Coatings with Reduced Flammability for Linen Fabrics

The aim of this research is the investigation of burning characteristics and abrasion resistance of the Latvian local raw and bleached linen fabrics and the same fabrics with continuous anti flammable coating, containing commercial printing paste Printperfect EX-TS, pigment Bezaprint GELB (both of the producer CHT BEZEMA) and antimony trioxide (Sb2O3) as the flame-retardant additive. For the coating of the linen fabrics the flat screen method was used. After the coating 5 washing cycles were applied to the half of the fabrics. The burning test of the raw and the bleached linen fabrics and those coated with commercial printing paste and antimony trioxide, as well as the washed fabrics was accomplished. The results of the test shove, that the raw and the bleached linen fabrics burn completely. The flame extinction was observed for coated fabrics and coated washed fabrics. The abrasion resistance of coated fabrics depends on thickness of coating.
