Problems solved by technology

The main problem lies in the heat insulation layer. In the prior art, non-woven structures with a certain degree of bulkiness are mostly used, such as flakes, needle-punched felts, spunlace felts, etc., but this structure is particularly easy to absorb water, which increases the wearer's comfort. Load and humidity stress, and not resistant to washing, easy to break

Abstract

The invention discloses 3D flame-retardant fabric and a heat protection garment thereof. The fabric comprises a single-layer portion and a double-layer portion which are in parallel and alternate arrangement. The fabric is made of high-performance flame-retardant yarns and flame-retardant elastic covering yarns, and is formed through interweaving of the yarns by a weaving or warp knitting technology according to a weave diagram. The double-layer portion comprises a surface layer and an inner layer which are completely separated from each other. The inner layer is made of the high-performance flame-retardant yarns and the flame-retardant elastic covering yarns. The surface layer is made of the high-performance flame-retardant yarns. Through arraying of connection joints of the single-layerportion and the double-layer portion under the action of the flame-retardant elastic covering yarns, the surface layer and the inner layer are different in stress rebound resilience of raw materials,and are separated from each other, so that a 3D air cavity protrusion structure is formed at the separation position. The heat protection garment comprises the 3D flame-retardant fabric, or comprisesa heat-insulating comfort layer, a waterproof breathable layer and a flame-retardant outer layer from inside to outside sequentially. The heat-insulating comfort layer, the waterproof breathable layerand the flame-retardant outer layer are made of the 3D flame-retardant fabric.

Description

technical field [0001] The invention relates to the technical field of textile fabrics and clothing, in particular to a 3D flame-retardant fabric and thermal protective clothing. Background technique [0002] For a long time, people have encountered thermal injuries caused by various fires, explosions, high-temperature furnace arcs, molten metal splashes, welding arcs and other heat sources in activities such as production, life, rescue, and war. The heat energy of these heat sources can cause fatal harm to the human body through contact, radiation or convection. Through the protection of fabrics and clothing, blocking heat energy from reaching the surface of the human skin will be the most direct and effective means of protection to protect the human body from harm. [0003] In harsh environments with high heat flux density, in order to block the heat source from burning the human body, thermal protection products are usually configured with a combination of multi-layer st...
