Spinning equipment for producing porous fine denier polyester POY

Abstract

The invention relates to spinning equipment used for producing porous fine POY yarn, comprising a spinning box, a no-wind area, a blowing device, a passage and a winding machine, all of which are arranged sequentially from top to bottom, wherein, the blowing device is a sealed circular blowing device; when at the working state, the cooled wind cools the yarn beams which enter the blowing device in the circular direction for shaping; the wind quantity of a closed ring is reduced by more than 60% compared with the quantity of the side wind; the energy consumption of the circular blowing air conditioner is saved by 70% and the cooling stability thereof is greatly improved; furthermore, the circular blowing air conditioner is not disturbed by the external environment; the spinning equipment is beneficial to improving the production speed, further improves the production efficiency and improves the quality of the fine yarn product.

Description

technical field [0001] The invention relates to spinning equipment, in particular to equipment for producing porous fine denier POY yarns. Background technique [0002] Existing POY spinning equipment is usually composed of main parts such as spinning box, side blower window, oiling parts, tunnel, network and winding machine. The process mainly includes the following steps: melt, metering, Spinning, side blowing cooling forming, oiling, winding. Among them, the side blowing cooling and forming is realized by the way of blowing the filaments sideways. The rear part of the side blowing window is a honeycomb rectifying plate and the front part is open, which will cause uneven cooling of the monofilaments far and near from the windshield. The side blowing of the denier yarn is difficult to penetrate evenly, and the physical properties of the porous fine denier yarn produced are uneven in strength and evenness, which cannot meet the needs of post-texturing users. Due to the hig...

Problems solved by technology

Among them, the side blowing cooling and forming is realized by the way of blowing the filaments sideways. The rear part of the side blowing window is a honeycomb rectifying plate and the front part is open, which will cause uneven cooling of the monofilaments far and near from the windshield. The side blowing of the denier yarn is difficult to penetrate evenly, and the physical properties, strength and evenness of the porous fine denier yarn produced are not uniform, which cannot meet the needs of post-texturing users.

Due to the high wind speed required by the side blowing process, the operating load of the side blowing air conditioner is relatively high, the energy consumption is high, and equipment failures occur frequently

From the current practice of various manufacturers, it is impossible to use side blowing to produce qualified single-board 150D / 288f POY products. Only 75D / 144f joint stock production is used to produce 150D / 288f POY products. Due to the double-stock production output, the production The cost has increased significantly, and there are still some problems in the post-processing and use of joint-stock products
