Multi-functional safety protection electric blanket made by polysulfonamide

Abstract

The invention discloses a multi-functional safety protection electric blanket made by polysulfonamide. The multi-functional safety protection electric blanket comprises a flexible heating element and thermal insulating layers arranged on upper and lower surfaces of the flexible heating element. Surfaces, away from the flexible heating element, of the thermal insulating layers are provided with flame-retardant fabric layers. A spun-laced non-woven fabric layer is arranged between the flexible heating element and a thermal insulating layer above the flexible heating element. In extremely-cold winter, the multi-functional safety protection electric blanket is electrified for heating such that a bed becomes warm and comfortable. At the general temperature in winter, excellent warming performance of polysulfonamide is given so that the effect of a warm mattress is fulfilled. The multi-functional safety protection electric blanket made by polysulfonamide has following beneficial effects: excellent flame-retardant and heat-insulating effects are obtained; the technical feature of the higher flame-retardant requirement for firefighter's protective clothing is satisfied such that the effect of safety protection of the blanket is achieved; and if family fire occurs, the invention can be used as a safe escape protection blanket for a family.

Description

technical field [0001] The invention relates to a polysulfone fiber multifunctional safety protection electric blanket. Background technique [0002] Electric blanket is a kind of contact electric heating appliance. It weaves or sews a special cable-type electric heating element with standard insulation performance into textile materials such as blankets in the shape of a snake, and emits heat when it is energized. It is mainly used to increase the temperature in the quilt when people sleep to achieve the purpose of heating. It can also be used for dehumidification and dehumidification of bedding. It consumes less power, has adjustable temperature, is easy to use, and is widely used, and has a history of more than 100 years. Since the electric blanket is heated in a relatively sealed space, it is easy to cause safety accidents when the temperature control element is abnormal or improperly used, mainly leakage, overheating and fire. [0003] At present, in order to improve...

AI Technical Summary

Problems solved by technology

In order to deal with the increasing fire situation caused by the burning of electric blankets, most of the existing technologies use flame-retardant polyester as the heat-insulating layer to improve the flame-retardant safety performance of electric blankets, but the structure of the heat-insulating layer is relatively simple. , the heat insulation effect is poor

Although flame retardant polyester also has a high limiting oxygen index value, it still has certain defects in high temperature resistance, that is, the fiber will shrink and fuse under local high temperature conditions, and lose its support for the outer fabric of the electric blanket or the bed. The flame-retardant and heat-insulating protective effect of the upper quilt may even form high-temperature molten droplets to cause damage to human skin, and it is difficult to solve the fire problem caused by the high temperature of the electric blanket.
