Abstract
Abstract Antisoil nylon fibers are provided by first coating the fibers with a polyacrylic acid and then with a fluorochemical. The polyacrylic acid chemically bonds to the curface of the fibers and to the fluorochemical. The resulting coating has greater adherence to the fiber than does corresponding coatings from which the polyacrylic acid is omitted.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
103 words
In a process for coating the surface of nylon fibers with fluorochemical particles to enhance the water and oil repellency of the fibers wherein the fibers are treated with an aqueous dispersion of positively charged colloidal particles of the fluorochemical(s) and then dried to leave the fluorochemical particles on the surface of the fibers, the improvement of enhancing the fixation of the particles to the surface of the fibres which comprises the preliminary step of coating the fibers with a material which chemically bonds to the surface of the fibers and will chemically bond to the fluorochemical particles when brought into contact therewith.
Claim 2
Dependent Claim
103 words
In a process for coating the surface of nylon fibers with fluorochemical particles to enhance the water and oil repellency of the fibers wherein the fibers are treated with an aqueous dispersion of positively charged colloidal particles of the fluorochemical(s) and then dried to leave the fluorochemical particles on the surface of the fibers, the improvement of enhancing the fixation of the particles to the surface of the fibres which comprises the preliminary step of coating the fibers with a material which chemically bonds to the surface of the fibers and will chemically bond to the fluorochemical particles when brought into contact therewith.
Claim 3
Dependent Claim
29 words
A process of Claim 1, wherein the material is applied to the fibers from an aqueous medium, and the fibers are dried before they are treated with the fluorochemical.
Claim 4
Dependent Claim
14 words
A process of Claim 1 or Claim 2, wherein the material comprises polyacrylic acid.
Claim 5
Dependent Claim
14 words
The process of Claim 1 or Claim 2, wherein the material comprises polymethacrylic acid.
Claim 6
Dependent Claim
38 words
A process according to any of the preceding claims, wherein the material is applied to the fibers from an aqueous medium comprising from 5 x 10 -3 to 5 x 10 -2 moles per litre of the material.
Claim 7
Dependent Claim
28 words
A coated nylon fiber characterized in that the coating comprises a material chemically bonded to the surface of said fiber and fluorochemical particles chemically bonded to the material.
Claim 8
Dependent Claim
28 words
A coated nylon fiber characterized in that the coating comprises a material chemically bonded to the surface of said fiber and fluorochemical particles chemically bonded to the material.
Claim 9
Dependent Claim
12 words
A coated fiber of Claim 6, wherein the material comprises polyacrylic acid.
Claim 10
Dependent Claim
12 words
A coated fiber of Claim 6, wherein the material comprises polymethacrylic acid.
