Abstract
The present invention reduces the minimum detectable volume of a piece of a glove in the detection using a metal detector. A glove made of a rubber or resin film which contains magnetic particles, wherein the quantity of the magnetic particles is 0.2 to less than 40 mass % relative to the whole of the film; and the magnetic particles comprise secondary particles formed by the agglomeration of primary particles.
Claims9
A glove containing magnetic particles in a glove film formed from rubber or resin, wherein the magnetic particles are at least 0.2 mass % but less than 40 mass % in terms of the glove film as a whole, the magnetic particles include secondary particles of aggregated primary particles, the average particle diameter of the primary particles is no more than 1 μm, and the proportion by volume of particles where the particle diameter of the secondary particles exceeds 1 μm is at least 20 vol % in terms of the combined volume of particles as a whole.
A method for manufacturing a glove by an immersion method, comprising:
- a process wherein magnetic particles where the average particle diameter of primary particles is no more than 1 μm are dispersed in a solvent to prepare a magnetic particle dispersion;
- a process wherein the magnetic particle dispersion is added to an emulsion containing rubber or resin, to prepare an emulsion containing magnetic particles in which the magnetic particles are at least 0.2 mass % in terms of the total solids component;
- and
- a process wherein, by using the emulsion containing magnetic particles, there is produced a glove containing secondary particles of aggregated primary particles in which the magnetic particles are at least 0.2 mass % but less than 40 mass % in terms of a glove film as a whole, and the proportion by volume of particles where the particle diameter of the secondary particles exceeds 1 μm is at least 20 vol % in terms of the combined volume of particles as a whole.
