Embodiment 1
[0047] Production of filament bundles: First, the selected FDY filaments are bundled and paralleled to obtain untwisted multifilament bundles, and then the untwisted multifilament bundles are passed through the twisting process to increase the twist of 5T / 10cm, so as to obtain high rigidity twist Tow, and then high rigidity twisted tow through the winding process to obtain filament bundle; the breaking strength of the FDY filament is 5.2 cN / dtex.
[0048] Production of air-textured tow: Firstly, the selected POY filaments are bundled and combined to obtain untwisted multifilament bundles, and then the untwisted multifilament bundles are stretched, deformed, thermally stabilized, shaped, and wound in sequence process, to obtain the initial air-textured tow, and then the initial air-textured tow is passed through the winding process to obtain the air-textured tow; the elongation at break of the POY filament is 30%, and the POY filament undergoes deformation processing The overfe...
Embodiment 2
[0051] Production of filament bundles: First, the selected FDY filaments are bundled and doubled to obtain untwisted multifilament bundles, and then the untwisted multifilament bundles are passed through the twisting process to increase the twist of 30T / 10cm, so as to obtain high rigidity twist Tow, and then high rigidity twisted tow through the winding process to obtain filament bundle; the breaking strength of the FDY filament is 12.0 cN / dtex.
[0052] Production of air-textured tow: Firstly, the selected POY filaments are bundled and combined to obtain untwisted multifilament bundles, and then the untwisted multifilament bundles are stretched, deformed, thermally stabilized, shaped, and wound in sequence process, to obtain the initial air-textured tow, and then the initial air-textured tow is passed through the winding process to obtain the air-textured tow; the elongation at break of the POY filament is 60%, and the POY filament undergoes deformation processing The overfee...
Embodiment 3
[0055] Basic content is the same as embodiment 1, the difference is:
[0056] In the production of filament bundles: the untwisted multifilament bundles are passed through the twisting process to increase the twist of 20T / 10cm; the breaking strength of the FDY filaments is 8 cN / dtex.
[0057] In making air-textured tow: the elongation at break of the POY filament is 45%.
[0058] In the production of full-multifilament double-ply sewing thread: the diameter of the filament bundle is 75% of the diameter of the air-textured tow, and the Poisson's ratio of the full-multifilament double-ply sewing thread is -0.24.
