Problems solved by technology

[0003] However, with the improvement of people's living standards, ordinary polyester fabrics cannot meet the needs in terms of skin-friendliness, soft feel and bright color.
At present, the cross-section of many fibers on the market is circular, pentagonal, rectangular or straight, and the cross-section of the fiber has a small reflection area for light, so the gloss of these fibers is not very bright, and the fiber fabric Both skin-friendly and soft feel need to be further improved

Embodiment 1

[0015] Below in conjunction with accompanying drawing, the utility model is further described.

[0016] Such as figure 1 As shown, the preparation and processing method of a kind of double-faced fleece fleece fiber described in this embodiment, the steps are as follows:

[0017] The first step, the selection of raw materials: purified terephthalic acid and PET polyester melt obtained by chemical reaction of PTA, ethylene glycol and catalyst, and the viscosity of PET polyester melt is 0.629dl / g;

[0018] The second step, production preparation: through booster pump→melt distribution valve→spinning box→metering pump melt extrusion→staggered spinning assembly→cooling forming→single nozzle oiling→spinning channel→pre-network →GR1 godet→GR2 godet→automatic winding→mechanical doffing→quality inspection, to prepare a double-sided fleece fiber with a monofilament linear density of 0.97dtex; in which the PET polyester melt is passed through a The pressure pump delivers the flow rate ...

Embodiment 2

[0023] The preparation and processing method of a kind of double-faced fleece fleece fiber described in this embodiment, the steps are as follows:

[0024] The first step, the selection of raw materials: purified terephthalic acid and PET polyester melt obtained by chemical reaction of PTA, ethylene glycol and catalyst, and the viscosity of PET polyester melt is 0.641dl / g;

[0025] The second step, production preparation: through booster pump→melt distribution valve→spinning box→metering pump melt extrusion→staggered spinning assembly→cooling forming→single nozzle oiling→spinning channel→pre-network →GR1 godet→GR2 godet→automatic winding→mechanical doffing→quality inspection, to prepare a double-sided fleece fiber with a monofilament linear density of 0.97dtex; in which the PET polyester melt is passed through a The pressure pump delivers the flow rate of 156T to the melt distributing valve; the spinneret hole on the spinneret plate is oval and flat, and the diameter of the sp...

Abstract

The invention relates to the field of technologies for producing polyester filament yarns, in particular to a method for preparing and processing differential double-sided wool escaping pile fibers. By the aid of the method, the sectional spinning areas of the fibers can be increased, the fibers have bright colors, and pile soft hand feel of the fibers can be guaranteed. The method for preparing and processing the double-sided wool escaping pile fibers includes firstly, selecting raw materials including purified terephthalic acid and PET (polyethylene terephthalate) polyester melt, and the like. Chemical reaction is carried out on PTA (purified terephthalic acid), ethylene glycol and catalysts to obtain the PET polyester melt, and the viscosity of the PET polyester melt is 0.618-0.645 dl / g. The method for preparing and processing the double-sided wool escaping pile fibers has the advantages that the shapes of spinneret holes in the original spinneret plates are changed, the sectional areas of the fibers are adjusted by the elliptical flat spinneret holes, the light reflection areas of the sectional sides of the fibers can be increased, and accordingly colors and pressing marks of fabrics can be improved; the quantity of the spinneret holes in the surfaces of the spinneret plates in the unit area is increased, accordingly, the linear density of the fibers can be reduced, and the skin friendliness and soft pile hand feel of the fiber fabrics can be improved.

Description

technical field [0001] The invention relates to the technical field of polyester filament production, in particular to a method for preparing and processing differentiated double-sided wooly fibers. Background technique [0002] Polyester is one of the most widely cited chemical fibers. With the continuous development of polyester differentiated functional fibers in recent years, polyester has developed into an indispensable raw material for clothing, luggage, decoration and other textile industries in people's daily life. [0003] However, with the improvement of people's living standards, ordinary polyester fabrics cannot meet the needs in terms of skin-friendliness, soft feel, and bright color. At present, the cross-section of many fibers on the market is circular, pentagonal, rectangular or straight, and the cross-section of the fiber has a small reflection area for light, so the gloss of these fibers is not very bright, and the fiber fabric Both the skin-friendly and s...
