Production process of energy-saving and environmentally-friendly direct-spinning FDY fine-denier cationic polyester filament

Abstract

The invention discloses a production process of an energy-saving and environmentally-friendly direct-spinning FDY fine-denier cationic polyester filament. The process flow comprises the steps of polymerization three-cylinder flow->melt distributor->booster pump->melt transport->cooler->static mixer->melt distribution valve->spinning box->metering pump melt extrusion->spinning assembly->ring blowing drum->cooling forming->magnetic ring->oil nozzle oiling->spinning shaft->yarn guide->GR0 ->first heat roll->second heat roller->third heat roller->fourth heat roller->fifth heat roller->GR1->GR2->main network->GR3->yarn guide->broken wire detector ->winder->fully automatic doffer->sky rail transportation->dyeing and classification->quality inspection packaging->stereo warehouse automatic storage. The production process of the energy-saving and environmentally-friendly direct-spinning FDY fine-denier cationic polyester filament not only achieves energy saving and environmental protection, butalso guarantees spinning quality.

Description

Technical field: [0001] The invention relates to the field of polyester yarn production, in particular to an energy-saving and environment-friendly production process of direct spinning FDY fine denier cationic polyester filament. Background technique: [0002] The draft winding device of the prior art consumes a lot of energy when producing FDY cationic polyester filaments, while the latest Japanese TMT draft winding device (for its structure, see Chinese Patent Publication No. CN 104911725A) is used to produce direct spinning FDY For fine denier cationic polyester filaments, the static electricity caused by the friction between the produced cationic polyester filaments is large, not only prone to wool and broken ends during stretching, but also lead to antistatic properties during weaving on the subsequent knitting machine. Poor, and the spinning tension required by the traditional cationic polyester filament is large, thereby reducing the production process of broken ends...

[0002] The draft winding device of the prior art consumes a lot of energy when producing FDY cationic polyester filaments, while the latest Japanese TMT draft winding device (for its structure, see Chinese Patent Publication No. CN 104911725A) is used to produce direct spinning FDY For fine denier cationic polyester filaments, the static electricity caused by the friction between the produced cationic polyester filaments is large, not only prone to wool and broken ends during stretching, but also lead to antistatic properties during weaving on the subsequent knitting machine. Poor, and the spinning tension required by the traditional cationic polyester filament is large, thereby reducing the production process of broken ends. When producing on this equipment, it is easy to cause GR2 to wrap around the yarn, resulting in broken ends, and after the spinning tension is high , It is not conducive to the optimization of the winding process, and abnormalities are prone to occur when the silk cake is formed. In addition, the traditionally produced cationic polyester is prone to uneven dyeing, which is a common problem in the industry.
