Abstract
The invention relates to a surface treatment method of a high-strength fabric for a children tent, and belongs to the technical field of surface treatment of fabrics. The surface treatment method of the invention utilizes bismuth vanadate to dope titanium dioxide sol, so that the doped sol is directly prepared on polyester fiber fabric, the antibacterial performance is better, and meanwhile, after the treatment of the modified silane coupling agent, the modified silane coupling agent is not easy to peel off, the strength of the fiber fabric is not affected, and after the water washing and friction test, the higher antibacterial activity is still maintained.
Description
Technical Field
The invention belongs to the technical field of fabric surface treatment, and particularly relates to a surface treatment method of a high-strength fabric for a children tent.
Background
The fabric for manufacturing the tent in the market mainly comprises silk woven by polyester (polyester fiber) yarns, and for children, because the outdoor environment is complex, a plurality of bacteria and microorganisms are arranged, and the body is easy to be injured, nano titanium dioxide is often added to ensure that the tent has antibacterial property when the tent suitable for the children is manufactured.
In the prior art, the antibacterial property of the polyester fiber is mainly realized by a mode of blending spinning and coating. The blended yarn is prepared by directly adding nano titanium dioxide into fiber slices in the form of an additive for melt spinning, and the fiber obtained by the method has good antibacterial property, but the additive has poor miscibility with polyester, so that the strength of the fiber fabric is often influenced. The coating mode is simple to operate and high in production efficiency, but the method can enable the combination of the nano titanium dioxide and the polyester fiber to be unstable and easy to peel, meanwhile, in daily life, the tent needs to be cleaned frequently, the tent needs to be folded every time when being used, and a large amount of friction exists, so that the antibacterial performance of the tent is not durable. In addition, when the nano titanium dioxide is used as a photocatalyst, the available solar energy is only about 4 percent, the particle size of the nano titanium dioxide is small, the nano titanium dioxide has a tendency of spontaneous agglomeration, the nano titanium dioxide is easy to agglomerate, and the inherent properties limit the antibacterial capability of the nano titanium dioxide to a great extent.
Therefore, there are still many places where the production of children tents with antibacterial activity using nano titanium dioxide and polyester fiber is needed to be improved, and it is urgent to provide a new surface treatment method.
