Abstract

The invention relates to hollow fibers, and specially, relates to novel hollow health-care fibers with a high hollow rate, degradable performances and lasting health-care effects, and a preparation method thereof. The novel hollow health-care fibers are characterized in that the novel hollow health-care fiber are prepared from sea-island fibers through peeling, wherein a sea component is a mixed component comprising polyesters of polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), polybutylene terephthalate (PBT) and the like, a polylactic acid (PLA) and a polyvinyl alcohol (PVA), and an island component comprises a low-molecular weight PVA and a low-molecular weight PLA; tourmalinite particles are added into inner cavities so that a fluffy and soft handle is obtained; and the novel hollow health-care fibers are added with far-infrared negative ions and thus having lasting health-care effects. The preparation method of the novel hollow health-care fibers comprises putting sea-island fibers into hot water at a temperature of 100 to 150 DEG C under 1 to 5 times atmospheric pressure to be boiled for 0.5 to 3 hours, taking out the boiled sea-island fibers, and drying to obtain the novel hollow health-care fibers. The preparation method has the advantages of simple process, no pollution in production, and good adaptability for large-scale production.

Description

Technical field [0001] The invention relates to a hollow fiber, in particular to a hollow fiber with high hollow ratio, degradable and long-lasting health care effect. Background technique [0002] Polyester has gradually attracted people's attention due to its excellent physical and chemical properties, and its products have become more and more widely used. However, due to the single synthesis and processing technology of ordinary polyester fibers, the prepared monofilament has a single cross-sectional shape and lacks cotton-like properties. , hemp and other natural fibers have a variety of cross-sectional shapes, so the effect of temperature insulation and hand feeling has been unsatisfactory. At the same time, due to the single function, the ordinary fibers produced by traditional techniques are seriously challenged. [0003] In order to achieve heat preservation and feel similar to natural fibers, the usual method is to produce shaped yarns, that is, to produce fibers ...
