Problems solved by technology

At present, there are very few chemical fiber manufacturers producing triangular special-shaped fibers in China, and they basically use regular triangular micro-hole spinnerets. The final triangular special-shaped fibers have a low degree of special shape, and the fabric flashing effect is not very bright.

Embodiment 1

[0020] Example 1 The production specification is 44dtex / 36F glossy triangular special-shaped polyester FDY yarn

[0021] This product adopts the one-step production route of melt direct spinning. The polyester melt (PET) obtained by PTA+EG polymerization passes through the melt filter, then is boosted and transported by the gear booster pump, cooled by the cooler, and then distributed to each spinning machine. Each spinning position sends the melt quantitatively to each spinning assembly by a metering pump. After the melt is filtered and uniformly pressurized through the filter layer in the spinning assembly, it passes through the capillary-shaped spinneret (the spinneret is in the spinning In the module, isosceles triangular micropores with a vertex angle of 60-80°. The length of the bottom side of the micropore is 0.3mm) is sprayed out in a thin stream, and the melt stream is cooled by side blowing at constant temperature and humidity, and then solidified After forming silk ...

[0040] Example 2 The production specification is 47dtex / 24F glossy triangular special-shaped polyester FDY yarn

[0041]This product adopts the one-step production route of melt direct spinning. The polyester melt (PET) obtained by PTA+EG polymerization passes through the melt filter, then is boosted and transported by the gear booster pump, cooled by the cooler, and then distributed to each spinning machine. Each spinning position sends the melt quantitatively to each spinning assembly by a metering pump. After the melt is filtered and uniformly pressurized through the filter layer in the spinning assembly, it passes through the capillary-shaped spinneret (the spinneret is in the spinning In the component, isosceles triangular micropores with an included angle of 60-80°. The length of the bottom side of the micropore is 0.3mm) is sprayed out in a thin stream, and the melt stream is cooled by side blowing at constant temperature and humidity, and then solidified After forming ...

Abstract

The invention discloses a production method for fine denier bright triangular profiled fiber, which is characterized in that the method adopts a melt direct spinning one-step production line and uses an isosceles triangle micro-hole spinneret plate with an apex angle ranging from 60 degrees to 100 degrees. Side length of the base of a micro-hole ranges from0.25mm to 0.35mm. A melt dosing pump with melt flow ranging from 0.5ccm / rev to 1.0 ccm / rev is used to convey polyester melt to each spinning assembly quantitatively. The fineness of obtained filament is less than 1.3dtex, and the hole number of multifilament ranges from 15 F to 48F. Bright triangular profiled polyester fully drawn yarn (FDY) obtained through the method not only has properties of good abrasive resistance, soft and smooth hand feel, breathing and good drapability, but also has a special flash effect.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for producing fine-denier glossy triangular special-shaped fibers. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for clothing fabrics are also constantly increasing, such as fabric softness, air permeability, and flashing effects. Therefore, the market demand for special-shaped fibers in China continues to increase, especially the special flashing effect and The hand feeling is deeply loved by users. At present, there are very few chemical fiber manufacturers producing triangular special-shaped fibers in China. They basically use regular triangular micro-hole spinnerets. The degree of special shape of the finally obtained triangular special-shaped fibers is not very high, and the fabric flashing effect is not very bright. Contents of the invention [0003] The object of the present invent...
