Embodiment 1

[0025] After extruding the high-temperature molten synthetic resin melt of 4% (weight percent) of activated carbon and 96% (weight percent) of polyester spinning raw materials from the screw extruder, it passes through the spinneret, and then passes through the air with different temperatures. Cooling is carried out to become nascent fibers, and the nascent fibers are stretched, oiled, dried and shaped, packaged and other processes to finally form the porous activated carbon polyester fiber.

[0026] Wherein the temperature of the low-temperature cooling blower is 22-24°C, the wind speed is 2 m / s, the spinning speed is 700-1800 m / min, the number of holes in the spinneret is 600 holes, and the stretching rate is 150-160 m / min , The stretching temperature is 60-75°C, and the heat setting conditions are: the temperature is 145°C, and the heat setting time is 10-20 minutes.

[0027] The temperature of the seven zones during the extrusion process is: zone one 280-290°C, zone two 29...

Embodiment 2

[0030] After extruding the high-temperature molten synthetic resin melt of 1% (weight percentage) of activated carbon and 99% (weight percentage) of polyester spinning raw materials from the screw extruder, it passes through the spinneret, and then passes through the air with different temperatures. Cooling is carried out to become nascent fibers, and the nascent fibers are stretched, oiled, dried and shaped, then cut, packed and other processes are performed to finally form the porous activated carbon polyester staple fibers.

[0031] Wherein the temperature of the low-temperature cooling blower is 22-24°C, the wind speed is 5 m / s, the spinning speed is 700-1800 m / min, the number of spinneret holes is 600 holes, and the stretching rate is 150-160 m / min , The stretching temperature is 60-75°C, the heat setting conditions are: the temperature is 145°C, and the heat setting time is 20-30 minutes.

[0032] The temperatures of the seven zones during the extrusion process are: zone...

Abstract

The invention discloses a kind of multi-aperture active carbon polyester fiber and the manufacturing method. The product is made up of 0.1%-4% active carbon and 96%-99.9% polyester, the manufacturing method is: 1. melts the active carbon and polyester material with high temperature, them extrudes them out of the screw extruder, gets the spinning fused mass; 2. the fused mass is formed into effluxion through silk-spray board; 3. when the effluxion gets off the boards, it is generated into primary fiber through low temperature and high speed cool wind; 4. the active carbon polyester fiber can be acquired through extension, oil, drying and packaging process to the primary fiber.

Description

technical field [0001] The invention relates to a polyester fiber, in particular to a porous activated carbon type polyester fiber with activated carbon components, functions and structures and a manufacturing method thereof. Background technique [0002] Polyester fibers are used in a wide range, and are widely used in almost all fields of civil and industry. During the manufacturing process of polyester fibers, many functional materials can be added to make fibers with special functions to meet different needs. Therefore, adding Activated carbon activated carbon polyester fiber makes the fiber have the properties of activated carbon, especially suitable for fabric filling materials, decorative fabrics, non-woven fabrics, carpets, wool-like fabrics and filter materials. The Chinese patent with the application number "95119030" discloses the "Preparation Method of Hollow Activated Carbon Fiber", which discloses a single-hole hollow activated carbon fiber spinning method, but...
