Examples
Embodiment 1
[0038] Example 1: pure PHBV fiber, FDY filament
[0039] Get 1000 grams of PHBV (HV molar content 1%) sample, vacuum dry at 70°C, spin at 225°C, spin at a speed of 300m / min, melt-spin, and then double-draw to obtain FDY fibers, which are knitted into cloth. After cleaning the spinning oil, dry it, prepare samples, and test the antibacterial properties.
Embodiment 2
[0040] Embodiment 2: pure PHBV fiber, FDY filament
[0041] Get 1000 grams of PHBV samples (HV molar content 5%), vacuum-dry at 70°C, spin at 225°C, spin at a speed of 700m / min, melt-spin, and then draw 2.5 times to obtain FDY fibers, which are knitted into cloth. After cleaning the spinning oil, dry it, prepare samples, and test the antibacterial properties.
Embodiment 3
[0042] Embodiment 3: pure PHBV fiber, FDY filament
[0043] Get 1000 grams of PHBV samples (HV molar content 10%), vacuum dry at 70°C, spin at 215°C, spin at a speed of 1500m / min, melt spin, then draw 2.5 times to make FDY fibers, knitting cloth. After cleaning the spinning oil, dry it, prepare samples, and test the antibacterial properties.
