Dependences of Polypropylene Fabric Air Permeability and Flammability on the Yarn Structure and Air Pressure in a Texturing Jet
Keywords:air textured yarn, woven fabrics, flammability.
The flammability and air permeability of woven fabric are very important properties for upholstery furniture
manufacturers. In this study the dependencies of air permeability and flammability on yarn air texturing parameters, such
as structure of the yarn and air pressure in the texturing jet were investigated. It was found, that air permeability depends
more on yarn structure, than on air pressure in the texturing jet. Difference of air permeability of the fabrics in
dependence of different structure yarns is around 17 %, when in dependence of air pressure is just 3 %. The same
tendency was stated regarding fabric self extinction time. Self extinction time variation because of structure is around
19 %, and because of pressure in some cases less than 3 %. Also it was noted, that air permeability and self extinction
time depends on hairiness of the yarn woven into the fabric.
