The invention discloses a production technology for a sleeping bag. The sleeping bag comprises a fabric layer and a latex layer clamped in the fabric layer. A production technology of the emulsion layer comprises the following steps: firstly, batching raw materials of the latex layer by using the following components: 0 to 100 parts by weight of natural latex, 0 to 100 parts by weight of styrene-butadiene latex, 2 to 4 parts by weight of emulsifier, 5 to 9 parts by weight of vulcanizing agent, 4 to 6 parts by weight of zinc oxide, 3 to 5 parts by weight of foaming agent, 0.8 to 1.5 parts by weight of potassium pyrophosphate and 3 to 5 parts by weight of sodium fluosilicate, wherein the components at least contain one of the natural latex and the styrene-butadiene latex; secondly, curing the raw materials of the latex layer for 2 to 6 hours under the condition that the temperature is 26 to 30 DEG C; thirdly, carrying out foaming treatment on the cured raw materials of the latex layer; fourthly, pouring the foamed raw materials of the latex layer on a template and then condensing; fifthly, vulcanizing the condensed raw materials of the latex layer; sixthly, carrying out water washing on the vulcanized raw materials of the latex layer; seventhly, drying the washed raw materials of the latex layer. According to the sleeping bag provided by the invention, the problems of poor flexibility, poor air permeability and high possibility of growing mites on the sleeping bag in the prior art can be effectively solved.
