Problems solved by technology

However, nano-powders are extremely fine, easy to agglomerate, and are not easy to disperse into plastics in a high-viscosity state, making it difficult to play an effective role.
At the same time, there is also such a problem: in the existing antibacterial polymer materials, the antibacterial components inside the resin cannot effectively migrate to the surface, and play its role, wasting its function
[0006] However, the bedding prepared by the above invention has insufficient long-term antibacterial performance, and its antibacterial performance is easy to lose

Abstract

The invention relates to bedding prepared from a polyester antibacterial masterbatch based on a one-dimensional nanometer Ag / C composite material, belonging to the technical field of high-tech functional composite materials. According to the invention, polyester resin which is prepared by blending the polyester antibacterial masterbatch in proportion is subjected to conventional pre-crystallization, drying and melt spinning successively to prepare antibacterial polyester fibers, and the antibacterial polyester fibers are woven or are blended and interwoven with cotton, hemp and other chemicalfibers to form an antibacterial fabric. The polyester antibacterial masterbatch is prepared from polyester, a one-dimensional nanometer Ag / C composite material, micro-nano inorganic powder, an auxiliary agent and the like through blending, plasticizing, mixing, extruding, drawing, cooling and granulation. According to the invention, the one-dimensional nanometer Ag / C composite material is fully and effectively dispersed, so the one-dimensional nanometer Ag / C composite material is prevented from failures due to agglomeration and allowed to maintain long-lasting antibacterial effect; and the prepared bedding fabric has the characteristics of broad-spectrum antibacterial performance, high efficiency, durability, washing resistance, excellent performance, safety to the body, no toxicity, no harm, no allergenicity, environment protection performance, etc.

Description

technical field [0001] The invention belongs to the field of high-tech functional composite materials, in particular to a bedding prepared from polyester antibacterial masterbatch based on one-dimensional nano Ag / C composite materials. Background technique [0002] Diseases caused by various pathogenic bacteria, fungi and viruses seriously threaten human health, therefore, various antibacterial materials have become the focus of research. There is also an increasing demand for high molecular polymer materials with antibacterial functions. If it is required to have a permanent antibacterial effect, the preparation method of antibacterial polymer materials can only be added in the form of masterbatches. [0003] Inorganic antibacterial materials have been used more and more important due to their excellent safety, durability, slow release and chemical stability, and convenient use. However, nano-powders are extremely fine, easy to agglomerate, and are not easy to disperse in...
