Abstract

Abstract Natural and synthetic textile materials and blends thereof are disclosed containing at least one water-soluble, neutral alkanolamine, ammonium or mixed alkanolamine and ammonium salt of a phosphoric acid wherein said acid is selected from the group consisting of orthophosphoric acid and polyphosphoric acid. Polyester-cotton fabrics are rendered antistatic by treatment with these ionic bonded salts in the proportion of about 0.5 to about 10 percent by weight based on the weight of the textile fabric.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 106 words
An antistatic synthetic textile material or blend of natural and synthetic textile materials impregnated with an antistatic amount of an antistatic agent consisting essentially of at least one of (A) a neutral, ionically-bonded ammonium salt of an orthophosphoric acid, (B) a neutral, ionically-bonded ammonium salt of a polyphosphoric acid, (C) a neutral, ionically-bonded mixed ammonium and alkanolamine salt of orthophosphoric acid in which the alkanolamine is a 2 or 3 carbon atom alkanolamine or a mixture thereof and (D) a neutral, ionically-bonded mixed ammonium and alkanolamine salt of polyphosphoric acid in which the alkanolamine is a 2 or 3 carbon atom alkanolamine or a mixture thereof.
Claim 2
Dependent Claim 106 words
An antistatic synthetic textile material or blend of natural and synthetic textile materials impregnated with an antistatic amount of an antistatic agent consisting essentially of at least one of (A) a neutral, ionically-bonded ammonium salt of an orthophosphoric acid, (B) a neutral, ionically-bonded ammonium salt of a polyphosphoric acid, (C) a neutral, ionically-bonded mixed ammonium and alkanolamine salt of orthophosphoric acid in which the alkanolamine is a 2 or 3 carbon atom alkanolamine or a mixture thereof and (D) a neutral, ionically-bonded mixed ammonium and alkanolamine salt of polyphosphoric acid in which the alkanolamine is a 2 or 3 carbon atom alkanolamine or a mixture thereof.
