Embodiment

[0010] Embodiment, this example is the technological process of ultra-fine denier polyester filament:

[0011] Polymerization melt→melt conveying→spinning box→metering pump→component→inner ring blowing cooling→cluster oiling→column→pre-network→first godet→main network→second godet→winding→ Inspection→Balance→Transfer false twist

[0012] POY→raw frame→cutter→first roller→twist stopper→first hot box→cooling plate→false twister→second roller→networker→auxiliary roller→second hot box→third roller→explorer Filament→oiling roller→winding→inspection→packing

[0013] The processing method is completed by two processes of spinning and texturing. The spinning adopts the inner ring air blowing cooling technology, and the texturing adopts the combination technology of 1-3-1 polyurethane friction sheet.

[0014] The following table shows the physical properties of POY:

Abstract

The invention relates to a process technology of 48 decitex 144 hole super-fine polyester filament by direct melt direct circular blow technology and POY-DIY line, from the following areas: (1) the overall denier is small, so that 0.6-0.9 metering pump can keep stable reliable speed; (2) the synchronization role of the pressure and the temperature is attained by properly increasing bath temperature, properly reducing viscosity and properly increasing spin pack pressure in the component assembly; (3) the plate is repaired by silicon oil before exflagellation, the injection phenomenon is solved. The tow after leaving the hole is hard to reach the spinning cabinet, through adjusting the pressure of the first floor and second floor, so that second floor is positive pressure and first floor is negative pressure as far as possible. The spinning is sealed independently completely, and no interference by amorphism air current. The pressure and absorbing rate of suction-gun are decreased to absorb mildly the head which have no spinning damage. By 1-3-1 PU disc combination to texturing DTY, this production process can reduce the production cost, stable product quality and green environment protection.

Description

technical field [0001] The invention relates to a synthetic fiber technology, in particular to a production and processing technology of polyester low elastic yarn. Background technique [0002] As one of the three main fibers in synthetic fibers, polyester is widely used in clothing fabrics and other non-clothing fields because of its excellent physical and chemical properties. Since its inception, polyester products have also been used by downstream users as the main textile raw material for weaving various textiles due to their good drape, high strength, crispness, and resistance to tending. However, most polyester filament varieties are concentrated between 50 denier and 300 denier. In recent years, polyester filament products such as ultra-fine denier and micro-denier have been developed and produced one after another. Few people do the development and production of it. [0003] Polyester superfine denier filaments are widely used in artificial suede synthetic leather...
