• Includes the following bio-based chemical fiber manufacturing activities：
• New cellulose fibers: Lyocell fiber, ionic liquid cellulose fiber, cellulose carbamate fiber, low temperature alkali/urea solution cellulose fiber, bamboo pulp fiber, hemp pulp fiber;
• Bio-based synthetic fibers (polyhydroxybutyrate hydroxyvalanoate (PHBV) and polylactic acid (PLA) blended fiber, polyethylene terephthalate 1,3-propylene glycol (PTT) fiber, polyethylene terephthalate 1,4-butanediol (PBT) fiber, polyethylene terephthalateMixed glycol ester (PDT) fiber, polybutylene succinate (PBS) fiber, polyamide (PA56) fiber, bio-based polyester fiber (PTT fiber, PBT fiber, PDT fiber, PBS fiber, etc.), bio-based polyamide fiber (PA612 fiber, etc.));
• Biological protein fiber: soy protein fiber, milk protein fiber, silkworm pupa protein fiber, animal hair protein fiber;
• The following product manufacturing activities are included in this category;
• Marine bio-based fiber (chitosan fiber, alginate fiber);
• Bio-based regenerated fiber;
• Recycled fiber;
• Fiber reinforced polymer composite material;
• Bio-based medical materials (collagen, chitosan, etc.);
• Biomass fiber;
