This invention relates to a process for combining a low melting binder fiber with a continuous filament base yarn to form a composite yarn having good bulk and a high level of interlace. More particularly, the process involves bulking a continuous filament yarn, combining it with the low-melting binder fiber, interlacing the combined yarn, and then fixing the interlace.
