Technical field
The present invention relates to the flame protections such as petrochemical industry, mine, metallurgy, steel, shipbuilding, electric power, the labor protection skills of thermal protection
Art field, more particularly to a kind of fire-retardant blend of comfort type arc protection.
Background technology
Arc protection clothes are broadly divided into two kinds, and a kind of is for being particularly easy to occur the workplace of electric arc electric discharge or electrification
It is closed or disconnects the arc protection clothes tight from top to bottom that electric brake is needed when operations；Another kind is relatively much bigger
Spatial dimension in, it may occur however that the energy level of electric arc is relatively low, and occurrence frequency is relatively low, and the routine work of arc protection is needed to take.
The design philosophy of two kinds of arc protection clothes differs greatly.Former mainly considers that the performance of arc protection is high, and protection is tight, wearing
Comfort and convenience relative importance value it is not high, just worn temporarily when specific operation is done in specific region；Latter is as daily
Work clothes will be worn always from going to work to coming off duty, and target user is very huge, and arc performance requirement is relatively low, but to anti-
It is the comfort of electric arc, convenience, Eco-power more demanding.In design, for former arc protection clothes, generally using multilayer
Fabric or the method for increasing fire-retardant interlayer, that is, increase the thick of arc protection to reach extra high arc protection requirement,
Implement simple instead.Design for latter protective garment is difficult instead, and the region of hot weather, humidity are got over
Height, easier generation electric arc, particularly summer need thinner clothes, but clothes are thinner, arc resistance relatively lower.With money fabric
Prevention of arc can substantially with the linear positive correlation of the Gram Mass of the fabric.How the arc protection water of needs can guarantee
It is flat, the thickness of protective garment or protective fabric is reduced, improves the important directions that comfort property is arc protection clothes research.
There are mainly three types of solutions for existing market product：
The first is based on modacrylic, aramid fiber and minimal amount of antistatic fiber is mixed into, such as E.I.Du Pont CompanyProduct, 100% has used the fiber hardly to absorb water, and arc value is higher, can only be by reducing square Mick of fabric
Comfort is improved again, adjusting range is limited；
It is for second that aramid fiber and phosphorous flame-retardant viscose glue mix anti-system, the substantially content of aramid fiber is 35%~65%, phosphorus system
