Description

Silver ion modified fiber-containing blended antibacterial fabric
Technical Field
The invention relates to an antibacterial fabric, in particular to a blended antibacterial fabric containing silver ion modified fibers.
Background
With the improvement of the quality of life, more and more people are aware of the importance of health, so the requirements of people on clothes are higher and higher, for example, the clothes have an antibacterial effect, while the common fabric is a single-layer fabric, has a single function and does not have antibacterial energy.
The antibacterial fabric has good safety, can prevent bacteria from regenerating and propagating and keep the fabric clean, is a special functional fabric, and is a fabric which can inhibit bacteria and fungi from growing and propagating or lose activity on the fabric after antibacterial finishing or containing antibacterial fibers. The qualified antibacterial fabric has good antibacterial effect and can avoid the propagation of bacteria to a certain extent so as to reduce the risk of being corroded and damaged by harmful microorganisms. Moreover, the fabric can eliminate peculiar smell generated by bacteria, so that the fabric can keep clean and dry for a long time, and the demand of the antibacterial fabric is increasing.
Disclosure of Invention
The invention aims to solve the technical problem that the defects of the prior art are overcome, and the blended antibacterial fabric containing the silver ion modified fibers is provided, and has the advantages of lasting antibacterial effect, good mechanical property, good comfort and certain ultraviolet resistance.
The technical scheme for solving the technical problems is as follows:
the blended antibacterial fabric containing the silver ion modified fibers comprises the following components in parts by mass: silver ion-modified polyester fiber: 10-20%, fabric composite: 10-13%, delinted: 15-20%, the balance being conventional fiber, the sum of the above components being 100%, wherein:
the conventional fiber is silk, bamboo fiber, modal fiber, milk protein fiber and superfine denier modal;
the antibacterial fabric is formed by compounding a first textile layer, a second textile layer, a third textile layer and a fourth textile layer, wherein the first textile layer is a textile composite material layer, the second textile layer is a delinted layer, the third textile layer is a silver ion modified polyester fiber layer, and the fourth textile layer is formed by blending conventional fibers.
The invention further defines the technical scheme as follows:
in the blended antibacterial fabric containing the silver ion modified fibers, the linear density of the silver ion modified polyester fibers is 3.8-4.0dtex, and the breaking strength is 4.7-4.9cN dtex -1 And the moisture regain is 4.3-4.5%.
In the blended antibacterial fabric containing the silver ion modified fiber, the linear density of the delrin is 0.9-1.0dtex, and the breaking strength is 1.37-1.42cN dtex -1 The moisture regain is 2.05-2.10%.
In the blended antibacterial fabric containing the silver ion modified fiber, the conventional fiber comprises the following raw materials in parts by mass: real silk: 10-15 parts of bamboo fiber: 10-13 parts of modal fiber: 15-20 parts of milk protein fiber: 10-12 parts, superfine denier wood daier: 8-11 parts.
In the blended antibacterial fabric containing the silver ion modified fibers, the preparation method of the fabric composite material comprises the following steps:
(1) Fabric pretreatment
Placing the cotton fabric into sodium dodecyl sulfate aqueous solution before use, performing ultrasonic treatment for 1h, washing with deionized water, performing ultrasonic treatment for 30min with absolute ethyl alcohol, washing with deionized water, drying in an oven at 80 ℃ for 1h to obtain a blank cotton fabric, and placing the blank cotton fabric into a plastic sealing bag for later use;
(2) Sol liquid preparation
Dissolving thiourea and urea into absolute ethyl alcohol, adding butyl titanate, adjusting the pH value to 3-4 by using 6wt% of dilute nitric acid, uniformly stirring, slowly dripping deionized water into the solution, continuously stirring for 20-23min, and standing for 0.8-1h to obtain wet gel;
(3) Loaded to produce a textile composite material
And (3) continuously stirring the sol solution obtained in the step (2), after the Tyndall phenomenon occurs, soaking the cotton fabric prepared in the step (1) in the sol solution for 5-7min, taking out the cotton fabric, putting the cotton fabric on a clean glass plate, pressing the cotton fabric on the same glass plate, applying 1kg of weight on the plate, taking out the cotton fabric after 1-3min, and drying the cotton fabric on a glass dish to obtain the fabric composite material.
The technical effect is that the photocatalysis antibacterial mechanism of cotton fabric loaded with doped Ti O2 is as follows: an S-N-TiO2 photocatalytic material loaded on the cotton fabric is mixed with the bacterial suspension for oscillation, and electrons e-with negative electricity are released under certain external conditions (heat, light and the like) while positive holes h + are generated; secondly, abundant cavities act in the environment of water and air, and a highly active and strong oxidizing ability of peroxy ion free radical (. O2-) and hydroxyl free radical (. HO) is generated; these active free radicals can interact with phospholipid molecules and membrane proteins on the cell membrane, thereby deteriorating the fluidity of the membrane.
