TLDR
In this article, the subject fiber having excellent moisture absorptivity, moisture permeability and heat-insulation property and a feeling similar to natural fiber was obtained by kneading superfine powder of an animal protein fiber and superfine powder of far infrared-radiation substance to a polymer such as synthetic fiber and spinning the kneaded mixture.Abstract:
PURPOSE:To obtain the subject fiber having excellent moisture absorptivity, moisture permeability and heat-insulation property and a feeling similar to natural fiber by kneading superfine powder of an animal protein fiber and superfine powder of far infrared-radiation substance to a polymer such as synthetic fiber and spinning the kneaded mixture CONSTITUTION:Superfine powder of an animal protein fiber 2 (eg collagen fiber) and superfine powder of far infrared-radiation substance 3 (preferably aluminum, etc) are kneaded to one or more kinds of polymers 10 selected from synthetic fiber (preferably nylon, etc), semisynthetic fiber (preferably acetate fiber) and regenerated fiber (preferably rayon) and the kneaded mixture is spun (preferably core-sheath conjugate spinning using the kneaded composition as the core or the sheath component) to obtain the objective fiber The moisture- absorptivity and permeability, etc, can be further improved by adding superfine powder of a water-soluble substance (preferably water-soluble gelatin, etc) to the kneaded composition, kneading the mixture, spinning the composition and removing the water-soluble substance from the spun fiber by washing with water to form a number of through holesread more
