Description

Fullerene composite fiber

Technical Field

The utility model belongs to the technical field of the fibre technique and specifically relates to a fullerene composite fiber.

Background

Fullerene is a hollow molecule composed entirely of carbon, and is in the shape of a sphere, ellipsoid, column or tube. Fullerene is used in facial masks and undergarments because of its excellent antioxidant properties. The existing fullerene composite fiber is usually formed by twisting and weaving a plurality of fibers compounded with fullerene, most of structures of the twisted fibers except the surface structure of the fibers are extruded inside, and the surface area is reduced, so that only a small amount of fullerene on the surface layer can play an anti-oxidation function, and the fullerene of the internal structure is difficult to play a role, thereby influencing the effect.

For example, a chinese patent document discloses "a method for preparing an antibacterial fiber cloth using fullerene", whose publication No. CN109629073A, comprising the steps of: respectively weighing antibacterial polyacrylonitrile fiber, modal fiber, bamboo fiber and polyester fiber according to the mass ratio of 2:3:2:3, wherein an antibacterial agent and water-soluble fullerene are arranged in the antibacterial polyacrylonitrile fiber; respectively carrying out blowing, coiling and cotton carding on the antibacterial polyacrylonitrile fibers, the modal fibers, the bamboo fibers and the polyester fibers, carrying out drawing, roving and spinning on the modal fibers, the bamboo fibers and the polyester fibers to obtain blended yarns, and carrying out drawing, roving and spinning on the antibacterial polyacrylonitrile fibers to obtain antibacterial polyacrylonitrile fiber yarns; and finally, carrying out refining treatment, weaving, washing, moisture absorption finishing and drying to obtain the antibacterial fiber fabric. The invention dissolves water-soluble fullerene in spinning solution, and carries out drawing after spinning, which has the defect that the fiber after drawing and twisting is compacted, so that the fullerene in the fiber is difficult to exert effect.

Disclosure of Invention

The utility model relates to an overcome current fullerene composite fiber fullerene utilization ratio and hang down, influence the problem of anti-oxidant effect, provide a fullerene composite fiber, increase fullerene utilization ratio improves anti-oxidant effect.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a fullerene composite fiber, includes core fibre and the cladding at the outer fibrous layer of core fibre outside, outer fibrous layer is twisted together by a plurality of outer fibrous spiral, core fibre and outer fibre all compound has the fullerene, core fibre diameter is 2~3 times of outer fibrous diameter.

The utility model is characterized in that the fiber is set into a double-layer structure, the middle core fiber plays a role in supporting and strengthening the outer fiber layer, and because the core fiber is 2-3 times thicker than the outer fiber layer, a larger space is formed between the adjacent outer fibers of the outer fiber layer, after the outer fiber layer is twisted, the outer fiber is extruded to the center of the core fiber, the core fiber is extruded to the space between the adjacent outer fibers after being pressed, the core fiber of the part is exposed, and because the core fiber is also compounded with fullerene, the fiber and the fullerene contained in the outer fiber play an anti-oxidation effect together; meanwhile, in the using process, the outer layer fiber and the core fiber can generate relative displacement, the extrusion part of the core fiber can be correspondingly changed after the core fiber is moved, the fullerene at other parts of the core fiber can be diffused, the function is exerted, and the fullerene utilization rate of the twisted fiber is improved.

Preferably, the core fiber is formed by compounding polyester fiber or polyamide fiber with fullerene.

The core body fiber made of the polyester fiber or the polyamide fiber has high strength and good elasticity, and can ensure the overall strength and stability of the fiber and the fabric.

Preferably, the weight ratio of the fullerene of the core fiber is 1% -3.5%.

The core fiber under the concentration has better antibacterial and antioxidant performance and durability.

Preferably, the outer layer fiber is formed by compounding one or more of silk fiber and bamboo fiber with fullerene.

A plurality of outer fiber layers are twisted to form an outer fiber layer, because the outer fiber layer is in direct contact with the skin, the silk fiber or the bamboo fiber has better skin-friendly performance and is suitable for making products with higher requirements on skin-friendly degree, such as underwear, and the like, and the outer fiber layer can be made of fibers of the same material and can also be formed by mixing and twisting fibers of different materials according to requirements.

Preferably, the weight ratio of the fullerene of the outer layer fiber is 1-3.5%.

The outer layer fiber under the concentration has better antibacterial and antioxidant performance and durability.

Preferably, the outer fiber layer is formed by spirally twisting three outer fibers.

The three outer layer fibers not only ensure that enough space is reserved between the adjacent fibers for extruding the core body fibers, but also ensure the strength of the outer fiber layer.

Preferably, the fullerene is C60.

The C60 type fullerene is easy to prepare and purify and has low cost.

Therefore, the utility model discloses following beneficial effect has: (1) the fullerene utilization rate is high, and the antioxidant effect is good; (2) the composite fiber has high strength and good stability; (3) the skin-friendly performance is good.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description.

In the embodiment shown in fig. 1 and 2, the fullerene composite fiber comprises a core fiber 1 and an outer fiber layer coated outside the core fiber 1, wherein the outer fiber layer is formed by spirally twisting three outer fiber layers 2, the outer fiber layer 2 comprises two silk fibers and one bamboo fiber, the silk fibers and the bamboo fiber are both compounded with 3% (weight) of C60 type fullerene, the core fiber is a polyester fiber compounded with 2% (weight) of fullerene, and the diameter of the core fiber 1 is 2 times of that of the outer fiber 2.

Under the normal state of the composite fiber, the surface area of the outer fiber layer is larger, the contact surface between the skin and the fullerene is increased, more fullerene can directly play an anti-oxidation role, and the fullerene utilization rate is high.

When the outer layer fibers 2 are extruded and shrunk inwards, the parts of the core fibers 1 of the inner layer, corresponding to the outer layer fibers 2, are extruded inwards, and the rest parts of the core fibers 1 are extruded out from gaps among the outer layer fibers 2, so that not only is the fullerene on the surface layer of the outer layer fibers utilized, but also the fullerene of the core fibers of the inner layer can directly play an anti-oxidation role after being extruded and exposed on the surface; meanwhile, in the using process, the outer layer fiber and the core fiber can generate relative displacement, the extrusion part of the core fiber can be correspondingly changed after the core fiber is moved, the fullerene at other parts of the core fiber can be diffused, the function is exerted, and the fullerene utilization rate of the twisted fiber is improved.

The core body fiber made of the polyester fiber has high strength, and the outer layer fiber has good skin-friendly property, and can be used for making facial masks, underwear and the like.
