Abstract
A method of co-texturizing glass fibers and thermoplastic fibers comprises passing a glass fiber strand through a texturizing gun, simultaneously passing a thermoplastic fiber strand through the texturizing gun with the glass fiber strand and injecting pressurized air into the texturizing gun concurrently with the glass fiber strand and thermoplastic fiber strands. This method produces a co-texturized fiber material comprising between 20-85% by weight glass fiber and 15-80% by weight thermoplastic fiber having an overall density of from about 20 grams/liter to about 200 grams/liter, and preferably from about 20 grams/liter to less than about 30 grams/liter.
