Abstract

Durable antistatic properties are imparted to fabrics of synthetic polymers such as nylon and polyester by forming on said fabric a water insoluble reaction product of a melamine formaldehyde resin with certain ethoxylated quaternary ammonium salts and amine compounds. A urea formaldehyde resin can optionally be included as a third component of the reaction product. In a preferred embodiment, the fabric having the reaction product thereon is washed with a solution containing an anionic surfactant.

Claims

1. A process of imparting durable antistatic properties to synthetic polymer fabric which comprises applying to said fabric an aqueous composition containing

(A) an ethoxylated compound selected from the group consisting of compounds having the formula ##STR12## wherein R₁ is an alkyl group of 8 to 22 carbon atoms;

R₂ is an alkyl group of 1 to 22 carbon atoms or --(CH₂ CH₂ O)_r R₄ ;

R₃ is hydrogen, --CH₂ CH₂ NH₂ or --CH₂ CH₂ SH;

R₄ is hydrogen, --CH₂ CH₂ NH₂, --CH₂ CH₂ SH or an alkyl group of 1 to 4 carbon atoms;

n, p and r are integers of from 5 to 60, and

X^- is an anion and

(B) A melamine derivative of the formula ##STR13## where R₅ at each occurrence is independently selected from the group consisting of hydrogen and --CH₂ OZ with Z being hydrogen or alkyl of 1 to 4 carbon atoms, provided that at least two of said R₅ groups are --CH₂ OZ,

and heating said fabric to coreact said ethoxylated compound and said melamine derivative.

2. A process as claimed in claim 1 wherein said aqueous composition additionally includes a urea-formaldehyde resin.

3. A process as claimed in claim 2 wherein said urea-formaldehyde resin is selected from the group consisting of dimethyloldihydroxyethyleneurea, dimethylolethyleneurea and urons.

4. A process as claimed in claim 1 wherein said aqueous composition contains an acid or acid forming salt which serves as a catalyst.

5. A process as claimed in claim 1 wherein said aqueous composition contains a nonionic surfactant.

6. A process as claimed in claim 1 wherein subsequent to the coreaction of said ethoxylated compound and said melamine derivative, said fabric is washed with an aqueous solution of an anionic surfactant.

10. A synthetic polymer fabric having deposited thereon a water insoluble antistatic composition comprising the reaction product of the melamine derivative and the ethoxylated compound of claim 1.

7. A process of imparting durable antistatic properties to synthetic polymer fabric which comprises applying to said fabric an aqueous composition containing

(A) an ethoxylated compound selected from the group consisting of compounds having the formula ##STR14## wherein R₁ is an alkyl group of 8 to 22 carbon atoms;

R₂ is an alkyl group of 1 to 22 carbon atoms or --(CH₂ CH₂ O)_r R₄ ;

R₃ is hydrogen, --CH₂ CH₂ NH₂ or --CH₂ CH₂ SH;

R₄ is hydrogen, --CH₂ CH₂ NH₂, --CH₂ CH₂ SH or an alkyl group of 1 to 4 carbon atoms;

n, p and r are integers of from 5 to 60, and

X^- is an anion, and

(B) A melamine derivative of the formula ##STR15## where R₅ at each occurrence is independently selected from the group consisting of hydrogen and --CH₂ OZ with Z being hydrogen or alkyl of 1 to 4 carbon atoms, provided that at least two of said R₅ groups are --CH₂ OZ, and

(C) a catalyst which is an acid or an acid forming salt, heating said fabric at a temperature of about 120°

to 250°

C. to form an insoluble product on said fabric by coreaction of said ethoxylated compound and said melamine derivative and washing said fabric with an aqueous solution of anionic surfactant.

8. A process as claimed in claim 7 wherein said aqueous composition additionally includes a urea-formaldehyde resin.

9. A process as claimed in claim 7 wherein said aqueous composition contains a nonionic surfactant.
