ABSTRACT:
In a method of making spun yarn from staple fibers, a mix is formed which includes synthetic plastic staple fibers of at least three different titers. One of these titers is a medium titer which is within a range of 6 microns of the average titer of the synthetic plastic fibers in the mix. Another titer is a fine titer which is at most about 15 microns less than the average titer of the synthetic plastic fibers in the mix. The third titer is a coarse titer which is at most about 15 microns in excess of the average titer of the synthetic plastic fibers in the mix. The fibers of medium titer constitute a minimum of about two-thirds of the weight of the synthetic plastic fibers in the mix. The thus-formed mix of fibers is subjected to a spinning operation so as to convert it into a spun yarn. The selection of the titers as outlined enables a spun yarn of synthetic plastic fibers to be obtained which, to the touch, feels like a yarn made of natural fibers.
