Embodiment 1

[0030] Such as figure 2 As shown, the polyester melt is sprayed from the spinneret hole of the spinneret (1), and after cooling into fibers, the oil tanker (7) used for oiling before stretching and setting is used for pre-oiling, and the oiling rate is controlled at 0.18%. , after the high-temperature high-stretching and high-temperature heat-setting processing of the first hot roller (2) and the second hot roller (3), oil the nozzle (6) to 0.7%, and then wind it at the winder (5) around the shape. One heat roll (2) and two heat roll (3) surfaces and the yarn guide used therefor carry out the surface coating retreatment of nano-scale nickel-cadmium chromium alloy with low friction coefficient, requiring friction coefficient 0.08, spinning speed 4500m / min, one The stretching temperature of the hot roll is 100°C, the setting temperature of the second hot roll is 180°C, the draw ratio is 3.3, the oil nozzle is installed 12cm before the network nozzle (4), and the boiling water ...

Embodiment 2

[0032] Such as image 3 As shown, the polyester melt is sprayed from the spinneret hole of the spinneret (1), and after cooling into fibers, the oil tanker (7) used for oiling before stretching and setting is used for pre-oiling, and the oiling rate is controlled at 0.06%. , after the high-temperature, high-stretching and high-temperature heat-setting processing of the first hot roller (2) and the second hot roller (3), oil the oil to 0.8% at the oil nozzle (6), and then at the winding machine (5) Roll forming. One heat roll (2) and two heat rolls (3) surfaces and the yarn guide used therefor carry out the surface coating retreatment of nano-scale nickel-cadmium chromium alloy with low friction coefficient, spinning speed 4400m / min, one heat roll stretching temperature 150°C, the setting temperature of the second hot roller is 200°C, the draw ratio is 3.5, the nozzle is installed at 20cm behind the network nozzle (4), and the 150D / 96F low-shrinkage polyester polyester with a ...

Embodiment 3

[0034] Such as Figure 4As shown, the polyester melt is sprayed from the spinneret hole of the spinneret (1), and after being cooled into fibers, it is processed by a hot roller (2) and a second hot roller (3) at high temperature and high stretching and high temperature heat setting. Finally, use the oil nozzle to oil at the oil nozzle (6), and then wind and shape it at the winder (5) place. The oiling rate is controlled at 1.0%, the surface of a hot roll and the yarn guide used are not re-treated with a surface coating of nano-scale nickel-cadmium-chromium alloy with a low friction coefficient, the spinning speed is 4200m / min, and the stretching temperature of a hot roll is 150 ℃, the setting temperature of the second hot roller is 230 ℃, the draw ratio is 3.8, the oiling rate is controlled at 0.9%, the oil nozzle is installed at 18cm before the network nozzle (4), and the boiling water shrinkage rate is 2.5%, and the dry heat shrinkage rate is 8.5%. 800D / 192F low shrinkage ...

Abstract

The invention relates to polyester fully drawn yarn FDY and a production method thereof, and in particular to low-shrink polyester fully drawn yarn FDY and production method thereof. The technical problem to be solved is as follows: oiling through a posterior drawing and sizing oil nozzle or pre-oiling through an oil wheel, and oiling through the posterior drawing and sizing oil nozzle to the necessary value to realize high-temperature high-drawing and high-temperature thermal-sizing so as to produce shrink polyester FDY; the size of the textile is stable, so that the textile can be used on blanket home textile and in the industrial field; meanwhile, the invention is used for solving the problems of severe fuming of oil, production environment affect and industrialization difficulty caused by high-temperature production. The important steps of the method comprise: coating nanometer nickel-cadmium-chromium alloy on the surfaces of a first hot holler and a second hot roller and yarn guiders used by the same to reduce the friction coefficient to be smaller than 0.1, directly oiling through the posterior drawing and sizing oil nozzle or pre-oiling through the oil wheel, and oiling to the necessary value through the oil nozzle after the drawing and sizing procedures.

Description

technical field [0001] The invention relates to a fully drawn polyester yarn FDY for carpet or industrial use and a production method thereof, in particular to a fully drawn polyester yarn FDY for industrial low shrinkage polyester polyester for blankets and a production method thereof. Background technique [0002] Polyester is a kind of chemical fiber clothing fabric raw material that is widely used in daily life. The biggest advantage of its fabric is that it has good wrinkle resistance, easy washing and drying, and is suitable for outerwear. However, when polyester is used for home textiles such as carpets and blankets and for industrial use, its dimensional stability will have a large shrinkage and deformation after washing due to its high shrinkage in boiling water, making it difficult to continue to use. However, with the development of society and economy, home textiles There is an increasing demand for polyester polyester fiber for articles of daily use and industr...
