Abstract
An aqueous sizing composition having a cationic lubricant, amide compound, and cationic silicone polymer aqueous emulsion which is used to produce wet chopped sized glass fiber strands or which also has a film former to produce continuous glass fiber strands. The moisture content of the wet chopped glass fiber strands is controlled to within about 9 to about 20 weight percent. The sized wet chopped glass fiber strands have good flowability and when used to produce non-woven glass fiber strand mat, produces mat with good flexibility and tensile strength.
