    Abstract: A molded antimicrobial article comprises an infiltrated antimicrobial agent which forms independent phases of 0.01 mu m or more in shorter diameter in the molded article. It is preferable that the antimicrobial agent is a pyridine based antimicrobial agent with a molecular weight of 200 to 700 and an inorganic property/organic property value of 0.3 to 1, and that 50% or more of the antimicrobial agent is infiltrated in a depth range of 0.5, preferably, 1 mu m or more from the surface of the molded article, or that 30% or more of the antimicrobial agent is infiltrated in a depth range of 2 mu m or more from the surface of the molded article. It is also preferable that the molded article is fibers, that the surface area used per 1 g of fibers is 0.1 m or more, and that the synthetic fibers are a colored antimicrobial fibrous product. The molded antimicrobial article of the present invention can be obtained, for example, by immersing a fibrous product in a dyeing liquid containing a pyridine based antimicrobial agent with a molecular weight of 200 to 700, an inorganic property/organic property value of 0.3 to 1.4 and an average particle size of 2 mu m or less, and treating simultaneously with dyeing under pressurization, or by applying a liquid containing a pyridine based antimicrobial agent with a molecular weight of 200 to 700, an inorganic property/organic property value of 0.3 to 1.4 and an average particle size of 2 mu m or less to a fibrous product by padding or spraying, and heat-treating it at 160 to 200 DEG C in dry or wet state.

    Abstract: The present invention relates to a heat-retaining fiber structure comprising a cloth layer having a moisture/heat release control capability laminated with a cloth layer having water molecule adsorption/heat release capability, wherein said cloth layer having the moisture/heat release control capability has a moisture permeability of 3000-12000g/m .24hr and said cloth layer having water molecule adsorption/heat release capability has an exothermic energy index of 5 or larger and a contact thermal sensation factor (qmax) of 0.1W/cm or less. This constitution makes it possible to provide clothing having high heat-retaining performance achieved by water molecule adsorption capability.

    Abstract: A method of modifying a synthetic or natural polyamide product, such as a fiber cloth, film or leather, wherein a graft polymerization is carried out on said product in an aqueous solution containing 5 to 60 mole % of carried acid and 95 to 40 mole % of methacrylic acid as monomer or by adding said aqueous solution to the polymerization system. The method provides an industrial-ly feasible and efficient means of graft polymerization of polyamide products by greatly improved grafting efficiency of acidic vinyl monomers to the product.
