Embodiment 1
[0020] The present invention will be further described below in conjunction with the accompanying drawings.
[0021] Such as figure 1 , figure 2 , image 3 As shown, a polyester semi-gloss fine denier hollow POY fiber described in this example is composed of a semi-gloss polyester melt, the cross-sectional shape of the fiber is a hollow "*"-shaped structure, and the aspect ratio of the fiber cross-section is 6:1; the monofilament fineness of the fiber is 0.5dtex.
[0022] A kind of production method of polyester semi-light fine denier hollow POY fiber designed by the present invention, the steps are as follows:
[0023] Step 1: Using semi-glossy polyester melt as raw material, first put the semi-glossy polyester melt with an initial temperature of 278°C through the melt delivery pipeline 1, pressurize it to 180bar through the booster pump 2, and then send it to the melt cooler 3. Use the melt cooler 3 to cool the semi-gloss polyester melt to 276°C, and then send the semi-...

[0036] The present invention will be further described below in conjunction with the accompanying drawings.
[0037] Such as figure 1 , figure 2 , image 3As shown, a polyester semi-gloss fine denier hollow POY fiber described in this example is composed of a semi-gloss polyester melt, the cross-sectional shape of the fiber is a hollow "*"-shaped structure, and the aspect ratio of the fiber cross-section is 8:1; the monofilament fineness of the fiber is 1dtex.
[0038] A kind of production method of polyester semi-light fine denier hollow POY fiber designed by the present invention, the steps are as follows:
[0039] Step 1: Using semi-glossy polyester melt as raw material, first pass the semi-glossy polyester melt with an initial temperature of 280°C through the melt delivery pipeline 1, pressurize it to 200bar through the booster pump 2, and then send it to the melt cooler 3. Use the melt cooler 3 to cool the semi-gloss polyester melt to 278°C, and then send the semi-gl...
