Description
Technical Field
The invention belongs to the technical field of functional fiber materials, and particularly relates to far infrared antibacterial anti-mite anti-virus multifunctional fiber and a mattress protection pad.
Background
The far infrared fiber textile is a textile with functions of absorbing and emitting far infrared rays at normal temperature, the far infrared fiber is a novel fiber which is widely paid attention and put into production use in recent years, the far infrared fiber is prepared by adding a far infrared absorbent such as far infrared ceramic powder and the like in the fiber processing process, the far infrared fiber textile is a positive and efficient heat insulation material, and the radiated far infrared rays also have the effects of activating cell tissues, promoting blood circulation, inhibiting bacteria and deodorizing.
The antibacterial and mildewproof fiber is prepared by compounding an antibacterial material and a fiber material, has the functions of resisting bacteria, killing bacteria and preventing mildew, and can prevent infection and infection. The conventional preparation method comprises a mixing method and a post-treatment method. The mixing method is that inorganic antibacterial powder material containing silver, copper, zinc and other elements is mixed into polyester, polyamide, polyacrylonitrile and other materials for spinning; the post-treatment method is to dip the formed fiber material with quaternary ammonium salt antiseptic or fatty imide and other organic antiseptic.
The antiviral fiber is generally functional fiber obtained by treating an antiviral component through a mixing method or a post-treatment method, and the commonly adopted antiviral component is an antiviral component of a traditional Chinese medicine extracting solution, so that the antiviral fiber has the advantages of low cost, environmental friendliness and good antiviral effect.
In the preparation process of functional fibers, the technical problem generally existed is that the addition of functional materials has adverse effect on the strength and durability of the fibers, and the defect can be reduced by improving the dispersibility of the functional materials in the fiber matrix. In earlier researches of the applicant, better effects have been achieved by loading inorganic functional materials with silica aerogel microspheres (CN 114775095A) or by surface modification with porous silica and a silane coupling agent (CN 114808172A). However, the improvement of the dispersibility of the functional material has a limited effect on the strength and durability of the fiber, and thus, the strength and durability of the fiber are not satisfactory in products such as mattress protection pads.
In our earlier patent CN113652766B, a preparation method of a compound deodorizing antibacterial antiviral multifunctional fiber is disclosed, polyvinyl alcohol is used as a coating agent of a traditional Chinese medicine antiviral component and an organosilicon quaternary ammonium salt antibacterial agent to promote the mixing and dispersion of the traditional Chinese medicine antiviral component and the organosilicon quaternary ammonium salt antibacterial agent in a fiber matrix; meanwhile, an interpenetrating network is formed by hydrolysis and condensation reactions of silicate ester compounds and polyvinyl alcohol, so that antiviral components of the traditional Chinese medicine and the organosilicon quaternary ammonium salt antibacterial agent are further stabilized, and an enhanced structure is formed. The long-lasting deodorant antibacterial antiviral effect can be achieved and the fiber strength can be enhanced by introducing the antibacterial deodorant into a fiber matrix. The above patent technology provides a feasible idea for improving the strength and durability of the functional fiber. However, the above reinforcing structure has great difficulty in process control, and the product stability needs to be improved. Therefore, it is necessary to develop a fiber reinforced material which is easy to add and stably controlled.
The silicon rubber has excellent mechanical property, heat resistance, cold resistance, aging resistance and the like, and is widely applied, but the simple silicon rubber generally exists in an unchangeable thermosetting elastomer form, has low rigidity, cannot prepare a nano-scale powder product, has poor compatibility with a fiber material, has strong hydrophobic and oleophobic properties, and is difficult to form good dispersion in the fiber material in a simple melt mixing or solution mixing mode to achieve a reinforcing effect.
Disclosure of Invention
Aiming at the defects and shortcomings of the prior art, the invention mainly aims to provide a preparation method of far infrared antibacterial anti-mite antiviral multifunctional fiber.
The invention also aims to provide the far infrared antibacterial anti-mite antiviral multifunctional fiber prepared by the method.
The invention also aims to provide a mattress protection pad prepared by adopting the far infrared antibacterial, acarid-proof and antiviral multifunctional fiber.
The purpose of the invention is realized by the following technical scheme:
a preparation method of far infrared antibacterial anti-mite antiviral multifunctional fiber comprises the following preparation steps:
(1) Preparation of cation-modified silicone rubber reinforcing particles:
dissolving hydroxyl silicone oil into an organic solvent, adding fumed silica, stirring and dispersing uniformly, adding amino trimethoxy silane at the temperature of 50-80 ℃ under the conventional humid air condition (humidity is 35% -75%) for crosslinking reaction, then adding 2, 3-epoxypropyltrimethyl ammonium chloride for cationization reaction, and removing the organic solvent from the product through vacuum drying to obtain cation modified silicon rubber reinforced particles;
(2) Preparing far infrared antibacterial anti-mite antiviral multifunctional nanoparticles:

Further, the hydroxyl silicone oil in the step (1) is low molecular weight hydroxyl silicone oil with the viscosity (25 ℃) of 50-500 cst; the organic solvent is isopropanol, benzene or toluene. Too high molecular weight of the hydroxyl silicone oil leads to insufficient crosslinking density, reduced reactivity, and adhesion between the silicone rubber reinforcing particles, and reinforcing particles with good dispersibility cannot be obtained.
Further, the adding amount of the fumed silica in the step (1) is 5-20% of the mass of the hydroxyl silicone oil. The fumed silica is added to play a role in strengthening and nucleating, and the particle size of the silicon rubber reinforced particles is controlled, so that the silicon rubber reinforced particles can be conveniently added into a fiber matrix to achieve a strengthening effect.

If the addition amount of the amino trimethoxy silane is too low, the crosslinking degree is not enough, adhesion is generated among silicon rubber reinforced particles, and reinforced particles with good dispersion performance cannot be obtained; an excessively high amount of aminotrimethoxysilane added leads to an increase in cost.
Further, the adding amount of the 2, 3-epoxypropyltrimethylammonium chloride in the step (1) is 0.5-1 time of the molar amount of the aminotrimethoxysilane. According to the invention, the cationization is carried out by utilizing the ring-opening reaction of the amino group of the amino trimethoxy silane and the 2, 3-epoxypropyltrimethyl ammonium chloride, the excessive monomer is difficult to remove due to the excessively high addition amount of the 2, 3-epoxypropyltrimethyl ammonium chloride, the cationization degree is insufficient due to the excessively low addition amount, and the dispersibility and the reinforcing effect of the obtained silicon rubber reinforced particles are reduced.
Further, the nano far infrared powder in the step (2) is at least one of far infrared ceramic powder, taiji stone powder, vermiculite raw ore powder, medical stone raw ore powder, nano zirconium dioxide powder and nano manganese oxide powder; the nano antibacterial and anti-mite powder is at least one of silver oxide powder, lanthanum oxide powder, zinc oxide powder, titanium dioxide powder, copper oxide powder, magnesium oxide powder and silver iodide powder.

Further, the ratio of the total mass of the nano far infrared powder and the nano antibacterial and anti-mite powder in the step (2) to the mass of the silica sol is 1 to 4.
Furthermore, the silane coupling agent in the step (2) refers to a silane coupling agent containing carboxyl (such as 3- [ 3-carboxyl allylamido ] propyl triethoxysilane) or a silane coupling agent containing amino (such as aminopropyl trimethoxysilane, aminoethyl aminopropyl trimethoxysilane, aminopropyl triethoxysilane, aminoethyl aminopropyl triethoxysilane and the like), and the adsorption effect of the porous material obtained by surface modification of the silane coupling agent containing active groups on the traditional Chinese medicine antiviral active ingredients is better; the adding amount of the silane coupling agent is 0.1-5% of the mass of the silica sol.
Further, the antiviral extract of the traditional Chinese medicine in the step (2) comprises an extract of at least one traditional Chinese medicine component selected from wormwood, radix isatidis, dandelion, honeysuckle, wild chrysanthemum flower, folium isatidis, andrographis paniculata, scutellaria baicalensis, coptis chinensis, phellodendron amurense, radix bupleuri, cyrtomium rhizome, fructus forsythiae, polygonum cuspidatum, blackberry lily, rheum officinale, houttuynia cordata, elsholtzia, eupatorium, cacumen biotae, rhizoma polygonati, schisandra chinensis, burdock, radix sileris, perilla frutescens, verbena, rabdosia rubescens, sophora flavescens, radix scrophulariae, solanum dulcamara, fructus kochiae, indian mockstrawberry herb, bezoar, lithospermum, pericarpium citri reticulatae, ageratum and mint.
Further, the adsorption treatment in the step (2) is carried out under the conditions of ultrasound and vacuum stirring, and the adsorption treatment time is 0.5-4 h.

Compared with the prior art, the invention has the beneficial effects that:
(1) According to the invention, the fiber matrix is reinforced by the cation modified silicon rubber reinforced particles prepared by a specific method, and a nano-scale product cannot be prepared from a conventional silicon rubber material due to low rigidity, and the cation modified silicon rubber reinforced particles have poor compatibility with a fiber material, have strong hydrophobic and oleophobic properties, are difficult to form good dispersion in the fiber material in a simple melt mixing or solution mixing manner, and achieve a reinforcing effect. The invention takes the gas-phase silicon dioxide as a particle nucleating agent and a reinforcing agent, can obtain nano-scale silicon rubber reinforced particles through specific crosslinking and cationization reaction, and can obviously improve the mechanical property and the aging resistance of a fiber material by verification.

TABLE 1
The results in table 1 show that the mechanical strength and the aging resistance of the fiber material can be significantly improved, and particularly the aging resistance can be significantly improved by adding the cationic modified silicone rubber reinforcing particles of the present invention into the fiber matrix.
Example 2
The preparation method of the far infrared antibacterial anti-mite antiviral multifunctional polyester fiber comprises the following preparation steps:
(1) Preparation of cation modified silicone rubber reinforced particles:
according to parts by weight, 100 parts of hydroxyl silicone oil with the viscosity (25 ℃) of 50cst, 100cst, 200cst, 500cst and 1000cst is dissolved in isopropanol, 10 parts of fumed silica is added, the mixture is uniformly stirred and dispersed, the system is heated to 65-75 ℃, 6 parts of aminoethyl aminopropyl trimethoxy silane is added for crosslinking reaction for 1.5h (the reaction is carried out under the condition of normal humidity and air), 2, 3-epoxypropyl trimethyl ammonium chloride with the molar weight of 0.8 time of that of the aminoethyl aminopropyl trimethoxy silane is added for cationization reaction for 3h, and after the reaction is finished, the product is dried in vacuum to remove the solvent, so that the cation modified silicone rubber reinforced particles are obtained.

The morphology and D90 particle diameter of the silicone rubber reinforced particles obtained from the hydroxyl silicone oil with different viscosities of the embodiment were tested, and the mechanical strength of the obtained multifunctional polyester fiber was tested, and the results are shown in Table 2 below.
TABLE 2
| Viscosity of hydroxy silicone oil | 50cst | 100cst | 200cst | 500cst | 1000cst |
| Morphology and particle size | 310nm | 380nm | 430nm | 950nm | Adhesive ball |
| Breaking strength | 5.5cN/dtex | 6.0cN/dtex | 6.3cN/dtex | 6.6cN/dtex | ---- |
| Elongation at break | 42％ | 55％ | 59％ | 61％ | ---- |
As can be seen from the results in table 2, the reinforcing effect of the obtained silicone rubber reinforcing particles is enhanced as the viscosity (molecular weight) of the hydroxy silicone oil is increased, but too high viscosity of the hydroxy silicone oil causes a decrease in reactivity and insufficient crosslinking density, and adhesive agglomerates are generated between the silicone rubber reinforcing particles, and reinforcing particles having good dispersibility cannot be obtained.
Example 3
The preparation method of the far infrared antibacterial anti-mite antiviral multifunctional polyester fiber comprises the following preparation steps:
(1) Preparation of cation-modified silicone rubber reinforcing particles:
according to parts by weight, 100 parts of hydroxyl silicone oil with the viscosity (25 ℃) of 120cst is dissolved in isopropanol, 10 parts of fumed silica is added and uniformly stirred, the system is heated to 65-75 ℃, 6 parts of aminoethyl aminopropyl trimethoxy silane is added to carry out crosslinking reaction for 1.5h (the reaction is carried out under the condition of normal humidity and air), then 0 time, 0.3 time, 0.5 time, 0.6 time, 0.7 time, 0.9 time and 1.0 time of the molar weight of the aminoethyl aminopropyl trimethoxy silane are respectively added to carry out cationization reaction for 3h, and after the reaction is finished, the product is dried in vacuum to remove the solvent, so that the cation modified silicon rubber reinforced particles are obtained.
(2) The preparation of the far infrared antibacterial anti-mite antiviral multifunctional nano particles is the same as that of the example 1.
(3) Preparing a multifunctional fiber material:
and (3) melting, blending and spinning 8 parts by mass of the cation modified silicone rubber reinforced particles obtained in the step (1), 10 parts by mass of the far infrared antibacterial, anti-mite and antiviral multifunctional nano particles obtained in the step (2) and 100 parts by mass of the polyester chips through an extruder to obtain the far infrared antibacterial, anti-mite and antiviral multifunctional polyester fiber.
The morphology and D90 particle diameter of the silicone rubber reinforcing particles obtained by the different cationization degrees of this example were tested, and the mechanical strength of the obtained multifunctional polyester fiber was tested, and the results are shown in table 3 below.
TABLE 3
| Amount of cation added | 0 | 0.3 times of | 0.5 times of | 0.6 times of | 0.7 times of | 0.9 times of | 1.0 times of |
| Particle size | 880nm | 550nm | 430nm | 180nm | 140nm | 90nm | 80nm |
| Breaking strength | 4.8cN/dtex | 5.4cN/dtex | 5.5cN/dtex | 5.7cN/dtex | 5.8cN/dtex | 6.2cN/dtex | 6.3cN/dtex |
| Elongation at break | 39％ | 49％ | 51％ | 54％ | 54％ | 61％ | 60％ |
The results in table 3 show that the cationization degree has a significant effect on the particle size and the reinforcing effect of the obtained silicone rubber reinforcing particles, and the reason is that the higher the cationization degree is, the larger the electrostatic repulsion force of the silicone rubber reinforcing particles in the preparation and nucleation process is, the lower the degree of the cohesive groups among the particles, so that the particle size is reduced, and meanwhile, the agglomeration is reduced in the process of blending and spinning with the fiber material, so that the dispersion performance of the silicone rubber reinforcing particles in the fiber material is finally improved, and the better effect of reinforcing the mechanical property is achieved. When cation modification is not adopted, the particle size of the silicon rubber reinforced particles is increased, and the reinforcing effect on the fiber material is obviously reduced, because the compatibility between the silicon rubber particles which are not modified by the cation and the fiber base material is poor, and obvious agglomeration tendency exists, so that the reinforcing effect is reduced.
