The invention relates to the technical field of
condom production, in particular to a process for producing an ultrathin
condom based on a four-time gum dipping method, which comprises the following steps: according to the components and parts by weight of the
condom, blending to obtain a solution A, a solution B, a solution C and a solution D with different latex
solubility; condom linkage
machine production is carried out, wherein preparation work before production is carried out; the mold is fed into a latex tank containing the latex solution A to be dipped and dried; feeding into a latex tank containing a latex solution B, dipping and
drying; feeding into a latex tank containing a latex solution C, dipping and
drying; and finally, feeding the condom into a latex tank containing a latex solution D for gum dipping and
drying to obtain a semi-finished condom, and sequentially carrying out edge
curling, re-drying,
alkaline water dipping, demolding,
powder water soaking and washing, drying and shaping, spreading and airing and electric detection on the semi-finished condom to obtain the finished ultrathin condom. The multiple aspects such as
gram weight, thickness and strength of the condom product obtained by the method are superior to those of a condom product prepared by a high-
solid-content three-time impregnation method.
