Description

Antibacterial artificial fabric
Technical Field
The invention belongs to the field of textiles, and particularly relates to an antibacterial artificial fabric.
Background
Artificial fur refers to a long-pile type fabric that looks like animal fur. The fluff is divided into two layers, the outer layer is bright and thick bristles, and the inner layer is fine and soft short fluff. It is commonly used in coats, garment liners, hats, collars, toys, mattresses, upholstery, carpets, and the like. However, the conventional artificial fur has problems that the antibacterial property is poor, and the existence of the hair layer and the hair surface of the fluff layer easily forms a humid environment, which causes the growth of bacteria.
Therefore, most of the conventional artificial furs have a defect of poor antibacterial property, and improvement of antibacterial performance is demanded.
In this regard, for example, CN203046339U discloses a technical solution of an anti-mite artificial fur, which can achieve the technical effect of anti-mite to some extent by means of an anti-mite agent. However, in the course of long-term use, the mite-proofing agent gradually runs off and loses efficacy due to factors such as washing or oxidation, and the mite-proofing effect thereof is continuously weakened, so that the actual mite-proofing performance retention thereof is poor. The existing antibacterial fur has the problems of poor antibacterial property, difficult stability maintenance after the antibacterial property is improved by modification, and the like.
Disclosure of Invention
The invention provides an antibacterial artificial fabric, aiming at solving the problems that the existing artificial fur has poor antibacterial performance or the antibacterial performance is difficult to maintain for a long time and the like.
The invention aims to:
firstly, the antibacterial performance of the artificial fur is improved;
and secondly, the antibacterial performance of the artificial fur is ensured to be maintained for a long time.
In order to achieve the purpose, the invention adopts the following technical scheme.
An antibacterial artificial fabric is composed of a fabric body,
comprises a wool surface and a base fabric;
the base fabric consists of a core layer, a transition layer, an antibacterial layer and a surface layer;
the core layer is in a roving weaving structure, and the transition layers are sewn on the front surface and the back surface of the core layer and are compact weaving layers;
the antibacterial layer is arranged on the outer surface of the transition layer, the surface layer is a short fluff fiber layer, the surface layer is fixedly sewn with the transition layer and realizes fixation to the antibacterial layer, and the antibacterial layer is loaded with an antibacterial agent.
The concrete structure is shown in fig. 1, and is composed of a hair side 100 and a base fabric 200. The specific structure of the base fabric is shown in fig. 2, which is a core layer 201, a transition layer 202, an antibacterial layer 203 and a surface layer 204 from inside to outside, and is symmetrically arranged with the core layer as the center, for example, the transition layer 202 forms an upper transition layer 202a and a lower transition layer 202b on the upper and lower surfaces of the core layer, the antibacterial layer forms an upper antibacterial layer 203a and a lower antibacterial layer 203b, and the surface layer forms an upper surface layer 204a and a lower surface layer 204b, and the upper surface layer is connected with the matte surface. The core layer is used as a middle core layer and mainly determines the properties of the base fabric such as flexibility and the like, the transition layer plays a certain transition separation role, the antibacterial layer realizes a primary antibacterial effect, and the surface layer ensures the properties of the base fabric such as wear resistance and the like and protects the base fabric. The whole base fabric is arranged in a symmetrical structure, so that the fixing and maintaining effects on the catalyst can be improved. The reason for this is based on the selection of the fibers of each layer as described below.
As a preference, the first and second liquid crystal compositions are,
the core layer is made of 26-40 dtex polyester fiber and 7-12 dtex cotton fiber in a mass ratio of 1: (0.2-0.25) by blending;
the transition layer is woven by using 2.5-3 dtex medium-long fibers;
the antibacterial layer is a refined dry cotton layer made of ramie fibers with the length of 50-70 mm and the dtex of 0.7-0.9;
the surface layer is formed by weaving 4.5-5.5 dtex short fluff fiber.
The core layer is formed by mixing thicker polyester fibers and thinner cotton fibers, the core layer has a rich pore structure and has good flexibility and elasticity, the transition layer is woven by using thinner medium-long fibers, the formed transition layer can not only realize the separation of the antibacterial layer and the core layer, protect the core layer which is not wear-resistant and is easy to damage, but also can play a role of 'buffer' of antibacterial agents in the fabric washing process, the finest antibacterial layer carries the antibacterial agents, the antibacterial agents are easy to lose along with the stirring of water flow and the like in the washing process, but are easy to be absorbed into the transition layer firstly and buffered in the transition layer under the cooperation of the transition layer, the loss of the antibacterial agents can be effectively reduced, the retention rate of the antibacterial agents is improved, and the water gradually loses in the airing and drying processes, the immobilization of the antibacterial agent is again formed by the capillary action of the antibacterial layer to achieve efficient retention of the antibacterial agent. The surface layer of the outermost layer is woven by using thicker short fluffy fibers, so that the surface layer can generate skin-friendly and soft texture, has good mechanical properties such as wear resistance and the like, and forms an antibacterial agent which is guided by water flow in the washing process and is in an antibacterial layer and can easily enter the transition layer due to the larger weaving aperture.
As a matter of preference,
the wool surface is made of 17-34 dtex profiled fibers.
The special-shaped fibers selected comprise a kidney shape, a dumbbell shape, a polygonal shape and the like, are bright, thick and straight and have a rough and rough surface, and form fur texture.
As a matter of preference,
the antibacterial agent includes:
15-25 parts of methyl chlorisonazole ketone, 10-20 parts of epichlorohydrin, 40-45 parts of lauryl carboxymethyl sodium imidazoline acetate, 0.1-0.2 part of ethylenediamine sodium iron bis (o-hydroxyphenyl) diacetate and 2-4 parts of decabiguanide dihydrochloride.
The antibacterial agent with the proportion can realize good antibacterial and bacteriostatic effects and is favorable for combination with the fabric layer.
As a matter of preference,
the loading process of the antibacterial agent is as follows:
and dissolving the materials in water according to a ratio to prepare a dipping solution of 40-60 g/L, and treating the antibacterial layer by using a padding process.
By adopting the loading process, the loading of the antibacterial agent can be efficiently realized.
As a preference, the first and second liquid crystal compositions are,
the rolling allowance rate of the padding process is 60-75%;
the padding process is repeated for 2-4 times, and drying treatment is carried out at the temperature of 60-70 ℃ after each padding process is finished.
The loading capacity of the antibacterial agent can be effectively improved by carrying out the padding operation for a plurality of times with lower rolling residual rate. Particularly for the control of the rolling residual rate, if the rolling residual rate is too low, the antibacterial agent can be diffused along with the water loss, and if the rolling residual rate is too high, the aperture of the antibacterial layer is easily damaged and enlarged by the mechanics, so that the actual loading capacity of the antibacterial agent in the antibacterial layer and the retention of the antibacterial agent are easily influenced.
As a preference, the first and second liquid crystal compositions are,
the core layer is also blended with modified antibacterial fiber.
The modified antibacterial fiber is blended in the core layer, so that the antibacterial performance of the whole fabric can be effectively improved, and the antibacterial fiber is less prone to loss compared with an antibacterial agent, so that the fabric can keep a few antibacterial properties.
As a preference, the first and second liquid crystal compositions are,
the modified antibacterial fiber is a titanium-manganese alloy fiber;
the wire diameter of the titanium-manganese alloy fiber is 80-100 mu m.
The titanium manganese alloy fiber is placed in 0.5mol/L KMnO4 sodium silicate water solution to obtain electrolyte with specific gravity of 1.0, and the solution is subjected to 0.02A/dm 2 The micro-arc oxidation is carried out to form a rough titanium-manganese oxide composite shell layer, the antibacterial performance of the titanium-manganese alloy fiber can be further improved on the surface of the titanium-manganese alloy fiber with a certain antibacterial property, and the formed titanium-manganese oxide composite shell layer can be released slowly in a long-acting manner in a liquid phase system, so that the antibacterial and sterilization effects are realized, and the long-acting antibacterial and sterilization effects are maintained. As a preference, the first and second liquid crystal compositions are,
injecting zinc ions and copper ions into the titanium-manganese alloy fiber by an ion injection method;
the injection amount of the zinc ions is 2-4 wt% of the total mass of the titanium-manganese alloy fiber;
the injection amount of the copper ions is 4-7 wt% of the total mass of the titanium manganese alloy fiber.
After the zinc ions and the copper ions are implanted by an ion implantation method, the zinc ions and the copper ions can be matched with the long-acting slow release of the titanium manganese oxide composite shell layer to realize slow release antibiosis, so that the fabric in washing and wet states can keep higher antibiosis performance.
The invention has the beneficial effects that:
1) the antibacterial effect of the fabric is realized through an antibacterial agent;
2) through the matching of the structures of the base fabric layers, the loss of the antibacterial agent in the actual use and washing process is reduced, and the antibacterial performance retention rate is improved;
3) by adding and using the modified antibacterial fiber, the antibacterial property and antibacterial property retention rate of the fabric are further improved.

Comparative example 1
The procedure is as in example 1, except that:
the antibacterial layer is woven by 2.5dtex medium-long fibers.
Comparative example 2
The procedure is as in example 1, except that:
the surface layer is woven by 1.8dtex short fluff fiber.
Test I
The antibacterial performance tests of examples 1 to 6 and comparative examples 1 to 2 have been conducted to test the antibacterial performance maintaining effect.
The antibacterial performance test is carried out according to the GB/T20944.2-2007 national standard second part absorption method. The antibacterial performance retention effect test is based on the fact that the fabric is placed in a common blue moon detergent (according to the standard dosage of the fabric) to be repeatedly washed and aired for 10 times and then tested again, and the test result is compared with the initial test result of the national standard.
The test results are shown in table 1 below.
Table 1: results of the antibacterial property and antibacterial property-maintaining effect test
Test group Antibacterial ratio (%) Antibacterial Retention ratio (%) Test group Antibacterial ratio (%) Antibacterial Retention ratio (%)
Example 1 ＞99 95.05 Example 5 ＞99 95.80
Example 2 ＞99 95.83 Example 6 ＞99 95.92
Example 3 ＞99 95.00 Comparative example 1 ＞99 77.11
Example 4 ＞99 95.67 Comparative example 2 ＞99 84.61
As can be seen from the above test results, the influence of the layer structure on the initial antibacterial retention is not significant, and the initial antibacterial retention is mainly determined by the action of the antibacterial agent. However, the structure of the base fabric layer has a great influence on the antibacterial retention rate, and in comparative example 1, the antibacterial retention rate is very significantly reduced after the antibacterial layer is woven with the coarse fibers. The reason is that the antibacterial agent is difficult to realize stable loading in the antibacterial layer and is easy to run off, and the comparative example 2 adopts thinner short fluff fiber to prepare, so that the flow guide effect cannot be formed, the transition layer cannot be used as a good catalyst buffer transition area, and the catalyst is easy to run off from a thinner surface layer instead in the washing process.

the formula of the antibacterial agent is as follows:
15 parts of methyl chlorisonazole ketone, 20 parts of epichlorohydrin, 40 parts of lauryl carboxymethyl sodium type imidazoline acetate, 0.2 part of ethylenediamine sodium iron bis-o-hydroxyphenyl diacetate and 2 parts of decabiguanide dihydrochloride;
in this example, the loading manner of the antibacterial agent is as follows:
dissolving the antibacterial agent components in water to prepare 60g/L of impregnation liquid, and treating the antibacterial layer by using a padding process, wherein the rolling residual rate of the padding process is controlled to be 75%;

in this example, the loading manner of the antibacterial agent is as follows:

the formula of the antibacterial agent is as follows:
15 parts of methyl chlorisonazole ketone, 20 parts of epichlorohydrin, 40 parts of lauryl carboxymethyl sodium type imidazoline acetate, 0.1 part of ethylenediamine sodium iron bis-o-hydroxyphenyl macroacetate and 4 parts of decabiguanide dihydrochloride;
in this example, the loading manner of the antibacterial agent is as follows:

in this example, the loading manner of the antibacterial agent is as follows:
dissolving the antibacterial agent components in water to prepare 40g/L of impregnation liquid, treating the antibacterial layer by using a padding process, and controlling the rolling allowance rate of the padding process to be 60%;
the padding process is repeated for 2 times, and drying treatment is carried out at the temperature of 60 ℃ after each padding process is finished.

The procedure is as in example 1, except that:
the rolling residual rate is controlled to be 45 percent.
Comparative example 5

the padding process is performed only once.
Test II
The same tests as those of test I were carried out for examples 7 to 10 and comparative examples 3 to 5 described above. The test results are shown in table 2 below.
Table 2: test results of test II
Test group Antibacterial ratio (%) Antibacterial Retention ratio (%) Test group Antibacterial ratio (%) Antibacterial Retention ratio (%)
Example 7 ＞99 95.43 Comparative example 3 ＞99 87.22
Example 8 ＞99 95.89 Comparative example 4 98.91 95.02
Example 9 ＞99 95.56 Comparative example 5 98.42 95.80
Example 10 ＞99 95.12
From the result of the test II, it can be seen that the process parameters of the padding process have a certain influence on the antibacterial rate and antibacterial retention rate of the fabric. But the catalyst is adjusted within a reasonable parameter range, and the influence on the antibacterial rate is basically negligible. In the case where the rolling residue rate was excessively high, the pore structure of the antibiotic layer was crushed and deformed to some extent, and thus antibiotic retention rate of comparative example 3 was very significantly decreased. In the case where the mangle ratio is excessively low, the initial antibacterial ratio is lowered, but the antibacterial retention rate can be substantially maintained. When the padding treatment is performed only once, the antibacterial retention rate is kept excellent, but the antibacterial rate is also reduced to a certain extent.
The above tests and test results are essentially in line with expectations.
Example 11
The procedure is as in example 1, except that:
modified antibacterial fibers are blended in the core layer, and the addition amount of the modified antibacterial fibers is 6 wt% of the total mass of the polyester fibers and the cotton fibers;
the modified antibacterial fiber is a titanium-manganese alloy fiber;
the wire diameter of the titanium-manganese alloy fiber is 80 μm.
The titanium manganese alloy fiber is placed in a sodium silicate aqueous solution with the proportion of 0.5mol/L and KMnO is added into the sodium silicate aqueous solution with the proportion of 10g/L 4 The specific gravity of the obtained electrolyte was 1.0, and the solution was subjected to a treatment of 0.02A/dm 2 Micro-arc oxidation for 20min to form coarse titanium manganese oxide composite shellThe layer can further improve the antibacterial performance of the titanium-manganese alloy fiber on the surface of the titanium-manganese alloy fiber with certain antibacterial property, and the formed titanium-manganese oxide composite shell layer can be released slowly in a long-acting manner in a liquid phase system, so that the antibacterial and bactericidal effects are realized, and the long-acting antibacterial and bactericidal effect is maintained.
Example 12
The procedure is as in example 1, except that:
modified antibacterial fibers are blended in the core layer, and the addition amount of the modified antibacterial fibers is 8 wt% of the total mass of the polyester fibers and the cotton fibers;
the modified antibacterial fiber is a titanium-manganese alloy fiber;
the wire diameter of the titanium-manganese alloy fiber is 100 mu m.
The titanium manganese alloy fiber is placed in a sodium silicate aqueous solution with the proportion of 0.5mol/L and KMnO is added into the sodium silicate aqueous solution with the proportion of 10g/L 4 The specific gravity of the obtained electrolyte was 1.0, and the solution was subjected to a treatment of 0.02A/dm 2 And performing micro-arc oxidation for 20min to form a coarse titanium-manganese oxide composite shell layer, so that the antibacterial performance of the titanium-manganese oxide composite shell layer can be further improved on the surface of the titanium-manganese alloy fiber with a certain antibacterial property, and the formed titanium-manganese oxide composite shell layer can be released slowly in a long-acting manner in a liquid phase system, so that the antibacterial and sterilization effects are realized, and the long-acting antibacterial and sterilization effects are maintained.
Example 13
The procedure is as in example 11, except that:
injecting zinc ions and copper ions into the titanium-manganese alloy fiber by an ion injection method;
the injection amount of the zinc ions is 2 wt% of the total mass of the titanium-manganese alloy fiber;
the injection amount of the copper ions is 7 wt% of the total mass of the titanium-manganese alloy fiber.
Example 14
The procedure is as in example 11, except that:
injecting zinc ions and copper ions into the titanium-manganese alloy fiber by an ion injection method;
the injection amount of the zinc ions is 4 wt% of the total mass of the titanium-manganese alloy fiber;
the injection amount of the copper ions is 4 wt% of the total mass of the titanium-manganese alloy fiber.
Test III
The same test I was conducted for the above examples 11 to 14, and the test results are shown in Table 3 below.
Table 3: test III test results
Test group Antibacterial ratio (%) Antibacterial Retention ratio (%) Test group Antibacterial ratio (%) Antibacterial Retention ratio (%)
Example 11 ＞99 97.42 Example 13 ＞99 ＞99
Example 12 ＞99 96.98 Example 14 ＞99 ＞99
From the test results shown in table 3, the overall antibacterial retention rate of the fabric is obviously improved after the modified antibacterial fiber is added. Particularly, after the modified antibacterial fiber is injected with zinc ions and copper ions by an ion injection method, the antibacterial retention rate of the fabric can be more effectively improved, mainly because the modified antibacterial fiber is less prone to loss compared with an antibacterial agent, after the ion injection, the active ion amount of the modified antibacterial fiber can be further improved, and in the using process, the antibacterial effect can achieve a longer retention effect.
The antibacterial retention rate test for example 13 and example 14 was conducted for a longer period of time, and the test results are shown in table 4 below.
Table 4: test results of antibacterial retention ratio for a long time
Figure GDA0003675338320000131
As can be seen from the above test results, in the case where the ion implantation amount is substantially equivalent, the antibacterial performance maintaining effect by implanting copper ions is weaker than that by zinc ions, and thus the antibacterial performance maintaining effect by zinc ion implantation is more effective in practice. In conclusion, the novel antibacterial artificial fabric has a better antibacterial effect and a very excellent antibacterial performance maintaining effect through the matching of the structure and the material components, and can still maintain the better antibacterial performance after being used for a long time.
