Problems solved by technology

[0005] The technical problem to be solved by the present invention is the technical problem that the flame retardant performance of the existing phase-change temperature-regulating fabric is not good. It provides a preparation method of a flame-retardant phase-change heat insulation layer material for fire-fighting clothing. Microcapsules are mixed with flame-retardant adhesives, thickeners, and cross-linked flame retardants to prepare finishing solutions, which are attached to non-woven heat-insulating layer materials through post-finishing processes to prepare flame-retardant materials. and temperature-adjusted phase-change insulation layer fabric

Abstract

A preparation method of fire resistant phase transition thermal insulation layered fabric for firefighter clothing comprises the following steps of: immersing nonwoven felt prepared by combining 50-90% of aramid fiber 1313 fiber, 5-20% of carbon fiber and 0-30% of fire resistant viscose fiber into a prepared fire resistant phase transition microcapsule operating fluid, and carrying out two dipping and padding technology to obtain the fire resistant and temperature regulated phase transition thermal insulation layered fabric for firefighter clothing. A prepared phase transition finishing liquid contains 5-10% of an adhesive, 5-10% of a cross-linking fire retardant, 1-5% of a thickening agent and 1-5% of a fabric softener. The thermal insulation layered fabric which has undergone phase transition finishing is used to obviously raise thermal protective performance of firefighter clothing. The prepared fibrofelt fabric is applied in fire extinguishment and is also widely applied for individual protection equipment in different industries and fields such as metallurgy, petroleum, steel chemical industry, army war clothing and the like.

Description

technical field [0001] The invention relates to a manufacturing method of a phase-change fabric, in particular to a manufacturing method of a fabric material for a heat-insulating layer that is flame-retardant, temperature-adjustable, and can improve the thermal protection performance of firefighting clothing. Background technique [0002] Firefighting and combat uniforms with fire-resistant and heat-protective functions generally have a multi-layer structure. From the outside to the inside, there are flame-retardant and refractory material layers, waterproof and vapor-permeable layers, heat-insulating layers, and comfort layers. The selection of the heat-insulating layer must be To meet the contradictory needs of protection and comfort, the heat insulation layer material composed of thick non-woven refractory fiber felt can provide personal thermal protection for firefighters from high temperature and radiant heat damage, but the protective clothing made of this material has...
