Problems solved by technology

Although this kind of fiber achieves a cool effect, it uses minerals as additives, which has defects such as high production and processing costs, difficult molding, and limited heat capacity. At the same time, minerals may occur due to compatibility problems between fiber materials and minerals Precipitation affects wearing comfort

Embodiment 1

[0023] This embodiment describes a preparation method of ultrafine denier absorbent and cooling antibacterial fiber,

[0024] (1) Preparation of polyester melt

[0025] PTA and EG enter the slurry preparation tank through the PTA transmission pipeline and the EG transmission pipeline respectively, and the slurry is mixed uniformly under the action of the stirring motor, and the slurry is transported to the slurry feeding tank, and then the slurry is input into the esterification reaction In the kettle, after the esterification is completed, it passes through a metering injection pump, a catalyst feeding device, a pre-polycondensation reactor, a final polymerization reactor and other equipment to obtain a PET polyester melt. Esterification temperature is 270℃, steam pressure is 2.1kg / cm 2 , The pre-polycondensation temperature is 285°C, the final polycondensation temperature is 290°C, and the obtained polyester melt viscosity is 0.620dl / g.

[0026] (2) Preparation of micro-mixed poly...

Embodiment 2

[0035] This embodiment describes a method for preparing ultrafine denier absorbent and discharging icy antibacterial fibers. The "preparation of nano-icy jade powder micro-mixed polyester melt" adopted in this embodiment is inconsistent with embodiment 1, and the others are the same as in embodiment 1.

[0036] Preparation of micro-mixed polyester melt of nano-icy jade powder

[0037] After the nano-icy jade powder is dried and extruded and melted, it is measured by a metering pump with a mass content ratio of 0.8%, and then enters the spherical cavity-shaped high-efficiency dynamic mixer; the polyester melt prepared in step (1) is transported through the melt After the pipeline is pressurized by the booster pump, the melt cooler, and the distribution valve are divided into the spinning box, and then enters the spherical cavity-shaped high-efficiency dynamic mixer to fully mix with the nano-icy jade powder to obtain a small amount of nano-icy jade powder Mixed polyester melt. The ...

Embodiment 3

[0041] This embodiment describes a preparation method of ultra-fine denier absorbent and discharging icy antibacterial fiber. The "preparation of nano-icy jade powder micro-mixed polyester melt" adopted is inconsistent with that in Example 1, and the others are the same as in Example 1.

[0042] Preparation of micro-mixed polyester melt of nano-icy jade powder

[0043] After the nano-icy jade powder is dried and extruded and melted, it is measured by a metering pump at a mass content ratio of 1.0%, and then enters the spherical cavity-shaped high-efficiency dynamic mixer; the polyester melt prepared in step (1) is transported through the melt The pipeline is pressurized by the booster pump, the melt cooler, and the distribution valve are divided into the spinning box, and then enters the spherical cavity-shaped high-efficiency dynamic mixer to fully mix with the nano-icy jade powder to obtain a small amount of nano-icy jade powder Mixed polyester melt. The temperature of the spinn...

Abstract

The invention relates to the technical field of production of polyester fibers, in particular to a preparation method of a superfine denier moisture absorption and sweat release ice cool antibacterialfiber. The preparation method comprises the following steps: (1) preparing a polyester melt; (2) preparing a nanometer ice cool jade powder mixed with trace amount of the polyester melt; (3) preparing a cross-shaped cross section polyester fiber; and (4) winding and forming the polyester fiber. According to the preparation method of the obtained superfine denier moisture absorption and sweat release ice cool antibacterial fiber, a certain amount of the nanometer ice cool jade powder is added, so that the fiber achieves the antibacterial effect while the heat conductivity coefficient of the fiber is improved, and the fiber is mixed together with the cross-shaped cross section abnormal fiber, so that the fiber achieves the effects of transporting moisture, releasing sweat, cooling, and being antibacterial and bacteriostatic. In addition, the nanometer ice cool jade powder and a fiber-forming polymer are tightly combined, last permanently, and do not fall off even after the fiber is washed and worn for a long period of time, in addition, the superfine denier moisture absorption and sweat release ice cool antibacterial fiber is in contact with the skin for long, and has the effects ofimproving blood microcirculation, promoting metabolism, preventing diseases and eliminating fatigue.

Description

Technical field [0001] The invention relates to the technical field of polyester fiber production, in particular to a preparation method of ultrafine denier absorbent and icy antibacterial fiber. Background technique [0002] With the progress of society and the improvement of living standards, healthy and environmentally friendly new chemical fiber products are becoming more and more popular, and traditional, low-value-added chemical fiber products simply cannot adapt to the current development. Especially in the hot and humid summer, the high intensity of ultraviolet radiation threatens human health. People are in urgent need of multifunctional products that are refreshing and comfortable, moisture-absorbing, breathable, deodorizing and antibacterial while protecting themselves from ultraviolet rays. [0003] At present, the fibers with cooling function on the market mostly grind minerals into sub-micron powders, which are added as additives to the polymerization process to achi...
