Example Embodiment
[0098] Specifically, such as Figure 1 to Figure 3 As shown, the preparation method of a hydrophilic moisture-conducting secondary stranded porous fiber 300D / 546 is produced by the above-mentioned production equipment, which specifically includes the following steps:
[0099] Polyester device → filter → booster pump → heat exchanger → interchange static mixer → metering pump melt extrusion → spinning assembly spinneret melt extrusion 20 tows → ring blowing cooling forming → double nozzles Oil→Single-rod double-headed double-headed guide wire guide wire hook frame guide→Spinning tunnel→Comb-shaped divider once twisted into 10 tows→Pre-network device→First guide wire plate→Secondary at main network device The stranding is 5 tows→the second godet→winding forming.
[0100] Among them, in the polyester reaction, from the level of polyester molecular structure design, the introduction of polyhydroxy monomers and polyethylene glycol macromolecules into the polyester molecular chain to co...
