Description

Technical Field

[0001] The invention belongs to the technical field of fiber materials, and in particular relates to a functional fiber for promoting microcirculation. Background Art

[0002] Polyester fiber, also known as polyester, is a kind of polymer compound with excellent wrinkle resistance and shape retention, high strength and elastic recovery ability. It is a very practical synthetic fiber and is widely used in the fields of textile and clothing manufacturing. After shaping, polyester fabric clothing has stable size and shape, good crispness and is not easy to shrink.

[0003] With the development of science and technology, promoting and applying new technologies in different fields in order to achieve new effects has become one of the mainstream research directions. The clothing field is no exception. For example, the multifunctional application of PET fiber is one of the research directions in the field of clothing materials at this stage. However, the current research directions of PET fiber materials mostly focus on the antibacterial properties, UV resistance or self-cleaning properties of the materials themselves, but ignore the fact that clothing made of PET fibers is ultimately worn on the body. How to enhance the beneficial effects of PET fiber clothing on the human body needs to become one of the directions for improving PET functions.

[0004] Microcirculation refers to the blood circulation between the human body's arterioles and venules. The most fundamental function of blood circulation is to exchange substances between blood and tissues, and microcirculation undertakes part of the substance exchange function. Improving and promoting microcirculation can enhance the body's metabolic capacity, help excrete toxic substances, and increase the body's ability to resist cold. The skin, as the largest organ of the human body, is distributed with numerous capillaries, and the skin is in direct contact with clothing. If the clothing is functionally improved to promote and improve the microcirculation of the body surface, it will be more beneficial to the health of the body. Therefore, it is necessary to design a functional fiber that can improve the microcirculation of the human body for the manufacture of clothing. Summary of the invention

[0005] The object of the present invention is to provide a functional fiber for promoting microcirculation to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0022] Figure 1 This is a functional masterbatch component diagram of the present invention. DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example:

[0025] See also Figure 1 As shown, a functional fiber for promoting microcirculation is prepared by melt spinning from a functional masterbatch, wherein the functional masterbatch comprises the following components:

[0026] 5-6 parts by weight of biological functional powder, wherein the biological functional powder is a powder prepared by mixing 99.87 parts by weight of animal bone powder, 0.1299 parts by weight of hydroxyphosphate and 0.0001 parts by weight of plant extract, wherein the plant extract may be seaweed extract or may be replaced with other plant extracts as required, and the particle size of the animal bone powder is 0.8-1.0 μm;

[0027] 93-95 parts by weight of polyethylene terephthalate;

[0028] 2-2.5 parts by weight of a dispersant, wherein the dispersant is ethylene bisstearamide.

[0029] From the above, it can be seen that before preparing the functional masterbatch, the biofunctional powder, polyethylene terephthalate and ethylene bisstearamide need to be mixed together. Ethylene bisstearamide as a dispersant can help the biofunctional powder and polyethylene terephthalate to be better mixed evenly.

[0030] The functional masterbatch preparation steps include:

[0031] The biofunctional powder, polyethylene terephthalate and dispersant are uniformly mixed according to the weight ratio to form a mixed powder raw material, which can be stirred using a high-speed mixer to ensure that the raw materials are fully and uniformly mixed;

[0032] The mixed powder raw material is transferred to a screw extruder, and the mixed powder raw material is heated and melted by electric heating;

[0033] Extrude the molten material, cool and shape it, and then cut it into pellets. It can be shaped by water cooling, and can be cut into polyester particles of different sizes by a strand pelletizer;

[0034] Finally, the cut particles are weighed and packaged to ensure that the weight and specifications of each product meet customer requirements. In addition, proofing may be required depending on customer needs.

[0035] The melting temperature of the mixed powder raw material is 285°C.

[0036] The melt spinning preparation steps include: heating and melting functional masterbatch, extruding the molten material from a spinneret to form a filament bundle, stretching the filament bundle for heat setting or bending setting, and shearing the set filament bundle to obtain a finished functional fiber.

[0037] As can be seen from the above, the biofunctional powder, polyethylene terephthalate and ethylene bisstearamide are first mixed together to form a mixed powder, the mixed powder raw material is transferred to a screw extruder, the raw material is melted and extruded for shaping, and the functional masterbatch is formed after pelletizing, and then the functional fiber is prepared by melt spinning.

[0038] Verification example:

[0039] In order to verify the microcirculation promoting function of functional fibers, a group of comparative tests were set up for verification. The subjects were adults over 18 years old, regardless of gender. The test instrument was BV-520 Ultrasonic Doppler blood flow detector. The test index was to improve microcirculation. The test site was limbs. The effects were judged based on the changes in the subjects before and after use in terms of enhancing human metabolism, improving microcirculation, accelerating blood circulation, etc. The test environment was a normal living environment. The purpose was to measure the functional new material fiber using human energy interaction as a carrier, which can achieve an increase in blood velocity through the touch of human limbs.

[0040] During the test, take an appropriate amount of functional fiber, cover the subject's right arm, tie it tightly with a rope, leave it for 4 to 5 minutes, tie it with white fiber cloth on the left arm, tie it tightly with a rope, leave it for 4 to 5 minutes, use BV-520 ultrasonic Doppler blood flow detector to measure the blood flow velocity of the subject's left and right arms respectively. The changes in the subject's blood flow velocity structure are shown in the following table:

[0041]

[0042]

[0043] As can be seen from the table above, the blood flow rate of the arm bound with functional fibers is significantly higher than that of the arm bound with white fiber cloth, indicating that the functional fiber cloth can significantly accelerate the blood flow rate of the subjects' limbs. In order to further verify the functionality of the functional fiber cloth, the functional fibers can be made into eye protection health eye masks, three-piece health beds or health quilts. The subjects use these products to compare whether the symptoms of the subjects are improved before and after the test, as shown in the table below:

[0044]

[0045]

[0046] As can be seen from the table above, after the subjects used these finished products made from functional behaviors, their physical discomfort symptoms were improved accordingly. This shows that functional fibers have auxiliary health care effects on enhancing human metabolism, accelerating blood circulation, and promoting health.
