Nano-titanium nitride PEN fiber and preparation method thereof

Abstract

The present invention relates to a nano-titanium nitride PEN fiber and preparation method thereof. The raw material comprises the following components, by mass, 1%-10% of antibacterial masterbatch chips and 90%-99% of PEN chips. The preparation method comprises mixing the antibacterial masterbatch chips with the PEN chips uniformly and performing the melt spinning process to obtain the product. The preparation method is characterized in that the spinning temperature is 260 DEG C - 320 DEG C; the air cooling temperature is 15 DEG C - 25 DEG C; the wind speed is 0.1 m / s - 5 m / s; and the drafting speed is 1500 m / min - 2000 m / min. The nano-titanium nitride PEN fiber of the invention has good antibacterial effect and high safety to human and environment, and can be widely applied.

Description

【Technical Field】 [0001] The invention relates to the technical field of PEN fibers, in particular to a nano titanium nitride PEN (polytrimethylene terephthalate) fiber and a preparation method thereof. 【Background technique】 [0002] Bamboo is an important forest resource in our country. It grows fast, can become a material in a short time, has strong regeneration ability, a successful afforestation, and sustainable felling and utilization. In the past, bamboo was mainly used to make farm tools, fuels, furniture, daily necessities, handicrafts, building materials, flooring, and papermaking, with low utilization value. [0003] With the development of science and technology, the domestic use of bamboo to make bamboo charcoal has greatly expanded its application fields. Because titanium nitride has a special structure, its molecular structure is hexagonal, with dense carbon, large specific gravity, many pores, and rich mineral content. It contains potassium, magnesium, iron, mangan...
