Embodiment 1
[0040] The cross-section of the polyester pre-oriented yarn in this embodiment is orange-shaped, which is composed of fibers with a "rice"-shaped cross-section and fibers with a petal-shaped cross-section; the fibers with a "rice"-shaped cross-section include the following mass ratio components : semi-dull polyester: antibacterial masterbatch = 1:0.02; the fiber with petal-shaped cross-section is composed of water-soluble polyester; wherein, the quality of water-soluble polyester accounts for 25% of the sum of the mass of water-soluble polyester and semi-dull polyester . The antibacterial masterbatch is prepared by blending nano-silver antibacterial agent and polyethylene terephthalate at a mass ratio of 1:1. The nano-silver antibacterial agent is nano-silver supported by nano-carrier zirconium phosphate, and the particle size is 100-200nm.
[0041] The preparation method of the polyester pre-oriented yarn in this embodiment includes: mixing the antibacterial masterbatch and ...
Embodiment 2
[0050] The cross-section of the polyester pre-oriented yarn in this embodiment is orange-shaped, which is composed of fibers with a "rice"-shaped cross-section and fibers with a petal-shaped cross-section; the fibers with a "rice"-shaped cross-section include the following mass ratio components : semi-dull polyester: nano-silver antibacterial agent=1:0.1; the fiber of petal-shaped section is made up of water-soluble polyester; wherein, the quality of water-soluble polyester accounts for 75% of the sum of water-soluble polyester and semi-dull polyester quality %. The antibacterial masterbatch is prepared by blending nano-silver antibacterial agent and polyethylene terephthalate at a mass ratio of 1:0.5. The nano-silver antibacterial agent is nano-silver supported by nano-carrier silicon dioxide, and the particle size is 100-200nm.

Embodiment 3
[0059] The cross-section of the polyester pre-oriented yarn in this embodiment is orange-shaped, which is composed of fibers with a "rice"-shaped cross-section and fibers with a petal-shaped cross-section; the fibers with a "rice"-shaped cross-section include the following mass ratio components : semi-dull polyester: antibacterial masterbatch = 1:0.05; the fiber with petal-shaped cross-section is composed of water-soluble polyester; wherein, the quality of water-soluble polyester accounts for 40% of the sum of the mass of water-soluble polyester and semi-dull polyester . The antibacterial masterbatch is prepared by blending nano-silver antibacterial agent and polyethylene terephthalate at a mass ratio of 1:0.2. The nano-silver antibacterial agent is nano-silver supported by nano-carrier zirconium phosphate, and the particle size is 100-200nm.
[0060] The preparation method of the polyester pre-oriented yarn in this embodiment includes: mixing the antibacterial masterbatch an...
