Description

TECHNICAL FIELD

[0001] The present application relates to the wig material technical field, and specifically discloses a kind of composite fiber material and its preparation method and application. BACKGROUND

[0002] With the improvement of people's living standards and consumption level, and the pursuit of individuality and fashion, wig products have become an important accessory in modern life, with broad market demand.

[0003] With the increasing market demand for wigs, the production scale of artificial wigs is increasing. Wigs can be divided into chemical fiber wig and real hair wig according to the material. Among them, chemical fiber hair is a hair product made of one or more chemical fibers. Because the chemical fiber is bright, it has poor realism, and it is easy to have an allergic reaction such as itching after wearing, which is not good for human health, and the chemical fiber is flammable, and the organic matter formed during combustion is easy to cause burns to the human body, which poses a threat to personal safety. In addition, chemical fiber is a synthetic fiber, most of which is a petrochemical product, which is a non-renewable resource and is difficult to degrade in the natural environment after being discarded, polluting the environment and failing to meet people's demand for green and environmental protection. However, chemical fiber hair is cheap and has good curling firmness; real hair is made of real human hair after bleaching and dyeing treatment, and has the characteristics of high realism and difficulty in knotting. It can be oiled and dyed later, but due to the lack of raw materials, the price of human hair products is very high, and the setting effect and curling firmness are not as good as chemical fiber hair.

[0004] Therefore, it is necessary to develop a wig fiber material that has good skin affinity, high realism, low cost, certain flame retardant effect and meets the concept of green and environmental protection to meet market demand. SUMMARY

[0005] In view of the poor realism, poor skin affinity, high cost, safety hazards and environmental pollution of the existing wig materials, the present application provides a composite fiber material and its preparation method and application. The composite fiber material includes an inner core and a connecting layer and a surface coating layer successively coated outside the inner core from inside to outside. The inner core is connected to the surface coating layer in the form of a chemical bond after being modified by the connecting layer to obtain the composite fiber material. The wig prepared from the composite fiber material has good affinity with human skin, good flame retardancy, a hand feel similar to real hair, and the composite fiber material is degradable, does not pollute the environment, and meets the concept of green and environmental protection.

[0006] To achieve the above-mentioned application purposes, the present application adopts the following technical solutions:

[0007] The first aspect of the present application provides a kind of composite fiber material, the composite fiber material includes inner core, and the connecting layer and surface coating layer covered in the outer of the inner core in turn from inside to outside, the inner core is inorganic mineral fiber, the raw material of the connecting layer is amino silane coupling agent, and the raw material of the surface coating layer is natural macromolecular fiber protein.

[0008] Compared with the prior art, the application creatively proposes a new composite fiber material, which uses inorganic mineral fiber as the inner core, natural macromolecular fiber protein as the surface coating layer, and amino silane coupling agent as the connecting layer between the inner core and the surface coating layer. There are a large number of Si(OH)4 on the surface of the inorganic mineral fiber. After modification by the amino silane coupling agent, the hydroxyl groups in the coupling agent molecules can undergo dehydration reaction with the hydroxyl groups on the surface of the inorganic mineral fiber to form a firm surface modification layer. The exposed amino groups on the surface of the modification layer react with the carboxyl groups in the natural macromolecular fiber protein molecules to form N=C chemical bonds, which tightly connect the natural macromolecular fiber protein and the inorganic mineral fiber in the form of chemical bonds to generate a composite fiber material with high interfacial strength. The specific reaction process is shown below.

[0009]

[0010] Compared with organic fibers, inorganic mineral fibers have the advantages of high reserves, low cost, excellent flame retardant performance and high temperature resistance, and are free of harmful organic substances such as aromatic amines and formaldehyde, thus being safer. However, inorganic mineral fibers have poor hand feeling, low softness and low gloss. To solve this problem, the inventors modify the inorganic mineral fibers with an amino silane coupling agent and then combine them with natural macromolecular fiber protein, so that the natural macromolecular fiber protein tightly covers the inorganic mineral fibers, thereby greatly improving the hand feeling, softness and gloss of the obtained composite fiber material. The wig products prepared from the composite fiber material not only have excellent flame retardant performance and skin-friendly performance, but also have higher realism and are closer to human hair.

[0011] Preferably, the inorganic mineral fiber is basalt continuous fiber.

[0012] Basalt has abundant reserves, low cost, produces less waste during production, and can be directly degraded in the environment without any harm, making it a truly green and environmentally friendly material.

[0013] Preferably, the amino silane coupling agent is of type KH-550.

[0014] Preferably, the natural macromolecular fiber protein is silk fibroin.

[0015] The second aspect of the present application provides a preparation method of the composite fiber material, which at least includes the following steps:

[0016] Step one, add natural high molecular fiber protein into deionized water, mix uniformly, and obtain natural high molecular fiber protein solution;

[0017] Step two, dissolve amino silane coupling agent into alcohol solution, and obtain amino silane coupling agent solution;

[0018] Step three, immerse inorganic mineral fiber into the amino silane coupling agent solution and the natural high molecular fiber protein solution in sequence, irradiate, and dry, and obtain semi-finished composite fiber material;

[0019] Preferably, the natural high molecular fiber protein is silk fibroin lyophilized powder.

[0020] Silk fibroin is mainly composed of random alpha-helix structure, thus, the silk fibroin can be dissolved in water.

[0021] Preferably, in step one, the mass concentration of the natural high molecular fiber protein is 2%-25%.

[0022] Preferably, in step two, the volume ratio of the amino silane coupling agent to the alcohol solution is 2-19:60-90.

[0023] Preferably, in step two, the alcohol solution is 45%-75% ethanol solution in mass concentration.

[0024] Preferably, in step three, the immersion time of the inorganic mineral fiber in the amino silane coupling agent solution is 5s-10s.

[0025] Preferably, the immersion time of the inorganic mineral fiber in the natural high molecular fiber protein solution is 20s-30s.

[0026] The inorganic mineral fiber provided by the present application only needs to be completely immersed in the amino silane coupling agent solution and the natural high molecular fiber protein solution, and the operation is simple and the operation time is short.

[0027] Preferably, in step three, the operation of irradiation is to irradiate the immersed inorganic mineral fiber by using a 254nm ultraviolet lamp.

[0028] Further preferably, the irradiation time is 0.5h-1.5h.

[0029] After the composite fiber material is irradiated by the ultraviolet lamp, the alpha-helix structure in the natural high molecular fiber protein is modified into beta-sheet structure, thus, the composite fiber material is insoluble in water, and the performance is more stable, and the obtained composite fiber material can be observed that transparent hard colloid state protein is connected to the surface of the inorganic mineral fiber.

[0030] Preferably, in step three, the drying temperature is 30℃-40℃, and the drying time is 30min-60min.

[0031] The third aspect of the present application provides a wig material made of the composite fiber material.

[0032] The inorganic mineral fiber and the natural polymer fiber protein in the wig material are both natural raw materials, green, environmentally friendly, non-polluting, non-toxic and harmless, and abundant in resources. Moreover, both of them are degradable, the inorganic mineral fiber can be degraded into soil, and the natural polymer fiber protein can be completely biodegraded, so the prepared wig material will not pollute the environment and meet the requirements of green environmental protection.

[0033] Preferably, the wig material is a golden wig.

[0034] The inorganic mineral fiber provided by the present application has a natural golden luster, and the prepared wig material is golden without dyeing treatment.

[0035] The present application provides a composite fiber material, a preparation method and application thereof. The composite fiber material is prepared by modifying the inorganic mineral fiber with an amino silane coupling agent and then combining the natural polymer fiber protein. The wig prepared by using the composite fiber material has good affinity with human skin, good flame retardancy, and a hand feel similar to real hair. Moreover, the inorganic mineral fiber and the natural polymer fiber protein used in the present application are both degradable, which does not pollute the environment and meets the concept of green environmental protection. The present application effectively solves the problems of poor realism, uncomfortable wearing effect, safety hazards and environmental pollution in the prior art. DETAILED DESCRIPTION
