Embodiment 1
[0031] A preparation method of polyester crepe chine woven fabric,
[0032] (1) The preparation process of disperse dye normal pressure dyeable polyester fiber is as follows:
[0033] The normal pressure dyeable polyester melt (intrinsic viscosity is 0.65dL / g) is extruded from the three-lobed spinneret hole on the spinneret and cooled by ring blowing; wherein, in the preparation process of the normal pressure dyeable polyester, the The mol ratio of phthalic acid, isophthalic acid and diethylene glycol is 100:3:5, and the addition of polyethylene glycol is 9wt% of the addition of terephthalic acid;
[0034] The ratio of the included angle of the center line of the three lobes of the same three-lobed spinneret hole is 1.0:1.4:1.6, the length and width of the three lobes are the same and the ratio of length to width is 3:1; different three-lobed spinneret holes The shape and size of the three lobes are the same; all the three-lobed spinneret holes are distributed in concentric c...
Embodiment 2
[0043] A preparation method of polyester crepe chine woven fabric,
[0044] (1) The preparation process of disperse dye normal pressure dyeable polyester fiber is as follows:
[0045] The normal pressure dyeable polyester melt (intrinsic viscosity is 0.66dL / g) is extruded from the three-lobed spinneret hole on the spinneret and cooled by ring blowing; wherein, during the preparation of the normal pressure dyeable polyester, the The mol ratio of phthalic acid, isophthalic acid and diethylene glycol is 100:5:6, and the addition of polyethylene glycol is 9wt% of the addition of terephthalic acid;
[0046] The ratio of the included angle of the center line of the three lobes of the same three-lobed spinneret hole is 1.0:1.5:1.7, the length and width of the three lobes are the same and the ratio of length to width is 3:1; different three-lobed spinneret holes The shape and size of the three lobes are the same; all the three-lobed spinneret holes are distributed in concentric circl...
Embodiment 3
[0055] A preparation method of polyester crepe chine woven fabric,
[0056] (1) The preparation process of disperse dye normal pressure dyeable polyester fiber is as follows:
[0057] The normal pressure dyeable polyester melt (intrinsic viscosity is 0.7dL / g) is extruded from the three-lobed spinneret hole on the spinneret and then cooled by ring blowing; wherein, during the preparation of normal pressure dyeable polyester, the The mol ratio of phthalic acid, isophthalic acid and diethylene glycol is 100:4:6, and the addition of polyethylene glycol is 10wt% of the addition of terephthalic acid;
[0058] The ratio of the included angle of the center line of the three lobes of the same three-lobed spinneret hole is 1.0:2.0:2.5, the length and width of the three lobes are the same and the ratio of length to width is 3.5:1; different three-lobed spinneret holes The shape and size of the three lobes are the same; all the three-lobed spinneret holes are distributed in concentric ci...
