  • Publication number: 20220022566
    Abstract: The present invention relates to a swimsuit 23 including an elastic polyurethane yarn. The elastic polyurethane yarn contains; 0.5 to 10 mass % of a cationic high-molecular-weight compound A having a number-average molecular weight of 2000 or more; and an inorganic chlorine deterioration inhibitor B. The mass ratio of the cationic high-molecular-weight compound A to the inorganic chlorine deterioration inhibitor B ranges from 0.3 to 3, and a silicone oil is applied to the elastic polyurethane yarn. A fabric for the swimsuit is treated with water repellent finishing. The swimsuit 23 preferably includes an elastic polyurethane yarn whose ratio of fluorine (F) to carbon (C) on the elastic polyurethane yarn is 0.030 or more in an elemental mass concentration according to scanning electron microscope-energy dispersive X-ray spectroscopy (SEM-EDX). Thereby, it is possible to provide a swimsuit with high water repellency, low water retention rate, and high buoyancy.

  • Patent number: 8277941
    Abstract: The present invention provides elastic polyurethane yarns which possess excellent elongation, recoverability, heat resistance and chemical resistance, as well as a method of manufacturing the same. The elastic polyurethane yarns comprise a polyurethane being composed mainly of a polymeric diol and a diisocyanate, and contains through incorporation a compound having within the molecule a phosphorus-nitrogen interatomic bond(s). The process can produce the elastic polyurethane yarns by adding to a solution of the polyurethane a compound having within the molecule a phosphorus-nitrogen interatomic bond(s), followed by spinning.
