Abstract
Composite yarns, comprising one or more elastomeric fibers and hard yarns, are formed by adhering the elastomeric fibers and hard yarns together using a size material. The size-covered composite yarn can be used in weaving and knitting to make stretch fabrics with desired garment characteristics. The size material may be removed by subsequent wet fabric processing.

A method for making a composite yarn, comprising:
- stretching a strand of one or more elastomeric fibers in a range from 1.1× to at least 5× of a relaxed length of the strand;
- aligning at least one hard yarn selected from the group consisting of synthetic fibers, natural fibers and a blend of synthetic and natural fibers, adjacent and substantially parallel to said stretched strand to form an aligned yarn;
- applying a size material to said aligned yarn;
- and
- drying or curing the size material to form a composite yarn.
