Abstract: A polylactic acid fiber is provided. The polylactic acid fiber includes a first polylactic acid material and a second polylactic acid material. The first polylactic acid material is encapsulated by the second polylactic acid material. Based on a total volume of the polylactic acid fiber being 100%, a volume of the second polylactic acid material is at least 20%. The second polylactic acid material includes 15 wt % to 85 wt % of poly(D-lactic acid) and 15 wt % to 85 wt % of poly(L-lactic acid).

Abstract: A biodegradable additive, a biodegradable polyester fiber and a method for producing the same, and a biodegradable fabric are provided. The biodegradable additive includes a polyester resin material and a biodegradable resin material. The biodegradable resin material is at least one material selected from the group consisting of polybutylene succinate (PBS), polybutylene adipate terephthalate (PBAT), polycaprolactone (PCL), polylactic acid (PLA), and derivatives thereof. In the biodegradable additive, a content range of the polyester resin material is between 40 wt % and 80 wt %, and a content range of the biodegradable resin material is between 20 wt % and 60 wt %.

Abstract: A recycled polyester fiber is provided. The recycled polyester fiber is made of a raw material by melt spinning. The raw material includes 95.0 wt % to 99.99 wt % recycled polyester pellet formed from recycled bottle chip and 0.01 wt % to 5.0 wt % titanium dioxide slurry. Based on the total weight of the titanium dioxide slurry, the titanium dioxide slurry includes 20 wt % to 50 wt % bio-oil acting as carrier, 50 wt % to 80 wt % titanium dioxide powder, 0.1 wt % to 5 wt % dispersant, 0.01 wt % to 3 wt % antioxidant, and 0.001 wt % to 0.1 wt % dye.
