Abstract
A method of making a bacteria indicating fabric, a bacteria indicating fabric and a garment are disclosed. In the preparation method of the bacteria indicating fabric, the bacteria indicating microcapsule is prepared and coated on the base fabric to prepare the bacteria indicating fabric. The bacteria indicating fabric and the clothes thereof can achieve the purpose of reminding a user when the fabric needs to be washed.
Description
Technical Field
The invention relates to the field of fabrics, in particular to a preparation method of a bacteria indicating fabric, the bacteria indicating fabric and clothes.
Background
In recent years, with the continuous development of textile industry technology and the continuous improvement of living standard of people, people prefer a healthy living style, the participation and investment in sports are more and more, and the requirements on sports clothes are not only limited to styles, colors and the like, but also put higher requirements on comfort, functionality and safety.
In life, human beings live with bacteria every day, and when the immune system of the human body is normal, ecological balance is formed. However, on the textile close to the human body, because of the porosity of the textile material and the chemical structure formed by the high molecular polymer, the textile material becomes a good carrier suitable for the existence of microorganisms, sebum secreted by the human body and the like provide abundant nutrition for the microorganisms, and if the normal flora is not well inhibited, the ecological imbalance of bacterial colonies can be caused, the growth of bacteria is aggravated, various diseases can be caused, and the health of the human body is harmed. It is known that cleaning fabrics by washing removes most of the bacteria on the fabric; there is therefore a need for a functional textile that will indicate to the consumer when the fabric needs to be washed for the purpose of removing bacteria.
Disclosure of Invention
The invention aims to overcome the defects or problems in the prior art and provides a preparation method of a bacteria indicating fabric, the bacteria indicating fabric and clothes, so as to achieve the purpose of reminding a user when the fabric needs to be washed.
In order to achieve the purpose, the following technical scheme is adopted:
a preparation method of a bacteria indicating fabric comprises the following steps: s1: the first composition is prepared by mixing the following components in percentage by weight: a first component: 30-40% of methylene blue; a second component: phenol red, eosin or neutral red 30-40%; and a third component: 30-40% of p-nitrophenyl-beta-D-glucopyranoside or o-nitrophenol beta-D glucuronide; s2: preparing a beta-cyclodextrin water solution with the mass percent of 35-45%; s3: adding a first composition into a beta-cyclodextrin aqueous solution, stirring and emulsifying, wherein the weight percentage of the first composition is 50-70%; s4: spraying into liquid drops; s5: drying with 150-; s6: the coating is prepared by adding the following components into water: 0.5-10g/L of bacteria indicating microcapsule, 5-20g/L of thickening agent, 2-5g/L of cross-linking agent and 1-3g/L of accelerating agent; s7: and coating the coating on the fabric base cloth by a printing or coating process to obtain the bacteria indicating fabric.
A bacteria indicating fabric is prepared by the preparation method of the bacteria indicating fabric.
A garment is provided, wherein at least part of the fabric is the fabric.
Compared with the prior art, the scheme has the following beneficial effects:
the coated substance in the bacterial indicator microcapsule comprises one of p-nitrophenyl-beta-D-glucopyranoside and o-nitrophenol beta-D glucuronide, and can react with bacterial metabolites. When the resultant after the reaction is acidic, it may be indicated by methylene blue, and when the resultant after the reaction is basic, it may be indicated by one of phenol red, eosin, or neutral red. Therefore, the fabric can achieve the purpose of reminding a user when the fabric needs to be washed.
The beta-cyclodextrin is used as a coating material, so that the slow release effect can be achieved, and the repeated use frequency of the bacterial indication function is improved.
Detailed Description
In the claims and specification, unless otherwise defined, the terms "comprising", "having" and variations thereof mean "including but not limited to".
The first embodiment is as follows:
s1: preparing a first composition according to the ratio of the first component to the second component to the third component of 1:1: 1; wherein the first component is methylene blue; the second component is phenol red; the third component is p-nitrophenyl-beta-D-glucopyranoside;
s2: preparing a beta-cyclodextrin water solution with the mass percent of 40%;
s3: adding a first composition into a beta-cyclodextrin aqueous solution, stirring and emulsifying, wherein the weight percentage of the first composition is 60%;
s4: spraying into liquid drops;
s5: drying with 150-;
s6: the coating is prepared by adding the following components into water: 5g/L of bacteria indicating microcapsule, 15g/L of thickening agent, 4g/L of cross-linking agent and 2g/L of accelerating agent;
s7: the coating is coated on white single-sided single-face cloth (component fabric is prepared by using printing process.
Using dropper to take 1ml of bacterial liquid (the concentration of strain is 4X 10) at room temperature8CFU/ml) was dropped on the fabric sample, and after 1 minute the surface color of the sample was observed and recorded as follows:
| numbering | Bacterial strain | Strain numbering | Color of fabric sample |
| 1 | Staphylococcus aureus | AATCC25923 | Pink colour |
| 2 | Escherichia coli | AATCC25922 | Blue green color |
It can be seen that the fabric of this embodiment is indicative of bacteria.
Clothes made of the fabric can be repeatedly washed with water for 20 times and still have a bacteria indicating function.
Example two:
s1: preparing a first composition according to the ratio of the first component to the second component to the third component of 1:1: 1; wherein the first component is methylene blue; the second component is eosin; the third component is o-nitrophenol beta-D glucuronide;
s2: preparing a beta-cyclodextrin water solution with the mass percent of 40%;
s3: adding a first composition into a beta-cyclodextrin aqueous solution, stirring and emulsifying, wherein the weight percentage of the first composition is 70%;
s4: spraying into liquid drops;
s5: drying with 150-;
s6: the coating is prepared by adding the following components into water: 6g/L of bacteria indicating microcapsule, 17g/L of thickening agent, 3g/L of cross-linking agent and 3g/L of accelerating agent;
s7: the coating is coated on white double-sided peak nest cloth (the component is 100 percent of terylene) by a printing process to prepare the bacteria indicating fabric.
Using dropper to take 1ml of bacterial liquid (the concentration of strain is 4X 10) at room temperature8CFU/ml) was dropped on the fabric sample, and after 1 minute the surface color of the sample was observed and recorded as follows:
| numbering | Bacterial strain | Strain numbering | Color of fabric sample |
| 3 | Staphylococcus aureus | AATCC25923 | Pink colour |
| 4 | Escherichia coli | AATCC25922 | Blue green color |
It can be seen that the fabric of this embodiment is indicative of bacteria.
Clothes made of the fabric can be repeatedly washed with water for 20 times and still have a bacteria indicating function.
Except for the two embodiments, the same effect can be achieved by adopting neutral red as the second component and nylon, polypropylene or acrylic as the yarn body to manufacture the bacteria indicating yarn.
The description of the above specification and examples is intended to be illustrative of the scope of the present invention and is not intended to be limiting.
