Latex composition production method
A method for producing a latex composition, the method comprising a provision step of providing a conjugated diene polymer latex; a preparation step of adding a sulfur-based vulcanizing agent and a xanthogen compound to the conjugated diene polymer latex to prepare a latex composition before aging; and an aging step of, after the preparation of the latex composition before aging, aging the prepared latex composition before aging through storing of the latex composition at a temperature of 5 to 60 C. for 12 hours to 14 days, wherein the pH of the latex composition after 12 hours from the start of aging in the aging step is controlled to 9 or more.
Production method for dip-molded article
A method for producing a dip-molded article, including a dip-molding step of dip-molding a latex composition containing a latex of a carboxyl group-containing conjugated diene-based rubber (A) and a water-soluble metal compound (B) using a dip mold to form a dip-molded layer on the surface of the dip mold; a moisture content adjustment step of adjusting the moisture content of the dip-molded layer formed on the surface of the dip mold to 1 to 30 wt %; and a beading step of performing beading after the adjusting of the moisture content, the beading including peeling a portion of the dip-molded layer formed on the surface of the dip mold from the dip mold.
