Firefighter protection suit outer layer fabric and manufacturing method thereof

Abstract

The invention relates to firefighter protection suit outer layer fabric and a manufacturing method thereof, and belongs to the technical field of textile fabric. The firefighter protection suit outer layer fabric can be obtained in the way that the surface of finished aramid fiber fabric is coated with a layer of alumina gel. The alumina gel comprises, by mass, 3-6 parts of powdered aluminum, 65-70 parts of waterborne polyurethane emulsion, 20-30 parts of polyvinyl acetate emulsion, 2-4 parts of nano silica powder, 10-15 parts of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide, 15-19 parts of polyving akohol, 10-15 parts of ethanol and 5-10 parts of water. The firefighter protection suit outer layer fabric not only has excellent high-temperature resistance and thermal protective performance but also has excellent fire resistance; moreover, the softness and comfortableness are high, the air permeability is splendid, and great wearing comfortable sensation is given to firefighters.

Description

technical field [0001] The invention belongs to the technical field of textile fabrics, and in particular relates to an outer layer fabric of a fireman's protective clothing and a manufacturing method thereof. Background technique [0002] The outer fabric of the traditional firefighter's protective clothing is mainly composed of three layers of materials, namely aluminum foil, PET polyester film and aramid fiber base cloth. With the continuous development of technology, in order to improve the air permeability and In terms of comfort, there are currently many protective clothing outer fabrics that are directly compounded with aluminum foil and aramid base fabric. The outer fabric of the firefighter's protective clothing must have excellent high temperature resistance, flame retardancy and comfortable breathability. Although the outer fabric of the fireman's protective clothing made of aluminum foil directly combined with aramid base fabric has excellent high temperature re...

AI Technical Summary

Problems solved by technology

Although the outer fabric of the fireman's protective clothing made of aluminum foil directly combined with aramid base fabric has excellent high temperature resistance and flame retardancy, it is still difficult to master its compounding process. At present, only a few manufacturers in China have its own Core technology, in addition, although aluminum foil can give the outer fabric better fire resistance and flame retardancy, its comfort is poor, and its air permeability is not satisfactory. Moreover, although the currently used aramid fabric has excellent performance, it is Its softness, breathability, and even flame resistance still need to be further improved. Improving the performance of aramid fabrics can further improve the overall fire resistance and comfort performance of the outer fabric of firefighters' protective clothing, because once the outer layer of firefighters' protective clothing The thermal protection performance and air permeability of the fabric are poor, and the sweat emitted by firefighters during the battle will be blocked. Coupled with the extremely high external ambient temperature, firefighters will have a great sense of stuffiness, which will seriously affect firefighters. combat efficiency
