Making methods of Lycra fiber capable of inducing generation of negative oxygen ions, negative oxygen ion functional powder and negative oxygen ion functional auxiliary agent

Abstract

The invention discloses making methods of a Lycra fiber capable of inducing the generation of negative oxygen ions, negative oxygen ion functional powder and a negative oxygen ion functional auxiliaryagent. The making method of the negative oxygen ion functional powder comprises the following steps that ion-adsorbing rare earth ore, magnesium-enriched fibrous silicate and hydrous magnesium silicate are baked and dried; the baked and dried magnesium-enriched fibrous silicate and ion-adsorbing rare earth ore are extracted by utilizing an acidic extractant, and high-temperature baking is performed after extraction to remove radioactive elements; amorphous silica is heated to reduce the content of soluble silicic acid in the silica; the hydrous magnesium silicate, the magnesium-enriched fibrous silicate, the ion-adsorbing rare earth ore and the silica are crushed and mixed uniformly to obtain the negative oxygen ion functional powder. By means of the making methods, the raw material costof the negative oxygen ion functional powder is low, the produced Lycra fiber for the negative oxygen ions can continuously induce the generation of the negative oxygen ions into the space through ionization, the generation inducing quantity is 1,200-2,500 per cubic meter, the living space of people can be improved, and the air and environment are purified.

Description

technical field [0001] The invention relates to the technical field of functional fabrics, in particular to a production method of a Lycra fiber that induces negative oxygen ions and a functional auxiliary for negative oxygen ions. Background technique [0002] Lycra fiber, also known as spandex, is the abbreviation of polyurethane fiber. It is a kind of elastic fiber. It is highly elastic and can be stretched 6 to 7 times, but it can quickly return to its original state as the tension disappears. Latex silk is 2 to 3 times higher, the linear density is finer, and it is more chemically resistant. It has good acid and alkali resistance, sweat resistance, sea water resistance, dry cleaning resistance and abrasion resistance. It is often used in professional sportswear and Fitness clothes and the like require stretchable clothing to meet comfort requirements. [0003] At the same time, people are paying more and more attention to health. Studies have shown that small particle...
