[0024] Matsumoto HM100 spinning oil 0.7 parts,

[0025] 0.3 parts of Galston 624 anti-wicking agent;

[0026] After testing, its breaking strength is 7.05CN / dtex, the breaking elongation is 24.2%, the intermediate elongation (4.0CN / dtex) is 13.1%, and the dry heat shrinkage (take a tow with a length of 1m and hang it on a 0.01CN / dtex For heavy objects, put them in an oven at 190°C for 15 minutes, take them out and measure the length, and calculate the shortening ratio) to 2.3%, and the anti-absorption height (take a tow with a length of 30cm and hang a weight of 0.05CN / dtex on it, put it in 80 ℃ bake in the oven for 10 minutes, take it out and immerse it in the ink, and measure the ink rise height after 2 hours) to 2mm. ...

Embodiment 2

[0028] Another kind of product specification is the formulation of the anti-wicking type low-shrinkage polyester industrial yarn of 933dtex / 192f, in parts by weight as follows:

[0029] 100 parts of Hailide HLD301 high-viscosity PET with an intrinsic viscosity of 1.05,

[0030] Matsumoto HM100 spinning oil 0.8 parts,

[0031] 0.6 parts of Galston 624 anti-wicking agent;

[0032] After testing, its breaking strength is 7.15CN / dtex, the breaking elongation is 24.2%, the intermediate elongation (4.0CN / dtex) is 14.1%, and the dry heat shrinkage (take a tow with a length of 1m and hang it on a 0.01CN / dtex For heavy objects, put them in an oven at 190°C for 15 minutes and take them out to measure the length, calculate the shortening ratio) to 2.1%, and the anti-suction height (take a 30cm long tow and hang a weight of 0.05CN / dtex on it, put it in 80 ℃ oven for 10 minutes, then take it out and immerse it in the ink, and measure the height of the ink rise after 2 hours) to 1mm.

Embodiment 3

[0034] A preparation method of anti-wicking low-shrinkage polyester industrial yarn: the fiber-grade PET raw material with an intrinsic viscosity of 0.67 is crystallized and preheated and then put into a solid-phase polymerization reactor and protected under high-purity nitrogen (purity ≥ 99.999%) Carry out continuous solid-state polymerization at 210°C, and control the reaction temperature at 210°C for 25 hours to make the molecular weight of PET reach 30,000-35,000, and obtain Hailide HLD301 high-viscosity PET with an intrinsic viscosity of 1.05. The obtained Hailide HLD301 high-viscosity PET is measured in parts by weight and sent to the pre-spinning silo, fully melted by screw heating, the melting temperature is controlled at 300°C, the screw extrusion pressure is set at 13Mpa, and then measured by the melt metering pump Then enter the spinning assembly (192 holes) and spray out. The pressure before the spinning assembly is 14Mpa; the sprayed melt is cooled into filament bu...

Abstract

The invention relates to an anti-wicking low-shrink polyester (PET) industrial yarn and a preparation method thereof. The anti-wicking low-shrink PET industrial yarn is prepared by the steps of: carrying out melt spinning on high-viscosity PET chips which are used as raw materials, adding a proper amount of spinning oil, then carrying out stretching setting, adding a proper amount of anti-wicking agent, and then winding, wherein for a formula, the anti-wicking low-shrink PET industrial yarn comprises the following components in parts by weight: 100 parts of Hailide HLD301 high-viscosity PET, 0.5-1 part of Matsumoto HM100 spinning oil, and 0.1-0.6 part of Goulston 624 anti-wicking agent. The preparation method comprises the steps of solid-phase polymerization, melting, metering, cooling and forming, oiling, stretching, application of anti-wicking agent and winding. The product of the anti-wicking low-shrink PET industrial yarn not only has the intrinsic characteristics, including high breaking strength and small dry heat shrinkage, of the low-shrink PET industrial yarn, but also has the property of good hydrophobicity, and can be applied to the fields of high-grade light box advertising fabrics and swimming pool fabrics.

Description

technical field [0001] The invention belongs to the technical field of polymer fiber production, and in particular relates to an anti-wicking type low-shrinkage polyester industrial yarn and a preparation method thereof. Background technique [0002] In recent years, with the continuous expansion of demand for high-end light box advertising fabrics and swimming pool fabrics, the application of anti-wicking products in the market has also increased rapidly, making the market prospect of anti-wicking low-shrinkage polyester industrial yarns more and more broad. Ordinary low-shrinkage polyester industrial yarns have mediocre hydrophobic effects and cannot be used in high-end fields. Therefore, it has become an urgent task for polyester industrial yarn manufacturers to develop low-shrinkage polyester industrial yarns that not only have the inherent high strength and small dry heat shrinkage characteristics of low-shrinkage polyester industrial yarns, but also have good hydrophob...
