## Abstract

Cocoa amine acetate and a polyamide condensate, in combination as a lubricant in a glass size, result in glass strands exhibiting less fuzz than does glass sized with a size containing either of the two components, individually.

## Claims

### Claim 1

Glass strands having their surface in contact with residue formed by removing water from an aqueous size composition comprising a polyester and a lubricant system comprising cocoa amine acetate and a polyamide condensate comprising polyethyleneimine.

### Claim 2 (depends on 1)

Glass strands having their surface in contact with the residue formed by removing water from the composition of claim 1 in which said cocoa amine acetate and said polyamide each comprise about 50 weight percent of said lubricant system.

### Claim 3 (depends on 1)

A glass-reinforced molded product comprising glass fibers sized with the composition of claim 1.

### Claim 4 (depends on 2)

A glass-reinforced molded product comprising glass fibers sized with the composition of claim 2.

### Claim 5 (depends on 1)

A method of producing a molded article which comprises incorporating into a moldable unsaturated polyester resin composition the glass strands of claim 1 and molding the resulting composite under heat and pressure.

### Claim 6 (depends on 2)

A method of producing a molded article which comprises incorporating into a moldable unsaturated polyester resin composition glass strands sized with the aqueous size composition of claim 2 and molding the resulting composite under heat and pressure.
