Description
Technical Field
The invention relates to a silver-containing antibacterial liquid composition, a preparation method and application thereof.
Background
With the importance of people for healthy life, mattress cloth with antibacterial property is widely paid attention to by people. Silver ions have antibacterial ability and are commonly used in the prior art to perform antibacterial modification on fabrics. For example, CN115302874A discloses a blended antibacterial fabric containing silver ion modified fibers by utilizing the antibacterial property of silver ions, CN217744176U discloses a deodorizing antibacterial towel using the silver-containing fabric, and CN115287896a discloses a preparation method of an antibacterial biomass-based fabric by utilizing the antibacterial property of silver ions. However, silver ion-containing fabrics generally suffer from poor color stability.
Disclosure of Invention
The invention aims to solve the problem that the color of a fabric becomes serious due to the fact that the traditional silver-containing antibacterial agent is used for antibacterial finishing of the fabric, and provides a novel silver-containing antibacterial liquid composition which reduces the degree of color change of the antibacterial fabric after being used for antibacterial finishing of the fabric and has good color stability.
In order to solve one of the technical problems, the technical scheme of the invention is as follows:
a silver-containing antimicrobial liquid composition comprising, by weight:
positive monovalent Ag,1 part;
3-10 parts of ammonia;
0 to 80 parts of C1-C3 alcohol;
0-80 parts of water-soluble polymer;
SiO 2 colloidal particles, 0-80 parts;
and water so that the total part of the silver-containing antibacterial liquid composition is 500-2000 parts.
As non-limiting examples, ammonia is 3.5 parts, 4 parts, 4.5 parts, 5 parts, 5.5 parts, 6 parts, 6.5 parts, 7 parts, 7.5 parts, 8 parts, 8.5 parts, 9 parts, 9.5 parts, and the like.
In the above embodiments, the alcohol is preferably more than 0 part and 80 parts or less, more preferably 20 to 80 parts.
The C1-C3 alcohol reduces the severity of the color change of the antibacterial fabric after the antibacterial finishing of the fabric, and improves the color stability of the antibacterial fabric.
By way of non-limiting example, the C1-C3 alcohols are 5 parts, 10 parts, 15 parts, 20 parts, 25 parts, 30 parts, 35 parts, 40 parts, 45 parts, 50 parts, 55 parts, 60 parts, 65 parts, 70 parts, 75 parts, and the like. By way of comparison only, 10 parts, 30 parts or 40 parts are generally employed in the examples and comparative examples.
In the above technical solution, preferably, the alcohol includes at least one selected from the group consisting of methanol, ethanol, ethylene glycol, n-propanol, isopropanol, and glycerol.
In particular, the alcohols include both ethanol and glycerol, and it has been found that ethanol as a monohydric alcohol and glycerol as a trihydric alcohol have a mutual promoting effect in reducing the degree of color change of the antimicrobial fabric or improving the color stability of the antimicrobial fabric, and this promoting effect, according to the related work we have carried out, is not found between different polyols, between monohydric alcohols and dihydric alcohols, between different dihydric alcohols. The weight ratio of glycerol to ethanol in this case is not particularly limited, for example, but not limited to, 0.1 to 10, and as a more specific non-limiting example, the weight ratio of glycerol to ethanol is 0.2, 0.4, 0.8, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, and the like.
In the above embodiments, the water-soluble polymer is preferably more than 0 part and 80 parts or less, more preferably 10 to 40 parts.
The water-soluble polymer increases the color stability of the antimicrobial fabric.
By way of non-limiting example, the water-soluble polymer is 5 parts, 10 parts, 15 parts, 20 parts, 25 parts, 30 parts, 35 parts, 40 parts, 45 parts, 50 parts, 55 parts, 60 parts, 65 parts, 70 parts, 75 parts, and the like. By way of comparison only, 24 parts or 58 parts are generally employed in the examples and comparative examples.
In the above technical solution, preferably, the water-soluble polymer includes at least one selected from the group consisting of carboxymethyl cellulose salt, polyvinyl alcohol, polyethylene glycol, polyvinylpyrrolidone, polyacrylamide, polymethacrylamide, polyacrylate, polymethacrylate, polyethyleneimine, and a copolymer obtained by copolymerizing at least two of the group consisting of vinylpyrrolidone, acrylamide, methacrylamide, acrylate, methacrylate, and vinylimidazole.
The molecular weight of the polymer is not particularly limited as long as it is a water-soluble polymer, and comparable effects of stabilizing the composition can be obtained. Particularly, the effect of stabilizing the composition is more excellent when the water-soluble polymer contains a coordinating atom for forming a coordinate bond with positive monovalent Ag. These coordinating atoms may be heteroatoms such as N, O. Merely by way of comparison, in the examples of the present invention, the water-soluble polymer is represented by polyethyleneimine. Similarly, the molecular weight of the polyethyleneimine is not particularly limited, and comparable effects of stabilizing the composition can be obtained. As known to those skilled in the art, polyethyleneimines are obtained by homopolymerization of ethyleneimines (also known as ethyleneimines, etc.), which have primary, secondary and tertiary amino groups in their structure.
For example, but not limited to, polyethyleneimine has a weight average molecular weight (as measured by light scattering) of 500 ～ 2,000,000 (e.g., but not limited to, 1,000, 1,500, 2,000, 2,500, 3,000, 3,500, 4,000, 4,500, 5,000, 8,000, 10,000, 15,000, 20,000, 25,000, 30,000, 50,000, 100,000, 150,000, 200,000, 250,000, 300,000, 500,000, 800,000, 1,000,000, 1,500,000, 2,000,000, etc.), but more preferably 500 to 10000, still more preferably 500 to 5,000, and the effect of improving the color stability of the antibacterial fabric becomes insignificant compared to a molecular weight too large.
In the polyethyleneimine molecule, primary amino: secondary amino: tertiary amino=1:a: b, wherein a is 0.8 to 1.2 (e.g., but not limited to, a is 0.85, 0.9, 0.95, 1.0, 1.05, 1.1, 1.15, etc.), b is 0.4 to 0.8 (e.g., but not limited to, b is 0.45, 0.50, 0.55, 0.6, 0.65, 0.7, 0.75, etc.), on a molar basis, are preferred.
Polyethyleneimine is available from commercial sources. Examples of the specification of polyethylenimine from BASF are:
LUPASOL FG (weight average molecular weight 800, a is 0.82, b is 0.53),
LUPASOL G20 wfr (weight average molecular weight 1300, a 0.91, b 0.64),
LUPASOL PR8515 (weight average molecular weight 2000, a 0.92, b 0.70),
LUPASOL FC (weight average molecular weight 800, a 0.86, b 0.42, 50% water),
LUPASOL G20 (weight average molecular weight 1300, a 0.91, b 0.64, containing 50% water),
LUPASOL G35 (weight average molecular weight 2000, a 0.94, b 0.67, containing 50% water),
LUPASOL G100 (weight average molecular weight 5000, a 1.05, b 0.76, containing 50% water).
By way of comparison only, the water-soluble polymers of the examples and comparative examples of the present invention each used LUPASOL PR8515 from BASF.
In the technical proposal, siO 2 The colloidal particles are preferably more than 0 part and 80 parts or less, more preferably 10 to 50 parts;
SiO 2 the use of colloidal particles reduces the degree of color change of the antibacterial fabric and improves the color stability of the antibacterial fabric.
By way of non-limiting example, siO 2 The colloidal particles are 5 parts, 10 parts, 15 parts, 20 parts, 25 parts, 30 parts, 35 parts, 40 parts, 45 parts, 50 parts, 55 parts, 60 parts, 65 parts, 70 parts, 75 parts, etc. Only by comparison, 34 parts or 58 parts are commonly used in examples and comparative examples.
More preferably, both polyethyleneimine and SiO are included in the composition 2 Colloidal particles, polyethylenimine and SiO 2 The colloidal particles have interaction in reducing the degree of color change of the antibacterial fabric or in improving the color stability of the antibacterial fabric. At this time, polyethyleneimine and SiO 2 The weight ratio of the colloidal particles is not particularly limited, and comparable interaction effects can be obtained, such as but not limited to polyethyleneimine and SiO 2 The weight ratio of the colloidal particles is 0.1 to 10, more specific non-limiting examples are 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, etc.
By way of non-limiting example, water such that the total parts of the silver-containing antimicrobial liquid composition are 550 parts, 600 parts, 650 parts, 700 parts, 750 parts, 800 parts, 850 parts, 900 parts, 950 parts, 1000 parts, 1050 parts, 1100 parts, 1150 parts, 1200 parts, 1250 parts, 1300 parts, 1350 parts, 1400 parts, 1450 parts, 1500 parts, 1550 parts, 1600 parts, 1650 parts, 1700 parts, 1750 parts, 1800 parts, 1850 parts, 1900 parts, 1950 parts, etc., are merely the same, and 1000 parts are commonly used in examples and comparative examples.
The second technical problem to be solved by the invention is a preparation method of the silver-containing antibacterial liquid combination. In order to solve the technical problem, the technical scheme of the invention is as follows:
the preparation method of the composition according to any one of the technical solutions of the above technical problems includes:
(1) Obtaining a dispersion solvent comprising ammonia, optionally a C1-C3 alcohol, optionally a water-soluble polymer and optionally SiO 2 A liquid mixture 1 of colloidal particles;
(2) Obtaining a positive monovalent silver compound aqueous solution;
(3) An aqueous solution of a positive monovalent silver compound was added to the liquid mixture 1.
For the water required in the silver-containing antimicrobial liquid composition, those skilled in the art understand that the entire water distribution can be used in step (1) and step (2); part of the water can be distributed and used in the step (1) and the step (2) firstly, and then the required amount of water is replenished after the step (3); etc. In this way, comparable technical effects can be achieved without the need for creative efforts.
In the above-described technical scheme, ammonia is preferably used as the raw material of the liquid mixture 1 in the form of aqueous ammonia.
In the technical proposal, siO 2 The colloidal particles are used as a raw material of the liquid mixture 1 in the form of a silica sol.
In order to improve the storage stability of silica sol, there are two main types of silica sol (i.e., silica sol added with a small amount of alkaline substance as a stabilizer, sodium-stabilized silica sol, potassium-stabilized silica sol, and ammonia-stabilized silica sol are common) and acidic silica sol, and both of the two main types of silica sol can be used and can achieve comparable technical effects, but since acidic silica sol is acidic, ammonia in the composition is consumed, and from the viewpoint of saving material consumption, alkaline silica sol is preferred.
In the above technical solution, preferably, the alkaline silica sol is selected from sodium-stabilized silica sol, potassium-stabilized silica sol or ammonia-stabilized silica sol.
As a mere comparison, the silica sol used in the examples was Levasil CS400-222 silica sol from Noleon, which has a silica content of 40% by weight and a pH of 9.8, and was a sodium stabilized silica sol, na 2 The O content was 0.42w%.
The third technical problem to be solved by the invention is the application of the silver-containing antibacterial liquid composition, and in order to solve the technical problem, the technical scheme of the invention is as follows:
use of a composition according to any one of the above technical solutions or a composition obtained by a preparation method according to any one of the above technical solutions or according to any one of the above technical solutions in the antimicrobial finishing of textiles or in the antimicrobial finishing of textiles.
The technical key of the present invention is the components of the silver-containing antimicrobial liquid composition, which can be used by those skilled in the art for fabric finishing in combination with conventional methods after the components of the composition are determined. Such as, but not limited to:
firstly, preparing the silver-containing antibacterial liquid composition into a fabric antibacterial finishing liquid according to the following formula:
An antimicrobial finish for fabrics comprising, by weight:
(a) The liquid composition according to any one of the above technical problems, 100 parts;
(b) 0-20 parts of cross-linking agent; more preferably 5 to 20 parts;
(c) The water makes the total part of the antibacterial finishing liquid of the fabric 1000-5000 parts, more preferably 1500-3000 parts.
In the technical scheme, the cross-linking agent is not an essential component, and the comparable technical effect of the invention can be achieved by adding or not adding the cross-linking agent, but the cross-linking agent can increase the bonding fastness between Ag and the fabric in the process of fabric finishing by using the fabric antibacterial finishing liquid. The crosslinking agent may be a thermally crosslinkable crosslinking agent or a photocrosslinking crosslinking agent. As the name suggests, the crosslinking agent of the thermally crosslinkable type is a crosslinking agent which forms a three-dimensional network structure by a heat treatment process and then plays a crosslinking role, and the crosslinking agent of the photocrosslinking type is a crosslinking agent which forms a three-dimensional network structure by a light treatment process and then plays a crosslinking role. Examples of the thermally crosslinkable crosslinking agent that can be used in the present invention include, but are not limited to, polyacrylic crosslinking agents (i.e., crosslinking agents having a polyacrylic acid skeleton in the molecular structure of the crosslinking agent), polyurethane crosslinking agents (i.e., crosslinking agents having a polyurethane skeleton in the molecular structure of the crosslinking agent), amide-formaldehyde crosslinking agents (i.e., crosslinking agents having an amide-formaldehyde resin skeleton in the molecular structure of the crosslinking agent), urea-formaldehyde crosslinking agents (i.e., crosslinking agents having a urea-formaldehyde resin skeleton in the molecular structure of the crosslinking agent), and polycarboxylic acid crosslinking agents.
The thermally crosslinkable crosslinking agents used in examples and comparative examples are the same, and further, the thermally crosslinkable crosslinking agents used in examples and comparative examples are JYK FIX-DI crosslinking agents of Shanghai Jieykang chemical Co., ltd. JYK FIX-DI is the polyurethane cross-linking agent (namely, the cross-linking agent taking polyurethane as a framework in the molecular structure of the cross-linking agent). Suitable for preparing textile coating and foam coating sizing; the combination can improve wet rubbing fastness in pigment printing paste. Can also be used in functional auxiliary agents for improving the washing resistance of functional finishing. The JYK FIX-DI has good compatibility with various functional assistants, can be mixed with deionized water in any proportion, and can be treated for 2-5 minutes at 130-150 ℃. As a general rule, the higher the temperature, the shorter the heat treatment time required, based on which a person skilled in the art can reasonably adjust the heat treatment temperature and the heat treatment time, both of which can achieve the technical effects without having to make creative efforts.
In the above technical scheme, as non-limiting examples, the parts of the cross-linking agent are 3 parts, 4 parts, 5 parts, 6 parts, 7 parts, 8 parts, 9 parts, 10 parts, 11 parts, 12 parts, 13 parts, 14 parts, 15 parts, 16 parts, 17 parts, 18 parts, 19 parts, and the like. The parts generally used for the crosslinking agents in examples and comparative examples are only 10 parts by comparison.
As a non-limiting example, component (c) water is such that the total parts of the fabric antimicrobial finish are 1100 parts, 1200 parts, 1300 parts, 1400 parts, 1500 parts, 1600 parts, 1700 parts, 1800 parts, 1900 parts, 2000 parts, 2100 parts, 2200 parts, 2300 parts, 2400 parts, 2500 parts, 2600 parts, 2700 parts, 2800 parts, 2900 parts, 3000 parts, 3100 parts, 3200 parts, 3300 parts, 3400 parts, 3500 parts, 3600 parts, 3700 parts, 3800 parts, 3900 parts, 4000 parts, 4100 parts, 4200 parts, 4300 parts, 4400 parts, 4500 parts, 4600 parts, 4700 parts, 4800 parts, 4900 parts, and the like, just as the same, 2000 parts are commonly used in the examples and comparative examples of the present invention.
In the case of the above disclosed antibacterial finishing liquid components, the preparation method of the antibacterial finishing liquid is not particularly limited, and comparable technical effects can be obtained. For example, in the case where the crosslinking agent is water-soluble or water-dispersible, it is only necessary to dissolve or disperse the crosslinking agent into the component (a) and then supplement the water required for the component (c).
Then, the obtained fabric antibacterial finishing liquid is used for manufacturing antibacterial fabrics, and the manufacturing method of the antibacterial fabrics can be as follows:
a method of making an antimicrobial fabric comprising:
(i) Contacting the raw fabric with the fabric antibacterial finishing liquid according to any one of the technical schemes to obtain a fabric with liquid;
(ii) Drying to obtain a fabric b;
(iii) Baking to obtain the antibacterial fabric.
In the above technical solution, the contact mode in the step (i) is not particularly limited, and may be dip contact, spray contact, roll contact.
In the above technical solution, the contact mode in the step (i) is, by way of example only, impregnation contact, the contact time is not particularly limited, as long as the contact between the fabric deodorant finishing liquid and the fabric reaches or basically reaches equilibrium, and the contact time is prolonged without particularly affecting the technical effect, but the contact time is too long to cause the increase of the production time cost, and the contact time is too short to affect the load capacity of the photocatalyst, based on the principle of the contact time, the person skilled in the art can comprehensively consider the factors to reasonably select the impregnation time, and can obtain comparable technical effect without creative labor.
For example, but not limited to, a time of no less than 1 minute, further non-limiting examples of the time of impregnation may be 2 minutes, 3 minutes, 4 minutes, 5 minutes, 6 minutes, 7 minutes, 8 minutes, 9 minutes, 10 minutes, 11 minutes, 15 minutes, 30 minutes, 40 minutes, 50 minutes, 60 minutes, and the like. The impregnation times were 5 minutes in both the examples and comparative examples, which are merely comparable.
In the above technical solution, preferably, in step (i), the material of the raw fabric is cotton, acrylic, polyester, polypropylene or spandex, and the raw fabric is in the form of textile, knitwear or non-woven fabric. The raw material fabrics in the embodiment and the comparative example of the invention are all mattress cloth fabrics provided by the company of the division of the like furniture, which are just the same ratio, the double-sided circular knitting machine sandwich jacquard fabric is a composite fabric which is formed by combining a front side, a sandwich and a back side into a whole through joint, and has the following specific specification:
in the above technical solution, the solution carrying rate in the solution carrying fabric a in the step (i) is not particularly limited, and a person skilled in the art can reasonably control the solution carrying rate according to the silver content in the antibacterial finishing solution of the fabric, the capacity of the fabric to adsorb the finishing solution, the silver content of the antibacterial fabric to be obtained, whether the fabric is extruded or not after impregnation and the extrusion degree. The present specification takes the meaning of liquid carrying rate, i.e. the ratio of the raw fabric with the fabric antimicrobial finish, as is usual in the art, based on weight and relative to the raw fabric. By way of example only, the belt rate in the belt fabric a may be 50-100% by weight and relative to the raw fabric, more specific non-limiting examples of belt rates being 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% and so forth. The liquid carrying rate of the liquid carrying fabric a in the examples and comparative examples was 80% by comparison only.
In the above technical solution, the temperature and time of drying in the step (ii) are not particularly limited, as long as a comparable technical effect can be obtained by removing part or all of the water in the liquid-carrying fabric a. However, the person skilled in the art knows that the lower the temperature of drying, the more thoroughly the water needs to be removed, and that the longer the time needed for drying tends to be, and that the person skilled in the art is able to reasonably select the time and temperature for drying according to this principle without having to carry out the inventive task.
In the above-described embodiments, for example, but not limited to, the temperature of the drying in the step (ii) is 80 to 110 ℃, and more specific, non-limiting examples of the temperature of the drying in the step (ii) are 85 ℃, 90 ℃, 95 ℃, 100 ℃, 105 ℃, and the like. The drying temperature in step (ii) in examples and comparative examples was 100℃for the same comparison only.
In the above technical solution, the drying time in the step (ii) is, for example, but not limited to, 3min or more, for example, but not limited to, 4min, 5min, 6min, 7min, 8min, 9min, 10min, 15min, 20min, 25min, 30min, 40min, 50min, 60min, etc. The drying time in step (ii) in examples and comparative examples was 5min, only in the same ratio.
In the above technical solution, the purpose of the baking in step (iii) is to further remove the residual water introduced from the antibacterial finishing liquid of the fabric, and at the same time, the crosslinking agent added in the finishing liquid is crosslinked to fix the silver in the fabric more firmly, so that the baking temperature and baking time can be reasonably selected by a person skilled in the art.
In the above-mentioned embodiments, for example, but not limited to, the baking temperature in the step (iii) is 130 to 180 ℃, and as a more specific non-limiting example, the baking temperature in the step (iii) is 132 ℃, 134 ℃, 136 ℃, 138 ℃, 140 ℃, 142 ℃, 144 ℃, 146 ℃, 147 ℃, 148 ℃, 150 ℃, 152 ℃, 154 ℃, 156 ℃, 158 ℃, 160 ℃, 165 ℃, 170 ℃, 175 ℃, and the like. The baking temperature in step (iii) in examples and comparative examples was 150℃by comparison only.
In the above technical scheme, for example, but not limited to, the baking time in the step (iii) is more than 1 min. As more specific non-limiting examples, the time of baking of step (iii) is 1.5min, 2min, 2.5min, 3min, 3.5min, 4min, 4.5min, 5min, 5.5min, 6min, 6.5min, 7min, 7.5min, 8min, 8.5min, 9min, 9.5min, and the like. The baking time of step (iii) in the examples and comparative examples was 3min, only by the same ratio.
