Problems solved by technology

However, in the actual use of the fabrics obtained by the above two methods, the release efficiency of negative ions is limited, so the health care effect is not obvious.
Moreover, for the impregnation treatment process, such as the scheme of CN201810406028.3, the negative ion powder is also easy to fall off during the subsequent use or washing process, which affects the health care effect
In addition, in the two methods, due to the addition of negative ion powder, at least part of the powder will be fixed on the surface of the fiber, resulting in a rough surface of the fiber and a feeling of burrs. Poor experience

Abstract

The invention relates to the field of fiber materials, and discloses a skin-core structured anion moisture-absorption health-care functional fiber and a preparation method thereof. The skin-core structure of the fiber is formed by a porous hydrophobic skin layer and a hydrophilic core layer; and the porous hydrophobic skin layer is PET, PP or PA, the hydrophilic core layer is hydrophilic polyester containing a moisture storage cavity, and negative ion powder is contained in the moisture storage cavity. The anion moisture-absorption health-care functional fiber has the characteristics that the anion powder is firmly loaded and washable, the anion release efficiency is high, and the skin fitting property is good.

Description

technical field [0001] The invention relates to the field of fiber materials, in particular to a skin-core structure negative ion moisture-absorbing health-care functional fiber and a preparation method thereof. Background technique [0002] Negative ion material is a powder material that can generate negative air ions, usually composed of rare earth elements, tourmaline powder and other substances. Among them, tourmaline is the most typical negative ion powder. When the pressure or temperature on the surface of the tourmaline gas crystal changes, the potential difference of the tourmaline crystal will be caused, the surrounding air will be ionized, and the hit electrons will act on the adjacent water. and oxygen molecules and convert it into negative ions. This naturally occurring negative oxygen ion has a health-care effect and is good for human health. [0003] With the development of technology and the improvement of people's daily life quality, various products with h...
