According to needs, sometimes in order to increase the flexion strength of chemical fiber fabrics and improve the feel of the fabric, 15 to 100 very fine monofilaments are commonly used to combine into multiple fibers. When spinning, compressed air is used to blow the silk strips loose and make them rotate, twist and form many network points, which is the high-strength polypropylene intermingled yarn.

High strength polypropylene intermingled yarn has network nodes, and the fabric woven with it is thick and has a woollike texture on the surface.

High strength polypropylene intermingled yarn has a high strength, which eliminates the need for sticking and sizing during weaving, so intermingled yarn is also known as "no sizing yarn".
