Problems solved by technology

[0004] However, when the side blowing device cools the large-diameter POY, because the side blowing device only continuously blows air on one side of the POY filament, the POY filament may be deformed by the airflow blown out by the side blowing device, making the POY filament After cooling and forming, the shape of its cross section changes, which affects the quality of POY wire

Embodiment 1

[0039] Embodiment one: if figure 1 with figure 2 As shown, a POY filament cooling device and its cooling process include a mounting frame 1 arranged on the discharge side of a screw extrusion spinning machine, and a plurality of heat conduction cooling blocks 2 are arranged on the mounting frame 1 . Such as Figure 4 As shown, an insertion slot 28 is provided on the side wall of the heat conduction cooling block 2, and a heat conduction cooling jacket 5 is inserted in the insertion slot 28, and a tow channel 21 for a single tow to pass through is provided on the heat conduction cooling jacket 5 . The tow channel not only has a certain shaping effect on the tow, so that the tow is not easy to be deformed, but also makes the tow not easy to be bonded to each other.

[0040] Both the heat conduction cooling block 2 and the heat conduction cooling jacket 5 are made of inorganic non-metallic materials, such as beryllium oxide ceramics. The thermal conductivity of beryllium oxid...

Embodiment 2

[0059] Embodiment 2: A cooling process of a POY wire cooling device, including primary cooling, using a heat-conducting cooling jacket 5 made of inorganic non-metallic materials to conduct heat conduction on the tow, and then using 3 cooling hoses containing flowing fluid to conduct heat conduction. Contact cooling is carried out by the heat conduction cooling jacket 5;

[0060] For secondary cooling, use the heat conduction cooling block 2 made of inorganic non-metallic materials to conduct heat conduction on the heat conduction cooling jacket 5 in the primary cooling, and then use the cooling hose 3 containing flowing fluid to conduct contact cooling on the heat conduction cooling block 2;

[0061] For third cooling, use another compacted cooling block 4 made of inorganic non-metallic material to conduct heat conduction to the heat conduction cooling block 2 in the secondary cooling, and then use the cooling hose 3 containing flowing fluid to compress the cooling block 4 Per...

Abstract

The invention relates to the technical field of spinning devices, in particular to a POY cooling device and a cooling technology thereof. The cooling device comprises an installation rack, a pluralityof yarn channels and a cooling medium, wherein the installation rack is provided with a plurality of heat-conducting cooling jackets which are made from an inorganic nonmetal material; the yarn channels are formed in the corresponding heat-conducting cooling jackets one to one, the heat-conducting cooling jackets are wound with cooling hoses, and the cooling medium is arranged in the cooling hoses. POY is extruded by a screw extrusion spinning machine and then penetrates through the yarn channels, heat on the POY is conducted into the cooling medium in the cooling hoses through the heat-conducting cooling jackets, and after the heat on the POY is lost, the POY is quickly cooled and shaped; when a single piece of POY penetrates through the corresponding yarn channel, the yarn channel has acertain shaping effect on the POY, and therefore, the POY is not prone to deformation. By means of the cooling device, the production quality of the POY is improved.

Description

technical field [0001] The invention relates to the technical field of spinning equipment, in particular to a POY filament cooling device and a cooling process thereof. Background technique [0002] Bamboo activated carbon powder and nano-scale tourmaline powder are usually added to the existing POY yarn during the preparation process to endow the POY yarn with moisture-absorbing and mildew-proof effects, and the outer layer of the POY yarn will be coated with water-based PU emulsion and nano-cooling mica powder The cooling antistatic layer composed of body and antistatic agent has the effects of cooling and toning the skin, lowering the body surface temperature and antistatic effect. [0003] In the production process of POY yarn, it is usually necessary to melt, measure and spin the raw material by the screw extrusion spinning machine before extrusion, and then use the side blowing device to cool and shape the POY yarn by side blowing, and finally The cooled and formed PO...
