Tablecloth of polyester antibacterial master batch based on nano Cu/C composite material

Abstract

The invention relates to a tablecloth of a polyester antibacterial master batch based on a nano Cu / C composite material, and belongs to the field of high-tech functional composite materials. The tablecloth is prepared by the following steps: mixing a polyester antibacterial master batch and polyester resin according to a ratio, performing conventional pre-crystallization, performing drying, performing melt spinning to prepare antibacterial polyester fibers, and performing re-weaving, or performing blending with cotton, hemp and other chemical fibers to be interwoven into an antibacterial fabric; and performing printing and dyeing finishing on the antibacterial fabric to prepare the tablecloth having an antibacterial function. The method applied in the invention can make the nano Cu / C composite material fully and effectively dispersed, prevent the Cu / C composite material from losing effects due to ''agglomeration'', maintain durability of the antibacterial effect, and enable the nano Cu / C composite material to be effectively used in the polyester resin; and the tablecloth provided by the invention has the characteristics of being broad-spectrum antibacterial, high-efficiency, long-lasting, washing resistant, non-toxic and harmless to the human body, environmentally friendly and the like.

Description

technical field

[0001] The invention belongs to the field of high-tech functional composite materials, in particular to a tablecloth based on polyester antibacterial masterbatch of nanometer Cu / C composite material. Background technique

[0002] Tablecloth is an item that is covered on the table or tabletop to prevent dirt or increase the appearance. Because it is customary to cover the table, it is also called a tablecloth. Due to the usage habits at home and abroad and the specifications of the table, the shapes and names are different. There are square table sets, round table sets, tea table sets, dining table sets, etc. They are mainly used for furnishings, banquets, and meals. They are generally suitable for hotels, teahouses, etc. Sophisticated place.

[0003] The use properties of tablecloths, under moisture, nutrition and suitable temperature, make it very easy to cause the growth and reproduction of microorganisms. Therefore, its antibacterial treatment cannot be...
