The invention also relates to textile materials which are obtainable by the method according to the invention.

Claims

exact text as granted — not AI-modified
1 . Method of modifying the odour properties of textiles, characterized in that the textile is treated with an amylose-containing substance with an amylose content of at least 30% by weight.  
     
     
         2 . Method according to  claim 1 , characterized in that the textile is additionally treated with a fragrance.  
     
     
         3 . Method according to  claim 1 , characterized in that the amylose-containing substance is used together with a film-forming, water-insoluble polymer.  
     
     
         4 . Method according to  claim 1 , characterized in that the amylose-containing substance is used in an amount of from 0.5 to 25% by weight, based on the weight of the textile.  
     
     
         5 . Method according to  claim 1 , characterized in that the textile is treated with the amylose-containing substance in aqueous liquor.  
     
     
         6 . Method according to  claim 5 , characterized in that the aqueous liquor additionally comprises an interface-active substance which is suitable for dispersing the amylose-containing substance.  
     
     
         7 . Method according to  claim 5 , characterized in that the aqueous liquor comprises the polymeric or oligomeric dispersant in an amount of from 0.5 to 20% by weight, based on the amylose-containing substance.  
     
     
         8 . Method according to  claim 5 , characterized in that the aqueous liquor comprises the amylose-containing substance in a concentration of from 1 to 40% by weight, based on the weight of the liquor.  
     
     
         9 . Textile material obtainable by a method according to  claim 1 .  
     
     
         10 . Use of amylose-containing substances with an amylose content of at least 30% by weight for modifying the odour properties of textiles.
