Method of treating discontinuous fibers

摘要

Discontinuous fibers are entrained in a gaseous medium and coated while entrained with a substantially continuous coating of a binder material. Plural coatings of various binder materials may be applied to the entrained fibers. Also, one or more solid particulate materials may be adhered to the fibers by the binder material as the binder material dries. The binder material may be heat bondable and mixed with other fibers for use in producing a wide variety of products.
