Auto and aircraft seat cover fabric comprising regenerative natural fibers

Abstract

A novel pure natural and regenerative automotive and aircraft upholstery fabric made from linen and blends of linen and cotton, bamboo, wool and/or viscose with physiological and fastness properties comparable with those of currently-used materials and meeting all the requirements of the automobile and aircraft industry.

1 . An automotive or aircraft seat upholstery fabric made exclusively from renewable and environmental-friendly natural fiber material wherein the major component is linen. 
     
     
         2 . Automotive or aircraft seat upholstery fabric according to  claim 1 , characterized in that it consists of linen and additionally incorporated cellulose fibers such as cotton, bamboo and/or admixed viscose. 
     
     
         3 . Automotive or aircraft seat upholstery fabric according to  claim 1 , characterized in that it consists of at least 50% linen and the balance consists of cotton, bamboo and/or viscose filament in mixing ratio of cotton and/or other natural cellulose fibers each between 0 and 50% and viscose filament 0 up to maximum 50%. 
     
     
         4 . Automotive or aircraft seat upholstery fabric according to  claim 1 , characterized in that it consist of 50% linen and 50% cotton wherein up to 40% of cotton is replaced by viscose filament. 
     
     
         5 . Automotive or aircraft seat upholstery fabric according to  claim 1 , characterized in that each one of these fabrics has a weight between 100 and 700 g/m 2 , preferably between 200 and 600 g/m 2 . 
     
     
         6 . Automotive or aircraft seat upholstery fabric according to  claim 1 , characterized in that the fabric is washed, desized, demineralized, bleached and mercerized. 
     
     
         7 . Automotive or aircraft seat upholstery fabric according to  claim 1 , characterized in that the fabric is semi- or fully continuously dyed in pieces, or discontinuously by exhaustion dyeing as yarn or pieces. 
     
     
         8 . Automotive or aircraft seat upholstery fabric according of  claim 7 , characterized in that there are used high lightfast mono- or multifunctional reactive dyestuffs used as single dyestuffs and as components of a trichromy capable of meeting all fastness requirements of the automobile industry such as rubbing- and wet fastnesses. 
     
     
         9 . Automotive or aircraft seat upholstery fabric according to  claim 7 , characterized in that the fabric is dyed with a dye liquor in which is added 10-60 g/l of an acrylamide-based polymerization product for improving the through-dyeing and the dyestuff diffusion. 
     
     
         10 . Automotive or aircraft seat upholstery fabric according to  claim 9 , characterized in that it is padded with an additional finishing liquor containing 50-200 g/l of a special nature polyacrylate, 2-15 g/l of a fluorocarbon product (non-ionic) and from 0.2-2 g/l anionic wetting agent and optionally a softener product and then dried for 1 min at 150° C. and fixed. 
     
     
         11 . Automotive or aircraft seat upholstery fabric according to  claim 1 , characterized in that this fabric is padded or sprayed with a bactericide against decay and mold in a separate process and afterwards dried. 
     
     
         12 . Automotive or aircraft seat upholstery fabric according to  claim 1 , characterized in that this fabric is finished with a flame-resistant finishing based on a phosphate compound which impairs neither the light fastness (FAKRA) nor the rubbing fastness.
