Method for manufacturing fibre containing bismuth germinate micro-nano powder

Abstract

The invention relates to the filed of fiber manufacture, in particular to a fiber manufacture method of micro-nano powder comprising bismuth germinate. The invention uses polyester, polypropylene or nylon as base material which comprises 1 percent to 50 percent of multielement mixing ultra-fine powder by weight percentage, and the multielement mixing ultra-fine powder comprises the following ingredients by the following weight percentage: 1 percent to 49 percent of bismuth germinate micro powder, 1 percent to 49 percent of tin dioxide, 1 percent to 2 percent of trace elements beneficial to human bodies, such as calcium, kalium, iron, zinc, silver, and the like, and the granularity of the trace elements is from 0.3 micron to 0.5 micron. After being sliced, the base material is stirred with the multielement mixing ultra-fine powder, wherein the weight percentage of the mixed ultra-fine powder in the base material slices is 1 percent to 50 percent, then 1 percent to 5 percent of a polymer spinning aid is added, melted and fully stirred for 20 minutes at a melting temperature of 260 DEG C to 286 DEG C, and the mixture is sprayed, cooled, fixed, curled, pulled to form the fibers comprising the bismuth germinate.

Description

technical field [0001] The invention relates to the field of fiber manufacturing, in particular to a fiber manufacturing method containing bismuth germanate micronano powder. Background technique [0002] With the development of science and technology, various new materials have gradually become a new research direction to meet the needs of human life. The effects of various metals or semiconductor metal elements on the human body have attracted more and more attention. At present, nanotechnology is becoming more and more mature, and functional fibers made by adding metal or semiconductor metal element composite inorganic nanopowders to traditional chemical fibers have been launched one after another. Among them, far-infrared products made by adding far-infrared ceramic powder to chemical fibers have a significant effect of keeping warm and improving the health care function of human microcirculation, which has been verified by inspection and recognized by consumers.

Problems solved by technology

[0003] The patent of CN1027983C discloses that a large amount of zirconia has been used in the fiber. However, due to the large proportion and high hardness of zirconia, the cloth produced by the fiber containing a large amount of zirconia ultrafine powder is compared with the cloth of the same specification produced by ordinary fiber. The unit weight per square decimeter is obviously high, and the softness is poor; in addition, the production technology of high-performance zirconia is difficult, and the international market is basically monopolized by a few developed countries. At present, most of our country relies on imports, resulting in high production costs.

However, in the process of adding pure germanium metal to the fiber, it is difficult to achieve the 0.3-0.5μ ultrafine powder necessary for fiber addition, and it is difficult to achieve the original purpose
