Embodiment approach

[0041] As an embodiment of the present invention, the inside of the impurity removal tank 1 is located below the short water inlet pipe 4 and is fixed with an inclined liquid separator 18; the cavity inside the liquid separator 18 is connected to one end of the pipe fitting Connected; the liquid separator 18 is uniformly provided with water outlet holes 17; the water outlet 17 is inclined towards the short water inlet pipe 4; during work, the water flowing out from the fiber filament sorting pool 2 enters the liquid separator 18 through the connecting pipe fittings In the inner cavity, and spray out from the water outlet hole 17 on the liquid separator 18, the sprayed water can stir the polyester fiber filaments located on the liquid surface of the impurity removal tank 1, and accelerate the polyester fiber filaments. The shedding of metal impurities on the surface can improve the removal efficiency while improving the quality of the removal of impurities; and because the water...

Abstract

The invention belongs to the technical field of fiber production, and particularly discloses a production technology of polyester staple fibers. A polyester fiber piece is processed by the productiontechnology according to the following steps that S1, the polyester fiber piece is put into a rotary drum to be subjected to high-temperature drying treatment; S2, the polyester fiber piece in the S1 is cut to be fibrous; S3, cut fibrous polyester fibers are sterilized by steam and can become fluffy; S4, the steamed polyester fibers is put into an impurity removal pool of a processing device and soaked for 1-2 hours; S5, after a sealing plate is pulled open, a water pump and a conveying belt are started, and the polyester fibers which are subjected to impurity removal are collected on the conveying belt; and S6, the polyester fibers which enable metal impurities to be removed are heated to be molten, then the follow-up fiber spraying operation, traction and fiber stacking operation are conducted, then the polyester fibers which are subjected to fiber stacking operation are cut, and therefore the polyester staple fibers can be obtained. According to the production technology, the polyester fibers are steamed to be fluffy, then the impurity removal pool is arranged, the metal impurities on the surfaces of the fluffy polyester fibers can be rinsed inside the impurity removal pool, andtherefore the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of fiber production, in particular to a polyester staple fiber production process. Background technique [0002] Polyester staple fiber is a fiber obtained after polyester (polyethylene terephthalate, PET) is polymerized by PTA and MEG and then spun into tow. PET is in the shape of rice grains and has various varieties. 75% is used for polyester for chemical fiber. According to the requirements of the textile industry, polyester staple fiber and polyester filament are manufactured; strength: the strength of polyester fiber is nearly 1 times higher than that of cotton and 3 times higher than that of wool, so polyester fabric is strong and durable; heat resistance : It can be used at 70°C to 1700°C. It is the best heat resistance and thermal stability among synthetic fibers; Elasticity: The elasticity of polyester is close to that of wool, and its wrinkle resistance exceeds other fibers. The fabric does not w...
