Lining capable of adjusting space temperature in firefighter uniform and manufacturing method of lining

Abstract

The invention discloses a lining capable of adjusting the space temperature in a firefighter uniform and a manufacturing method of the lining. A fabric layer and a plurality of buffering temperature adjusting protrusions are included. The multiple buffering temperature adjusting protrusions are fixed to the side face of the fabric layer at equal intervals, and the part, between every two adjacentbuffering temperature adjusting protrusions, of the fabric layer is provided with ventilation holes. Each buffering temperature adjusting protrusion is internally provided with an inert gas containingcavity and a phase change material containing cavity. After food-grade silica gel is subjected to extrusion molding and fusion through an extruder, a membrane is formed in a forming mold and extruded; the buffering temperature adjusting protrusions are formed after treatment, the inert gas containing cavities are inflated with nitrogen, and the phase change material containing cavities are filledwith phase change materials; and finally, the buffering temperature adjusting protrusions are sewn to the side face of the fabric layer, the ventilation holes are punched through a mechanical punching device, and the lining is manufactured. On the premise that a good cooling effect is guaranteed, the lining is light in structure and convenient to wear and use, and meanwhile the lining has good buffering capability; and accordingly the personal safety and work efficiency of firemen in the high temperature environment are improved.

Description

technical field [0001] The invention relates to a fire-fighting clothing inner lining and a preparation method thereof, in particular to an inner lining capable of adjusting the temperature of the inner space of the fire-fighting clothing and a manufacturing method thereof. Background technique [0002] Fire is a major disaster that affects social stability and threatens people's property safety. It has the characteristics of unpredictable occurrence time, rapid fire spread and large losses. At present, fire-fighting facilities are installed in each building to prevent and respond to fires, but fire-fighting and rescue tasks are still completed by people using fire-fighting facilities and tools. In the fire scene, the high temperature will cause some building wall decorations to fall off and structures to deform and break, which will eventually lead to the production of falling objects in the fire scene, which will endanger the personal safety of firefighters. In addition,...

However, this kind of overalls cannot withstand the impact caused by external accidents, and has poor cushioning performance.

The Chinese utility model patent with the notification number CN203842203U discloses a new type of fire-fighting clothing fabric, which is composed of a flame-retardant layer, a heat-insulating layer, a waterproof layer and an inner lining layer. The protective layer can effectively isolate the external heat and prevent burns, but the water vapor generated by the evaporation of water in a high-temperature environment will cause the internal environment humidity between the human body and the protective layer to be relatively high, resulting in a decrease in the perspiration rate of the human skin and making the human body feel stuffy, which not only affects Comfortable to wear, and reduce the labor intensity of firefighters; in addition, the total weight of the fabric increases after adding water, which is also not conducive to the actions of the wearer
