    Abstract: Provided are a polymethylpentene conjugate fiber, which is capable of imparting to a lightweight polymethylpentene fiber an ability to develop a vivid and deep color, and a porous polymethylpentene fiber, which has a lightweight, a high pore diameter uniformity and a high porosity retention ratio against an external force, said polymethylpentene conjugate fiber and said porous polymethylpentene fiber being appropriately usable as a fiber structure for woven knitted goods, non-woven fabrics, yarns, cotton waddings, etc. The polymethylpentene conjugate fiber is characterized by having an island-in-sea structure wherein the sea component comprises a polymethylpentene-based resin and the island component comprises a thermoplastic resin. The porous polymethylpentene fiber, which comprises a polymethylpentene-based resin, is characterized in that the coefficient of variation (CV) of pore diameter at the fiber cross section is 1-50%.

    Abstract: A multi-layer woven or knitted fabric exhibiting reversibly changeable air permeability, which contains reversibly crimping cellulose acetate fibers exhibiting a percentage of crimp of less than 10% at a humidity of 95% or above and a percentage of crimp of 20% or above at a humidity of 45% or below and which has a basis weight of 100 to 350 g/m2. When water content of the fabric is enhanced by the absorption of water or moisture, the air permeability of the fabric increases to inhibit in-clothes stuffiness or stickiness due to sweat and in-clothes temperature rise, while when the fabric has discharged the water into the outside environment, the air permeability of the fabric decreases to the original one to prevent the body temperature from lowering excessively because of the heat of vaporization and thus keep the in-clothes environment comfortable.

    Abstract translation: 一种表现出可逆变化的透气性的多层机织或针织物，其含有可逆卷曲的醋酸纤维素纤维，其在95％或更高的湿度下的卷曲百分比小于10％，卷曲百分比为20％或更高 湿度为45％以下，基重为100〜350g / m 2。 当织物的含水量通过吸收水分或水分而增加时，织物的透气性增加，以防止由于汗水和衣物温度上升引起的衣服内的闷热或粘性，而当织物将水排出时 在外部环境下，织物的透气性降低到原来的透气度，以防止由于蒸发热而使体温过度下降，从而保持衣物中的环境舒适。
