factors and physical properties of the fabric that influence the fiber release were identified, and the total amount of fiber emission decreased when the fabric has larger value of weave parameter, less fuzziness , stronger abrasion resistance and lower water absorbency. In addition, the fibers submerged in the 7℃ seawater showed a lower biodegradability compared with those submerged in 20℃ seawater or buried in soil. Also, water-repellent fabric was less biodegradable than the untreated one. Base on the results, different structure or finishing of fabrics could affect the amount of fiber emissions during washing and biodegradability in marine environment.
