Abstract

The invention discloses a preparation method of a firefighter uniform. The preparation method of the firefighter uniform comprises the steps of using sodium alga acid as a main material, soaking through zinc borate, growing mould, leaching through an NaHCO3 solution, deactivating enzyme, soaking with glycerol monostearate, and drying. The fire resistance, the heat insulation, the waterproofness and the air permeability of the firefighter uniform are improved.

Description

technical field [0001] The invention relates to the technical field of functional clothing production, in particular to a preparation method of firefighting clothing. Background technique [0002] When a fire breaks out, firefighters are the first-line people to go to the fire scene to rescue, so the safety of firefighters has been paid attention to, so the industry has developed a kind of firefighting clothing made of fireproof materials, so that firefighters can pass through the firefighting clothing itself. It has fireproof properties to protect yourself from the heat and fire burns generated in the fire scene. However, because firefighters frequently enter and exit the fire scene and need to stay in a high-temperature environment for a long time, the service life of the firefighting clothing is continuously reduced, and it is easy to be damaged. Therefore, the fire-fighting clothing not only needs to have excellent waterproof performance, but also has a certain flame-re...
