[0027] Step 1: Prepare Ti-30Cu antibacterial powder,

[0028] Select 500-mesh titanium powder and 600-mesh copper powder, the mass ratio of titanium powder and copper powder is 70:30; weigh the raw material powder according to the ratio, and ball mill the raw material powder on a ball mill to mix evenly. Then it is molded into a green embryo under a pressure of 350Mpa, and the vacuum degree is lower than 1×10 -3 Under the environment of MPa, the prefabricated green body is heated to 800°C for high-temperature sintering, the sintering time is 3h, and the mechanical pressure is 20Mpa. After cooling with the furnace, Ti-30Cu antibacterial powder is obtained, and the copper phase is treated as ε-Cu. Mutually. Then, the Ti-30Cu antibacterial powder is ball-milled on a planetary high-energy ball mill for 48 hours to obtain an ultrafine Ti-30Cu antibacterial powder with a particle size of less than 0.5 μm.

[0034] Step 1: Preparation of Ti-30Cu antibacterial powder

[0035] Weigh 400-mesh titanium powder and 500-mesh copper powder, the mass ratio of titanium powder and copper powder is 70:30, weigh the raw material powder according to this ratio, and ball mill the raw material powder on a ball mill to mix evenly. Then it is molded into a green embryo under a pressure of 450Mpa, and the vacuum degree is lower than 1×10 -3 Under the environment of Mpa, the prefabricated green body is heated to 900°C for high-temperature sintering, the sintering time is 1.5h, and the mechanical pressure is 15Mpa. After cooling with the furnace, Ti-30Cu antibacterial powder is obtained, and the copper phase appears as ε- Cu phase. Then, the Ti-30Cu antibacterial powder was ball-milled on a planetary high-energy ball mill for 46 hours to obtain an ultrafine Ti-30Cu antibacterial powder with a particle size of less than 0.45 μm.

Abstract

The invention discloses a preparation method of copper-containing antibacterial fibre. The preparation method of the copper-containing antibacterial fibre comprises the steps of: (1), preparing Ti-30Cu antibacterial powder and / or Ti-6Al-4V-3Cu antibacterial powder; (2), preparing an antibacterial fibre melt: selecting the Ti-30Cu antibacterial powder, the Ti-6Al-4V-3Cu antibacterial powder or themixture of the Ti-30Cu antibacterial powder and the Ti-6Al-4V-3Cu antibacterial powder, wherein the mass ratio of all antibacterial powder to a fibre-forming high polyethylene terephthalate section is(10-20):(80-90); and uniformly mixing all the antibacterial powder and the fibre-forming high polyethylene terephthalate section at 230-280 DEG C, so that the antibacterial fibre melt is obtained; and (3), heating the antibacterial fibre melt, and preparing the antibacterial fibre through a blended spinning method. The preparation method in the invention is low in production cost and good in antibacterial property.

Description

technical field [0001] The invention belongs to the technical field of antibacterial fiber preparation and relates to a preparation method of copper-containing antibacterial fiber. Background technique [0002] In recent years, with the development of the economy and the improvement of living standards, consumers' pursuit of textile fabrics is not limited to aesthetics and wearing comfort, but also puts forward higher requirements for the health care function of fabrics. Therefore, the textiles with antibacterial and deodorizing that arise at the historic moment have been favored by domestic and foreign consumers. Fiber is the basic unit of textiles, which determines the functional properties of textiles. Antibacterial fiber has the functions of sterilizing and deodorizing, inhibiting the reproduction of microorganisms, blocking the spread of diseases, cleaning and maintaining the performance of fibers themselves, preventing textiles from being damaged by microbial erosion,...
