Embodiment 1

[0040] Pre-treatment (including sorting, crushing and cleaning) and drying of waste recycled PET bottle flakes are carried out, and then the washed bottle flakes are put into the vacuum drum dryer. Steam or heat transfer oil, rotate the drum at the same time, keep the temperature at 140 ℃, start the vacuum pump at the same time, keep the vacuum at 0.08MPa, dry for 9 hours, the moisture content of the dried polyester bottle flakes is 90, and the far-infrared mother The granules and negative ion masterbatch are dried. The drying process is mainly to put them into a sealed silo, and the bottom of the silo is fed with dried hot air, the temperature is kept at 125 °C, and the drying time is 10.5 hours. And the moisture content of negative ion masterbatch is 55ppm.

[0041] Then, the dried waste recycled PET bottle flakes, far-infrared masterbatch and negative ion masterbatch are sent to the metering feeder for mixing. The dried far-infrared masterbatch and negative ion masterbatch...

Embodiment 2

[0046] Pre-treatment (including sorting, crushing and cleaning) and drying of waste recycled PET bottle flakes are carried out, and then the washed bottle flakes are put into the vacuum drum dryer. Steam or heat transfer oil, rotate the drum at the same time, keep the temperature at 150 ℃, start the vacuum pump at the same time, keep the vacuum degree at 0.09MPa, the drying time is 11 hours, the moisture content of the dried polyester bottle flakes is below 85ppm, and the remote The infrared masterbatch and the negative ion masterbatch are dried. The drying process is mainly to put the far infrared masterbatch and the negative ion masterbatch into the sealed silo. The bottom of the silo is fed with dry hot air, and the temperature is kept at 135 ° C and the drying time is 11 hour, the moisture content of the dried far-infrared masterbatch and negative ion masterbatch is 50ppm.

[0047] Then, the dried waste recycled PET bottle flakes, far-infrared masterbatch and negative ion ...

Abstract

The invention discloses a method for preparing anion far-infrared short fibers employing waste renewable polyester bottle flakes. The method comprises the following steps: pretreating and drying the recycled waste renewable polyester bottle flakes; carrying out drying treatment on far-infrared masterbatch and anion masterbatch; feeding the dried polyester bottle flakes, the far-infrared masterbatch and the anion masterbatch to a special metering feeder for mixing, so as to obtain a mixture; carrying out melted extrusion on the mixed mixture by a screw to obtain a melt; filtering the melt, metering and spinning, cooling by cross blowing, winding and oiling, feeding by traction, filling fibers and doffing; carrying out bundling treatment on the fibers inside a barrel, and carrying out the procedures such as drafting, oiling, fiber folding, curling, thermoforming, cutting off and the like by oil bath, so as to obtain the anion far-infrared short fibers. The method disclosed by the invention is reasonable in preparation technology, and strong in maneuverability. The product prepared by the method disclosed by the invention is lower in selling price than the product prepared from native polyester. Therefore, the method has good economic benefits and social benefits.

Description

technical field [0001] The invention specifically relates to a method for preparing far-infrared anion short fibers from discarded regenerated polyester bottle flakes, and belongs to the field of resource regeneration and the field of chemical fiber technology manufacturing. Background technique [0002] With the improvement of people's living standards, the application fields of textiles are becoming more and more extensive, and the society's requirements for textiles are also getting higher and higher. Therefore, endowing textiles with far-infrared and negative ion functions has a positive effect on improving people's quality of life and increasing the added value of textiles. Significance. [0003] The far-infrared anion short fibers currently available on the market are mainly made by finishing ordinary polyester fibers with surface processing technology, or adding far-infrared anion masterbatches to raw polyester chips to make fibers. Although the former can temporarily...
