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.

Abstract
The present invention discloses applications of PHBV as a novel natural antibacterial material in textile product preparation. According to the present invention, the mixture of pure PHBV or a PHBV copolymer and other polymers or copolymers is injected into extrusion equipment with a heating device, melting is performed, fibers are collected at a temperature of 170-225 DEG C under 300-3000 m/min, and FDY long fibers are prepared according to a drawing ratio of 2-4, or short fibers are prepared according to a conventional short fiber process; during the preparation of fabrics, the fabric can be prepared completely from the PHBV long yarn or the short-fiber yarn, and can further be prepared by carrying out mixed weaving or blending on the PHBV fibers and other fiber materials; PHBV as the completely bio-based novel natural environmentally-friendly antibacterial material has characteristics of high antibacterial rate, lasting antibacterial property, no toxicity, no harm, good biocompatibility and the like; and various fabrics having different PHBV fiber contents of the present invention have excellent antibacterial property, and can maintain the good antibacterial function after water washing 20 times.
Description
technical field [0001] The invention belongs to the technical field of polymer materials, and relates to the application of a novel biological polymer material: poly-3-hydroxybutyrate valerate PHBV as a novel natural antibacterial agent in the textile field. Background technique [0002] With the rapid increase of production capacity, China has become the main processing base of chemical fiber products in the world. However, due to the similarity of product varieties, various production enterprises have inevitably entered the vicious circle of low-price competition, making the profit margin of enterprises A sharp drop, or even a loss. In order to change this situation, various enterprises have intensified the development of new products, striving to create new market opportunities and increase new profit growth points for enterprises through differentiated and functional development. [0003] Because in daily life, people will be constantly exposed to various microorganisms...
