Problems solved by technology

At present, there are still some gaps in the internal index of the product compared with similar foreign products in the current domestic general spinning technology. For example, the degree of irregularity is not enough, and the aspect ratio of the general fiber section is about 5, so the hand feeling and luster effect of the fabric are poor, and it is breathable. Sexuality and hygroscopicity are not good

Embodiment 1

[0022] Example 1 The in-line special-shaped FDY yarn with a diamond luster and a specification of 83dtex / 18f was produced.

[0023] This product adopts the one-step production route of melt direct spinning. The PET obtained by the polymerization of PTA and EG passes through the melt filter, then is boosted and transported by the gear pump, cooled by the cooler, and then distributed to each spinning position. Each spinning position is metered. The pump sends the melt quantitatively to each spinning assembly. After the melt is filtered by the filter layer in the spinning assembly and evenly pressurized, it passes through the capillary-shaped spinneret (the spinneret is in the spinning assembly, and the inline surface and The horizontal direction is at an angle of 45°) in the form of thin stream spraying. After the melt stream is cooled by side blowing at constant temperature and humidity, it is solidified into filaments, and then oiled by the tanker, drawn and shaped, added to th...

Embodiment 2

[0034] Example 2 Production of in-line special-shaped FDY yarns with a specification of 120dtex / 72f and diamond luster.

[0035]This product adopts the one-step method of melt direct spinning. The polyester melt (PET) is boosted and transported by the gear pump after passing through the melt filter, cooled by the cooler, and then distributed to each spinning position. Each spinning position is controlled by a metering pump. The melt is quantitatively sent to each spinning assembly. 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 assembly, and the straight surface and the horizontal The direction is at an angle of 45°) in the form of thin stream spraying. After the melt stream is cooled by side blowing at constant temperature and humidity, it solidifies into filaments. After oiling on the tanker, drawing and shaping, adding the main network, ...

Embodiment 3

[0045] Example 3 The in-line special-shaped FDY yarn with a specification of 76dtex / 18f and diamond luster was produced.

[0046] This product adopts the one-step production route of melt direct spinning. The PET obtained by PTA and EG polymerization passes through the melt filter, then is boosted and transported by the gear pump, cooled by the cooler, and then distributed to each spinning position. Each spinning position is controlled by The metering pump sends the melt quantitatively to each spinning assembly. After the melt is filtered by the filter layer in the spinning assembly and evenly pressurized, it passes through the capillary-shaped spinneret (the spinneret is in the spinning assembly, and the shape Angle of 45° with the horizontal direction) in the form of thin stream spraying, the melt fine stream is cooled by side blowing at constant temperature and humidity, and then solidified into filaments, which are oiled by tankers, drawn and shaped, added to the main netwo...

Abstract

The invention discloses a polyester FDY filament with diamond luster and a preparation process thereof. The preparation process comprises that: according to a direct spinning FDY process route, PET fused mass is extruded and spun from spinneret orifices of a spinneret plate, cooled by lateral blow and solidified into silk; and the silk is oiled by an oiler, drawn and set, added with a main network and then wound into an FDY spinning cake, wherein the spinneret plate adopts a spinneret plate with a length-width ratio and I-shaped pores for spinning, the blade width is between 0.1 and 0.15mm, and the length-width ratio is between 17 and 20. The productivity of a single machine adopting the process is approximately doubled compared with the productivity of the single machine of a Japanese winding device with 12-end spinning, the energy consumption is reduced by 42 percent, the investment cost is greatly reduced and the economic benefit is improved; and the obtained fabric has special effect of the diamond luster, soft handfeel, and good ventilation property and moisture absorption.

Description

technical field [0001] The invention relates to a production technology of a differentiated high-performance polyester filament, in particular to a polyester FDY filament with diamond luster and a preparation process thereof, belonging to the technical field of chemical fibers. Background technique [0002] With the improvement of living standards and quality of life, people's requirements for clothing are getting higher and higher. Cotton, hemp and ordinary synthetic fiber fabrics can no longer meet people's growing needs due to their own characteristics and inherent limitations. Demand, especially in the aspect of outerwear and toy plush, people have put forward higher requirements, such as the fabric should be soft to the touch, good drapability, elastic, dry and delicate, etc., and higher requirements are also put forward for the gloss of the fabric requirements. [0003] According to our market research and information search, there are not many varieties of special-sh...
